Red Light Therapy for Women's Health: 10 Ways It Can Support Your Body
Introduction Women's health is remarkably complex. Across a lifespan, the female body navigates hormonal cycles, reproductive transitions, and chronic pain conditions that are often underprioritized in conventional medicine. Red Light Therapy (RLT) is one tool that spans a surprisingly wide range of these challenges. RLT uses specific wavelengths of red and near-infrared (NIR) light to interact with cells and tissues. The primary mechanism is absorption by cytochrome c oxidase in the mitochondrial electron transport chain, triggering increased ATP production, improved circulation, reduced oxidative stress, and calming of inflammatory signalling pathways. Blue light acts through distinct mechanisms and is particularly relevant for antimicrobial effects and certain inflammatory skin conditions. These cellular effects are foundational biological processes that underlie tissue repair, pain modulation, hormone-sensitive tissue health, skin regeneration, mood regulation, and immune function, which is why RLT has meaningful relevance across so many areas of women's health. At Fringe, we have developed a line of devices designed with women's health in mind: the Fringe Pelvic Wand for internal pelvic use; the Fringe Abdominal Belt and Regular Wrap for external abdominal and pelvic coverage; the Fringe Head Wrap for transcranial applications; the Fringe Face Mask for facial skin health; the Fringe Tiny Wrap for targeted body skin support; the Fringe Joint Wrap for joint-specific applications; the Fringe Extra Long Wrap for larger muscle group coverage; and the Fringe Full Body Mat for whole-body RLT. Top 10 Ways Red Light Therapy Can Support Women's Health 1. Menopause: Pelvic Comfort, Vaginal Health, and Bladder Support Declining estrogen during menopause drives a cascade of changes in pelvic tissues, collectively referred to as genitourinary syndrome of menopause (GSM). This includes thinning and drying of the vaginal walls, reduced elasticity and lubrication, increased tissue fragility, and a shift in vaginal pH that raises susceptibility to infection. These changes contribute to vaginal discomfort, pain with sex, and bladder symptoms including urgency and leakage. RLT supports pelvic tissue health through several mechanisms that are directly relevant to GSM. Red and NIR light stimulate collagen and elastin synthesis in mucosal and connective tissues, improving tissue thickness and resilience. They also improve microcirculation, which supports tissue hydration and the conditions needed for better lubrication. It has been suggested that transvaginal red and NIR light in vaginal atrophy and dryness may improve lubrication, reduce irritation, and support tissue health with consistent use. For urinary incontinence, RLT may support pelvic floor muscle performance and connective tissue integrity. Research has found improvements in stress urinary incontinence when light therapy was combined with pelvic floor exercises, and reduced leakage episodes, improved sexual quality, and pelvic floor muscle strength have been observed with combined light and vibration therapy. For dyspareunia (painful sex), red and NIR light address two of the primary contributing factors: tissue dryness and local inflammation. A recent review further supports the potential of transvaginal RLT to improve vaginal blood flow and tissue regeneration. Recommended products: Fringe Pelvic Wand, Fringe Abdominal Belt or Regular Wrap (external) 2. Mood Support: Easing the Emotional Weight of Hormonal Shifts Mood fluctuations are woven through virtually every stage of women's reproductive health. PMS, perimenopause, and the postpartum period all bring measurable neurobiological shifts in estrogen, progesterone, cortisol, and serotonin that affect emotional regulation, stress resilience, and sleep. These are not simply subjective experiences; they reflect physiological changes with real neurological underpinnings. Transcranial RLT, applied to the head, has emerged as a promising, non-pharmacologic approach for mood support. A recent integrative review in Lasers in Medical Science found that RLT showed improvements in brain activity, reduced anxiety, and antidepressant effects across multiple clinical studies. Similarly, a randomized controlled trial of wearable transcranial RLT for major depressive disorder and sleep further supports its mood-stabilizing and sleep-supportive effects. Since PMS is associated with measurable alterations in sleep architecture and circadian rhythm regulation, and because mood and sleep are tightly coupled, transcranial RLT during the premenstrual window, perimenopausal period, or postpartum recovery may help support both. Recommended products: Fringe Head Wrap 3. Skin Health: Aging, Conditions, and Post-Procedure Recovery Skin health is deeply connected to women's hormonal biology. Estrogen plays a central role in maintaining skin thickness, collagen content, and moisture, which means the hormonal shifts of perimenopause and menopause often bring visible and uncomfortable skin changes that may be supported by RLT. RLT may also be able to help support skin following aesthetic procedures and during wound healing. RLT has one of the strongest evidence bases in dermatology, with applications spanning everyday skin aging to chronic inflammatory conditions to aesthetic procedure recovery. A systematic review of LED therapy randomized controlled trials found that red and NIR light can improve wrinkles, skin texture, and elasticity with good tolerability. Clinical trials have further demonstrated significant reduction in periocular wrinkle volume and improvements in under-eye skin texture following consistent RLT. Across these applications, the core mechanisms are consistent: RLT supports mitochondrial energy in skin cells, improves local circulation, and stimulates fibroblasts to produce collagen and elastin. Blue light adds a distinct layer of benefit through its antimicrobial activity and influence on inflammatory skin immune pathways. Key skin health applications include: Skin Aging: Red and NIR light support collagen and elastin production, improve skin firmness and texture, and reduce the appearance of fine lines and wrinkles with consistent use. Eczema (atopic dermatitis): Red and NIR light support barrier repair and reduce inflammatory signalling, which may have relevance for eczema, although clinical trials are currently lacking. Blue light has shown clinical benefits for reducing eczema severity and itch. The National Eczema Association acknowledges the growing interest in LED devices, emphasizing conservative dosing and careful wavelength selection. Rosacea: Combined blue and red light therapy has shown improvements in redness and inflammatory lesions in controlled LED protocols. Red-only mode is often the best starting point for those prone to flushing. Psoriasis: In psoriasis, blue light influences immune activity in the skin and may slow excessive skin-cell proliferation, while red and NIR light address deeper inflammatory processes. Wound healing: Red and NIR light support angiogenesis, fibroblast activity, collagen remodelling, and epithelial repair. Blue light adds surface antimicrobial support. Post-procedure recovery (microneedling, chemical peels, laser, Botox, fillers): Red and NIR light introduced after the acute inflammatory phase has resolved can help calm lingering redness and support tissue repair. It is generally recommended to wait 24 to 72 hours after most procedures before applying RLT, though timing should always follow your provider's guidance. Recommended products: Fringe Face Mask; Fringe Tiny Wrap (body skin and wound support) 4. Menstrual Support: Pre-Menstrual Syndrome and Menstrual Cramps RLT may provide menstrual support to women, including both pre-menstrual syndrome (PMS) and dysmenorrhea (menstrual cramps). These are common experiences that affect the majority of women of reproductive age. Dysmenorrhea arises from uterine contractions driven by prostaglandin release and inflammatory signalling that creates cramping, radiating pelvic pain, and lower back ache. A 2025 systematic review of randomized controlled trials on light-based interventions for primary dysmenorrhea found reductions in pain intensity, decreased inflammatory signalling, and improved comfort with consistent abdominal light application. A randomized multicentre trial comparing RLT directly against the oral contraceptive pill for menstrual pain found that both achieved clinically meaningful reductions in pain, suggesting RLT is a viable non-pharmacologic option. Pre-menstrual syndrome (PMS) involves a broader constellation of symptoms: mood changes, bloating, sleep disruption, breast tenderness, and fatigue in the days before menstruation. Although no studies have examined PMS as a primary endpoint, adjacent research is relevant. PMS is associated with sleep and circadian rhythm changes, and transcranial RLT has been shown to improve sleep quality and stabilize the sleep-wake cycle. Mood-supportive effects of transcranial RLT, as discussed in section 2, are directly applicable to the luteal phase mood changes that characterize PMS. For abdominal bloating and early cramping that begins before the period, abdominal RLT may also offer comfort support. Recommended products: Fringe Regular Wrap or Abdominal Belt (abdominal and pelvic); Fringe Pelvic Wand (pelvic floor); Fringe Head Wrap (PMS mood and sleep) 5. Aches and Pains: Joints, Muscles, and Pelvic Discomfort Chronic pain affects women at higher rates than men across virtually every pain category. RLT addresses pain at a fundamental biological level, making it relevant whether the pain is joint, muscular, or pelvic in origin. For osteoarthritis, a clinical study published in the Annals of Rehabilitation Medicine (2024) showed meaningful pain reduction after RLT, and randomized trials have shown additive benefits when light therapy is paired with exercise. For muscle and myofascial pain, research suggests RLT may reduce delayed-onset muscle soreness, improve muscle recovery markers, and support faster return to performance, through enhanced mitochondrial ATP production and reduced inflammatory cascades. For pelvic pain, transvaginal RLT has shown meaningful clinical benefit. A study found that women with chronic pelvic pain experienced reduced symptoms and improved wellbeing following regular transvaginal RLT, with 64.5% of women meeting the threshold for clinically meaningful improvement. Combined with low-level vibration, transvaginal RLT may also help reduce pelvic floor hypertonicity, which is a common contributor to chronic pelvic pain. Recommended products: Pelvic pain: Fringe Pelvic Wand, Regular Wrap, or Abdominal Belt | Joints: Fringe Joint Wrap | Muscles: Fringe Regular Wrap, Extra Long Wrap, or Full Body Mat 6. Athletic Support and Recovery Women athletes face physiological considerations that are often underrepresented in sports science research, including the influence of the menstrual cycle on training response, recovery, and injury risk, and higher rates of certain injuries such as ACL tears and stress fractures compared to male athletes. RLT is one tool where the underlying mechanisms are directly relevant regardless of sex: the primary mechanism in athletic contexts is mitochondrial: RLT upregulates cytochrome c oxidase activity, enhancing ATP production and cellular energy efficiency. Both pre-exercise and post-exercise application have shown benefits. Pre-exercise light exposure, sometimes called muscular pre-conditioning, has been shown to reduce lactate accumulation, delay the onset of muscle fatigue, and increase the number of repetitions performed before exhaustion. Post-exercise, RLT may reduce markers of muscle damage including creatine kinase, support faster functional recovery, and reduce DOMS. A systematic review of randomized clinical trials found that RLT applied before exercise improved maximum voluntary contraction, oxygen consumption, time to exhaustion, and fatigue markers regardless of dose or wavelength variations. A 2025 comprehensive review further confirms RLT's role in skeletal muscle regeneration through fibroblast stimulation, collagen synthesis, and modulation of inflammatory and oxidative stress pathways, supporting its relevance for connective tissue repair and the higher rates of soft tissue injury seen in female athletes. Consistent use in the hours before or after training, rather than sporadically, allows cellular adaptations to compound over time. Full-body RLT extends these benefits systemically, supporting whole-body recovery in a single session. Recommended products: Fringe Joint Wrap, Fringe Regular Wrap, Fringe Extra Long Wrap, Fringe Full Body Mat 7. Cognitive Health: Focus, Clarity, and Brain Wellness Brain fog, cognitive fatigue, and difficulty concentrating are common complaints during perimenopause, the postpartum period, and in the context of chronic pain and poor sleep. These symptoms reflect real neurobiological changes: altered cerebral blood flow, shifts in neurotransmitter balance, and the effects of sleep disruption on prefrontal function. Transcranial RLT supports mitochondrial oxidative metabolism in neural tissue, improves regional cerebral blood flow, and modulates neuroinflammation. Controlled human studies have demonstrated improved attention, executive function, and memory performance following transcranial RLT, with neuroimaging evidence of increased regional cerebral blood flow and functional connectivity. Transcranial RLT shows promise across a wide range of neurological and psychological conditions, including cognitive impairment, depression, traumatic brain injury, and neurodegenerative disease, through these overlapping cellular mechanisms. For women navigating cognitive shifts at any stage, transcranial RLT offers a gentle, non-pharmacologic option for supporting mental clarity and brain resilience. Recommended products: Fringe Head Wrap 8. Fertility: Supporting Reproductive Wellness Fertility depends on a constellation of factors including egg quality, hormonal signalling, uterine receptivity, and pelvic blood flow. RLT does not treat infertility, but the cellular mechanisms it targets are directly relevant to reproductive physiology, particularly energy production in reproductive tissues, reduction of oxidative stress, and improvement of circulation. Eggs are among the most energy-demanding cells in the body, and the quality of their energy production is a key determinant of reproductive success. The human evidence, however, is limited to small uncontrolled case series. One case series followed women with unexplained infertility who received red and near infrared light over the lower abdomen and reported pregnancies among participants. An earlier clinic series similarly reported pregnancies when light was used through the pre-conception period. Neither included a control group, so these outcomes cannot be attributed to the light therapy itself. Many people align RLT use with their cycle, focusing on the follicular phase (approximately days 1 to 14). Those preparing for IVF or egg retrieval may consider beginning 2 to 3 months in advance, which aligns with the timeline of follicle development. Recommended products: Fringe Pelvic Wand (transvaginal), Fringe Abdominal Belt or Regular Wrap (external abdominal) 9. Pregnancy and Postpartum Support During pregnancy, RLT is generally considered safe when applied appropriately. Direct use over the abdomen is not recommended as a precaution. Common supportive applications include back, hip, and pelvic discomfort from postural changes and increased load; neck and shoulder tension; leg and foot heaviness and swelling; and mood and sleep support. Sessions on non-abdominal areas complement standard prenatal wellness practices. Postpartum recovery places significant demands on the body. For C-section recovery, research has demonstrated that red and NIR light can reduce postoperative pain, decrease inflammation, and improve tissue healing. For perineal wounds and episiotomy repair, research shows light exposure reduces pain and supports faster tissue recovery. Light therapy should only begin once wounds are fully closed and a clinician has confirmed it is safe. For postpartum pelvic floor recovery, transvaginal RLT may support tissue repair and complement pelvic floor physiotherapy once cleared for internal use. Research also suggests that red light therapy may offer benefits for breastfeeding-related discomfort. A review of studies looking at breastfeeding nipple trauma found that light therapy showed a trend toward reduced pain and improved. Another study observed reduced nipple pain and inflammation, as well as increased milk production when low-level light was used during breastfeeding. These findings suggest that red light therapy may be a gentle, non-invasive way to support comfort and continuation of breastfeeding. Recommended products: Fringe Pelvic Wand (with timing and clinician clearance); Fringe Abdominal Belt or Regular Wrap; Fringe Head Wrap (mood and sleep); Fringe Panel or Wrap (breastfeeding and musculoskeletal support during pregnancy) 10. Pelvic Diseases: Endometriosis, PCOS, Interstitial Cystitis, and Microbiome Support A number of chronic pelvic conditions disproportionately affect women and are often underdiagnosed and undertreated. RLT is not a treatment for any of these conditions, but may offer meaningful supportive benefits for pelvic comfort, tissue health, and the shared underlying mechanisms of inflammation and microvascular dysfunction. Endometriosis: Involves chronic inflammation, pelvic floor tension, and persistent pain that can radiate through the abdomen, pelvis, and lower back. A small 2022 study without a control group, presented at a gynecology conference, followed 48 women receiving transvaginal red and NIR light; over eight weeks, the share reporting moderate-to-severe pelvic pain fell from about 86% to 44%. Without a comparison group these results are preliminary, but external abdominal RLT may offer additional comfort support. PCOS: Preclinical research shows that red and NIR light may help normalize aspects of ovarian function and reduce inflammation associated with PCOS. Interstitial Cystitis / Bladder Pain Syndrome: A 2022 study found that red and NIR light applied to the suprapubic and pelvic-floor regions improved validated IC/BPS symptom indices including pain, urgency, and urinary frequency. Vaginal microbiome support: Emerging research suggests that RLT may help support a healthier vaginal environment by reducing inflammation, supporting beneficial bacterial activity, and modulating the immune response in vaginal tissues. Blue light adds a direct antimicrobial dimension, helping to discourage pathogenic organisms at the surface. Recommended products: Fringe Pelvic Wand; Fringe Abdominal Belt or Regular Wrap; Fringe Face Mask (PCOS acne) How to Use Red Light Therapy for Women's Health A wide range of Fringe devices can be used to support women’s health, including: Fringe Pelvic Wand — Transvaginal application with red, NIR, and blue light modes, plus vibration.

