It Takes More Than Hormones to Fix Our Hormones

by Dr. Genevieve Newton PhD in Podcasts

Dr. Genevieve Newton sits down with Dr. Anna Cabeca — triple board-certified OB/GYN, author of The Hormone Fix and KetoGreen 16, and host of the Girlfriend Doctor podcast — for a rich conversation on what it actually takes to restore hormonal health. Dr. Cabeca shares how years in conventional practice, combined with her own personal health crisis, pushed her toward a functional and integrative approach built around what she calls the “devil’s triad”: chronic inflammation, adrenal dysregulation, and the interplay of hormone imbalance and insulin resistance.

The keto-green diet is central to Dr. Cabeca’s framework — a combination of ketosis with alkalinizing greens, fiber, polyphenols, and fermented foods that supports insulin sensitivity, brain function, and hormonal balance simultaneously. She explains the brain fuel shift that occurs during perimenopause, and why approaches that worked in your 30s may no longer apply. The conversation also explores the underappreciated role of oxytocin — not just as a bonding hormone, but as a powerful driver of resilience and wellbeing that can be cultivated through gratitude, prayer, and human connection.

A significant portion of the episode focuses on genitourinary syndrome of menopause (GSM) — the constellation of vaginal dryness, atrophy, and urinary symptoms that affects most menopausal women but remains underaddressed. Dr. Cabeca and Dr. Gen walk through a complete pelvic health stack including DHEA cream, water-based lubricant, targeted probiotics, pelvic floor exercises, and the Fringe pelvic wand with vibration. A 74-year-old patient story puts all of it in perspective.

Transcript

Dr. Genevieve Newton: Hi everyone, welcome to the Fringe Podcast. I'm Dr. Genevieve Newton, Scientific Director at Fringe, and I'm here today speaking to Dr. Anna Cabeca. Very excited to have you as our special guest. Dr. Cabeca is the best-selling author of The Hormone Fix, KetoGreen 16, and Menu Pause. She is triple board certified in gynecology and obstetrics, integrative medicine, and anti-aging and regenerative medicine. She holds special certifications in functional medicine, sexual health, and bioidentical hormone replacement therapy. Dr. Anna is also known as the Girlfriend Doctor and hosts the podcast by the same name, where we spoke about a year ago. We're going to pick up our conversation and talk all things menopause. Tell us how you got here — you started off as a more conventional OB/GYN and then shifted into this functional integrative side. How did that happen?

Dr. Anna Cabeca: I grew up in a culture of first-generation Americans — a lot of food as medicine. I chose osteopathic medicine because of the philosophy of empowering the body to heal itself: alignment, address the issues, the fascia is connected to everything, can't treat one part of the body without treating the rest. Then I did residency at Emory University, one of the best allopathic institutions for OB/GYN. Early on in private practice, I had a patient who came in — 63 years old, history of ductal carcinoma in situ of the breast, it hurt to have sex, she was dry, no doctor would give her hormones. She loved her husband, couldn't have sex because it was too painful, and she said she'd rather die than live this way. And I was like: my job as a physician is not to say the case of do no harm means do nothing. So I dug into the research. She was the president of a biotech company and we dug in together. We found we could use DHEA, testosterone, vaginal estrogen — no contraindications. I read all the research. We wanted to stay away from progestins for sure. And I started working with her. From there, other clients came in — the women with breast cancer, other GYN cancers, over a certain age, just left to suffer. That was completely unacceptable to me. And I started on this journey creating solutions, understanding that it takes more than hormones to fix our hormones. Always address the underlying issues. When a patient comes in with a diagnosis, what caused that diagnosis? Did we address the underlying issues? For me, this is truly my passion.

Dr. Genevieve Newton: You have been a long-time champion for women who are suffering from these issues. What are the root causes you see so often in your practice?

