Top 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.

Red 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.

Full-Body Red Light Therapy: A New Era of Healing
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.

Red Light Therapy 101
If you’ve just bought for your first red light therapy product, or are considering getting one, you’re probably wondering “how the heck do I use this thing?” Well look no further: Here is your go-to guide for all things red light therapy! 1. What exactly is red light therapy? Red Light Therapy, also known as photobiomodulation (PBM), may be used to support the health of cells and tissues throughout the body. Defined as the use of red and/or near infrared (NIR) light to influence biology, most modern PBM devices emit both types of light, which have similar effects but penetrate the body to different depths. Red light is visible to the human eye, while infrared light is not, although it can be felt as heat. While early research on PBM used primarily lasers, more recent research has found that LED’s can also be used, which also have the advantage of applying light to a larger area of the body as well as an improved safety profile. The use of LED in red/NIR devices has also greatly reduced the cost of treatment, making it something that can be done in the comfort of one’s own home. 2. What is red light therapy used for? There are many mechanisms by which red light therapy affects the body, with the most well-known being increasing the synthesis of ATP (the energy currency of the cell) through effects on the electron transport chain in the mitochondria. The link between red light therapy and improved mitochondrial function has been well established. This increased supply of energy can be used to do many types of cellular work, including healing, growth, maintenance, and repair. There are thousands of published studies showing the efficacy of red light therapy for a wide range of health applications, ranging from general support for healthy cells to improving brain function in Alzheimer’s Disease patients. 3. What are the wavelengths of light used in Fringe red light therapy products? The red wavelengths used in light therapy range from 600 to 700 nanometres (nm), with the unit nm referring to distance the light wave travels in one cycle. The near infrared light used in light therapy ranges from 800 to 1100nm. All the Fringe red light therapy wraps (except for the head wrap) and the red light therapy panel use red light at 660nm and near infrared light at 850nm. The Fringe head wrap uses red light at 660nm, near infrared light at 810nm, and near infrared light at 1050nm; the addition of a second wavelength of near infrared light is to enhance penetration into the head. The Fringe face mask uses red light at 630nm, near infrared light at 830nm, and blue light (yup, not red at all!) at 415nm. Blue light is included in the face mask due to its ability to control blemishes. Importantly, the spectrum of blue light in the face mask mimics the blue light from the sun and is different from the artificial blue light that is emitted from electronic devices. Our wavelength selection for each product was informed by an analysis of scientific studies of red light therapy. 4. How do I know which Fringe red light therapy products is right for me? Fringe makes two types of red light therapy products: Panels and wraps. Our wraps come in several different shapes/sizes, including a regular and long wrap that have a rectangular shape, a head wrap, a face mask, and several joint specific wraps (knee, foot/ankle, shoulder/neck, elbow/wrist). All our products deliver both red and near infrared light (plus blue light in the face mask) at approximately the intensity of the sun - more on that in #5! You can help a wide variety of health conditions with either a panel or a wrap – but it is important to understand the differences between them so that you can choose which product best suits your needs. To choose the right product for you, first identify what health goals you want to achieve. Both panels and wraps can be used to treat pain, inflammation, and a wide range of health conditions. Panels also can help with sleep & mood as they create a visible ambient light, and they can be used to treat a larger surface area. When using a wrap, the red wavelengths are barely visible, so the additional health benefits from ‘seeing’ red light (sleep & mood) are not available. Panels are better suited to treating regional pain, while wraps work better for localized pain. Second, identify what area(s) of the body you want to treat. If there are multiple body parts to be treated, you should choose a versatile device like an red light panel or non-specific wrap (either the regular or extra-long wrap) that can easily be applied to different target areas. Panels can be used to treat most body parts, including the face, chest and back. Non-specific wraps work well on most body parts, except the face and head. If you want to target a particular body part (such as the face), you can choose a product that is designed specifically for that area (for example, a mask). Our specific wraps (head, face, and joints) are uniquely designed to be used on certain body parts, and may be a bit more comfortable, especially on the head and face. Third, you should consider how and where you intend to use the product. If you would like to have the option of moving around during your treatment, you would do better with a wrap rather than an panel, since wraps are battery powered and portable. Panels are plugged into an electrical outlet and require that you stay stationary during your treatment. Every person’s needs are unique, but there are many different device options to choose from. 5. How intense is the light delivered by Fringe red light therapy products? Light intensity refers to the amount of light being delivered by a device. It is also referred to as irradiance. This describes the amount of light energy your skin receives over a period of time and is usually measured in mW/cm2. The amount of light your skin receives, which is a function of time and intensity, is referred to as the “dose”. Another way to describe the dose of light received is in Joules/cm2 or Total Joules, with Joules being a unit of energy. In terms of intensity, it has been found that it is ideal to mimic the intensity of the sun, which is around 24 mW/cm2 at the skin. This is described as the “sweet spot” between higher intensities, which can have harmful effects, and lower intensities, which will have no effect at all. Our target intensity is 20-40mW/cm2. This is the approximate intensity of the sun, and we think the sun knows a thing or two about healing! Many companies claim to have over 100mW/cm2 at 0 inches. Man, that would be HOT! Higher irradiance or power does not mean better results, if the dose is too great – the benefits are negated! There is a “photoinhibitory” effect that occurs at higher intensities that you want to avoid. Our panels emit light at a higher power than our wraps, but that does not necessarily mean more light is absorbed into our skin. When the light source is 4-6 inches away from our skin, a large portion of the light is scattered before it reaches our skin. Due to the indirect nature of red-light therapy panels, the units have a higher power rating (192W) so we can accommodate for light that is lost and deliver the appropriate intensity of light for a treatment. Wraps, which are in direct contact with the skin, have less power (60W) so we can deliver the appropriate intensity of light for a treatment (30 mW/cm2). Both panels and wraps are designed to deliver the same intensity of light during a treatment: approximately 30 mW/cm2. Think of your Fringe Light as a way to safely supplement the sun (or the wavelengths from the sun) that offer us the most healing benefits. 