Fringe Joint Wrap — Joint-contoured red and NIR light with optional vibration. Applications: osteoarthritis, joint pain, athletic joint recovery. Fringe Regular Wrap / Extra Long Wrap — Large surface area red and NIR light. Applications: DOMS, myofascial pain, athletic recovery, back pain, pregnancy musculoskeletal support (away from abdomen). Fringe Full Body Mat — Whole-body red and NIR light. Applications: systemic recovery, broad musculoskeletal support, general wellness, athletic recovery. Light: Red and NIR light are the primary therapeutic wavelengths in RLT, and both are present in nearly all Fringe devices. Though their effects overlap, they differ in how deeply they penetrate tissue. Red light (typically 630 to 660 nm) is absorbed strongly in the skin and superficial tissues, making it particularly effective for collagen production, surface skin health, and tissue healing in areas close to the body's surface. NIR light (typically 810 to 850 nm) is less absorbed by surface tissue and penetrates more deeply, reaching muscles, joints, and deeper pelvic structures. This is why NIR is especially important for applications like athletic recovery, joint support, and transvaginal use. When used together, red and NIR light produce complementary and overlapping effects that benefit both superficial and deep tissues. Red light on its own (without NIR) may be preferred when heat sensitivity is a concern, for more delicate skin conditions like rosacea or melasma, when starting a new protocol and wanting a gentler introduction, or for conditions where surface-level effects are the primary goal and deeper penetration is less critical. Fringe devices vary in the number of light wavelengths and modes they offer. The Pelvic Wand, Face Mask, and Tiny Wrap each offer three modes, allowing you to choose between combined red and NIR light, blue light only, or red light only depending on your goals and sensitivity. The Head Wrap delivers three wavelengths of light, including red, NIR, and a longer NIR wavelength at 1050 nm that is unique to this device and chosen specifically to support brain health applications. The remaining devices, including the Regular Wrap, Extra Long Wrap, Joint Wrap, and Full Body Mat, deliver red and NIR light in a single combined mode with adjustable intensity. Intensity: All Fringe devices allow you to reduce light intensity to 50% by pressing the sun button. Reduced intensity is recommended when starting a new device or application, when using RLT on sensitive or reactive skin (rosacea, eczema flares, post-procedure recovery), when using the Pelvic Wand internally for the first time or after a break, and as a starting point during pregnancy or early postpartum. Full intensity is appropriate for most established uses once comfort is confirmed. Frequency: For most applications, 3 to 5 sessions per week is the standard recommendation. This frequency allows cells to recover and respond between sessions and aligns with research showing sustained benefits from consistent use. Daily use is safe but does not typically produce faster results than the recommended frequency. Some situations call for more frequent use: During active menstrual cramps, up to daily use is appropriate for abdominal and pelvic applications. In the 24 to 48 hours following intense training, daily use is appropriate for muscle and joint recovery. Blue light (Mode 2) should be limited to 2 to 3 times per week for active concerns, and 1 to 2 times per week for maintenance. Duration: Fringe devices have built-in timers that automatically end sessions at the recommended duration, so you do not need to time sessions manually. The Fringe Pelvic Wand, Tiny Wrap and Face mask have a 10-minute timer. Body wraps, the Head Wrap, and the Full Body Mat are set to 20 minutes. For conservative protocols (melasma, rosacea, post-procedure recovery, or first-time use of any device), starting with a 5-minute session and increasing gradually is advisable. Post-procedure use should always begin shorter and increase only if the skin remains calm. Conclusion Women's health is not a single issue but a lifelong journey through shifting biology, changing needs, and often inadequate support from conventional medicine. What makes RLT a compelling tool in this context is not that it addresses one condition, but that it operates at the level of cellular function, improving how cells produce energy, manage inflammation, and repair tissue. These are processes that matter across every stage of a woman's life, from the menstrual cycle to fertility to menopause and beyond. The research supporting RLT across these applications is growing, and while more dedicated clinical trials are still needed in some areas, the mechanistic foundation is well established, and the safety profile is excellent. Used consistently, as part of a broader approach to health, and alongside appropriate medical care, RLT offers women a non-invasive, evidence-informed tool that can be woven into daily life at home.

Learn moreHow Red Light Therapy Supports Abdominal and Pelvic Health
Why Abdominal and Pelvic Health Matter The abdomen is home to several of the body’s most important systems. Within this relatively small region are the digestive organs, reproductive organs, bladder, major immune tissues, and a large network of nerves that connect the gut to the brain. When these systems function well, they support digestion, metabolism, hormonal balance, immune function, and overall wellbeing. When they become disrupted, the effects can be widespread. Many common health concerns originate in, or strongly involve, the abdominal and pelvic region. Conditions such as digestive disorders, menstrual pain, bladder dysfunction, and pelvic pain affect millions of people and can significantly impact daily life. In many cases, these conditions involve complex interactions between inflammation, circulation, nerve signaling, and tissue health. Because of this complexity, researchers have increasingly explored non-invasive approaches that support the body’s natural repair and regulatory processes. One area of growing interest is Red Light Therapy (RLT), using red and near infrared light. These wavelengths of light interact with cells in ways that can influence energy production, inflammation, circulation, and tissue recovery. In recent years, scientists have begun studying how these effects may apply not only to skin and muscles, but also to deeper tissues within the abdomen and pelvis. This emerging research is opening the door to new ways of supporting digestive health, reproductive health, bladder function, and recovery from abdominal injury. How Red and Near Infrared Light Affect Abdominal Tissues Red and near infrared light therapy works by delivering specific wavelengths of light that interact with cells and tissues. When these wavelengths are absorbed by cellular structures, they can influence several biological processes involved in energy production, circulation, inflammation, and tissue repair. One of the most studied mechanisms involves the mitochondria, the structures within cells responsible for producing energy. Red and near infrared light are absorbed by molecules within the mitochondrial respiratory chain, which can improve cellular energy production and support normal metabolic function. Increased cellular energy can help tissues repair, recover, and function more efficiently. These wavelengths of light can also influence nitric oxide signaling in the body. Nitric oxide is a molecule that helps regulate blood flow and circulation. When circulation improves, tissues receive more oxygen and nutrients while metabolic waste products are cleared more efficiently. This effect may be particularly relevant in the abdomen and pelvis, where many conditions involve impaired circulation or chronic inflammation. Another important effect of red and near infrared light therapy is its ability to modulate inflammation. Numerous studies have shown that these wavelengths can influence inflammatory signaling pathways and support the body’s natural healing processes. Because many abdominal and pelvic conditions involve inflammatory mechanisms, researchers have increasingly explored light therapy as a potential supportive tool. Near infrared wavelengths are especially relevant for abdominal applications because they penetrate deeper into tissue than visible red light. This allows light energy to reach structures beneath the skin, including muscles, connective tissue, and deeper organs within the abdominal region. The Fringe Abdominal Belt uses three wavelengths that have been widely studied in light therapy research. The device delivers red light at 660 nm along with near infrared light at 850 nm and 1050 nm. Together, these wavelengths are designed to support both surface tissues and deeper structures within the abdomen and pelvis, and to have broad effects on cells and other structures in the abdomen (such as water). Introducing the Fringe Abdominal Belt The Fringe Abdominal Belt was designed to deliver red and near infrared light therapy directly to the abdominal and pelvic region in a simple, comfortable format. The device contains 135 LEDs that emit three wavelengths of therapeutic light: red light at 660 nm and near infrared light at 850 nm and 1050 nm. These wavelengths have been widely studied for their ability to support cellular energy production, circulation, tissue repair, and inflammation balance. While red light primarily interacts with tissues closer to the surface, near infrared light penetrates more deeply, allowing light energy to reach muscles, connective tissue, and other structures within the abdominal region. Here are some applications for each of the three wavelengths: 660 nm (Red Light): A very well-studied wavelength, 660nm is well absorbed in skin and superficial tissues, making this wavelength ideal for improving circulation and reducing inflammation near the skin’s surface. It also supports collagen production, accelerates wound healing, and promotes dermal regeneration. The 660nm wavelength also reduces oxidative stress and improves functionality of tissues. 850 nm (Near-Infrared Light): A well-studied NIR wavelength that penetrates more deeply into muscle and connective tissue, 850 nm is widely studied for its effects on mitochondrial ATP production, pain modulation, and nerve repair. Near-infrared light in this range activates cytochrome c oxidase and is frequently used in both sport recovery and neurological research. 1050nm (Near-Infrared Light): This longer wavelength near-infrared light has an effect on water, which may influence intracellular and extracellular water viscosity, potentially enhancing mitochondrial efficiency and protein dynamics. To make sessions convenient and accessible, the Abdominal Belt is fully portable and wireless. The device can be comfortably secured around the abdomen using an adjustable belt, allowing it to be worn while sitting, resting, or relaxing. This design makes it easy to position the device over areas such as the lower abdomen, pelvic region, bladder area, or digestive organs. In addition to light therapy, the Abdominal Belt also includes optional vibration therapy. Gentle vibration can support circulation and relaxation of abdominal muscles and may reduce pain and enhance comfort when using the device for pelvic or digestive concerns. Because the abdomen contains several interconnected systems including the digestive tract, reproductive organs, bladder, and large networks of nerves and immune tissues, supporting this region may have wide ranging effects on health. For this reason, researchers have begun exploring how RLT may help support a variety of abdominal and pelvic conditions. In the following sections, we will look at some of the most commonly studied and emerging applications of RLT for abdominal and pelvic health. Shop the Abdominal Belt Top Uses of Red Light Therapy for Abdominal and Pelvic Health The abdomen and pelvis contain several interconnected systems, including the digestive tract, reproductive organs, bladder, and large networks of nerves and immune tissues. Many common health concerns affecting this region involve inflammation, impaired circulation, muscle tension, and altered nerve signaling. Because red and near infrared light therapy can influence these biological processes, researchers have begun studying its potential role in supporting a variety of abdominal and pelvic conditions. The following sections highlight several areas where light therapy has been investigated or is emerging as a promising supportive approach. Pelvic pain. Chronic pelvic pain can arise from many causes, including muscle tension in the pelvic floor, inflammation of pelvic tissues, and altered nerve signaling. Red and near infrared light therapy has been studied as a non-invasive approach to help support tissue recovery and reduce pain in this region. Clinical studies investigating RLT for pelvic pain have reported meaningful reductions in pain severity and improvements in daily function, likely related to improved circulation, reduced inflammatory signaling, and better cellular energy production within affected tissues. While many of these studies used internal delivery methods, the underlying mechanisms they demonstrate may also be relevant to external light therapy applied over the lower abdomen and pelvic region. Dysmenorrhea (menstrual cramps). Dysmenorrhea, or painful menstrual cramps, affects a large proportion of menstruating women and is primarily driven by elevated prostaglandins that cause strong uterine contractions, inflammation, and reduced blood flow to uterine tissue. Research has begun exploring red and near infrared light therapy as a non-pharmacologic option for menstrual pain. A recent systematic review and meta-analysis of randomized controlled trials involving 645 participants found that light therapy