Dr. Anna Cabeca: That comes down to three things — I call them the devil's pitchfork. If we can address these three things, we’re going to heal or reverse 99% of the diagnoses that come up. Number one: inflammation. There is no disease without inflammation that exists in an alkaline, non-inflamed body. Number two: adrenal dysregulation. Our foot on the cortisol pedal, the adrenaline pedal — we're firing up our system, which also contributes to inflammation. Number three: hormone imbalance. With that hormone imbalance, I'm going to talk about insulin resistance. As we get older, reproductive hormones decrease but insulin and cortisol increase. We have to become more insulin sensitive. We have to support our bodies' natural ability to make and use hormones more efficiently. There are so many hormone disruptors. The answer isn't piling on more hormones — believe me, I am a hormone prescriber. I've done this for 30 years. I use bioidentical hormones. But it's really important to address the underlying issues first: empower our bodies to use and produce our hormones most effectively, and avoid, remove, and cleanse our systems from things that are disrupting our hormone receptors, production, or acting as hormone mimickers.

Dr. Genevieve Newton: If I came into your office suffering from the devil's triad, what would you tell me to do from a dietary perspective?

Dr. Anna Cabeca: Foundationally, I call it keto green. A way to get into healthy ketosis — not butter and bacon keto, but getting into ketosis in a healthy way while also focusing on the alkalinizers: the greens, the fiber, low glycemic nutrients, polyphenol-rich foods that feed our gut microbiome. The most important population in the world that I want to protect is the microbiome — the healthy, protective microbiome. So the keto green foundational nutrition: I created medicinal menus that help us get into ketosis and decrease inflammation, improving alkalinization. Each meal has a healthy high-quality protein, good alkalinizing greens or phytonutrients, a healthy fat, and a fermented food. That combination is so empowering and helpful. Food is medicine, or it can be disease-promoting.

Dr. Genevieve Newton: You were really far ahead of the curve because with Atkins and early keto, there wasn't this recognition of the need to support the microbiome and provide fiber. Have you had to fight to get this information accepted?

Dr. Anna Cabeca: Absolutely. I've collected thousands of clients that have gone through surveys pre and post my Magic Menopause program. I'll publish it someday. In my mid-to-late forties, hitting that perimenopausal spiral — even though my hormones were dialed in, I was experiencing the 5, 10, 20 pound weight gain without doing anything different. The mood swings, irritability, monster within me, intolerance, burnout, disconnect. Even as a hormone specialist with my hormones dialed in, I was experiencing this weight gain and brain fog. I knew the keto or low carb diets could help. But I felt what I called keto crazy — not keto flu, but something wasn't right. Something if men can do keto differently than women. No one had really studied it in women, let alone menopausal women. So I started digging in. I checked my urine pH — as acidic as the paper could read. And think as a gynecologist: acid in your bladder long-term is going to create incontinence, interstitial cystitis, infections, urgency symptoms. We know alkaline urine pH is associated with lesser metabolic disease, diabetes, cancer, bone loss. So I needed to add alkalinizers back. I started thinking about cultures that eat ketogenically — the Inuit people, for example. They make fish bone broth. That's the minerals. The minerals are huge alkalinizers. I started adding more minerals, microgreens, sautéed beet greens, kale soup. The alkalinizers were key. And all of a sudden the weight released and my mood lifted. I had this sense of peace — nothing in my life had changed. Still single mom of all my kids, soul breadwinner, lots of stress and trauma. But I felt that peace. And as a result, my mornings changed completely. And I realized it wasn't just what we eat. Cortisol — you can be eating all that good nutrition but be stressed out and angry, and cortisol creates that acidic environment. Cortisol is the key that unlocks the door to those intact cell membranes. Oxytocin does the opposite. The practice of gratitude, presence, joy, prayer, meditation, getting out in nature — these things increase oxytocin and seal that gate, creating alkaline urine pH. So I took this and called it my Magic Menopause program. I took my most difficult patients through it — the stubborn ones where I couldn't get the needle to move. And every single one of them felt better within a few weeks. That became my Magic Menopause program, launched in 2014.

Dr. Genevieve Newton: I love that you have that spirit connection in there because that's been my personal experience too — it's a triad of mind, body, spirit in terms of being healthy, and you really can't have one without the others. Can you speak to the biochemical aspect of the keto-green approach in perimenopause specifically?