6. What are the treatment parameters that I should follow? Our recommendations regarding treatment parameters can be considered flexible, but there is one thing to make note of: it’s possible to overdo it! The consequences of too much red light therapy rarely manifest as unpleasant symptoms, unless you’re using a very high intensity light, which can heat the tissue; instead, there just isn’t a therapeutic benefit. The good news is that it’s easy to stay within the therapeutic window by following a few simple guidelines when it comes to distance, time, interval, and frequency. Distance: Since red light wraps are applied directly to the skin, there are no distance considerations to make note of. Direct skin contact means less light reflection and higher light absorption. The near infrared light in the wraps generates heat, which should feel warm but not hot. If the temperature is uncomfortable, you don’t have to move the wrap away from the skin; instead, just reduce the intensity of the light by pressing the intensity button, which looks like a sun. With a panel, the further away you are the less light gets absorbed by the skin. This is due to reflection losses, since between 60 and 80% of the light is reflected away from the skin. There is also less penetration into the skin as distance from the panel increases. We recommend being positioned six inches away from the panel during a treatment; at this distance, the intensity of light will be at our target of 30mW/cm2. If you are further away from the panel, the intensity will be lower, and if you’re closer, it will be higher. A higher intensity will require less time to deliver the same dose of light, while a lower intensity will require more time. If you’re using the panel to create ambient light in a room, it can be used in the same way as any other light source. Time: Our recommended treatment times range from 10 to 30 minutes, depending on what it is being used for. Our wraps all have a 20-minute built in timer, while our face mask has a 10-minute timer, and the panel has timers for 10-, 20-, and 30-minutes. Using the timers will ensure that you don’t overdo your light exposure and negate the therapeutic effects. Interval & Frequency: Interval refers to number of sessions per day, while frequency refers to number of times per week. The important thing to consider here is that the effects of red light therapy can cumulative if they are applied in close proximity. Since the cellular response can last from 24 to 48 hours, doing treatments more than once per day on the same area is not recommended, since repeated high doses will be counterproductive. For best results, we recommend using red light therapy between 3 and 7 times per week, with no more than one treatment per day. 7. Are there any precautions I should be aware of? The safety of red light therapy has been demonstrated in thousands of research studies. However, there are some precautions to be aware of before you begin your therapeutic journey. Photosensitivity is the main contraindication to red light therapy. If you are sensitive to light, or are using medications that increase light sensitivity (see https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7672668/ for a recent list). On the other hand, if you can comfortably spend 20 minutes out in the sun without experiencing any adverse effects, red light therapy should be perfectly fine. (Note – this applies to Fringe red light products, which are at the approximate intensity of the sun, and may not apply to higher intensity products from other companies). Here are some other precautions to consider. Please don’t: Stare directly at the LED lights with your eyes open. Allow children to use the device without adult supervision. Use on infants. Use while sleeping. Exceed 30-minute treatment times. Use on open fresh wounds. Use in combination with lotions, balms or other topical products that contain heat producing ingredients. Ice before or after red light therapy. Red light therapy has been found to be safe to use during pregnancy, but we still recommend checking with your health care provider to see if they think it’s appropriate. They can assess your unique health needs and determine if red light therapy is right for you. Conclusion Red light therapy is safe, effective, and very easy to use. With several device types available, it’s easy to find one that meets your needs. Fringe red light therapy products are a great addition to a home care health toolbox. Give one a try!

Are EMFs Harmful or Healing? Understanding Natural, Manmade & Therapeutic EMFs
EMFs Friend or Foe? EMFs are a hot topic of discussion these days, especially on social media. Many people are (rightfully) concerned about excessive EMF exposure, but most are confused about exactly what EMFs are, the differences between man-made and natural (sometimes called native) EMFs, how they affect our biology, and how EMFs (good and bad) are produced by the myriad devices we use each day. In this article, we will dig into all of this and more, with the goal of educating and empowering consumers to make safe, healthy choices about EMF exposure. What are EMFs? EMFs are produced by the movement of electrically charged particles and consist of two inseparable components: electric and magnetic fields. When these fields oscillate, they travel through space as electromagnetic radiation. While some EMFs remain close to their source (like static electric or magnetic fields), others radiate outward and can interact with biological systems. Understanding how they behave - and how the body responds - is key to using them wisely. EMFs vary in characteristics, including: Frequency – how often the field oscillates per second (measured in Hz). Wavelength – the distance between wave peaks. Intensity – the strength of the electric or magnetic component. Waveform – the shape of the wave (sine, square, etc.). Coherence – how synchronized or orderly the waveforms are. Pulsing – whether the field is continuous or switches on and off rhythmically. Biological impact depends not only on these factors, but also on how close the field is to the body and whether exposure is short-term or continuous. These details matter more than whether an EMF is “natural” or “manmade.” Natural vs. Manmade EMFs Natural EMFs are those the body evolved with over millennia. Sunlight, for instance, provides visible light as well as invisible ultraviolet (UV) and infrared (IR) rays. The Earth itself generates a powerful, steady magnetic field and a weak but essential electric field. Natural resonances like the Schumann frequencies pulse in extremely low frequencies (ELF), helping regulate brainwaves and circadian rhythms. These EMFs tend to be low in intensity, rhythmically patterned, and biologically coherent. They fluctuate in ways the body recognizes, often in harmony with other cycles, such as sunrise and sunset, weather systems, and seasons. They support functions like sleep, hormone balance, mitochondrial activity, and mood. Manmade EMFs have become a dominant presence in our environment over the last century. These include: Power lines and household wiring – Power lines emit ELF electromagnetic fields that oscillate in sync with the electrical grid. Power line fields are continuous and pervasive, especially in urban and suburban areas, while devices like power cords, and chargers emit ELF fields if they are powered. TV and radio broadcasts - Traditional broadcast systems use a wide range of radio frequencies to transmit audio and video signals. Though distant from the body and less intense individually, they contribute to the overall EMF environment. Cell Towers, Smartphones, Wi-Fi, and Bluetooth - Cell towers and phones emit pulsed, modulated microwave signals for voice and data. Bluetooth is considered a low-power technology, but because devices like earbuds and wearables are in constant skin contact, biological exposure may be more significant than power levels suggest. Wi-Fi routers emit pulsed high frequency radiation to transmit date wirelessly throughout home and buildings. These EMF sources expose users to high frequency radiation almost continuously. Smart Meters - Smart meters emit sharp bursts of high frequency radiation, often hundreds of times a day, to transmit utility data wirelessly. Their signals fall in the sam range as Wi-Fi but are uniquely problematic due to proximity to living spaces and frequent pulsing. Appliances and electronics - Appliances and electronics often produce stray electric and magnetic fields, especially when plugged in. These EMFs differ not just in source, but in structure. They are often pulsed, modulated to carry date, emitted 24/7, and delivered at much higher intensities or in close contact with the body (such as ear buds or cell phones). They are biologically novel, meaning the body hasn’t had evolutionary time to adapt to them. EMFs emitted by these sources contribute to what is often called “electrosmog”, which can be described as an invisible haze of artificial electromagnetic radiation that now fills our homes, workplaces, and public spaces. As more wireless and electronic technologies are layered into daily life, the electrosmog EMF load continues to grow, creating a baseline level of exposure that is unprecedented in human history. To put this into context, it is estimated that exposure to EMFs around the 1Gz frequency band has increased by more than a quintillion times in just over a century. Therapeutic manmade EMFs, on the other hand, are intentionally designed to support health and healing. The two most used therapies are: Photobiomodulation Photobiomodulation is the use of specific wavelengths of non-ionizing light to influence