Research done by #NASA in conjunction with the University of Alabama at Birmingham Hospital has shown that red light technology can successfully reduce symptoms experienced by cancer patients, including painful side effects caused from radiation or #chemotherapy. Using far red/near-infrared light-emitting #diode devices (called High Emissivity Aluminiferous Luminescent Substrate, or HEALS in this case) has been shown to release long wavelength energy in the form of photons that stimulate cells to aid in #healing.
NASA tested whether HEALS could treat oral mucositis in cancer patients, a very common and painful side effect of chemotherapy and radiation, and concluded that 96 percent of patients experienced improvement in pain as a result of the HEALS treatment. Patients received the light therapy by a nurse holding the #WARP75 device, which is roughly the size of an adult human hand. The WARP device was held close to the patient’s face and neck for only 88 seconds daily for 14 days. Researchers stated, “The HEALS device was well tolerated with no adverse affects to bone marrow and #stemCell transplant patients….The #HEALS device can provide a cost-effective therapy since the device itself is less expensive than one day at the hospital.” #LightTheraphy

The Warp 75 is an LED device designed by NASA, currently used to reduce the painful side effects resulting from chemotherapy and radiation treatment in bone marrow and stem cell transplant patients. It was initially used to grow plants in extraterrestrial environments. Glowing red light from High Emissivity Aluminiferous Luminescent Substrate, or HEALS technology has been proven to aid in the healing of human wounds, burns, diabetic skin ulcers and oral mucositis.The Warp 75 is also used for the treatment of chronic pain, including the temporary relief of minor muscle and joint pain, arthritis, muscle spasms, and stiffness, by promoting relaxation of muscle tissue and temporarily increasing local blood circulation. It uses 670 nm LEDs thus the bright red colour and can produce 5 Joules/cm2 every 88 seconds.
Glowing red light from High Emissivity Aluminiferous Luminescent Substrate, or HEALS technology -- previously used to grow plants for space experiments -- also has been proven to aid in the healing of human wounds, burns, diabetic skin ulcers and oral mucositis -- a common and extremely painful side effect of chemotherapy and radiation treatment. NASA has partnered with Quantum Devices Inc. (QDI), of Barneveld Wis., to develop the WARP 75 light delivery system device for wound healing. A two-year clinical trial using the WARP 75 device on cancer patients undergoing bone marrow or stem cell transplants, concluded that there was a 96-percent chance that the improvement in pain relief of those in the high-risk patient group was the result of the HEALS treatment. The clinical trial was funded by NASA's Innovative Partnerships Program at the Marshall Space Flight Center in Huntsville, Ala. The NASA program works with industry and commercial partners to spinoff space technology and adapt it for new, innovative applications.

Near infrared light therapy is an every-day term for the science of photobiomodulation. It uses invisible, near infrared wavelengths between 700 and 1200 nm to deliver energy to the cells, stimulating healing and relieving pain. Infrared light therapy has been proven effective by hundreds of studies all over the globe, is 100% natural and has no known adverse side effects.
Near infrared light therapy is essentially the same as red light therapy, except infrared energy is invisible, and it penetrates the body deeper than red, reaching deep into soft tissues, muscles, joints, and bone.
Near infrared light therapy is where light therapy gets serious. The combination of red light therapy with near infrared energy is being researched for amazing things such as the reversal of traumatic brain injury, stopping and healing the debilitating effects of stroke and heart attack, and the regeneration of damaged nerves and severed spinal cords.
While all of that is unfortunately still years away from common practice, the power of near infrared light therapy has already been FDA approved and is available in-home for the relief of chronic pain. As with red light therapy, near infrared light therapy does not mask the symptoms of pain, it encourages the healing of the actual cause of the pain and so, in many cases, after a course of treatment with infrared light, the pain is gone for good.
The Wavelengths of Near Infrared Light Therapy
Infrared light immediately follows red light on the electromagnetic spectrum. Infrared (IR) light energy is broken down into three groups:
Near Infrared, also called infrared A (IR-A). Near IR spans wavelengths 760 to 1,400 nm. Most home therapy devices use these wavelengths.