significantly reduced menstrual pain compared with sham exposure after repeated use, with improvements typically observed over multiple menstrual cycles. The strongest evidence so far involves ~20-minute sessions once daily applied over the lower abdomen for several days around menstruation, repeated across multiple cycles. Endometriosis. Endometriosis is a chronic inflammatory condition in which tissue similar to the uterine lining grows outside the uterus, often leading to persistent pelvic pain, painful periods, and abdominal discomfort. Because inflammation, altered nerve signaling, and impaired circulation contribute to symptoms, researchers have begun exploring whether red and near infrared light therapy may help support comfort. Red light therapy is not a treatment or cure for endometriosis, and the human research so far is early and limited: in one small study without a control group, presented at a 2022 gynecology conference, women with endometriosis-related pelvic pain reported less pain after eight weeks of internally delivered light therapy. Because the study had no comparison group, it is not possible to know how much of that change came from the light itself rather than from other factors. These early findings are encouraging but preliminary. They point to light therapy applied over the lower abdomen and pelvic region as a gentle, non-invasive way to support comfort for people living with endometriosis, rather than as a way to treat the condition itself. Polycystic Ovary Syndrome (PCOS). Polycystic ovary syndrome is a complex condition involving hormonal imbalance, ovarian dysfunction, inflammation, and metabolic changes that can affect the reproductive system, skin, and energy metabolism. Red light therapy is not a treatment for PCOS, and it has not yet been studied in people with the condition. So far the evidence comes only from laboratory and animal research. These studies suggest that red and near infrared light may support healthier ovarian function by improving mitochondrial activity, reducing oxidative stress, and helping regulate inflammatory and endocrine signaling pathways. These effects have been associated with improvements in ovarian morphology, hormone balance, and cycle regulation in experimental models. Whether the same holds true in people has not yet been tested, but these early findings suggest that light therapy applied over the lower abdomen may be a gentle way to support pelvic tissue health and metabolic balance in people living with PCOS. Fertility support. Fertility depends on many factors, including ovarian health, egg quality, endometrial receptivity, and adequate blood flow to reproductive tissues. Red light therapy does not treat infertility, but the cellular processes it influences—mitochondrial energy production, oxidative stress, and circulation within ovarian and uterine tissues—are relevant to reproductive physiology. Laboratory and animal studies suggest that red light therapy may improve ovarian cell function, hormone balance, and follicle development while reducing inflammation and oxidative damage, though these are laboratory and animal findings that may not translate directly to people. In women, the published evidence is limited to small case series without control groups. One such case series followed women with unexplained infertility who received multiwavelength red and near infrared light over areas related to blood flow, including the area over the abdomen, and reported pregnancies among participants. Because there was no comparison group, it is not possible to attribute these outcomes to the light therapy itself. Because the human research in this area is still early and uncontrolled, light therapy is best thought of as a low-risk way to support reproductive tissue health and circulation during the preconception period, rather than as a fertility treatment. Overactive bladder. Overactive bladder (OAB) is characterized by urinary urgency, frequency, and sometimes urge incontinence, often caused by involuntary contractions of the bladder’s smooth muscle. A randomized, double-blind, placebo-controlled clinical trial evaluated a skin-adhesive light therapy device applied to the lower abdomen in people with OAB. After 12 weeks of sessions, participants using active light therapy experienced significantly greater reductions in daily urge urinary incontinence episodes and overall incontinence compared with the sham group, and more than two-thirds of participants achieved a ≥50% reduction in symptoms. The therapy was also well tolerated with no serious adverse events reported. These findings suggest that light therapy may help support bladder function by relaxing smooth muscle and improving pelvic circulation. Gut microbiome. The gut microbiome plays a central role in digestion, immune regulation, inflammation, and metabolic health. Emerging research suggests that red and near infrared light therapy applied to the abdomen may influence microbial balance in the gut. Experimental studies show that abdominal RLT can help preserve intestinal epithelial integrity and shift microbial populations toward beneficial bacteria that produce short-chain fatty acids such as butyrate, which support gut barrier health and reduce inflammation. Additional research has proposed the concept of “photobiomics,” in which red and near infrared light influence host metabolism, immune signaling, and microbial composition simultaneously, suggesting a potential pathway by which light therapy may support whole-body health through gut microbiome interactions. Gut–brain axis. The gut and brain communicate continuously through immune, metabolic, hormonal, and neural pathways collectively known as the gut–brain axis. Disruptions in gut microbial balance can contribute to systemic inflammation, altered neurotransmitter signaling, and neuroinflammation that affect mood, cognition, and neurological health. This may play a role in diseases such as Alzheimer’s and Parkinson’s. Emerging research suggests that red and near infrared light therapy applied to the abdomen may influence this axis by improving mitochondrial function, reducing inflammatory signaling, and modulating the gut microbiome. Preclinical and translational studies show that abdominal RLT can alter microbial composition, improve intestinal barrier function, and influence brain-related outcomes such as cognition, stress responses, and neuroinflammation. Experimental brain–gut RLT research further suggest that combined light exposure can restore stress-related cognitive changes while simultaneously modulating the gut microbiome and inflammatory signaling pathways. Gut diseases (IBS, IBD, Crohn’s disease, ulcerative colitis). Chronic gastrointestinal diseases such as irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), Crohn’s disease, and ulcerative colitis are characterized by intestinal inflammation, barrier dysfunction, altered immune signaling, and changes in the gut microbiome. Emerging research suggests that red and near infrared light therapy applied to the abdomen may help modulate several of these underlying mechanisms. Preclinical studies of ulcerative colitis models show that abdominal RLT can reduce inflammatory cytokines, decrease immune cell infiltration, and improve intestinal tissue structure and mucosal integrity. Additional experimental research suggests that light therapy may also influence gut microbiota diversity and immune pathways involved in inflammatory bowel disease progression. While human clinical research is still limited, these findings highlight a growing interest in light therapy as a supportive, non-invasive approach for intestinal health conditions. Abdominal wounds and surgical recovery. Red and near infrared light therapy have been widely studied for their ability to support tissue repair and wound healing. These wavelengths are known to influence key stages of healing by improving local circulation, supporting collagen production, and helping regulate inflammatory signaling. Research across a range of wound models shows that light exposure can enhance angiogenesis, fibroblast activity, and epithelial repair, creating conditions that support faster and more organized tissue recovery. Clinical studies have also explored postoperative applications, including recovery after abdominal surgery such as C-section incisions, where light therapy has been associated with reduced pain, improved tissue healing, and greater comfort during recovery once the incision is closed and cleared for light therapy by a medical provider. These findings suggest that targeted abdominal light therapy may be a supportive tool for people recovering from surgical wounds or other abdominal tissue injuries when used alongside appropriate medical care. Abdominal metabolic health and body composition. Abdominal fat is not just a storage tissue—it is metabolically active and closely linked to inflammation, insulin sensitivity, and hormonal signaling. Red and near-infrared light have been studied for their effects on cellular metabolism and adipose tissue biology. Studies suggest that light exposure can influence mitochondrial activity, lipid metabolism, and inflammatory pathways within adipocytes. In human studies using red light therapy applied to the waist and abdomen, participants have shown modest reductions in waist circumference and improvements in body contour compared with control groups. While these findings do not suggest that light therapy directly “melts fat,” they support the idea that improving local circulation, mitochondrial function, and metabolic signaling in abdominal tissues may influence body composition over time. These emerging findings highlight a potential role for abdominal light therapy as a supportive tool for metabolic health when combined with nutrition, movement, and other lifestyle strategies. How to Use the Fringe Abdominal Belt The Fringe Abdominal Belt is designed to deliver red and near-infrared light comfortably across the lower abdomen using a flexible, wearable design. The device contains 135 LEDs emitting 660 nm red light, 850 nm near-infrared light, and 1050 nm near-infrared light, allowing light to interact with both surface tissues and deeper abdominal structures. The belt also includes optional vibration therapy and a removable strap so the device can be worn comfortably during sessions. General Use: For most wellness goals, the Abdominal Belt can be used: • 3–5 sessions per week• 10–20 minutes per session The device includes a built-in timer for both 10-minute and 20-minute sessions, making it easy to follow a consistent routine. The light intensity can also be adjusted. At full intensity, the device delivers approximately 20–40 mW/cm² at the body surface. Users who prefer a more gentle session can reduce the intensity to 50%, which may be helpful for those who are sensitive to warmth or beginning light therapy for the first time. Positioning: Place the device directly over the lower abdomen, centered between the hips. The removable belt can be used to secure the device comfortably so the light panel stays in place during sessions. The belt can be worn while resting, sitting, or lying down. Using Vibration Therapy: The Abdominal Belt includes optional vibration therapy, which can be used alongside the light session. Gentle vibration may help relax abdominal muscles and improve local circulation, which some people find helpful when experiencing pelvic or abdominal discomfort. Vibration can be turned on or off depending on personal preference. Frequency Adjustments for Specific Needs: While most people benefit from 3–5 sessions per week, frequency can be adjusted depending on the goal. For example: • Menstrual cramps (dysmenorrhea): daily sessions during the painful portion of the menstrual cycle may be helpful. • General abdominal or pelvic wellness: 3–5 sessions per week is typically sufficient. • Sensitive users: begin with shorter sessions or reduced intensity and increase gradually as comfortable. As with all light therapy devices, consistency tends to produce the most noticeable results over time. Conclusion The abdomen is home to many interconnected systems that influence overall health, including the digestive organs, reproductive tissues, immune signaling pathways, and the gut microbiome. Because these systems are metabolically active and closely linked to inflammation, circulation, and cellular energy production, the abdominal region is an important target for supportive wellness therapies. Red and near-infrared light therapy have been studied across a wide range of biological processes relevant to abdominal health, including tissue repair, inflammation regulation, mitochondrial function, and microbial balance. Emerging research suggests that these mechanisms may influence diverse areas such as pelvic pain, menstrual discomfort, gut health, metabolic signaling, and postoperative tissue recovery. While the strength of evidence varies depending on the condition, the growing body of research highlights the broad biological activity of light within human tissues. The Fringe Abdominal Belt was designed to deliver these wavelengths comfortably and conveniently to the lower abdomen using 660 nm red light, 850 nm near-infrared light, and 1050 nm near-infrared light, combined with optional vibration therapy. With its wearable design, adjustable intensity, and built-in session timer, the belt allows users to integrate light therapy into regular wellness routines at home. Shop the Abdominal Belt As research into light therapy continues to expand, abdominal applications represent an exciting area of investigation. By supporting fundamental biological processes such as cellular energy production, circulation, and inflammation balance, targeted light therapy may offer a gentle and non-invasive way to support abdominal and pelvic wellness as part of a broader approach to health.