biological function, particularly at the cellular level. The use of red and near-infrared light is commonly referred to as Red Light Therapy and is typically delivered through panels or flexible wraps. Research suggests that the most effective light intensities fall within a range that is comparable to safe levels of natural sunlight. By mimicking the wavelengths and gentle intensity of natural sunlight, these devices help recreate the EMFs of natural light in a targeted, therapeutic way. Pulsed Electromagnetic Field Therapy Pulsed Electromagnetic Field (PEMF) Therapy uses pulsing magnetic fields to stimulate biological processes in the body. While the Earth’s magnetic field is static and steady, PEMF therapy introduces rhythmic pulses to mimic natural patterns (such as biological electric rhythms), making the field dynamic and biologically engaging. By pulsing at frequencies that align with Earth-based rhythms, such as the Schumann Resonance (~7.83 Hz), PEMF therapy delivers magnetic fields designed to support cellular repair, circulation, and nervous system balance. Not All EMFs Are Harmful It’s easy to label all EMFs as dangerous, especially in a culture increasingly aware of electrosmog. But not all EMFs are harmful, and some are profoundly beneficial. Here’s what research has shown across the spectrum for the different types of EMFs present in our environment: Natural EMFs: Sunlight and Circadian Rhythms -Sunlight acts as the body’s primary circadian pacemaker, helping synchronize the sleep-wake cycle, hormone secretion, and metabolic processes through direct input to the brain’s suprachiasmatic nucleus. UVB and Vitamin D Production - Ultraviolet B (UVB) radiation stimulates the production of vitamin D in the skin, which supports immune function, bone metabolism, and has been linked to improved mood and reduced risk of depression. Sunlight and Serotonin - Sunlight exposure may boost mood through mechanisms beyond vitamin D—specifically by increasing serotonin levels in the brain, a neurotransmitter associated with calmness, focus, and emotional stability. Schumann Resonances and Brain Activity -Schumann resonances—natural electromagnetic standing waves centered around 7.83 Hz—closely align with alpha brainwave activity and may play a role in regulating mental states, emotional balance, and sleep cycles. Earth’s Magnetic Field and Biological Regulation - The Earth’s static magnetic field, though constant and low in intensity, has been linked to biological processes such as orientation, circadian timing, and melatonin regulation. Some studies suggest it acts as a stabilizing background influence on the nervous system. Ionizing Radiation from Natural Sources - Not all natural EMFs are inherently beneficial. Overexposure to ultraviolet radiation from the sun can cause DNA damage, accelerate skin aging, and increase the risk of skin cancer. Other forms of natural ionizing radiation (like cosmic gamma rays and solar X-rays) can also damage cells and contribute to background radiation exposure. Therapeutic Manmade EMFs: Photobiomodulation – Photobiomodulation (especially red/near infrared light therapy) has been shown to reduce pain and inflammation, support healthy circulation, and speed up healing in both skin and deeper tissues. It works by improving energy production inside cells and modulating oxidative stress, making it useful for everything from muscle recovery to wound care. Studies also suggest benefits for mood, brain function, athletic performance, and skin rejuvenation. PEMF (Pulsed Electromagnetic Field Therapy) - PEMF therapy has been shown to reduce inflammation, increase blood flow, promote tissue regeneration, and even support healing of bone and tendon. It has been found to be helpful in supporting athletic performance, speeding recovery from exercise, and preventing injuries. Non-Therapeutic Manmade EMFs: Oxidative Stress - Exposure to non-ionizing EMFs, such as those from Wi-Fi and mobile devices, has been associated with increased oxidative stress. This oxidative stress can lead to cellular damage and has been implicated in various health concerns. Disruption of Calcium Signaling - EMFs can activate voltage-gated calcium channels, leading to elevated intracellular calcium levels. This disruption in calcium signaling can affect numerous cellular processes and has been linked to potential health risks. DNA Damage - Research indicates that exposure to non-ionizing EMFs can cause genetic damage, such as DNA strand breaks and chromatin conformation changes. Such genetic alterations may increase the risk of mutations and have been observed in various cell types. Circadian Rhythm Disruption – Although research has been mixed, EMF exposure may affect melatonin production and disrupt circadian rhythms. This interference with the body's natural sleep-wake cycle can have broader implications for overall health. Reduced Fertility - Studies have found that non-ionizing EMFs can negatively impact female reproductive health (including effects on oocytes, ovarian follicles, hormonal balance) and sperm count. These changes may lead to decreased fertility and other reproductive issues. ______________________________________________________________________________________________ Many natural EMFs, like sunlight, are essential for human health. Therapeutic EMFs harness these beneficial frequencies and structure them in a way the body can use. On the other hand, non-therapeutic manmade EMFs - those not designed with biology in mind - have been linked to biological harm. _____________________________________________________________________________________ Manmade EMFs Done Right Not all EMF-based therapies are created equal. While devices used for Red Light Therapy and PEMF devices can offer profound health benefits, they can also unintentionally introduce harmful EMFs into the body—especially when the devices are poorly designed. High levels of magnetic field emissions, flicker, stray current, and wireless communication features like Bluetooth can all contribute to a hidden "EMF load" that undermines the very benefits these therapies are meant to deliver. Therapy that heals, not harms At fringe, we believe that therapeutic EMF devices should support the body, not stress it. That’s why our Red Light Therapy products are engineered with EMF-conscious design principles that prioritize user safety. By minimizing unnecessary electromagnetic exposure and mimicking natural EMF patterns in both wavelength and delivery, our devices provide powerful therapeutic benefits without adding to the invisible burden of electrosmog. Here's how we do it No Bluetooth or wireless connectivity – this eliminates constant RF emissions. External power supply on our panels – keeps electric & magnetic fields away from the body. Flicker-free light output – supports nervous system regulation & avoids sub-perceptual stress. Biomimetic wavelengths and irradiance – replicates natural red & near-infrared light from sunlight. Battery-powered wraps – eliminate wall current entirely for a low-EMF experience during use. Safe & biologically aligned Meanwhile, many "smart" therapeutic devices on the market prioritize app control and convenience over biological safety. These features often involve permanent Bluetooth or Wi-Fi connectivity, keeping RF radiation active near the body, even when the device is not in use. What’s marketed as “smart” is often out of sync with the body’s natural biology and may ultimately do more harm than good. When it comes to manmade therapeutic EMFs, smart design means staying close to nature and using modern engineering to deliver powerful, biologically aligned therapies without introducing avoidable stressors. At Fringe, that’s our commitment: Therapy that heals, not harms. Conclusion EMFs aren’t inherently friend or foe. They’re simply the products of nature and technology. Some are natural (like the rhythms of sunlight or the Earth’s magnetic field) while others (like the constant digital noise from wireless networks and power grids) can disrupt biological balance. The question isn’t whether EMFs are good or bad, it’s whether they’re in harmony with the systems our bodies are built to understand. At Fringe, our devices are built to emit EMFs that heal, not harm. We design every product with intention to reduce invisible stress, align with nature, and deliver therapeutic energy in its most biologically compatible form. Our Red Light Therapy products are designed with smart, low-EMF engineering: no Bluetooth, no flicker, external power supplies, and biologically aligned wavelengths and intensity. We believe therapeutic EMFs should support healing without adding to the body’s invisible electrosmog burden, and we build every product with that principle in mind.