Mid Infrared, also called infrared B (IR-B) – These wavelengths are used in many household electronic devices such as remote controls.
Far Infrared, or IR-C– also known as long wave infrared , thermal infrared (thermal-IR). This is the largest part of the IR spectrum, used in infrared saunas.
Examples of the wavelengths used in near infrared light therapy.
Near-infrared LEDs will appear unlit because their energy is not visible to the human eye. However, they are just as powerful as the red you can see and actually penetrate the body deeper.
Effective wavelengths of near infrared light therapy include 700 nm to 1400 nm. The whole range of wavelengths have the same healing and therapeutic effect, the big difference is this: the longer the wavelength, the deeper it penetrates into the body. So, for example, for applications effecting the surface of the skin, red light therapy (620nm-700nm) would be adequate. For the healing of deep wounds or the relief of deep muscle and joint pain, the longer wavelengths of near infrared are more beneficial. 850nm and 980 nm are common.
How Does it Work?
Near infrared light therapy works exactly the same way red light therapy works. Visible red and invisible near infrared energy are absorbed by photoreceptors in each cell. Once absorbed, the light energy kicks off a whole series of metabolic events, stimulating the body’s natural processes on a cellular level. There is an increase in blood flow, allowing the parts of the body to receive the oxygen and nutrients they need in order to function more effectively. Regeneration is stimulated. Inflammation and pain are reduced.
What Kind of Light Do You Need?
As with red light therapy, the light source does not matter. Effective near infrared light therapy can come from a low level laser, high power LED, and array of low power LEDs, incandescent, fluorescent or other light source, as long as the proper wavelengths are emitted.
Although red infrared light therapy is safe, one should follow the same precautions as for red light therapy before beginning treatment.
2. Red light therapy (RLT) is a controversial therapeutic technique that uses red low-level wavelengths of light to treat skin issues, such as wrinkles, scars, and persistent wounds, among other conditions.
In the early 1990s, RLT was used by scientists to help grow plants in space. The scientists found that the intense light from red light-emitting diodes (LEDs) helped promote growth and photosynthesis of plant cells.
Red light was then studied for its potential application in medicine, more specifically to find out if RLT could increase energy inside human cells. The researchers hoped that RLT could be an effective way to treat the muscle atrophy, slow wound healing, and bone density issues caused by weightlessness during space travel.
You may have heard of red light therapy (RLT) by its other names, which include:
photobiomodulation (PBM)
low level light therapy (LLLT)
soft laser therapy
cold laser therapy
biostimulation
photonic stimulation
low-power laser therapy (LPLT)
When RLT is used with photosensitizing medications, it’s referred to as photodynamic therapy. In this type of therapy, the light only serves as an activating agent for the medication.
There are many different types of red light therapy. Red light beds found at salons are said to help reduce cosmetic skin issues, like stretch marks and wrinkles. Red light therapy used in an medical office setting may be used to treat more serious conditions, like psoriasis, slow-healing wounds, and even the side effects of chemotherapy.
While there’s a fair amount of evidence to show that RLT may be a promising treatment for certain conditions, there’s still a lot to learn about how it works, too.
How does red light therapy work?
Red light is thought to work by producing a biochemical effect in cells that strengthens the mitochondria. The mitochondria are the powerhouse of the cell — it’s where the cell’s energy is created. The energy-carrying molecule found in the cells of all living things is called ATP (adenosine triphosphate).
By increasing the function of the mitochondria using RLT, a cell can make more ATP. With more energy, cells can function more efficiently, rejuvenate themselves, and repair damage.
RLT is different from laser or intense pulsed light (IPL) therapies because it doesn’t cause damage to the skin surface. Laser and pulsed light therapies work by causing controlled damage to the outer layer of the skin, which then induces tissue repair. RLT bypasses this harsh step by directly stimulating regeneration of the skin. The light emitted by RLT penetrates roughly 5 millimeters below the skin’s surface.