Learn moreIntroducing the Fringe Red Light Therapy Clinical Pad
Red light therapy (RLT) (also known as photobiomodulation) is increasingly used in both clinical and home settings to support tissue repair, reduce inflammation, and promote recovery. The therapy works by delivering specific wavelengths of red and near infrared light to the body, where they influence many cellular processes, most notably mitochondrial energy production. By increasing the availability of ATP, the primary energy currency of the cell, RLT can support healing, maintenance, and repair across many types of tissues. Over the past decade, wearable RLT devices have made this technology accessible outside of specialized clinics. Devices such as wraps and panels allow targeted light delivery to joints, muscles, and skin, making it possible to use light therapy at home as part of a regular wellness routine. At Fringe, our RLT products were designed to deliver wavelengths and light intensities that closely resemble the therapeutic portion of natural sunlight, which research suggests falls within an effective biological range. While wearable wraps remain one of the most versatile ways to apply RLT, some environments require equipment that can withstand more demanding conditions. Clinical settings, athletic training facilities, and veterinary environments often require devices that are durable, easy to disinfect, and resistant to sweat, oils, and hair. The Fringe Red Light Therapy Clinical Pad was designed with these environments in mind. Made from medical-grade silicone and powered by high-density LED light arrays delivering both red (660 nm) and near infrared (850 nm) wavelengths, the Clinical Pad provides the same therapeutic light exposure as our standard wraps while offering a surface that can be easily cleaned and disinfected between uses. What Makes the Clinical Pad Different from a Standard Wrap The Fringe Red Light Therapy Wrap remains one of the most versatile ways to apply red and near infrared light therapy. Its soft neoprene design makes it comfortable to wear and easy to position around many parts of the body, which makes it ideal for home use and for people who want a flexible wearable device. The Fringe Red Light Therapy Clinical Pad, however, was designed for situations where durability, hygiene, and ease of cleaning are especially important. Because of this design, the Clinical Pad may be particularly useful in situations such as: Clinical settings such as physiotherapy, chiropractic, and sports medicine clinics where devices need to be disinfected between patients. Athletic recovery environments, where sweat and skin oils can quickly accumulate on equipment. Veterinary and animal care, since silicone surfaces do not trap fur and can be easily cleaned after treating animals. Skin and dermatological applications, where hygienic surfaces are important when treating acne-prone skin or other conditions that benefit from careful cleaning between sessions. Both the Clinical Pad and the standard Fringe Wrap deliver the same therapeutic wavelengths and light intensity, meaning the biological effects of the light remain the same. The difference lies primarily in the material and the environments in which the device is most practical to use. Common Uses for the Fringe Red Light Therapy Clinical Pad Red and near infrared light therapy have been studied for a wide range of health applications. By supporting mitochondrial energy production and influencing cellular signaling pathways involved in inflammation and repair, these wavelengths can promote healing and recovery in many different tissues. Because the Clinical Pad can be easily positioned over many parts of the body, it can be used for many of the same applications as other Fringe red light therapy devices. Common uses include: Joint and muscle painRed light therapy has been studied for pain associated with joints, muscles, and connective tissue. Research suggests that red and near infrared light may help reduce inflammation and influence nerve signaling related to pain perception. Tendon and soft tissue injuriesLight therapy has been shown to support tissue repair by influencing cellular metabolism and collagen production, both of which play important roles in healing injured tissues such as tendons and muscle. Post-exercise recoveryAthletes often use red light therapy to support muscle recovery after training. Studies suggest it may help reduce muscle fatigue, decrease inflammation, and improve recovery between training sessions. Skin health and wound healingRed light therapy is widely used in dermatology and skin care because of its ability to support tissue repair and collagen production. It has been studied for applications including acne, scarring, and wound healing. General inflammation supportBecause inflammation is involved in many different health conditions, the anti-inflammatory effects of red and near infrared light may contribute to benefits across a wide range of tissues and systems. Like other Fringe red light therapy devices, the Clinical Pad delivers light at intensities designed to mimic the beneficial wavelengths of natural sunlight, allowing users to apply light therapy safely and conveniently to targeted areas of the body. How to Use the Fringe Red Light Therapy Clinical Pad The Fringe Red Light Therapy Clinical Pad is designed to make light therapy simple and easy to integrate into daily routines. Because the pad is flexible and lightweight, it can be placed directly on the skin over joints, muscles, or other target areas. Session duration The Clinical Pad includes built-in timers for both 10-minute and 20-minute sessions, which helps ensure consistent session times. These durations fall within the range commonly used in red light therapy research and help keep sessions within the therapeutic window. Light intensity The device allows the light intensity to be adjusted to either 100% or 50% power. Most users will use the full intensity setting, which delivers light in the approximate range of 20–40 mW/cm² at the skin. This intensity is similar to the therapeutic wavelengths of sunlight and falls within the range commonly used in light therapy studies. The 50% setting can be useful for people with more sensitive skin or when treating areas that may feel more sensitive to warmth. Session frequency For most applications, we recommend that RLT be used 3–5 times per week, with one session per day on the same area of the body. This is because the biological effects of light therapy can persist for 24–48 hours, meaning that repeated sessions on the same area within a short time frame may not provide additional benefit. It is also safe to use RLT daily, although doing it more often does not necessarily lead to faster results. Placement For best results, the pad should be placed directly against the skin over the area you wish to treat. Direct contact reduces light reflection and helps maximize the amount of light absorbed by the tissue. The flexible design allows the Clinical Pad to be used over many areas of the body, including: • joints such as the knee, shoulder, or elbow• large muscle groups such as the back or thighs• localized areas of pain or inflammation• skin areas requiring targeted light exposure Because the pad is wireless and portable, sessions can be done while sitting, resting, or lying down, making it easy to incorporate into daily routines. Cleaning the Clinical Pad One of the key advantages of the Fringe Red Light Therapy Clinical Pad is its medical-grade silicone surface, which allows the device to be easily cleaned and disinfected between uses. Unlike fabric-based devices, silicone does not absorb sweat, oils, lotions, or other substances that may come into contact with the surface during sessions. This makes the Clinical Pad well suited for environments where hygiene is important, including clinics, athletic facilities, and veterinary settings. To clean the Clinical Pad: • Wipe the silicone surface with a disinfecting wipe or cleaning solution that is safe for medical-grade silicone, such as alcohol-based disinfectant wipes commonly used in clinical settings.• Allow the surface to air dry before the next use.• Avoid soaking the device or allowing liquid to enter the charging port or control unit. Regular cleaning helps maintain a hygienic surface and allows the Clinical Pad to be used safely across multiple sessions. This easy cleaning process is one of the reasons the Clinical Pad is particularly useful in professional environments where equipment may be used repeatedly throughout the day. Conclusion Red light therapy has become an increasingly popular way to support tissue repair, reduce inflammation, and promote recovery across a wide range of applications. As interest in light therapy continues to grow, so does the need for devices that can be used in a variety of environments beyond the home. The Fringe Red Light Therapy Clinical Pad was designed to meet this need. By combining the same therapeutic red and near infrared light used in our standard wraps with a medical-grade silicone surface, the Clinical Pad offers a durable and hygienic option that can be easily cleaned between uses. Whether used in clinical practices, athletic recovery settings, veterinary care, or home environments where easy cleaning is important, the Clinical Pad provides a flexible and practical way to deliver targeted light therapy to the body.
Learn moreEndometriosis and Red Light Therapy: What the Evidence Shows
Can Red Light Therapy Help with Endometriosis? Some early research suggests red light therapy may help support pelvic comfort for people living with endometriosis, though the evidence base is still limited. Some people use it as a gentle, non-invasive complement to medical care, with the goal of supporting comfort and reducing sensitivity in the surrounding pelvic tissues. Red light therapy is not a treatment or cure for endometriosis. How Red Light Therapy May Help Endometriosis involves chronic inflammation, pelvic floor tension, irritation of the surrounding tissues, and often persistent pain that can radiate through the abdomen, pelvis, and lower back. These changes can make the pelvic region highly sensitive and can contribute to muscle guarding, pressure, and discomfort. Red and near infrared light have been shown in laboratory and clinical studies to reduce inflammation, support mitochondrial function, and increase blood flow through vasodilation. These mechanisms have been proposed as plausible reasons why light therapy might help with endometriosis-related pelvic discomfort. Some patients report that internal use feels relaxing to the pelvic floor, and that external application over the lower abdomen, pelvis, or lower back can be soothing. What the Research Actually Shows At Fringe, we are committed to being evidence informed and not exaggerating research findings. That means being honest about what is known and what is not. Here's where the evidence on red light therapy and endometriosis currently demonstrates: The Most Compelling Human Data The most directly relevant research is a 2022 conference abstract from Ajewole and colleagues at the University of Central Florida and Orlando VA, which followed 48 women with confirmed endometriosis who received transvaginal photobiomodulation over 8 weeks (Ajewole et al., Journal of Minimally Invasive Gynecology, 2022). The investigators reported a meaningful reduction in pain in this group. However, it is important to note that this is a conference abstract rather than a full peer-reviewed paper, and it used a single-arm before-after design with no control group, so it cannot distinguish light therapy effects from placebo or natural variation in pelvic pain over time. The study used a clinical laser device, though laser and LED light therapy generally produce comparable biological effects when wavelength and dosing are matched (Heiskanen & Hamblin, Photochemical & Photobiological Sciences, 2018). A few related studies have looked at transvaginal light therapy for chronic pelvic pain more broadly, in populations that included some endometriosis patients. A 2021 pilot study by Zipper and colleagues followed 13 women with chronic pelvic pain and reported reduced pain scores after nine treatments, though this too was a single-arm study with no placebo comparison (Zipper et al., 2021; PMC8617585). A larger observational cohort of 144 women with chronic pelvic pain has also been described in industry-affiliated reports, with most participants reporting pain improvement; however, the relevance to endometriosis specifically is uncertain because endometriosis was only one of several diagnoses included, and the evidence remains observational. (See: Contemporary OB/GYN report.) None of these studies were randomized or placebo-controlled. While each individual study has limitations, the pattern across them is encouraging. Several independent investigators, working with different patient populations and protocols, have observed that women with chronic pelvic pain — including those with endometriosis — tend to report less pain after transvaginal red light therapy. These patient-reported improvements, even in the absence of controlled comparisons, are meaningful to the people who experienced them. Larger and better-controlled trials are needed to confirm these findings, but the consistency of the early results is part of why this approach is gaining clinical attention. How It Works at the Cellular Level Although clinical research is limited, these observations align with what laboratory and animal research has shown about how red and near infrared light works in the body. Red light is absorbed by mitochondria and modulates inflammatory signaling — two mechanisms that are highly relevant to endometriosis, which is fundamentally an inflammatory condition. Animal and cell studies have shown that red light can reduce pro-inflammatory mediators, calm nociceptive (pain-sensing) nerve signaling, and lower levels of prostaglandins, which are the inflammatory lipids that drive uterine pain (Fu et al., Journal of Biophotonics, 2024). This research was conducted in a primary dysmenorrhea model, which is a related condition that shares key features with endometriosis: both involve cyclical pelvic pain, both involve elevated prostaglandins, and both involve the same inflammatory pathways in pelvic tissue. While dysmenorrhea and endometriosis are distinct diagnoses, the overlap in mechanism is part of why researchers are interested in red light therapy for endometriosis-related pain. The same anti-inflammatory and mitochondrial mechanisms have been demonstrated across many tissue types and pain conditions. Whether they translate into meaningful symptom relief for endometriosis specifically is what current and future human research is working to establish. The Honest Gaps in the Evidence It’s important to also acknowledge the gaps in the current evidence base. Large scale randomized controlled trials specifically designed for endometriosis have not yet been conducted. Also, most existing research has used laser devices rather than LED systems, though evidence suggests the therapeutic effects are comparable when dosing is properly managed. We also lack human data on whether light therapy can reduce the endometrial lesions themselves, rather than just managing symptoms. These gaps don't invalidate the existing evidence, but they do mean we should view red light therapy as a supportive tool rather than a primary treatment. We always recommend using light therapy for endometriosis with the guidance of a health care provider. How to Use Red Light Therapy for Endometriosis If you and your healthcare provider decide to try red light therapy for endometriosis-related pelvic discomfort, the Fringe Pelvic Wand may be used internally for ten minutes per session, three to five times per week. Internal use delivers light to the tissues of the pelvic region. Mode 1 (red + near infrared light) is the typical setting; Mode 3 (red only) may be preferred by people who are heat sensitive or who want a gentler session. Ensure the device is clean and follow the step-by-step instructions provided. External light may also be supportive. Apply the Fringe Wrap over the lower abdomen, pelvis, or lower back to help soothe irritation and support relaxation throughout the broader pelvic area. For more detailed guidance, you can read our comprehensive guide on Light Therapy and Vibration for Female Pelvic Health. Light therapy works best when combined with other supportive strategies, including pelvic floor physiotherapy, movement, and stress reduction techniques. Important Disclaimer This information is for general wellness and educational purposes only and does not constitute medical advice. Red light therapy is not a treatment or cure for endometriosis, and the available evidence is preliminary. Light therapy should never replace medical assessment, diagnosis, or treatment. Please always consult a healthcare provider familiar with endometriosis before starting a light therapy regimen, especially if you have complex symptoms, are pregnant or trying to conceive, are on hormonal treatments, or have concerns about how light therapy may interact with your current care plan.