Light & Vibration Therapy – An Aid for Incontinence?
Urinary incontinence is one of the most common pelvic health issues affecting women in the US, with a recent survey finding that more than 60% report having the condition, and more than 30% report having symptoms at least every month. Despite the widespread prevalence, it remains a topic that most are reluctant to talk about. Whether it’s the occasional leak while laughing or a more persistent urgency that disrupts daily life, incontinence can erode confidence, limit activity, and affect intimate relationships. Despite how common it is, many women are left to navigate urinary incontinence alone, unsure where to go for support or what options are At Fringe, we believe that women deserve real, research-backed tools to care for their pelvic health from the comfort and privacy of their homes. The Fringe Pelvic Wand was designed with this in mind, and is a therapeutic device that combines red, near infrared, and blue light therapy with customizable vibration therapy to support pelvic tissue, muscle tone, circulation, and microbial balance. In this article, we’ll explore the science behind light and vibration therapy for urinary incontinence and describe how the Fringe Pelvic Wand can be a practical, empowering part of your daily pelvic health routine. Understanding Urinary Incontinence Urinary incontinence isn’t a single condition but rather a symptom with many potential causes. The two most common types include: Stress Urinary Incontinence: Leakage caused by pressure on the bladder during movement, coughing, or laughing. This is often due to weakened pelvic floor muscles or connective tissue. Urge Urinary Incontinence: A sudden, intense urge to urinate, sometimes followed by involuntary leakage. This is typically related to nerve dysfunction or overactive bladder signals. Factors like pregnancy, childbirth, menopause, hysterectomy, obesity, and aging all increase the risk of developing urinary incontinence. Conventional treatments range from pelvic floor exercises to medications, physical therapy, and in some cases, surgery. But many women are seeking non-invasive, natural tools to improve symptoms, especially those that can be used at home. That’s where light and vibration therapy come in. How Light Therapy Supports Pelvic Health Light therapy, also known as photobiomodulation, involves applying specific wavelengths of light to tissue to stimulate healing, reduce inflammation, increase circulation, and modulate biological processes. The Fringe Pelvic Wand includes three therapeutic wavelengths: Red light (630 nm): Promotes collagen and elastin synthesis, reduces inflammation, supports tissue healing, through mechanisms including mitochondrial energy production and improving circulation Near-infrared light (830 nm): Has affects similar to red light but penetrates more deeply. Blue light (415 nm): Offers antimicrobial effects, especially for yeast and bacterial infections So how does this relate to urinary incontinence? Improving Tissue Strength & Elasticity Red and near-infrared light have been shown to increase the synthesis of collagen and elastin. These proteins are integral to maintaining the strength of the vaginal wall and pelvic floor connective tissues, areas that are often weakened in women, especially those with stress urinary incontinence. Increasing Blood Flow These wavelengths also increase nitric oxide production, causing vasodilation and enhanced blood flow. Better circulation results in improved oxygen and nutrient delivery to tissues, supporting healing and muscle function, which are both critical for proper bladder functioning. Blood flow may also increase through the synthesis of new blood vessels, a process called angiogenesis. Modulating Nerves & Pain Pathways In some types of incontinence, nerve signaling may be disrupted and pain pathways activated. Red and near-infrared light may modulate nerve activity and reduce local inflammation, which may help to reduce overactive pain or urgency signals from the bladder and pelvic floor. Supporting the Microbiome An often-overlooked component of pelvic health is the vaginal microbiome. Dysbiosis, or microbial imbalance, can increase susceptibility to infections, inflammation, and irritation. Blue light has been shown to reduce pathogens like Candida, while red light may support beneficial bacteria like Lactobacillus which is important for microbiome health. Disruptions in the microbiome are a risk factor for urinary tract infections, which are a risk factor for incontinence. The Role of Vibration Therapy Vibration therapy offers a second therapeutic modality, especially valuable for activating and strengthening pelvic floor muscles, increasing circulation, and even reducing pain. The Fringe Pelvic Wand provides four levels of mechanical vibration, from gentle (10 Hz) to strength-building (120 Hz). Research shows: Low-frequency vibration (10 or 50 Hz): Helps relax tight pelvic floor muscles, improve proprioception, and increase blood flow High-frequency vibration (90 or 120 Hz): Stimulates reflexive contractions via the pudendal nerve, strengthening pelvic floor muscles in women who struggle with voluntary control How may vibration therapy help with urinary incontinence? Improving Tissue Strength & Integrity Vibration therapy, especially low intensity vibration, may have many effects on cells associated with the structural integrity of the female pelvis, including collagen and muscle. Stronger pelvic floor muscles are associated with reduced urinary incontinence. Increasing Blood Flow Vibration therapy may also increase blood flow, which may help to deliver oxygen and nutrients to the tissues of the pelvis and improve functioning of the bladder and pelvic floor muscles. Modulating Pain Signals Pain signals from the pelvis/bladder may be modulated by vibration therapy, including neuropathic pain, low back pain, and muscle pain. Urinary incontinence is associated with pain in conditions including interstitial cystitis/bladder pain syndrome, vulvodynia, pelvic floor myofascial pain syndrome, and neurogenic bladder disorders like Multiple Sclerosis. Regulating Muscle Tone Balanced pelvic floor muscles with proper tone are essential for proper urinary continence. Vibration therapy may help both to decrease spasticity in muscles that are overactive, as well as improve voluntary muscle contraction, such as those of the pelvic floor, which are poorly controlled in between 30 and 50% of women. The Fringe Pelvic Wand: Dual Therapy for Urinary Incontinence The Fringe Pelvic Wand brings together red, near infrared, and blue light therapy with a range of customizable vibration modes from low to high in one comfortable, easy-to-use device. It was designed to meet a broad spectrum of pelvic health needs: + Light Therapy Specs Wavelengths: 630 nm (red), 830 nm (near infrared), 415 nm (blue) Intensity: 20–40 mW/cm² (adjustable to 50%) Built-in Timer: 10-minute automatic shut-off Modes: Mode 1: Red + Near Infrared Light (deep tissue healing) Mode 2: Blue light only (antimicrobial support) Mode 3: Red only (gentle tissue support for heat/light-sensitive users) + Vibration Therapy Specs Low amplitude, rapid acceleration Built-in Timer: 10-minute automatic shut-off Modes: Mode 1: 10Hz Mode 2: 50Hz Mode 3: 90Hz Mode 4: 120Hz This level of control allows you to personalize therapy sessions to your unique needs, including calming inflammation, strengthening muscles, balancing microbes, or all of the above. How to Use the Fringe Wand for Urinary Incontinence Here's a suggested routine to start with Pelvic Light & Vibration Therapy Safety Light and vibration therapies are well-established as safe, but here are a few precautions: Avoid use if you have known light sensitivity, or are on medications that increase sensitivity to light Don’t use on open wounds Only use water-based lubricants (oil-based can damage the silicone wand material) Check with your provider before use if you're pregnant A New Era of At-Home Pelvic Health Urinary incontinence is a highly prevalent condition that impacts millions of women, yet effective, accessible, and non-invasive treatment options remain limited. The growing body of scientific research surrounding light therapy and vibration therapy offers compelling evidence that these modalities may play a valuable role in supporting pelvic tissue health, improving muscle tone, modulating nerve activity, and restoring microbial balance, all of which are relevant to the underlying causes of incontinence. The Fringe Pelvic Wand was designed with these mechanisms in mind. It provides a multi-modal therapeutic approach that is grounded in emerging science, integrating red, near infrared, and blue light with adjustable vibration frequencies to support the complex structures and functions of the female pelvic floor. Whether used on its own or as a complement to pelvic floor physical therapy, the Fringe Pelvic Wand offers a novel, at-home tool for women seeking to improve urinary continence, restore comfort, and support long-term pelvic health. As with any health intervention, individual responses may vary, and we encourage women to consult with their healthcare providers when integrating new therapies into their wellness routines.