How is red light therapy used?
Ever since the initial experiments in space, there have been hundreds of clinical studies and thousands of laboratory studies conducted to determine if RLT has medical benefits.
Many studies have had promising results, but the benefits of red light therapy are still a source of controversy. The Centers for Medicare and Medicaid Services (CMS), for example, has determined that there isn’t enough evidence to show that these devices are better than currently existing treatments for treating wounds, ulcers, and pain.
Additional clinical research is needed to prove that RLT is effective. At the moment, however, there’s some evidence to suggest that RLT may have the following benefits:
promotes wound healing and tissue repair
improves hair growth in people with androgenic alopecia
help for the short-term treatment of carpal tunnel syndrome
stimulates healing of slow-healing wounds, like diabetic foot ulcers
reduces psoriasis lesions
aids with short-term relief of pain and morning stiffness in people with rheumatoid arthritis
reduces some of the side effects of cancer treatments, including oral mucositis
improves skin complexion and builds collagen to diminish wrinkles
helps to mend sun damage
prevents recurring cold sores from herpes simplex virus infections
improves the health of joints in people with degenerative osteoarthritis of the knee
helps diminish scars
relieves pain and inflammation in people with pain in the Achilles tendons
Currently, RLT isn’t endorsed or covered by insurance companies for these conditions due to lack of sufficient evidence. Although, a few insurance companies now cover the use of RLT to prevent oral mucositis during cancer treatment.
But does red light therapy really work?
While the internet is often abuzz with news about miracle treatments for just about every health condition, red light therapy certainly isn’t a cure-all for everything. RLT is considered experimental for most conditions.
There’s limited-to-no evidence showing that red light therapy does the following:
treats depression, seasonal affective disorder, and postpartum depression
activates the lymphatic system to help “detoxify” the body
boosts the immune system
reduces cellulite
aids in weight loss
treats back or neck pain
fights periodontitis and dental infections
cures acne
treats cancer
It’s important to note that when RLT is used with cancer treatments, the light is only used to activate another medication. Other light therapies have been used to help with some of the conditions above. For instance, studies have found that white light therapy is more effective at treating symptoms of depression than red light. Blue light therapy is more commonly used for acne, with limited effectiveness.
Through emitting red, low-light wavelengths through the skin, red light therapy helps naturally jump-start the process of tissue recovery and other forms of rejuvenation through increased blood flow, collagen stimulation and more. 2010 marked the 50th anniversary for medical laser treatments like red light therapy, providing a host of evidence on their benefits. (1)
If you’ve never heard of red light therapy before, you might already be familiar with other terms that are used to describe this treatment, such as low level laser therapy (LLLT), biostimulation (BIOS), photonic stimulation or simply light box therapy. Red light is considered “low level” because it works at an energy density that’s low compared to other forms of laser therapies.
Red light therapies have come a long way, but do they really work? Clinical studies show that, yes, red lightbox therapies have certain healing capabilities and medical applications thanks to the way they positively affect the human endocrine and immune systems. LLLT is now FDA-approved for treating conditions like chronic joint pain and slow-to-heal wounds. In the near future, we can expect approval for many more conditions thanks to red light benefits, such as increased immunity, tissue repair, anti-aging effects, improved joints and more.
What Is Red Light Therapy?
Red light therapy involves having low-power red light wavelengths emitted directly through the skin, although this process cannot be felt and isn’t painful because it doesn’t produce any heat. Red light can be absorbed into the skin to a depth of about eight to 10 millimeters, at which point it has positive effects on cellular energy and multiple nervous system and metabolic processes.
Red light therapy has shown promise for treating symptoms of joint pain or osteoarthritis due to aging, those caused by cancer treatments like chemotherapy or radiation, hair loss, wounds or incisions, acne, wrinkles and skin discoloration, chronic muscular pain, neurological damage, and tissue damage (often at the root of tears, sprains or pulls). As you’ll learn, even seeing the color red is physically stimulating, primes our senses and gets our blood pumping, so imagine what red light penetrating right into your body can do.