Learn moreRed Light Therapy for Autism and ADHD
Autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) are two of the most common neurodevelopmental conditions in children and adolescents, and both frequently persist into adulthood. In the US, ADHD is estimated to affect approximately 7 million children, while ASD affects roughly 1 in 31 children, according to recent surveillance data. Although autism and ADHD are distinct diagnoses, they often overlap clinically. Many individuals with ASD also meet criteria for ADHD, and both conditions can involve challenges with attention, emotional regulation, sleep, and executive function. In fact, 50-70% of people with ASD also meet the criteria for ADHD. Beyond behavioral symptoms, research over the past two decades has identified recurring biological themes in both conditions. These findings do not suggest that ASD or ADHD are caused by a single mechanism. Both are multi-factorial and are influenced by complex genetic and environmental factors. However, patterns involving cellular energy metabolism, inflammation, gut–brain signaling, and circadian regulation have been repeatedly observed. These shared biological themes have opened the door to new supportive, non-pharmacologic strategies that target cellular function and regulatory balance. One area of emerging interest is photobiomodulation, commonly referred to as Red Light Therapy (RLT). RLT uses red and/or near-infrared light to influence biology and has been studied for decades in the context of wound healing, musculoskeletal health, and brain injury. More recently, early-stage research has begun exploring its potential role in supporting brain function in conditions such as ADHD and ASD. In this article, we will review: The biological overlap between ASD and ADHD How red and near-infrared light influences cellular function What current research shows (and does not show) in these conditions Practical considerations for safe and thoughtful use As always, our goal is not to position red light therapy as a cure or replacement for established therapies. Instead, we aim to present the science clearly, so families and clinicians can make informed decisions about whether it may serve as a complementary support strategy. What Is Red Light Therapy, and How Does It Work? Red light therapy refers to the use of specific wavelengths of red and near infrared light to influence biological function. Unlike ultraviolet light, red and near infrared wavelengths are non-ionizing and do not damage DNA at therapeutic intensities. Instead, they interact with cells through light sensitive molecules called chromophores. Most RLT devices use wavelengths in the red range, commonly around 630 to 660 nm, and the near infrared range, commonly around 800 to 850 nm, although some use longer wavelengths (over 1000nm) for broader effects. Red light tends to interact more strongly in superficial tissues, while near infrared light penetrates more deeply into soft tissue. For this reason, many devices combine both wavelengths. RLT devices that target brain health sometimes use only near infrared light, due to its deeper penetration, while others use both red and near-infrared for broader effects. The best supported biological mechanism involves the mitochondria, the energy producing structures inside cells. Red and near infrared light have been shown to influence mitochondrial function, including pathways related to cellular energy production and cellular redox signaling. When mitochondrial function is supported, cells may regulate inflammation, oxidative stress, and metabolic activity more effectively. In the brain, RLT has been studied for its effects on energy metabolism, inflammation, blood flow, and neural signaling. These mechanisms are part of why researchers have begun exploring red and near infrared light in brain health applications, including emerging work in ADHD and autism. What is the Shared Biology of ADHD and Autism? Although ADHD and ASD are distinct clinical diagnoses, research increasingly shows that they share overlapping biological patterns. These shared themes do not define every individual with either condition, and neither condition can be reduced to a single mechanism. However, certain pathways appear repeatedly in the scientific studies. Understanding these patterns helps explain why interventions that support cellular energy, inflammation regulation, gut function, and sleep may be relevant in both conditions. 1. Mitochondrial Dysfunction and Impaired Brain Energy Metabolism Mitochondria are responsible for producing cellular energy in the form of ATP. The brain is one of the most energy-demanding organs in the body, and even subtle shifts in energy metabolism can influence attention, emotional regulation, and executive function. In ADHD, studies have reported alterations in mitochondrial activity, increased oxidative stress, and changes in brain energy metabolism. In ASD, mitochondrial dysfunction has been observed in a significant subset of individuals, including abnormalities in electron transport chain activity, altered redox balance, and increased markers of oxidative stress. Not every person with ADHD or ASD has measurable mitochondrial dysfunction. However, cellular energy regulation appears to be a recurring theme in both conditions. 2. Increased Oxidative Stress and Neuroinflammation Oxidative stress refers to an imbalance between reactive oxygen species and antioxidant defenses. When persistent, it can influence cellular signaling, immune activity, and neural function. Elevated oxidative stress markers have been reported in both ADHD and ASD. In ASD in particular, neuroinflammation has been studied extensively. Post-mortem and imaging studies have identified activated microglia and altered inflammatory signaling in subsets of individuals with ASD. Neuroinflammation has also been observed in ADHD. Neuroinflammation does not imply infection, and it does not apply uniformly to all individuals with ASD or ADHD. Rather, it reflects altered immune signaling within the brain that may interact with mitochondrial function and oxidative stress pathways. 3. Altered Gut–Brain Axis & Microbiome The gut and brain communicate bidirectionally through neural, immune, and metabolic signaling pathways. This is often referred to as the gut–brain axis. In ADHD, research has identified differences in gut microbiome composition and diversity compared to neurotypical controls. In ASD, gastrointestinal symptoms are common, and multiple studies report microbiome differences, altered short-chain fatty acid profiles, and immune signaling shifts linked to gut health. The gut–brain axis is complex and not fully understood. However, microbiome composition can influence inflammation, neurotransmitter production, and metabolic signaling, all of which are relevant to attention and behavior. 4. Circadian Rhythm and Sleep Dysregulation Sleep disturbance is common in both ADHD and ASD. In ADHD, delayed sleep phase, difficulty with sleep onset, and evening alertness patterns are frequently reported. In ASD, sleep disturbance rates are high, with research showing differences in melatonin regulation and circadian rhythm signaling in some individuals. Circadian rhythm regulation is closely connected to mitochondrial function and inflammatory signaling. Disrupted sleep can amplify cognitive, emotional, and behavioral challenges in both conditions. How Does Red Light Therapy Intersect with These Pathways? This interconnected framework helps explain why researchers are exploring interventions that support cellular energy metabolism and regulatory balance across systems, rather than targeting only one symptom at a time. RLT has attracted interest in this context because of its documented effects on all four of the biological patterns that are commonly observed in both ADHD and ASD. 1. Mitochondrial and Cellular Energy Support The most widely studied mechanism of red and near-infrared light involves the mitochondria, and through the mitochondria, light also affects metabolism. In addition to regulating reactive oxygen species production, mitochondria also make the energy currency of the cell, called ATP. Specifically, red and near-infrared light stimulates cytochrome c oxidase, a mitochondrial enzyme that produces ATP. This increases ATP synthesis which provides more energy to brain cells. This appears to support more efficient cellular energy regulation under certain conditions. 2. Oxidative Stress Modulation Light is absorbed in cells by molecules called chromophores, many of which are found inside the mitochondria. Mitochondria are involved in regulating the production the reactive oxygen species that cause oxidative stress when present in high amounts. Light therapy has been shown to modulate oxidative stress and reactive oxygen species production. 3. Inflammation Reduction Red and NIRL have anti-inflammatory effects, and studies have found that light therapy affects levels of many molecules involved in inflammation, including reactive oxygen species, reactive nitrogen species, and prostaglandins. Red and near-infrared light therapy have specifically shown to reduce neuroinflammation. Some of these anti-inflammatory effects are linked to improved mitochondrial redox signaling. Others appear to involve immune cell modulation and nitric oxide signaling pathways. 4. Gut–Brain Axis & Microbiome Support Red and near-infrared light can be applied not only to the head but also to the abdomen. The intestinal lining is metabolically active and rich in mitochondria, and the gut microbiome interacts closely with immune and metabolic signaling systems. Animal and human research suggests that RLT may influence microbiome composition and gut inflammatory pathways. This axis represents an additional pathway through which light exposure to the body could exert indirect effects on the brain. 5. Circadian Rhythm and Sleep Regulation Red and near-infrared light interact with cellular energy systems and nitric oxide pathways, which may help support biological processes related to sleep quality. Research suggests that light exposure may improve sleep quality, especially when light is applied to the head. Importantly, unlike blue light exposure at night, red and near-infrared wavelengths do not suppress melatonin and are generally considered circadian-friendly. Improved sleep alone can meaningfully affect attention, mood regulation, and executive function which is highly relevant for people with ADHD and ASD. What Current Research Shows, and What It Does Not Research on red light therapy in autism and ADHD is still early, but a small number of human and animal studies have begun exploring its effects. Below is a brief overview of the most relevant studies to date. Several small clinical and preclinical studies have examined transcranial red and near-infrared light in autism: Diaz et al., 2026 - In this prospective open label case series, eight weeks of near-infrared RLT applied to the head of ASD subjects ages 6-38 resulted in improvements in cognition, emotional regulation, focus, and sleep quality. Fradkin et al., 2024 – In this randomized controlled trial, eight weeks of near-infrared RLT applied to the head in children 2-6 years resulted in statistically significant reductions in autism severity scores compared to sham treatment, with no moderate or severe adverse effects reported. Pallanti et al., 2022 – Six months of home-based near-infrared RLT applied to the head by 21 subjects with an average age of 9.1 years was associated with improvements in autism severity, rigidity, sleep quality, attention, and reduced parental stress. Ceranoglu et al., 2022 – Adults with high-functioning autism showed improvements in social responsiveness and executive function after eight weeks of treatment with near-infrared light applied to the head. Kim et al., 2022 – In a mouse model of autism, red/near-infrared light reduced neuroinflammation and improved social and cognitive behaviors. Research in ADHD is more limited, but studies have explored both human and animal models: Lai et al., 2025 – Adults with ADHD who received near-infrared light to the head for four weeks showed improvements in working memory and sustained attention performance, with mild and transient side effects. Huang et al., 2025 – In a rat model of ADHD, red/near-infrared light reduced hyperactivity and impulsivity behaviors and decreased markers of neuroinflammation in the prefrontal cortex. Taken together, these studies indicate that RLT with near-infrared light can influence biological systems relevant to both autism and ADHD, including mitochondrial function, inflammatory signaling, and neural connectivity, especially when applied to the head. Early human trials suggest potential improvements in attention, executive function, and autism severity scores, and animal studies consistently show reductions in neuroinflammation and behavioral improvements. Importantly, safety signals across studies have been reassuring, with few serious adverse effects reported in either pediatric or adult populations. At the same time, this field is still in its early stages. Most studies are small, and only one ASD study to date has used a randomized sham-controlled design. There are no large, multi-center clinical trials in either ADHD or autism, and long-term outcomes have not been well studied. Treatment protocols vary widely, making it difficult to compare results across studies. Red light therapy should not be viewed as a cure or a replacement for established therapies. Rather, current research suggests it may serve as a complementary approach that supports underlying biological systems in some individuals. Practical Ways to Use Red Light Therapy for ADHD and Autism If families or clinicians choose to explore RLT as a supportive approach in ADHD or ASD, it can be helpful to think about three areas discussed earlier in this article: brain function, gut–brain signaling, and circadian rhythm regulation. Common approaches include: We recommend a frequency of 3-5 times per week, although it is also safe to use RLT daily. Some people choose to alternate locations daily, applying light to the head one day and to the gut the following day. It is also possible to apply light to both the head and gut in the same day. Because some individuals with ASD have sensory sensitivities, it may be helpful to start gradually and ensure the device feels comfortable. Red light therapy should not replace established medical or behavioral care. However, emerging research suggests it may support biological systems relevant to ADHD and ASD, including cellular energy metabolism, inflammation, and circadian regulation. Conclusion Both ASD and ADHD involve complex interactions between brain biology, metabolism, sleep, and the gut–brain axis. Red and near-infrared light therapy is an emerging area of research that may help support some of these underlying systems. Although the science is still developing, early findings are encouraging. For families and clinicians interested in complementary approaches, RLT may offer a simple, non-invasive way to support overall neurological health alongside established care.
Learn moreTop Uses of Red, Near Infrared, and Blue Light for Family Health
Light therapy is increasingly used as a supportive tool for everyday health challenges that come up in family life. Using red, near infrared, and blue light, light therapy works at a cellular level to support processes like energy production, inflammation regulation, circulation, and nervous system balance. Because these processes are shared across all ages, light therapy can be adapted to a wide range of common needs, from skin irritation and minor injuries to immune support and digestive comfort. The Fringe Tiny Wrap was designed with this flexibility in mind. Its compact size and multiple light options make it easy to target specific areas of the body, allowing families to incorporate light therapy into daily routines in a simple, focused way. Below are some of the most common ways families incorporate red, near infrared, and blue light using the Fringe Tiny Wrap. 1. Aches, Pains, Bumps & Bruises Red and near-infrared light are commonly used to support circulation, cellular energy production, and inflammatory balance following minor injuries or physical strain. This can be helpful for sore muscles, tender spots, or bruises that linger after everyday activity. The Tiny Wrap’s small size makes it easy to place directly over the affected area, supporting recovery without restricting movement. 2. Skin Rashes & Inflammation Skin irritation and inflammation can appear anywhere on the body and often involve a mix of barrier disruption, inflammation, and microbial imbalance. Red and near-infrared light may support tissue repair and calm inflammatory responses, while blue light is known for its antimicrobial effects. The Tiny Wrap allows for targeted skin support in areas where larger devices aren’t practical. 3. Allergies & Seasonal Sensitivities Allergies are best understood as an over-reactive immune response rather than a weak one. Light therapy is sometimes used to support immune balance and tissue response during seasonal or environmental challenges. When symptoms are localized (such as sinus, skin, or upper-chest discomfort) the Tiny Wrap can be used to deliver focused light support as part of a broader wellness routine. 4. Asthma-Related Inflammation While light therapy is not a treatment for asthma, red and near-infrared light are sometimes discussed in the context of supporting inflammatory balance and relaxation in surrounding tissues. The Tiny Wrap’s compact design allows for gentle placement on areas like the upper chest or back, always alongside appropriate medical care and guidance. 5. Colds & Flus During periods of illness, the body’s energy and recovery demands increase. Red and near-infrared light are often used to support circulation, inflammation regulation, and cellular energy during rest and recovery. The Tiny Wrap makes it easy to apply light to areas such as the chest, back, or neck without adding strain during times when rest is a priority. 6. Growing Pains Periods of rapid growth are often accompanied by leg discomfort, muscle tightness, or nighttime aches. Light therapy is commonly used to support muscle relaxation, circulation, and comfort when applied locally to the legs or joints. The Tiny Wrap is especially well suited for this type of targeted, localized support. 7. Emotional Regulation & Stress The nervous system plays a central role in how the body responds to stress, sensory input, and emotional load. Light therapy is sometimes incorporated into calming routines to support nervous system balance and regulation. Because the Tiny Wrap is small and unobtrusive, it can be used gently and briefly as part of wind-down or regulation-focused routines. 8. Gut Health & Digestive Comfort Red and near infrared light applied externally to the abdomen are often discussed in the context of supporting digestive comfort, inflammatory balance, and gut–brain communication. The Tiny Wrap works well for focused abdominal placement, making it a practical option during periods of digestive stress or disruption. 9. Immune Support Immune function depends heavily on cellular energy availability and efficient inflammatory signaling. Light therapy is often used during times of increased immune demand to support these underlying processes. The Tiny Wrap’s portability and ease of placement make it convenient to incorporate into daily routines during cold season or periods of stress. 10. Targeted Skin Support Anywhere on the Body With blue light for surface-level skin concerns and red and near-infrared light for deeper tissue support, the Tiny Wrap is especially useful for localized skin needs beyond the face. Its precision placement allows families to support specific areas of concern wherever they appear, without committing to larger devices. Say Hello to the Tiny Wrap Conclusion At Fringe, we view light therapy as a foundational, at-home tool that supports the body on a cellular level. The Fringe Tiny Wrap reflects this philosophy by offering red, near infrared, and blue light in a small, adaptable format designed for precision placement. By making light therapy easy to use, easy to place, and easy to integrate into daily routines, the Tiny Wrap helps families support comfort, resilience, and everyday health in a simple, consistent way.