Dr. Anna Cabeca: In 2015, a research article was published looking at MRIs and SPECT scans of women's brains, examining glucose metabolism. Glucose metabolism or gluconeogenesis in the brain is an estrogen-dependent phenomenon — it flows along the decline of progesterone more so than estrogen, though progesterone is not well studied in the female brain. During the time period when progesterone and estrogen start to decline, your brain is actually starving for fuel. It’s not using glucose as much. So you forget your words, you don't know why you went into a room. It's a very challenging and concerning experience. But the use of ketones for fuel in the brain is not hormone-dependent. When I shifted into ketosis, my memory was there, my clarity was there. And with the alkalinization in that healthy way, really focusing on feeding the gut microbiome, addressing our physiology in a supportive low-inflammatory way — that's key. That period from roughly 35 to 60 is a period of neuroendocrine vulnerability. But through lifestyle and nutrition, we can shift that. And I've proven: through the keto green approach, in as little as ten days, hot flashes can be gone. Because insulin resistance is what's driving the hot flashes — they're symptoms of insulin resistance, not just estrogen insufficiency. If you create insulin sensitivity, you've just improved longevity.

Dr. Genevieve Newton: I turned 50 this year and I'm definitely menopausal. It hasn't been a super challenging experience so far — I’m very focused on my diet and my spiritual wellbeing. There's this ongoing conversation among friends about hormones. Today many people think you can't be well through this transition without replacing hormones. What's your take?

Dr. Anna Cabeca: It's always about being in alignment with the patient's personal preferences and practices. I will say — I personally will be on my balance cream and my Jolva cream until I die. And probably some testosterone. I want to keep my bladder as healthy as possible. But I also have clients who chose not to use hormones. And nutrition, lifestyle, and nature are really important interventions for them. When I walked the Camino de Santiago, one of the most amazing women I saw was in her late seventies — all smile lines, laugh lines, body like a twenty-year-old, strong, agile, walking fast, energetic. Not on hormones. Not on handfuls of supplements. Not biohacking herself. And I honor that absolutely. I think: if I was hiking the Camino or living in the Amazon, waking up with sunrise, going to sleep with sunset, not exposed to EMFs, not burning the candle at both ends — maybe I wouldn't need hormones or as much. We get so much more from nature and sunshine than just vitamin D. In the Blue Zones, not one of the factors was supplements or hormones. It was connection, all the oxytocin-increasing practices. The most powerful pharmacy in the world is the one in our own body. So tapping into that — that's creating your Blue Zone. It's not a heck yes or a heck no on hormones. It has to be in alignment with our lifestyle and our choices.

Dr. Genevieve Newton: At Fringe, our philosophy has always been not about biohacking or super-physiological doses and really high intensities. With supplements: what are we missing that we really can't get from our diet anymore, and can we get that from a food-based supplement? With red light therapy: let's mimic the intensity of the sun to bring in some of what people are missing from their interior-focused lifestyles. If you ask us whether it's better to go out in the sun — absolutely yes. We want you to do that. In the context of menopause and genitourinary syndrome specifically — those urinary and sexual symptoms — how do you see non-pharmacological options, including light-based therapies, fitting in?

Dr. Anna Cabeca: I think it's essential. I talk about vulvar topical hormonal therapy, red light therapy, vaginal microbiome support therapy — all of this is critical to vaginal health and wellness. Even my clients in their 80s, I have them using topical hormones in this area because incontinence, urgency, dryness all make a difference. And not just red light — the reason I recommend the Fringe wand is it's red light with vibration. Vibration helps with blood flow and vascularity. It works better in hormonally sensitive tissue, making it more flexible and more elastic and supporting natural glandular secretions. When I recommended the red light vaginal and vibration therapy to my patients, they were on board immediately because they understand how red light is affecting their skin in other areas — helping with aging, helping with healing, it's collagen-promoting. So let's add that down there as well. If we think of the healthy pelvic floor stack, that's definitely included. And there's no negative risk that I know of. I have a 74-year-old patient I love telling this story about. I asked her in the office: how's your sex life going? She said, Dr. Anna, in this last year since we fixed things down there, it has been the best in our marriage. Fifty years married. And she said: we've always loved each other, sex was okay, but over the years it was something we did. We love each other and care about each other. But since addressing everything — using Jolva, adding the vaginal microbes, the Lactobacillus crispatus supplementation, adding red light therapy — they increased the quality of their intimacy and relationship. She said: not just in the bedroom, but in all areas of life, we're laughing more together, having more fun. That's oxytocin. When we create that safety and trust by addressing those issues, by addressing clitoral atrophy, vulvovaginal atrophy, dryness — the body feels safer, has more pleasure, more enjoyment. That's game changing. That's why I champion vulvovaginal care.