Although there is still controversy over this treatment and more research needed, according to the company Light Therapy Options LLC, there are virtually “no known adverse side effects” of red light therapy treatments, rather a growing list of many anti-aging benefits. (2)
Some of the ways that red light wavelengths work are: (3)
Increasing energy levels by promoting release of ATP from cells’ mitochondria (4)
Stimulating DNA/RNA synthesis (5)
Activating the lymphatic system, an important part of our immune system that helps carry waste out of the body
Increasing blood flow/circulation, thereby helping bring more oxygen and nutrients to our cells and tissues
Forming new capillaries (small blood vessels)
Improving natural production of collagen and fibroblasts, important for things like skin, joint and digestive health
Repairing and restoring damaged soft connective tissue
Stimulating or decreasing inflammation, which helps control our natural healing capabilities
Lowering effects of oxidative stress/free radical damage, which is associated with many effects of aging
5 Benefits of Red Light Therapy
1. Increased Immunity and Reduced Side Effects of Cancer Treatments
Research done by NASA in conjunction with the University of Alabama at Birmingham Hospital has shown that red light technology can successfully reduce symptoms experienced by cancer patients, including painful side effects caused from radiation or chemotherapy. Using far red/near-infrared light-emitting diode devices (called High Emissivity Aluminiferous Luminescent Substrate, or HEALS in this case) has been shown to release long wavelength energy in the form of photons that stimulate cells to aid in healing.
NASA tested whether HEALS could treat oral mucositis in cancer patients, a very common and painful side effect of chemotherapy and radiation, and concluded that 96 percent of patients experienced improvement in pain as a result of the HEALS treatment. Patients received the light therapy by a nurse holding the WARP 75 device, which is roughly the size of an adult human hand. The WARP device was held close to the patient’s face and neck for only 88 seconds daily for 14 days. Researchers stated, “The HEALS device was well tolerated with no adverse affects to bone marrow and stem cell transplant patients….The HEALS device can provide a cost-effective therapy since the device itself is less expensive than one day at the hospital.” (6)
Similar HEALS technology is also now being utilized for the treatment of pediatric brain tumors, slow-healing wounds or infections, diabetic skin ulcers, and serious burns.
2. Wound Healing and Tissue Repair
Light in the spectral range of 600 to 1,300 nanometers has been found to be useful for promoting wound healing, tissue repair and skin rejuvenation, although it does this through a different mechanism of action compared to many other laser resurfacing treatments. Most laser therapies used in dermatology offices use intense pulsed light to promote skin rejuvenation by inducing secondary tissue repair. In other words, they cause intentional damage to either the epidermis or the dermis of the skin in order to trigger inflammation, followed by healing.
Red light therapy actually bypasses this initial destructive step and instead directly stimulates regenerative processes in the skin through increased cellular proliferation, migration and adhesion. Red light therapy has been shown to positively affect skin cells through regeneration of fibroblasts, keratinocytes and modulation of immune cells (including mast cells, neutrophils and macrophages) all found within skin tissue.
3. Anti-Aging Effects for Skin and Hair Loss
One use of red light laser therapy that’s growing in popularity is reversing signs of aging on the skin (i.e, wrinkles and fine lines). Results from a 2014 study published in Photomedicine and Laser Surgery demonstrated both efficacy and safety for red light therapy in promoting anti-aging skin rejuvenation and intradermal collagen increase when compared against controls. (7) Researchers concluded that red infrared therapy “provides a safe, non-ablative, non-thermal, atraumatic photobiomodulation treatment of skin tissue with high patient satisfaction rates.”
Subjects treated with red light therapy experienced significantly improved skin complexion, improved skin tone, improved texture/feeling, reduced skin roughness, reduced signs of wrinkles and fine lines, and increased collagen density as measured through ultrasonographic tests. Patients with rosacea and redness have also found relief using LLLT, even those who are unable to tolerate higher-heat laser therapies.