Learn moreFringe Kids Mighty Multivitamin: Our “Essentials” Supplement for Growing Bodies
We’re excited to introduce the Fringe Kids Mighty Multivitamin, a food-based vitamin and mineral supplement designed to support growing bodies. This formula was created to fill common nutritional gaps in children’s diets using primarily food derived ingredients rather than synthetic isolates. It provides foundational vitamins and minerals that support energy, learning, immune function, and overall development, without added sugar, artificial or “natural” flavors, dyes, or unnecessary additives. At Fringe, we believe children deserve supplements that are as thoughtful and intentional as the food we try to put on their plates. The Kids Mighty Multivitamin was designed with that philosophy in mind. Nutrient Depletion and Nutrient Gaps in Modern Childhood When we look at the context for children’s nutrition today, it helps to separate two related but distinct issues. One is the nutrient content of what children eat and drink. The other is whether what they consume provides enough of the vitamins and minerals their bodies need for growth, learning, immunity, and everyday function. Many aspects of our food supply have shifted over the past several decades in ways that can affect both vitamin and mineral content. Studies of nutrient density in fruits, vegetables, and staple crops have documented declines in both minerals and vitamins compared with historical baselines, reflecting changes in agricultural practices, plant breeding, soil quality, and global food systems. These analyses have found measurable drops in nutrients such as calcium, magnesium, iron, vitamin A, and vitamin C in a range of produce over time, suggesting that even when children eat foods that appear wholesome, the absolute nutrient content per serving may be lower than it once was. Magnesium has been especially affected, with losses of up to 80-90% in some foods over the last century. In addition to agricultural influences, naturally occurring minerals in water such as calcium, magnesium, sodium, chloride, and potassium have traditionally contributed to daily intake for many individuals. Depending on local water composition, these minerals can account for meaningful portions of recommended intake values, particularly for calcium and magnesium. However, modern filtration practices remove these minerals from water in the process of ridding them of contaminants, which can reduce overall nutrient intake. Collectively, these patterns in food and water help explain why certain micronutrients are consistently identified as shortfall nutrients in U.S. dietary surveys. National data from the National Health and Nutrition Examination Survey (NHANES) show that many U.S. children do not meet recommended intakes for multiple vitamins and minerals when intake is assessed from foods and beverages alone. In toddlers and young children, large proportions fall below the Estimated Average Requirement (EAR) for vitamin D and vitamin E, while most do not reach Adequate Intake (AI) levels for potassium and choline. As children move into the school-age years, nutrient gaps widen, with continued inadequacy in vitamin D, vitamin E, calcium, choline, and potassium. By adolescence, NHANES data show widespread shortfalls across a broad range of nutrients, including vitamin D, vitamin E, calcium, magnesium, folate, iron, and potassium, with particularly high rates of inadequacy among adolescent females. These patterns occur even when overall calorie intake is sufficient, indicating that nutrient gaps reflect dietary quality and food patterns rather than simple undereating. These gaps are not simply a “picky eater” issue. They reflect modern dietary patterns that can provide adequate calories while still falling short on micronutrients. One major factor is the high proportion of daily calories coming from ultra processed foods among U.S. youth. Ultra processed food intake increased among U.S. youths from 1999 to 2018, with recent CDC NHANES-based surveillance data reporting that youth ages 1 to 18 obtain about 62 percent of calories from ultra processed foods. When a large share of the diet is coming from foods designed for convenience, shelf stability, and hyper palatability, there is less room for consistent intake of nutrient dense staples like vegetables, legumes, seafood, and mineral rich whole foods. The take-home point is that nutrient gaps in U.S. children are measurable, consistent, and widespread, affecting both vitamins and minerals. These gaps matter because many micronutrients support foundational biological processes, from energy metabolism to immune signaling to neurologic development. When intake falls short of recommended levels year after year, it contributes to what nutrition scientists describe as chronic insufficient intake, or “micronutrient gaps,” rather than acute clinical deficiency. Addressing these gaps requires thoughtful support for nutrients that are hard to obtain consistently from modern diets alone. This is the context in which a carefully designed children’s multivitamin can serve as a nutritional backstop for growing bodies. Why These Nutrients Matter During Childhood Identifying nutrient gaps is only part of the picture. It is also important to understand why adequate intake matters during childhood, when growth and development place higher and more dynamic demands on the body. Vitamins and minerals support fundamental biological processes, and when intake consistently falls below age-appropriate needs, those processes can be affected even in the absence of overt deficiency disease. 1) Growth and physical developmentNormal growth during childhood depends on the coordinated activity of multiple micronutrients that support cell division, tissue development, and skeletal maturation. Zinc plays a role in growth and bone formation, calcium and vitamin D are central to bone mineralization and skeletal integrity, magnesium supports bone structure and energy metabolism, and iron contributes to oxygen delivery and physical capacity during growth. Research has shown that inadequate intake or status of these nutrients can be associated with impaired growth patterns, reduced bone mineral density, or suboptimal physical development, particularly during periods of rapid growth. While severe deficiency states are uncommon in high-income countries, habitual intakes that fall below recommended levels may still limit optimal support for these foundational processes over time. 2) Brain development, learning, and cognitionBrain development during childhood relies on a steady supply of micronutrients that support neuronal growth, myelination, neurotransmitter synthesis, and energy metabolism in the nervous system. Iron is required for oxygen delivery and normal neurodevelopment, and inadequate iron status in childhood has been associated with alterations in cognitive development and attention. Iodine is essential for thyroid hormone production, which plays a central role in brain development and cognitive function, particularly during early life. Choline contributes to cell membrane structure and neurotransmitter synthesis and is involved in pathways related to memory and learning, yet intake is consistently low in children. Several B vitamins, including folate, vitamin B6, and vitamin B12, support one-carbon metabolism and neurotransmitter production, while magnesium participates in neuronal signaling and energy metabolism. When habitual intake of these nutrients falls below recommended levels, it may limit optimal support for the developing brain, especially during periods of rapid learning and cognitive growth. 3) Immune function and energy metabolismThe immune system and the body’s ability to produce and regulate energy are closely tied to micronutrient status during childhood. Vitamin A supports the integrity of epithelial barriers and immune cell differentiation, while vitamin D plays a regulatory role in both innate and adaptive immune responses. Vitamin C and zinc contribute to immune cell function and antioxidant defense, and inadequate intakes have been associated with altered immune responsiveness. At the same time, nutrients such as magnesium, iron, and B vitamins are involved in mitochondrial function and enzymatic reactions that govern energy production and cellular metabolism. When intake of these nutrients is consistently low, children may have less metabolic flexibility to meet the demands of growth, physical activity, and immune challenges, even if overt illness or deficiency is not present. Taken together, this research highlights that vitamins and minerals support a wide range of foundational processes during childhood, from physical growth to brain development to immune and energy regulation. When intake consistently falls short of age-appropriate needs, these systems may be supported less efficiently over time, even in the absence of overt deficiency. This is the context in which maintaining adequate, consistent micronutrient intake becomes relevant to everyday childhood health. Why We Consider a Multivitamin “Essential” for Kids (Even for Healthy Eaters) We consider a children’s multivitamin essential because meeting nutritional needs consistently over time is challenging, even in families that prioritize healthy food. As we’ve just seen, nutrition needs are often unmet due to nutrient gaps, water and mineral depletion of vitamins and minerals, and high consumption of ultra processed food. In addition, childhood is a period of rapid growth and development, and the demand for vitamins and minerals shifts alongside physical growth, brain development, immune maturation, and learning. At the same time, food intake is rarely steady, varying with changes in appetite, preferences, and habits. Even with a well-planned diet, children do not eat the same foods in the same amounts every day, and nutritional adequacy is determined by patterns over weeks and months rather than by individual meals. Some nutrients need to be consumed regularly to maintain adequate levels, and repeated shortfalls, even small ones, can accumulate during periods of growth. This reality is not a reflection of poor parenting or poor dietary choices, but a natural consequence of childhood and the modern food environment. We believe that a daily kid’s multivitamin with minerals is “essential” because it provides a steady nutritional baseline when intake is uneven, inadequate, or unpredictable. While this support can be provided by synthetically sourced nutrients, food-based vitamins and minerals are delivered in amounts and combinations that more closely resemble how nutrients occur in the diet, which allows them to support physiology in a way that is gentler and more consistent with nature. In this context, a food-based multivitamin is better suited to act as an everyday nutritional backstop, working alongside real food rather than attempting to replace it or override normal dietary patterns. Fringe Kids Mighty Multivitamin: What’s In It? When we formulate supplements for children, we start by asking a simple question: what does the body actually need on a daily basis, and how can we provide that support in the most appropriate way? The Kids Mighty Multivitamin was built using a “nature first” philosophy with that question in mind, using a combination of whole-food nutrients, targeted additions, and carefully chosen supporting ingredients to create a formula that is both effective and gentle. Meet the Mighty Good Multivitamin! 1. The Foundation: A Whole-Food Nutrient Blend At the core of the Kids Mighty Multivitamin is a 21-nutrient, organically grown fruit and vegetable blend, which provides a broad spectrum of vitamins, minerals, and phytonutrients in a form that closely resembles how nutrients occur in food. This blend includes broccoli, spinach, kale, pumpkin, sweet potato, sunflower seed, cranberry, chlorella, maitake mushroom, and shiitake mushroom. Because this multivitamin is built on a food-based foundation, some of the vitamin forms may look different from what people are used to seeing in standalone supplements. The vitamin D present in the blend is vitamin D2, and the vitamin K is vitamin K1, which reflect the forms naturally found in plant foods. Vitamin D3 and vitamin K2 can also be derived from natural, vegan sources and are often used in targeted supplements for specific goals (such as our Fringe Vitamin DK supplement). In this formula, however, the intent is different. As an everyday, food-based multivitamin, the goal is to provide gentle, consistent nutritional support using nutrient forms that align with how vitamins are typically consumed in the diet, while still supporting normal absorption and biological function. By building our multivitamin around real foods rather than isolated synthetic vitamins, we aim to provide nutritional support that works alongside the body’s natural processes, rather than overwhelming them with high doses of single compounds. 2. What We Added, and Why While a food-based foundation can provide a broad range of vitamins and minerals, it also reflects the realities of the modern food system. Declines in soil mineral content, loss of naturally occurring minerals from filtered water, and inconsistent intake of nutrient-dense foods mean that some nutrients are simply harder for children to obtain in adequate amounts, even with a diet built around whole foods. For that reason, relying on a fruit and vegetable blend alone is not always sufficient to meet foundational needs. Based on intake data and these practical constraints, we made the intentional decision to add three nutrients that consistently emerge as shortfall nutrients in children. Magnesium was added because it plays a central role in energy metabolism, muscle and nerve function, and overall cellular health, and because both dietary intake and environmental availability have declined over time. Calcium, sourced from calcified algae, was added to support bone development and growth during childhood, using a naturally derived form that fits within a food-based framework. Choline is the only synthetic ingredient in the formula, and its inclusion was deliberate. Choline is essential for brain development, cell membrane structure, and neurotransmitter synthesis, yet intake is consistently low in children. Because choline is not present in meaningful amounts in most plant foods or food-based blends, we chose to include it as a standalone nutrient to ensure adequate support during key developmental years. 3. The Supportive Players Beyond the primary nutrients, the Kids Mighty Multivitamin includes a small number of supportive ingredients that were chosen with equal care. Chicory root inulin provides a gentle source of prebiotic fiber to support gut health. Organic freeze-dried raspberry and strawberry fruit powders contribute natural flavor and color without added sugar or artificial ingredients. Organic rice hulls serve a functional role in the powder without introducing unnecessary additives. For sweetness, we use thaumatin, a protein-derived sweetener sourced from the katempfe fruit. Thaumatin is intensely sweet, which allows us to use it in extremely small amounts, contributing virtually no calories and having no impact on blood sugar. Unlike many other sweeteners used in children’s supplements, thaumatin does not rely on sugar alcohols, stevia, or artificial sweeteners, making it a cleaner and better-tolerated option. Malic acid, which occurs naturally in fruits, is included to support flavor and palatability while fitting seamlessly into a food-based formulation. We’ve taste tested our Mighty Multivitamin with kids and they’ve loved it! Every ingredient in the Kids Mighty Multivitamin serves a purpose. There are no dyes, added sugars, “natural” or artificial flavors, or unnecessary fillers. The goal is not to make a supplement that looks or tastes like candy, but one that supports children’s health thoughtfully and responsibly, using ingredients that align with how their bodies are meant to be nourished. How to Use It The Kids Mighty Multivitamin is designed to provide meaningful nutritional support without overwhelming the system or attempting to replace food. Across age groups, the recommended servings deliver supportive amounts of most vitamins and minerals, generally falling in at 30-70% of daily requirements. This is intentional. The goal is to leave room for nutrients to come from the diet while providing a steady baseline that helps cover common gaps when intake is uneven or unpredictable. At times when nutritional intake is clearly inadequate, the recommended daily dose can be increased by 1/3, 1/2, or – on rare occasions – even a full scoop. For many nutrients, daily intakes in the range of moderate support rather than full replacement are both appropriate and desirable, particularly when a multivitamin is used long term. Calcium is a good example. The amount included in Kids Mighty is not intended to meet daily calcium needs on its own, but rather to mirror the type of calcium intake that typically accompanies meals. Most children obtain calcium primarily from food, and this formula is designed to complement that pattern rather than override it. Vitamin D deserves special mention. While Kids Mighty provides a food-based source of vitamin D, many children will still require additional vitamin D supplementation depending on factors such as sun exposure, latitude, season, skin coverage, and time spent outdoors. When vitamin D is supplemented separately, vitamin K should also be included to support proper calcium handling and bone health. This is why we offer a dedicated vitamin D and K supplement for families who need targeted support beyond what a daily multivitamin can reasonably provide. To use, simply mix the recommended serving into water, a beverage, or food of choice and stir well. Ages 2 to 3: ⅓ scoop daily Ages 4 to 8: ½ scoop daily Ages 9 and up: 1 scoop daily Kids Mighty is not intended for children under 2 years of age. As with all Fringe supplements, this product is meant to work alongside real food, not replace it. Think of it as a quiet, consistent layer of support that fits into daily life and adapts to the realities of growing bodies, changing appetites, and modern nutrition. Kids Mighty Multivitamin & Our Small Scoops Mission The Kids Mighty Multivitamin was created as a reflection of our Small Scoops Mission. We believe that supporting children’s health means being thoughtful and restrained, not aggressive or excessive. Supplements should work alongside food, respect the body’s natural processes, and provide meaningful support without unnecessary ingredients or high doses. Every aspect of our Kids Mighty Multivitamin was designed with this philosophy in mind. A food-based foundation, targeted additions where modern diets often fall short, and carefully chosen supporting ingredients, all combined in amounts that are intended to complement, not replace, real food. Just as important are the ingredients we chose to leave out, including added sugars, artificial and “natural” flavors, dyes, and unnecessary fillers. As parents, we take seriously the responsibility of formulating for children. The Small Scoops Mission is about stewardship, transparency, and long-term thinking, and Kids Mighty is our way of putting that into practice in a form that fits naturally into daily life.