Dr. Genevieve Newton: I would love for you to get detailed with us about that pelvic stack. If you wrote this down on a prescription pad for a patient, what would it look like?

Dr. Anna Cabeca: Number one: I start clients on Jolva. I started compounding hormones with DHEA in the 1990s, and Jolva is the result of that evolution — plant stem cells and DHEA in a very emollient, absorbent base. Typically I tell clients to start every other day for the first one to two weeks, then daily, applied clitoris to anus, the vulvar labial tissue. That naturally helps with moisture. Number two: my new lubricant Velvee — aloe, hyaluronan, clean, water-based, propanediol, no propylene glycol, no parabens. It's a great lubricant during sex and also soothing. Number three: VB probiotic — the vaginal targeted probiotic with high quality strains, including Lactobacillus crispatus. Key. Number four: pelvic floor exercises. Muscle is magic and the most important muscles are in the pelvic floor — keep them strong and healthy. Number five: red light and vibration. The reason I like the Fringe wand over some others is it's a narrower diameter. You also have the blue light option, which for any inflammation, infections, or post-coital tenderness, you can use that blue light and it can really cool things down. For the probiotics: initially, especially if you haven't been on any in a while, I typically have my postmenopausal women on it at least three months — two capsules a day for two to three months, then take a break, but integrate it back in periodically. For younger patients in their 20s, just doing one course of the probiotic should be fine. I think it's one of those things where like the seasons change, do a bottle every quarter just for that preventative repopulating of healthy bacteria. Because as I've been doing vaginal cultures on clients in their twenties, thirties, forties, and beyond, I'm not seeing the healthy bacteria. I see a lot of dysbiotic or just aseptic vaginas from antibiotic use, hormone disruptors, washes. All of that has affected the vaginal microbiome. Adding in a vaginal probiotic — I have patients who've been on my Jolva product for over ten years and then we add in the vaginal probiotic and they're like: my God, even better. Not getting up at all at night to pee. These are the changes I'm hearing from the community.

Dr. Genevieve Newton: I love how comprehensive this toolkit is, and it's also not onerous — it's really manageable. It's a very different message than what a lot of women are getting today, which is just go on hormone replacement therapy and use vaginal estrogen. There's a lot more to the story. Is there something you want to add on the hormone side?

Dr. Anna Cabeca: Yes. In every prescription vaginal estrogen, unless it's compounded, there are hormone disruptors in it — that's what gives it the shelf stability for years. Those ingredients can actually cause disruption of the vaginal mucosa cells and disruption of the microbiome. So there's a double-edged sword. Yes, estrogen can help the mucosa. But compared to DHEA or testosterone, it's not addressing the deeper layers. I've been following the work of Dr. Ferdinand Labrie out of McGill University for over two decades. Vaginal DHEA increases the strength of the muscle walls. Topical use, together with pelvic floor exercises, improves glandular secretion. According to the published research and my clinical experience, vaginal DHEA and vaginal testosterone work so much better than estrogen alone. So much better.

Dr. Genevieve Newton: Thank you for sharing all of that. Where can people find you?

Dr. Anna Cabeca: Easy to find me at dranna.com — D-R-A-N-N-A dot com. And on social media at The Girlfriend Doctor. Check out my YouTube channel. My books — The Hormone Fix, KetoGreen 16, and Menu Pause — are available anywhere books are sold.

Dr. Genevieve Newton: Amazing. Thank you so much, and thanks everyone for joining us today. We'll look forward to seeing you again.

Red Light Therapy for Women's Health: 10 Ways It Can Support Your Body - Fringe

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.

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.

How Red Light Therapy Supports Abdominal and Pelvic Health - Fringe

How 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.

Introducing the Fringe Red Light Therapy Clinical Pad - Fringe

Introducing 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.