Yet another anti-aging effect of red light therapy is reversing hair loss and stimulating follicle growth, which works in many of the same ways as red light therapy for wound healing. Results have been mixed according to studies, but at least a moderate portion of both male and female patients have had positive results for reversing baldness/hair loss when using LLLT. (8)
4. Improved Joint and Musculoskeletal Health
Red light therapy is now being used to treat arthritis symptoms thanks to its capability of stimulating collagen production and rebuilding cartilage. A 2009 Cochrane review of red light therapy for rheumatoid arthritis concluded that “LLLT could be considered for short-term treatment for relief of pain and morning stiffness for RA patients, particularly since it has few side-effects.” (9)
Even in those who don’t suffer from arthritis but have other signs of tissue damage or degeneration due to aging, LLLT can still be beneficial. A 2009 study published in The Lancet showed, “LLLT reduces pain immediately after treatment in acute neck pain and up to 22 weeks after completion of treatment in patients with chronic neck pain.” (10) Other studies have found that even when patients with musculoskeletal disorders don’t experience less pain from red light therapy treatments, they have a high chance of experiencing “significantly improved functional outcomes,” such as better range of motion. (11)
Cellular rejuvenation and increased blood flow due to red light therapy are two key aspects of improving joint and tissue health. Decreasing oxidative damage, which degenerates joints, and modulating inflammation are other ways that LLLT benefits soft/connective tissue.
5. Reduced Depression and Fatigue
Another way to explain the benefits of red light is through the lens of Eastern medicine. Ask a Traditional Chinese Medicine practitioner how light helps improve health, immunity and recovery, and he or she will likely compare it to acupuncture’s mechanism of action:
Light is a form of energy, and our bodies are just big energy systems. Light has the power to stimulate specific meridian points and chakra zones in the human body.
Red is said to stimulate the first chakra because it correlates most strongly with our survival instinct (hence why it gives us energy and makes us act quickly, in order to motivate us to pursue things like money, food, sex, power, etc.).
While acupuncture uses tiny needles to achieve bodily harmony through stimulating certain points in the body’s energy system, light therapy uses focused, visible, red wavelengths in much the same way.
Red light has been shown to be naturally energizing and correlated with improved moods by increasing self-confidence, positivity, passion, joyfulness, laughter, social awareness, conversation skills and sensory stimulation. While results vary from patient to patient, there’s reason to believe that LLLT has mental and emotional perks in addition to physical benefits.
Red Light Therapy vs. Blue Light Therapy: What’s The Difference?
Blue and red light therapies, two forms of phototherapy, have some similar benefits and uses, although they work in different ways. The mechanism of action of both is still not entirely well-understood, but it’s believed that LLLT devices produce light with wavelengths similar to those of blue light lasers only with broader output peaks (they’re less monochromatic and don’t produce heat or friction).
Blue light is more commonly used at home from light-emitting devices, especially for the treatment of acne. It’s been found that blue light reaches the sebaceous (oil) glands in the skin and can help kill porphyrins, which are compounds inside acne bacteria. (12)
Red light is believed to penetrate the skin deeper and may also help acne and other skin disorders by reducing inflammation and improving healing.
Blue light and red light can be emitted from tabletop light therapy devices (which are used at home and usually weaker, requiring about a total of 30 minutes to one hour of treatment time twice per day) or from stronger devices used in doctors’ offices that work quicker (sometimes within just several minutes or less).
The Wellman Center for Photomedicine at Massachusetts General Hospital explains that there’s still widespread uncertainty and confusion surrounding the mechanisms of action of these light therapies, especially LLLT, at the molecular, cellular and tissue levels. There are also a large number of parameters for doctors to consider before treating individual patients (wavelength, fluence, irradiance, treatment timing and repetition, pulsing, and polarization) that can add to the confusion and patient variability in terms of results. (13)
Where to Go and How to Use Red Light Therapy
Many conventional doctors consider red light therapies to still be alternative treatments, considering more research is needed overall to prove their efficacy and results can sometimes vary. Currently most medical insurance companies state that LLLT is an “experimental treatment” so many won’t provide insurance coverage. Depending on what condition you’re treating, you can speak with your dermatologist, oncologist, orthopedic, rheumatologist or neurologist about treatment options. Your primary care doctor, or a chiropractor, may be able to give you a referral.