Deconstructing Red Light Therapy Intensity: Why MORE Isn’t Always BETTER!
Red Light Therapy Intensity: Why Higher Power Isn’t Always Better for Results “High intensity, medical grade Red Light Therapy”. This is a statement that is often made about Red Light Therapy devices, implying that to see real therapeutic benefits, that a device must be really powerful. But is this actually true? What does the scientific evidence say about high intensity Red Light Therapy devices? Let’s dig into the research. But first, we need to define what light “intensity” is. Light intensity (also known as power density) describes the amount of light being delivered by a device. Also sometimes called irradiance, it’s usually measured in units called mW/cm2. Intensity is related to power, which is the rate at which energy is delivered, measured in Watts (W). If we look at that energy per square cm of exposure site, we get W/cm2, or mW/cm2 – our intensity. So, intensity is the amount of energy from a device at any given moment, and if we consider that as a function of time of exposure, we get the energy density (measured in J/cm2), which is the total energy delivered over time. This combination of intensity with exposure time is also referred to as the “dose” of light delivered by the treatment. Let’s dig into the assumption that higher powered devices are required to derive benefit by exploring five lines of evidence. 1. Where did the idea that high intensity Red Light Therapy is required for therapeutic benefit come from? This idea comes from the fact that for decades, virtually all research and applications of photobiomodulation were done with lasers, which are high intensity devices. Research into Red Light Therapy began in the 1960’s, and lasers dominated the field until around the early 2000’s, when LED’s (light emitting diodes) began to be studied. The scientific literature is comprised of around 85% studies using lasers as light sources, with the rest using LED’s. Companies making higher powered devices are often trying to get close to the power of lasers, citing laser research that shows benefits. However, hundreds of studies have now shown that LED Red Light Therapy yields many benefits, such as reducing pain and inflammation. And, LED’s have four important advantages over lasers: (1) they’re safer, (2) they’re cheaper, (3) they can be easily used at home, and (4) LED’s can cover a greater area of the body allowing more tissue to receive light. Given this, an important question for researchers in the field to address was whether the benefits of Red Light Therapy were specific to something about laser light, or whether those benefits could be replicated using LED’s. In 2018, an analysis that reviewed the comparative evidence of lasers versus LED’s concluded that “most of these comparisons provisionally suggest that lasers could indeed be replaced with LED’s without significant worsening of the results.” This is despite major differences in power outputs, which demonstrates that high intensity lasers are not required for therapeutic benefits. 2. Does the research on Red Light Therapy demonstrate that a certain intensity range is needed to observe therapeutic benefits? There is an excellent comprehensive database online of published photobiomodulation research studies that describes the details of thousands of Red Light Therapy studies. We can look at this database to compare the intensity (power) of studies relative to their results, and to see if there are clear trends, such as a requirement for high intensity/power to yield benefits. Most studies using LED’s have an intensity between 10 and 100mW/cm2 and are most commonly between 10 and 50mW/cm2. For lasers, the intensity is much higher, based on the different characteristics of the light produced. Positive results spanning a wide range of outcomes are observed, and there are no clear trends related to light intensity. Some studies use extremely low intensity LED lights, some use higher intensity LED lights, and some use high intensity lasers. Although studies of certain light intensities are sometimes used to support specific products, when you look at the totality of the research, the main conclusion that can be drawn is that exposure to red and/or near infrared light across a wide range of light characteristics, including intensity, yields biological benefits. 3. Can devices with different intensities be used to deliver the same “dose” of light? Theoretically, the time variable can be manipulated when using devices with different intensities to deliver the same “dose” of light. Mathematical calculations show that higher intensity devices used for shorter periods of time can deliver a comparable dose of light to lower intensity devices used for longer periods of time. However, some research has demonstrated that our bodies don’t seem to absorb photons the same way when they are delivered at a high intensity, suggesting that “dose” may not simply be a mathematical calculation of intensity and time. For example, a recent comprehensive review of studies of red light therapy for the brain found that “NIR light with low-power density (15–30 mW/cm2) is a more effective intervention than that with high-power density (40–90 mW/cm2)." 4. If low, moderate, and high intensity devices have been shown to deliver therapeutic benefits, are there reasons for preferring low or moderate intensity rather than high? Yes, there are reasons to prefer low to moderate intensity devices as compared to high. For example, high intensity light can increase oxidative stress, which is harmful to biological health. When wounds are treated with low/moderate intensity red light therapy, markers of oxidative stress initially increase and then decrease dramatically as healing progresses. However, when wounds are treated with high intensity red light therapy, oxidative stress remains high. Similarly, levels of antioxidant enzyme activity (which reduces oxidative stress) increase with low/moderate intensity red light therapy but not with high intensity light. This suggests that low/moderate intensity Red Light Therapy reduces oxidative stress, while high intensity Red Light Therapy may cause it to increase. High intensity light also carries a risk of heating tissues and causing thermal damage. 5. Are there biological reasons to expect that there could be an upper limit to Red Light Therapy intensity when it comes to therapeutic benefits? Yes! Researchers have carefully studied the biological effects of Red Light Therapy and have clearly concluded that “dose” matters. If the dose is too low, there is no benefit; similarly, if it is too high, there is also no benefit – and there is the potential for harm. This is called a biphasic dose response, also known as the Arndt Shulz law. Picture this as an inverted U curve. If the dose is too low or too high, there will be minimal response, but there is a relatively wide range of doses in the middle range that are beneficial. As described by Dr. Michael Hamblin, “It has been consistently found that when the dose of is increased a maximum response is reached at some value, and if the dose in increased beyond that maximal value, the response diminishes, disappears and it is even possible that negative or inhibitory effects are produced at very high fluences.” Because “dose” is a function of intensity and time, using high intensity devices for too long can easily yield a dose of light that will not be beneficial, and may even be harmful. These five lines of evidence clearly illustrate that the assumption that high intensity devices are needed to achieve benefit is not accurate. It is the dose that creates the benefit – and dose is a function of intensity and time. While it may be appealing to use a higher intensity light to get the treatment done faster, this carries risks including thermal damage due to heating tissues, as