Learn moreRed Light Therapy for Family Health: Using Light Therapy to Support the Whole Household
Why “Family Health” Is the Right Lens for Light Therapy Rather than targeting specific conditions, light therapy may be used to support core biological processes that are shared across all ages within a family. From young children to preteens, teens, and parents, light therapy works a cellular level to influence how efficiently cells produce energy, how tissues regulate inflammation, how blood and oxygen are delivered, and how the nervous system responds to stress and recovery. These same processes underpin immune function, injury healing, emotional regulation, and overall resilience, which is why light therapy naturally lends itself to family health. Light therapy using red and near-infrared light, with targeted use of blue light in certain applications, is best understood as a supportive wellness tool that helps the body function more efficiently and recover more effectively through common, everyday challenges families face. For parents, this approach has clear advantages: light therapy is non-invasive, does not rely on medications, can be adapted across different ages and sensitivities, and fits easily into daily routines at home. In this blog, we’ll explore how families may use light therapy to support key areas of health, including pain and injuries, skin health, brain health, gut health, immune support, and allergies. Within each area, we’ll look at practical examples relevant to different family members, such as acne in teens, stress in parents, and growing pains in younger children. Throughout, we’ll focus on the underlying biology, what the research suggests, and how light therapy can be used safely and practically in a family setting. How Light Therapy Works at a Cellular Level Light therapy (also known as photobiomodulation) uses specific wavelengths of light (most commonly red and near-infrared, with targeted use of blue light) to influence fundamental biological processes in the body. Red and near-infrared wavelengths are absorbed primarily by mitochondrial components within cells, where they improve the efficiency of ATP production, the cell’s primary energy source. By supporting cellular energy availability, these wavelengths help fuel processes such as tissue repair, inflammation regulation, circulation, and nervous system balance. This shared cellular mechanism helps explain why red and near-infrared light are used across a wide range of family health applications, from injury recovery and immune support to brain and gut health. Blue light works through a different, more surface-level set of mechanisms. Rather than targeting mitochondrial energy production, blue wavelengths interact primarily with chromophores in the skin and superficial tissues, including bacterial porphyrins and immune-related signaling pathways. This makes blue light particularly useful for applications such as acne, blemish control, and certain inflammatory skin conditions that are common in children and teens. When used at appropriate intensities and durations, blue light may support skin health without penetrating deeply or disrupting underlying tissue. Together, these complementary mechanisms explain why “light therapy” is not a single effect, but a flexible tool that may be adapted to different tissues, ages, and health needs within a family. Safety and Practical Use Across the Family Light therapy has a strong safety profile and has been studied across thousands of research studies, including widespread use in dermatology, rehabilitation, and wellness settings. When delivered using LED devices at appropriate intensities, red, near infrared, and blue light are considered non-invasive and non-thermal, meaning they may support biological processes without damaging tissue or disrupting normal physiology. This makes light therapy suitable for repeated use within families when applied thoughtfully and with age-appropriate guidance. That said, responsible use still matters, particularly in households with children. The most important principle is “low and slow.” Children, preteens, teens, and parents may respond differently to light exposure, and more is not better. Starting with shorter sessions, moderate frequency, and allowing time between treatments helps keep exposure within a beneficial range. Light therapy should always be supervised when used by children, especially young children, and should be paused if irritation, discomfort, or unusual symptoms occur. Direct eye exposure should be avoided, and treatments should never be done while sleeping. Finally, light therapy is best viewed as a supportive tool, not a replacement for medical care. It does not diagnose or treat disease, and families should continue to follow medical guidance for infections, injuries, neurological concerns, or chronic conditions. When used appropriately, light therapy may complement healthy family routines by supporting the cellular foundations of recovery, resilience, and day-to-day wellbeing. How Families Use Light Therapy to Support Everyday Health Within a family, health needs vary by age and stage, but the underlying biology often overlaps. Inflammation, tissue repair, nervous system regulation, and cellular energy production are relevant whether you’re managing a scraped knee, recovering from a sports injury, dealing with chronic tension, or simply trying to keep up with daily demands. Because light therapy works by supporting these shared physiological processes, it may be adapted to different family members and situations without becoming condition specific. In the sections below, we’ll explore several core areas where families commonly use light therapy, along with practical examples that reflect real-life needs across childhood, adolescence, and adulthood. Pain & Injuries Pain and minor injuries are a routine part of family life. Here, red and near infrared light are key players. These wavelengths of light may support cellular energy production, circulation, and inflammatory balance, processes that are central to tissue repair and muscle recovery. By improving the cellular environment, light therapy may help muscles relax, reduce lingering soreness, and support the body’s natural healing response following minor injuries or physical stress. How this can look across a family: Young children: bumps, bruises, leg discomfort, and growing pains, particularly at night during periods of rapid growth. Preteens and teens: sports-related strains, overuse injuries, and muscle soreness during growth spurts or busy training schedules. Parents: recurring aches, joint stiffness, or muscle tension related to work, stress, posture, or previous injuries. When used thoughtfully, light therapy may be a simple addition to family routines that support comfort and recovery after everyday physical strain. It’s often used during periods of soreness, growth-related discomfort, or minor injuries when the body needs extra support to recover. Skin Health Skin health concerns often change across childhood, adolescence, and adulthood, but many share the same underlying drivers, including inflammation, impaired barrier function, microbial imbalance, and slowed cellular repair. Light therapy may support skin health by influencing these processes at a cellular level, using red, near infrared, and blue light in complementary ways. Red and near-infrared light may increase cellular energy production, circulation, collagen synthesis, and inflammatory balance within the skin, while blue light acts more superficially and is best known for its antimicrobial effects, particularly against acne-associated bacteria. When used appropriately, these wavelengths work together to make light therapy a flexible, supportive option for skin health across a family. How this can look across a family: Young children: rashes, irritated skin, slow-healing scrapes, or eczema flare-ups where red, near-infrared, and blue light can help reduce inflammation, support tissue healing and repair, and eliminate troublesome infections. Preteens and teens: acne and inflammatory breakouts, where blue light may support bacterial balance while red and near-infrared light help calm inflammation and support healing. Parents: stress-related skin changes, rosacea-prone or reactive skin, and early signs of skin aging, where red and near-infrared (and occasionally blue) light may be used to support barrier function, circulation, and overall skin resilience. As part of a consistent routine, light therapy may help support healthier skin responses across different ages and stages within a family. By working with the skin’s natural repair and balance mechanisms, it offers a gentle, at-home approach to ongoing skin care. Brain Health Brain health plays a central role in how children learn, how teens regulate emotions and attention, and how parents manage stress, mood, and mental clarity. Across these stages, common underlying factors, such as brain energy demand, neuroinflammation, and nervous system regulation, shape how the brain responds to everyday challenges. Light therapy, including red and (especially) near-infrared light, may support these foundational processes by influencing cellular energy production, blood flow, and inflammatory balance in the brain. How this can look across a family: Young children: focus, mood, ADHD- and autism-related regulation, and sleep-related challenges, where light therapy is sometimes used to support nervous system calm and resilience. Preteens and teens: focus, mood, ADHD- and autism-related regulation, as well as recovery following sports-related head impacts or concussions, where supporting brain energy and recovery is especially important. Parents: stress, low mood, mental fatigue, and cognitive load, particularly during busy or high-demand periods of family life. When used thoughtfully, light therapy may be a simple addition to family routines that support brain resilience and regulation across different ages and stages. Families often turn to it during periods of high cognitive demand, emotional stress, or recovery when the brain may need extra support. Gut Health Gut health plays an important role in digestion, immune function, and communication with the brain, often referred to as the gut–brain axis. In family life, gut-related challenges can show up as abdominal discomfort, irregular digestion, food sensitivities, or changes in mood and behavior. Light therapy, primarily using red and near-infrared light applied externally to the abdomen, may support gut health by influencing cellular energy production, inflammation regulation, circulation, and communication between gut tissues and the nervous system. How this can look across a family: Young children: digestive discomfort, irregular bowel habits, or gut-related immune sensitivities, where supporting gut balance may also influence overall comfort and behavior. Preteens and teens: stress-related digestive issues, food sensitivities, or gut–brain interactions that can affect mood, focus, and energy. Parents: bloating, sluggish digestion, stress-related gut symptoms, or ongoing gut inflammation associated with busy schedules and chronic stress. In family settings, light therapy may be used to support gut balance and resilience during periods of digestive stress or disruption. It’s typically incorporated alongside nutrition, hydration, sleep, and stress management as part of a broader approach to gut health. Immune Support The immune system plays a constant role in family health, helping the body respond to infections, heal injuries, and maintain balance with the environment. In children, this often shows up as frequent colds or slow recovery; in teens, immune stress may intersect with growth, sleep, and training demands; and in parents, chronic stress can place ongoing strain on immune resilience. Light therapy may be used to support immune health by influencing cellular energy production, inflammation regulation, and circulation, all of which help immune cells do their work efficiently. How this can look across a family: Young children: frequent colds, prolonged recovery, or immune stress during school and daycare years. Preteens and teens: immune strain during periods of rapid growth, heavy activity, or sleep disruption. Parents: lowered resilience during busy or stressful periods, when immune demands are high. By supporting the cellular environment that underlies immune function, light therapy may be incorporated into family routines during times when immune support feels especially important. Allergies (Immune Over-Responsiveness) Allergies are best understood not as a weak immune system, but as an over-reactive one. Seasonal allergies, environmental sensitivities, and recurring sinus or skin flare-ups are all examples of immune responses that are disproportionate to the trigger. Light therapy is sometimes discussed in this context because of its effects on inflammatory signaling, circulation, and tissue response, which may help support immune balance rather than stimulation. In family life, this may be relevant for children with seasonal symptoms, teens with recurring sinus or skin-related reactions, or parents managing ongoing sensitivities. The goal is not to suppress immune function, but to support a more regulated and proportionate response. Choosing Light Therapy Devices for Family Use Families often benefit most from light therapy devices that are flexible, comfortable, and easy to share across different needs and body sizes. Rather than choosing devices based on age alone, it’s helpful to think in terms of treatment area, body size, and intended use. The following overview highlights how different Fringe light therapy devices are commonly used in family settings. Regular Wrap One of the most versatile options for family use, the Regular Wrap can be used on many areas of the body, including legs, back, abdomen, shoulders, and hips. Its adaptable size makes it a popular shared device in households, particularly for preteens, teens, and parents using light therapy for pain and injuries, gut health, immune support, or general recovery. Extra Long Wrap Designed for larger bodies or broader treatment areas, the Extra Long Wrap provides extended coverage for full-length limbs or larger muscle groups. Families often choose this option when greater surface area is needed, while still maintaining the flexibility of a wrap-style device. Head Wrap The Head Wrap is designed specifically for brain-focused applications. It’s adjustable to fit small, medium, and large head sizes and is commonly used in family routines that support emotional regulation, focus, stress resilience, or recovery following head impacts. It's hands-free design makes it easy to use during rest or quiet activities. Neck & Chest Wrap Shaped to contour the neck and upper chest, this wrap is well suited for supporting skin health in the décolletage area while also delivering light to immune-rich regions of the neck and the thymus gland. It’s often used as part of routines focused on skin health, immune support, or seasonal wellness. Face Mask The Face Mask combines red, near infrared, and blue light. Blue light is commonly used for blemish control, making this device appealing for teens dealing with breakouts, while red and near-infrared light support skin tone and rejuvenation, which many parents incorporate into their skincare routines. Multi-Joint Wrap Designed to fit securely around joints such as knees, elbows, or ankles, the Multi-Joint Wrap is ideal for joint-specific or athletic injuries. It’s often used in active households where targeted support is needed for sports-related strain or overuse. Tiny Wrap The Tiny Wrap is a compact, highly adaptable device designed for smaller treatment areas or more precise placement. It delivers red and near-infrared light, as well as blue light, making it especially useful for skin support across different parts of the body. Its lightweight size makes it a convenient option for individuals who prefer a smaller, more focused device, without limiting its use to any specific age group. Rather than relying on a single device, many families find that having one or two complementary options allows light therapy to adapt as needs change, whether that’s supporting recovery after activity, managing skin concerns, or navigating busy, high-demand periods of family life. Here’s a summary of device applications that may be helpful: Device Common Family Uses Fringe Regular Wrap Pain & injuries · Gut health · Immune support · Growing pains Fringe Extra Long Wrap Large muscle groups · Full legs · Back & hips Fring Face Mask Blemish control (blue) · Skin tone & rejuvenation Fringe Neck & Chest Wrap Décolletage skin · Immune-rich neck area Fringe Head Wrap Brain health · Emotional regulation · Focus · Concussion recovery Fringe Multi-Joint Wrap Knees · Elbows · Ankles · Joint-specific injuries Fringe Tiny Wrap Localized skin support · Precision placement · Small body size Conclusion At Fringe, we view light therapy as a foundational part of family health. By supporting core processes such as cellular energy production, inflammation regulation, circulation, and nervous system balance, light therapy can meet families where they are, even as needs change over the lifespan. Thoughtfully designed devices and evidence-informed education make it easy to integrate light therapy into everyday routines, helping families support health, resilience, and recovery in a simple, consistent way.