Red Light Therapy Research and Historical Use
Different types of phototherapy light boxes have actually been used for decades to treat numerous mood-related, skin, sleep-related, and acute or chronic pain conditions.
A 2012 report published in Annals in Biomedical Engineering stated that red light is used in three primary ways: “to reduce inflammation, edema, and chronic joint disorders; to promote healing of wounds, deeper tissues, and nerves; and to treat neurological disorders and pain.” (14) It’s been found that red light therapy promotes stronger immunity and longevity by increasing cell proliferation and migration, as well as modulating levels of cytokines, growth factors and inflammatory mediators.
Starting in the late 1990s, NASA scientists began developing infrared light technologies that could be used for plant growth during shuttle missions. What they discovered over the past two-plus decades is that red light therapies could also provide healing cellular stimulation in humans and animals.
Here’s an overview of how red light therapy is believed to be effective:
Red light — even just seeing the color red — stimulates all of our senses, primes us for quick movement and deliberate action, and enhances courage. Because it grabs our attention, you’ve probably noticed that the color red is used on many warning signs and traffic signals in order to cut through clutter and alert us of danger. So what does the effect of seeing red have to do with healing?
Leanne Venier — an engineer, scientist and an expert in light frequencies and the healing effects of color therapy — explains that red light is naturally attention-getting, energizing, stimulating and “representative of survival, joy and passion” in humans because of how it affects of our central nervous system. According to her work, along with extensive research done by trustworthy organizations including NASA, red light can trigger the sympathetic nervous system and therefore activate the “fight or flight response.”
Being in fight-or-flight mode causes reactions like improved blood circulation, rapid heartbeats, increased sweating, high concentration and so on. Normally we think of activating our stress response as a bad thing, but this can also be healing because it carries nutrients to our cells and controls inflammatory responses.
Possible Side Effects/Cautions Regarding Light Therapy
Although red light therapy seems to be very well-tolerated and unlikely to cause side effects, it still remains controversial whether it can help all patients. One difficulty that researchers have had gathering results from studies on red light therapy is pinpointing which light ranges are optimal for treating different health conditions and different patients.
Certain published study results have found that LLLT can cause negative reactions when an inappropriate choice of light source or an inappropriate dosage is used. There is an optimal dose of light for any particular application, and in the case of red light therapy, often lower doses are found to be more effective than higher doses. Be sure to work with a qualified LLLT practitioner whenever receiving treatments, and report any side effects, including burning, swelling, dizziness, muscle weakness or nausea. Keep in mind that seeing results from red light treatments might take patience and that responsiveness is expected to vary.
Final Thoughts on Red Light Therapy
Red light therapy (sometimes called LLLT or low level laser therapy) involves emitting red, low-light wavelengths through the skin to stimulate cellular rejuvenation, increase blood flow, stimulate collagen and more.
Red light therapy/LLLT is used to help treat conditions such as cancer treatment side effects, wounds, wrinkles or fine lines, hair loss, arthritis symptoms, musculoskeletal disorders, and neurological damage.
Red light therapy is well-tolerated by most, but results can vary. Researchers and experts feel there is still a lot to learn about how color/light laser therapies work, which means they remain controversial and not always covered by insurance.
RLT has shown promising results in treating some skin conditions, but within the scientific community, there’s not much consensus about the treatment’s benefits. Based on the current research, you may find that RLT is a good tool to add to your skin care regimen. Always check with your doctor or dermatologist before trying something new.
You can easily purchase red light devices online, but it’s best to get a doctor’s opinion on any symptoms before you try to self-treat. Keep in mind that RLT isn’t FDA-approved for most conditions or covered by insurance companies. Any serious condition, like psoriasis, arthritis, slow-healing wounds, or pain should be checked out by a doctor.