well as a risk of causing oxidative stress. The tendency when using a high intensity device – which would require a treatment time of only a few minutes (or even less) – is to overdo it. For at-home devices, low to moderate intensities leave more wiggle room in terms of both safety and benefits. Fringe Red Light Therapy Intensity Fringe Red Light Therapy products were designed to deliver light at an intensity of 20-40mW/cm2, which is the approximate intensity of the sun. This has been described as the “sweet spot” between higher intensities, which can have harmful effects, and lower intensities, which will have no effect at all. Although there are no clear distinctions between low, moderate, and high intensity devices, the intensity of Fringe Red Light Therapy devices would most appropriately be termed as low/moderate and stands in contrast to many devices on the market, which are 100mW/cm2 or even higher. At this intensity, our products can safely be used for treatment periods between 10 and 30 minutes, and our products are programmed with built-in timers to deliver a safe and effective dose of light. We verify the intensity of our products using third party testing, which is important because independent research has found that many commercial home-based Red Light Therapy products do not deliver light as advertised. Take Home Points The idea that high intensity Red Light Therapy devices are needed for therapeutic benefits originated from decades of research using high intensity lasers; however, subsequent research has demonstrated that lower intensity LED powered devices can yield comparable results. An analysis of the totality of published Red Light Therapy research (using both lasers and LED’s) shows that benefits can be seen when using devices that span a very wide range of intensity, from low to high. This is consistent with research that shows the effective “dose” of Red Light Therapy follows a U-shaped curve, with benefits spanning a wide range but which has a lower and upper limit. The “dose” of light is determined by its intensity and the treatment time, although research has shown that delivering light quickly using a high intensity device may not be as effective as delivering it more slowly using a lower intensity device, suggesting that the “dose” is not the only factor that determines benefits. High intensity light can increase oxidative stress and the risk of thermal damage, so care must be taken when using high powered devices to limit treatment times, which can be difficult to do when using at-home devices. The Verdict? Research evidence does not support the claim that high intensity Red Light Therapy devices are required for therapeutic benefits. Using low to moderate intensity devices yields results that are comparable to using high intensity devices, with some research even demonstrating greater efficacy. Low to moderate intensity devices also have the advantage of greater safety and can be safely used at home as part of a regular wellness regime. Choose a device that suits your needs and preferred treatment conditions, and which delivers both red and near infrared light at an appropriate intensity. Combine red light therapy with an anti-inflammatory diet and supplements, regular exercise, stress management, and good sleep hygiene for best results.

Red Light Therapy & Traumatic Brain Injury
What is Traumatic Brain Injury? Traumatic Brain Injury (TBI) occurs when the brain is damaged by an external force, like an impact, blast, or rapid acceleration/deceleration. Common causes of TBI include falls, sports injuries, vehicle accidents, and physical assaults. Damage from TBI’s can lead to long-lasting and even permanent impairment of brain function. TBI’s are common injuries in the US, with approximately 1.5 million Americans experiencing a TBI annually. TBI is considered an umbrella term that refers to any brain injury caused by an external source. TBI’s can be categorized by severity, ranging from mild to severe, and have unique characteristics: Mild TBI – Causes temporary confusion and headache. Moderate TBI – Causes prolonged confusion and cognitive impairment. Severe TBI – Causes significant cognitive deficits and long-term complications. TBI’s can also be categorized by timeframe, including both acute (short-term) and chronic (long-term) effects. The acute phase last from hours to weeks, while the chronic phase lasts from weeks to years, depending on the severity of the TBI. Two TBI-related terms that may be familiar to people are concussions and Chronic Traumatic Encephalopathy (CTE). Concussions are a type of mild TBI, and although symptoms usually resolve within days to weeks, they can still have long-term effects, especially with multiple incidents. One potential long-term consequence of repeated concussions is CTE, a progressive neurodegenerative disease believed to be caused by repeated head injuries, including multiple mild TBIs. Treatment for TBI varies greatly depending on the severity of the injury. In general, it involves stabilization, symptom management, and rehabilitation. The primary goal of treatment during the acute phase is to protect brain tissue and focuses on cognitive rest and addressing symptoms. In the chronic phase, the primary goal of treatment is to restore cognitive, motor, and emotional function. Emerging treatments such as Red Light Therapy may be beneficial in supporting the brain during both the acute and Shop Red Light Therapy Head Wrap How does TBI affect the Brain Before we consider how Red Light Therapy may be used to support brain health following TBI, let’s take a closer look at the three major pathological processes that occur in the brain during this type of injury. Neuroinflammation: TBI causes neuroinflammation, which occurs in the hours to days following the injury. Neuroinflammation is inflammation of the brain, which can be helpful in the short term but is harmful when prolonged, leading to chronic neurodegeneration. Excess neuroinflammation is linked to brain fog, mood disorders, and an increased risk of neurodegenerative diseases such as CTE. Oxidative stress: Following a TBI, the brain produces excessive amount of reactive oxygen species (ROS), which can lead to oxidative stress. Oxidative stress can overwhelm our antioxidant defenses and cause damage to cells in the brain, worsening brain injury. Impaired brain energy metabolism: TBI impairs brain energy metabolism, particularly the ability of the brain to use glucose, which leads to a metabolic crisis where neurons are deprived of energy. After an initial phase of excessive glucose use, there is a decrease in glucose availability that can last from days to weeks, which makes neurons more vulnerable to damage and impairs healing. These three factors interact and include many overlapping molecules. For example, both neuroinflammation and impaired brain energy metabolism can lead to an increase in ROS production, further worsening oxidative stress. Similarly, impaired energy metabolism exacerbates neuroinflammation. This creates a self-perpetuating cycle of damage, which is why TBI recovery can be slow and why some people experience persistent symptoms for weeks, months, or even years following the injury. How does Red Light Therapy support brain function? Red Light Therapy is a promising tool for supporting the brain during TBI because it targets all three foundational brain pathologies, including neuroinflammation, oxidative stress, and impaired brain energy metabolism. Using both red and near infrared light (especially near infrared, which has deeper penetration), Red Light Therapy delivers wavelengths that interact with light sensitive molecules inside brain cells. Here's how Red Light Therapy affects neuroinflammation, oxidative stress, and brain energy metabolism: Neuroinflammation: Red and near infrared light wavelengths have