Introduction: Expanding the Healing Spectrum at Fringe At Fringe, we’ve long championed the healing power of light. Our range of targeted Red Light Therapy (RLT) products—from wraps to panels to precision wands—has helped thousands address localized pain, inflammation, and skin concerns. But now, we’re expanding the possibilities of what red and near-infrared light can do. Introducing the Fringe Full-Body Red Light Therapy Mat. Designed to bathe the entire body in therapeutic light, this mat delivers two synergistic wavelengths: 660 nm (red) and 810 nm (near-infrared). It represents not just a new product, but a paradigm shift in how light can support systemic healing, energy regulation, and biological resilience. This blog explores the science behind full-body RLT, why it differs from localized therapy, and what makes the Fringe mat uniquely suited to support deep, whole-body regeneration. Take Me to the Mat! A Primer on Red Light Therapy (RLT) Red light therapy (RLT), also referred to as photobiomodulation (PBM), is a therapeutic intervention that uses visible red light (typically 620–750 nm) and near-infrared light (750–1400 nm) to stimulate biological processes in the body. Unlike ultraviolet (UV) light, which carries ionizing energy that can damage DNA, RLT uses non-ionizing wavelengths that gently interact with cells to support healing and regeneration. The primary target of red and near-infrared light is cytochrome c oxidase, a light sensitive enzyme in the mitochondrial respiratory chain. When activated by either red or near infrared light, this enzyme increases the production of adenosine triphosphate (ATP), the molecule responsible for cellular energy. This upregulation of mitochondrial function can lead to wide-ranging downstream effects across multiple physiological systems. The therapeutic response to RLT depends on several factors, including wavelength, irradiance (intensity), energy density (dose), treatment duration, and tissue depth. Red light tends to be absorbed in the skin and superficial tissues, making it ideal for dermatological and surface-level applications. Near-infrared light, with its deeper penetration, is suited for reaching muscles, joints, and internal structures. Together, red and NIR light form a biologically compatible spectrum that can support healing from the surface to deeper tissues, making RLT a versatile and non-invasive tool for both targeted and systemic applications. The primary mechanisms by which RLT acts on a cellular level include: Increased ATP production Reduction in oxidative stress and inflammatory markers Enhanced blood flow and lymphatic circulation Stimulation of cellular repair and regeneration As detailed in our blog Top 10 Evidence-Based Uses for Red Light Therapy, RLT has been shown in hundreds of peer-reviewed studies to improve skin quality, reduce pain, accelerate wound healing, support neurological recovery, and more. Most clinical studies have focused on localized RLT, but a growing body of evidence suggests full-body delivery may unlock broader and more systemic benefits. What the Research Says About Full-Body RLT While much of the Red Light Therapy literature focuses on localized treatment—targeting a joint, a muscle group, or an area of skin—there is growing scientific interest in the systemic effects of full-body red and near-infrared light exposure. These studies investigate how full-body RLT influences outcomes like pain perception, inflammation, and functionality in arrange of different conditions. For example: In fibromyalgia, a clinical trial found that four weeks of whole-body PBM led to notable reductions in pain and enhanced quality of life in people with fibromyalgia. In addition, both kinesiophobia and self-efficacy improved in the short and long term, while pain catastrophizing showed sustained improvement at six months post-treatment. Patients with fibromyalgia receiving full body RLT perceived improvements in resilience, physical capacity, and quality of life. In COVID-19, use of either full body RLT or transcranial RLT improved cognitive function, reduced brain fog symptoms, and enhanced quality of life, with whole-body treatment offering systemic benefits. In athletic performance and recovery, full body RLT improved sleep quality and endurance performance over a multi-week training period. It also reduced post-exercise creatine kinase levels and inflammatory markers, suggesting enhanced recovery. It also resulted in immediate improvements in agility performance following a single full body RLT session. A systematic review of full body RLT for exercise performance and recovery concluded that whole-body PBM may enhance recovery, reduce muscle soreness, and improve sleep, although effects on performance vary depending on protocol. In skin health, a study using full-body RLT twice a week for 30 sessions significantly improved skin smoothness, texture, and overall appearance. Collagen density in the skin increased, while roughness and wrinkles decreased. These benefits were still present 60 days after treatment, and the control group saw no such improvements. In patients with cardiovascular disease, a study found that full body RLT using an LED bed reduced blood pressure in about two-thirds of participants with hypertension. The authors noted that heat from the bed may have contributed to this cardiovascular benefit. These research findings suggest that full-body RLT is not limited to surface-level benefits but can influence deeper biological systems such as pain signaling and sleep architecture. While most RLT research has traditionally focused on localized applications, these studies demonstrate the broad potential of systemic light exposure to support full-body wellness. Why Choose Full-Body Over Localized RLT? Full-body red light therapy offers distinct advantages that extend beyond what localized treatment can achieve. Here's why a whole-body approach is often preferable: Systemic and Holistic BenefitsFull-body RLT allows light to interact with and influence multiple systems at once—including the nervous, immune, endocrine, and circulatory systems. This enables the possibility of systemic (meaning whole-body) shifts that are harder to achieve with a localized panel or wrap. A great example of a systemic benefit relates to adipose tissue, which is distributed over the entire body. Red Light Therapy to the abdomen has been shown to have a positive effect on metabolism and inflammation in adipose cells, which could theoretically be even greater with full-body application. Improved Microcirculation and Oxygen DeliveryWhen light reaches tissues throughout the body, it can stimulate nitric oxide release, which induces vasodilation and increases blood flow. This supports better delivery of oxygen and nutrients across large areas—not just the treatment site. Autonomic Nervous System & Vagal Tone ModulationWhole-body RLT may also shift autonomic balance toward parasympathetic dominance, supporting vagus nerve tone and potentially impacting digestion, stress resilience, and inflammatory tone. Structured Water and Long-Wavelength NIRResearch suggests that near infrared light can influence the structuring of water within and between cells. These effects are linked to improved mitochondrial efficiency, protein folding, and overall biological coherence. Applying this wavelength across the entire body may offer systemic restructuring of biological water compartments. Convenience and ComplianceA yoga-style mat makes full-body therapy practical and accessible. Unlike panels that must be repositioned multiple times or wraps that only cover limited areas, mats invite effortless use. You simply lie down and let the light do the work. Uniform Coverage = More Consistent ResultsMany people struggle with dosing consistency when using targeted devices. With full-body RLT, the entire body is treated evenly, promoting balanced systemic signaling and eliminating the guesswork around where to aim the light next. Multi-Goal FunctionalityBecause it delivers light to skin, joints, organs, and fascia simultaneously, full-body RLT can support multiple wellness outcomes—such as pain relief, stress regulation, muscle recovery, and skin rejuvenation—in a single session. These advantages illustrate why full-body RLT represents a meaningful evolution beyond localized treatment. By supporting systemic biological processes, rather than focusing solely on symptom relief in a single area, full-body RLT invites a more integrative model of healing. It addresses not just where discomfort shows up, but the physiological imbalances that underlie it. Whether you're seeking deeper recovery, improved resilience, or foundational support for long-term health, a full-body approach provides a uniquely efficient and comprehensive therapeutic platform. Ready For Whole Body Healing? Light Intensity and Dosing Philosophy As described in our blog, Red Light Therapy Intensity: Why Higher Power Isn’t Always Better for Results, Fringe does not subscribe to the belief that higher light intensity is better. While many commercial devices advertise high irradiance values to appeal to consumers seeking fast results, we take a more evidence-informed approach. The bulk of published human studies demonstrating therapeutic benefit from red and near-infrared light use relatively low-to-moderate intensities, often between 10–50 mW/cm². Higher intensities may increase the risk of tissue overheating or photoinhibition—especially in full-body contexts where large surface areas are exposed. Excessively high irradiance can also create a biphasic dose response, where benefit diminishes or reverses beyond an optimal threshold. Our full-body RLT mat is designed to operate within a safe and biologically effective intensity range, supporting consistent mitochondrial activation without overstimulation. This philosophy is supported by research in which low-intensity, full-body RLT improved pain, recovery, and wellbeing without requiring high-output LED arrays. Why the Fringe Full-Body Mat Is Different The Fringe Full-Body Red Light Therapy Mat is uniquely engineered with two carefully selected wavelengths: 660 nm (red) and 810 nm (near-infrared), found at a ratio of 1:2 (red: near infrared). Each wavelength contributes distinct biological effects and penetrates to different tissue depths, making the mat versatile and capable of addressing surface-level and deep-tissue targets in one session. 660 nm (Red Light): A very well-studied wavelength, 660nm is well absorbed in skin and superficial tissues, making this wavelength ideal for improving skin tone, circulation, and reducing inflammation near the surface. It also supports collagen production, accelerates wound healing, and promotes dermal regeneration. The 660nm wavelength also reduces oxidative stress and improves functionality of tissues. 810 nm (Near-Infrared Light): A well-studied NIR wavelength that penetrates more deeply into muscle and connective tissue, 810 nm is widely known for its effects on mitochondrial ATP production, pain modulation, and nerve repair. It activates cytochrome c oxidase and is frequently used in both sport recovery and neurological research. This deeper-penetrating wavelength also interacts more with water, allowing it to reach deeper tissues with minimal scattering. It may influence the structure of intracellular and extracellular water, potentially enhancing mitochondrial efficiency and protein dynamics. This wavelength composition reflects a systems biology approach to RLT targeting not only the skin and muscle, but also the foundational structures and fluids that support human health. How to Use the Fringe Full-Body Mat To get the most from your full-body red light therapy sessions, consider the following evidence-informed guidance: Session Duration:Start with 10 to 20-minute sessions per day. This aligns with the duration used in most full-body RLT studies showing benefit for pain, recovery, and well-being. Frequency:Use 3–5 times per week. Like exercise, the benefits of RLT accumulate over time with consistent use. Clothing:While recent research has shown that near infrared light can penetrate through clothing, red light can’t, so to get maximum benefit from both wavelengths, exposed skin is ideal. Timing:Some users prefer morning sessions for energy and circadian rhythm alignment; others use it in the evening for relaxation and recovery. You can experiment with timing based on your goals. Consistency is Key:While even one session can feel rejuvenating, the deeper and more lasting benefits of full-body RLT - such as reduced inflammation, improved resilience, and better sleep - come with regular use over weeks to months. Explore a Whole New Way to Heal. Conclusion: A New Paradigm for Whole-Body Healing Targeted red light therapy has clear benefits, particularly for localized pain, injury, or skin concerns. But when the goal is broader—supporting whole-body energy production, recovery capacity, and systemic regulation—a full-body approach becomes especially relevant. Delivering light to a large surface area allows red light therapy to engage not only local tissues, but also circulating blood, immune signaling, and nervous system pathways that influence the body as a whole. The Fringe Full-Body Red Light Therapy Mat combines 660 nm red and 810 nm near infrared light to provide comprehensive, low-stress exposure across the entire body. This approach supports mitochondrial function, circulation, and nervous system balance without relying on high intensities or complex treatment strategies. Full-body light therapy offers a practical way to integrate red light therapy into daily life, supporting resilience, recovery, and cellular health from head to toe.