anti-inflammatory effects, and unlike anti-inflammatory medications (such as NSAID’s), do not cause side effects. Studies have found that light therapy affects levels of many molecules involved in inflammation, including ROS, reactive nitrogen species, and prostaglandins. Red and near infrared light therapy have specifically shown to reduce neuroinflammation. Oxidative stress: 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 ROS that cause oxidative stress when present in high amounts. Light therapy has been shown to modulate oxidative stress and ROS production. Impaired brain energy metabolism: Through its impact on mitochondria, light also affects metabolism. In addition to regulating ROS production, mitochondria also make ATP, which is the energy currency of the cell, via a chain of molecules that includes cytochrome c oxidase. Cytochrome c oxidase is activated by both red and near infrared light, which increases ATP synthesis and provides more energy to brain cells. As well, there are additional effects of Red Light Therapy in the brain that may help to support healing from TBI. This includes increasing brain blood flow, supporting brain adaptability, and regulating neuron cell death. Collectively, there are many ways in which Red Light Therapy may be used therapeutically in TBI, and these have been explored in several clinical and pre-clinical studies of both acute and chronic TBI. Is there evidence to support the use of Red Light Therapy in TBI? Yes! Red Light Therapy has been investigated in several studies of TBI using a range of different experimental approaches. These studies can be broken down by timeframe into both acute and chronic TBI, as well as by study type, including clinical (using humans as subjects) and pre-clinical (using animals as subjects). Acute TBI The acute phase of TBI immediately follows the onset of injury. Unfortunately, this creates some challenge in coordinating and executing research studies, since it is difficult to recruit human subjects into a research study who have just experienced a head injury. As a result, most of the research in this TBI phase has been done using animals given a head injury in a controlled environment. In a 2023 systematic review of 17 animal studies that used Red Light Therapy immediately post-TBI, it was found that early light therapy intervention could improve neurological outcomes and reduce the size of trauma-associated brain lesions. Optimal results were associated with both red and near infrared light, initiation within 4 hours post-injury, and up to three daily treatments. One human study was included in the review of Red Light Therapy for acute TBI, which suggested safety and feasibility, but treatment efficacy could not be determined. Chronic TBI Many more human studies have explored the use of Red Light Therapy in the chronic phase of TBI, which occurs weeks to months after the initial trauma. In a 2024 review of 16 human studies, overall improvements in neuropsychological outcomes and increased cerebral blood flow following transcranial PBM were observed. Here are some highlights of the clinical research findings: How can I use Red Light Therapy in TBI? 2019 study of 12 military veterans with chronic TBI lasting more than 18 months – Following six weeks of application of both red and near infrared light to the head using LED lights, neuropsychological scores and brain blood flow were improved. 2020 case report of 23-year professional hockey player with a history of concussions, and symptoms of headaches, mild anxiety, and difficulty concentrating - Following 8 weeks of application of near infrared light to the head using LED lights, many positive findings were observed, including increased brain volume, improved brain connectivity, increased brain blood flow, and improved neuropsychological test scores. 2023 study of four retired professional football players with suspected CTE – Following application of near infrared light to the head using LED lights three times per week for six weeks, a wide range of improvements were noted, including improved sleep, reduced depression, decreased PTSD, and decreased pain. Analysis of brain function showed several improvements. Collectively, research looking at the use of Red Light Therapy to support healing from TBI has yielded positive outcomes, both subjective (such as improved mood and decreased pain), and objective (such as increased brain volume and blood flow). There is stronger support for the use of Red Light Therapy in chronic TBI, but pre-clinical evidence supports the potential for benefit during the acute phase of injury. TBI Recovery Managing TBI involves a combination of stabilization, symptom relief, and rehabilitation, each playing a crucial role in recovery. Red Light Therapy is a safe and effective tool that can support healing throughout all three stages. While it can be conveniently done at home using a Red Light Therapy device, professional supervision is recommended during the acute phase to ensure safe and effective application. When exploring the range of available options, here are four things to consider: Light wavelength – The wavelength of light determines its color, with red light in the range of 620-700nm and near infrared light in the range of 700-1100nm. Although near infrared has been used most often to support healing from TBI, some studies have also found benefit from red light. Light with wavelengths between 600 and 1300nm have been found to penetrate maximally into the brain. So, look for products that provide both RL and NIRL in combination. Light intensity - Light intensity refers to the amount of light being delivered by a device, also referred to as power density. Studies of Red Light Therapy and TBI have used a range of intensities, from 10-100mW/cm2, and there is no clear indication that a particular intensity must be used. Devices across a range of intensities may provide benefit, and consumers aren’t limited to a specific intensity range. Type of device - Your personal level of comfort with a device is important. If it isn’t easy to use, and if it doesn’t feel good on your body, you probably won’t use it consistently. Many consumers find the most convenient devices to use are wireless, with a rechargeable battery. It is also important to use a device that can be adjusted to fit snugly on the head. Think about your personal preferences and choose a device that fits your criteria. Light Source - Light therapy is administered using either laser or LED lights. While early light therapy research was done using lasers, LED lights have become much more popular over the last decade. For at home use, look for a device that uses LED lights as safe and affordable option. The next step after selecting a Red Light Therapy device is to determine the treatment protocol. During the acute phase of TBI, it is recommended to consult with your health care provider to get their professional guidance regarding the most appropriate protocol for your case. During the chronic phase of TBI, support from a health care professional is also recommended, but people may be more independent during this period. Based on available clinical research, 10-40 minute treatment sessions, 3 to 5 times a week, are recommended. Do not exceed more than one session every 24 hours. Conclusion Red Light Therapy is a safe, affordable, and highly effective tool for supporting at-home recovery from TBI. By targeting the three core drivers of brain injury—oxidative stress, impaired metabolism, and neuroinflammation—it offers a scientifically backed approach to healing. Research suggests benefits across all stages of TBI, from the critical early hours to years post-injury. When choosing a device, look for red and near-infrared LED technology that aligns with your needs for comfort and convenience, empowering you to take an active role in your recovery.

Incandescent vs LED Lights in Red Light Therapy
Red Light Therapy has been investigated in thousands of research studies over the last 50 years. Until the early 2000’s, most studies used lasers as the light source, but more recently, LED lights have become popular due to their affordability, safety, and ease of at-home use. LED lights are now widely used in Red Light Therapy devices, including the devices we make at Fringe. Other light sources, such as incandescent lights, are also sometimes promoted for use in Red Light Therapy, but it’s important to recognize that incandescent lights are not equivalent to LED’s when it comes to reaping the well-recognized benefits of this powerful healing modality. In this article, we’ll explore the characteristics of LED and incandescent lights, how the two light types can (and cannot) be used in Red Light Therapy, and what to look for in a Red Light Therapy device. Comparison of LED and Incandescent Lights LED lights have many important characteristics that are superior to incandescent lights, including: Characteristics LED Incandescent Energy Efficiency 80-90% more efficient than incandescent, as most energy is converted to light Very inefficient – 90 to 95% of energy is lost as heat, and only 5 to 10% is converted to light Lifespan 25,000 to 50,000 hours (10 to 25x longer than incandescent) 1,000 to 2,000 hours (needs frequent replacement Heat Output Minimal heat emission, stays cool to the touch High heat emission, can become too hot to touch Long-Term Cost Lower long-term cost due to energy savings and longer lifespan Higher long-term cost due to frequent replacements and high energy use Durability Shock-resistant, does not break easily Fragile, glass can break easily Environmental Impact Eco-friendly, no toxic materials, low energy consumption Higher energy use, shorter lifespan, increases waste There are also some areas where LED’s can be inferior to incandescent lights, including: Characteristics LED Incandescent Flicker Potential Some LEDs flicker which can cause eye strain No flicker; provides continuous, steady light EMF Emission May emit higher EMF’s due to electronic drivers Minimal EMF emission, since it does not use electronic drivers Blue Light Exposure Can be quite high Low, more natural warm light However, NONE of these characteristics are necessarily an issue with Red Light Therapy devices. Why we don’t NECESSARILY need to be concerned about these limitations (Flicker, EMF, Blue Light Exposure) with Red Light Therapy devices: Many Red Light Therapy devices do not flicker – a reputable company will demonstrate this using third party testing (we do!) EMF emission – it’s absolutely true that a LOT of Red Light Therapy devices emit way too many EMF’s, but they don’t have to. At Fringe, we’ve designed our panels so that the electronic driver is 3 feet away from the panel, so there is almost no EMF emission from the panel itself. Our wraps are battery powered; batteries create energy through chemical reactions, which generate negligeable EMF’s. Blue Light Exposure – Red Light Therapy devices contain red and near infrared LED’s, which don’t emit blue light (of course, blue light LED’s are also an option…!) What about Blue Light Therapy using LED’s? Isn’t blue light from LED lights harmful? This is true but isn’t the whole story. Blue light from devices like ipads, phones, etc. is found in a very narrow spectrum of wavelengths. This is “foreign” to our body, as it is different than the blue light that comes from the sun. In contrast, blue light used in Blue Light Therapy emits a wider spectrum of wavelengths that closely mimics the distribution of blue light in sunlight. This light spectrum has been found to be antimicrobial, which is why it is used for applications like acne. No matter what, though, it’s still important to avoid getting blue light in the eyes. Is light from an incandescent light the same as from an LED? Incandescent lights produce light in a “full spectrum”, including red and near (and also far) infrared light. This is what makes the light from incandescents “warm” in terms of color, and also generates a lot of heat, making them hot to the touch. It’s also why these lights are used for things like heating terrariums. In order to make an incandescent light exclusively red, a red film or coating is placed on the glass that filters out other colors allowing only the red (and sometimes infrared) wavelengths to pass through. The filament inside still produces other colors, but they’re mostly blocked by the coating. LED lights used in Red Light Therapy will produce light in the red (if using red diodes) or near infrared (if using near infrared diodes) spectrums. Many devices include both types of diode, and the type of light is produced by using a semiconductor material that naturally produces red or near infrared light. Red Light Therapy doesn’t use white LED lights like you would find in a house lamp. Red and near infrared light are the same in terms of wavelength no matter what the source. The difference is that incandescent lights produce full spectrum light and then block the other light from being emitted, while LED lights (red or near infrared) emit ONLY the light in that color spectrum. If the red and near infrared light is the same, can incandescent lights be used instead of LED’s in Red Light Therapy? Incandescent lights CAN be used to activate the eye to brain pathway that is responsible for some of the benefits of Red Light Therapy. In this pathway, photoreceptors in the retina are activated and influence the function of the suprachiasmatic nucleus in the brain. This helps regulate the circadian cycle and also has an influence on mood and stress hormones. These lights are great for lighting up a room. Incandescent lights CANNOT be used as easily as LED’s to activate the light to tissue pathway that is responsible for the majority of benefits of Red Light Therapy. In this pathway, light enters through the skin (or other tissue) and activates photoreceptors in cells, such as cytochrome c oxidase in mitochondria. To achieve this benefit, the skin/tissue has to be close (6 inches or less) away from the light source. Because incandescent lights get hot and are fragile, they aren’t a substitute for durable LED’s that don’t generate much heat. Incandescent bulbs also generate scattered light, which doesn’t allow for good skin/tissue penetration. There is limited research showing that under some circumstances, incandescent lights may activate this pathway, but their functional limitations do not make them a substitute for LED’s. Most of the benefits of Red Light Therapy (reduced inflammation, faster tissue healing, reduced oxidative stress) comes from the light to tissue pathway. Incandescent lights do not work to activate this pathway effectively. It’s also important to note that almost none of the benefits of Red Light Therapy that have been observed in thousands of research studies over the last 50 years used incandescent light, with most studies using laser or LED light. How do I know if my Red Light Therapy device is safe to use? Here are some things to look for: Use of red and near infrared light in evidence-based spectrums. Fringe Red Light Therapy devices use red light at 660nm and near infrared light at 850nm, which have been demonstrated in many research studies to be beneficial. No flicker Low to no EMF’s. Low irradiance (this is also called power or intensity. And yup, you want this low. A lot of companies are selling products that are quite high intensity, and this can potentially be harmful). Irradiance in the range of 20-40mW/cm2 mimics the sun, and has been shown in multiple research studies to be both safe and effective. A good company will prove these by sharing analyses done by third party testing. Why choose Fringe Red Light Therapy devices? We use evidence-backed wavelengths of red and near infrared light. Our devices are no flicker and generate low to no EMF’s. We use a safe and effective sun-like intensity of light, at between 20 and 40mW/cm2. All of our products are tested by an independent third party lab, and we share this analysis with our consumers. Our products are created by a team of medical professionals who carefully review and use published scientific evidence to inform how we manufacture. Take home message: Incandescent lights are a great option for lighting up a room, creating a warm and ambient red light that may have benefits related to activation of the eye to brain pathway which helps to regulate the circadian rhythm and mood. Incandescent lights cannot be used as a substitute for LED lights to activate the tissue to cell pathway that is responsible for benefits including reduced inflammation, decreased oxidative stress, and improved tissue healing. Of the thousands of research studies on Red Light Therapy, only a small number used incandescent lights, so their clinical efficacy has not been clearly demonstrated. High-quality Red Light Therapy devices will use both red and near infrared LED lights and will be no flicker, generate low to no EMFS, and deliver light at a sun-like intensity that is both safe and effective for everyone, including kids and pets.
