What is Near-Red Light Therapy?

Near-infrared light therapy involves exposing the body to light in the near-infrared spectrum, which ranges from 650 to 1000 nanometers (nm) in wavelength. This section of the light spectrum sits between visible red light (620-750nm) and infrared light (750nm-1mm). Near-infrared light is part of the electromagnetic spectrum. It has longer wavelengths and lower frequencies than visible light. This allows it to penetrate deeper into the body’s tissues without causing damage.

When near-infrared light is delivered to the body through light-emitting diodes (LEDs), it is absorbed by mitochondria within the cells. Mitochondria act as “energy factories” that produce adenosine triphosphate (ATP), the primary source of cellular energy.

Near-infrared light boosts ATP production and other cell functions through a process called photobiomodulation. The light stimulates cytochrome c oxidase, a protein in the mitochondria’s respiratory chain. This kickstarts a cascade of reactions that ultimately triggers beneficial changes like:

  • Increased cellular energy and vitality
  • Improved blood flow and circulation
  • Reduced inflammation and pain
  • Faster healing and tissue regeneration

In short, near-infrared light delivers energy to rev up your body’s innate healing, self-repair, and self-regulation mechanisms. Let’s look now at the top 5 ways this can improve your health.

Benefits of Near-Infrared Light Therapy

Near-infrared light therapy has shown therapeutic value and clinically-proven benefits for a wide variety of health conditions, aesthetic concerns, and sports performance enhancement. Some main areas supported by research include:

1. Improved Skin Health and Appearance

Near-red light is safe for all skin types and improves a number of cosmetic skin concerns. It can rejuvenate the face, reducing wrinkles, fine lines, and hyperpigmentation.

The light boosts ATP production in skin cells, increasing collagen and elastin synthesis. This makes the skin appear plumper and more youthful. Near-red light also repairs UV damage from the sun and environmental pollution.

Regular use of red light therapy evens out skin tone, fades age spots, and refines the pores. It is helpful for healing acne lesions and reducing inflammation from breakouts.

2. Relieve Pain

One of the most researched uses of photobiomodulation is for reducing pain and inflammation. The light has been shown in clinical trials to effectively treat chronic neck and back pain, osteoarthritis, rheumatoid arthritis, fibromyalgia, post-surgical pain, and neuropathic pain from diabetes, chemotherapy, and other conditions.

Red and near-infrared wavelengths penetrate tissue deeply to reduce inflammation at the cellular level. This eases painful symptoms. The light also seems to reduce pain signals transmitted through the nerves.

3. Improved Healing from Wounds and Injuries

Photobiomodulation accelerates the healing process for both chronic and acute wounds by reducing inflammation, stimulating new blood vessel growth, and activating fibroblasts for remodeling tissue.

Near-infrared light shortens healing time for burns, diabetic ulcers, abrasions, surgical wounds, and skin damage from cancer treatments like chemotherapy and radiation. It can be used to treat sports injuries, fractures, tendonitis, strains, and sprains.

4. Combatting Hair Loss

For those struggling with hair thinning and loss, near-red light therapy shows potential to stimulate hair regrowth. Here’s what the science says so far:

  • Activates hair follicles – Near-red light exposure increased follicle proliferation and growth phase in mice.
  • Protects follicles from damage – Near-red light protected mice hair follicles from cell death caused by chemotherapy drug.
  • Improves growth cycle – Human trials found near-red light therapy extended anagen (growth) phase of hair follicles.
  • Decreases inflammation – Near-red light reduced inflammation around follicles that can cause hair loss.

5. Muscle Recovery and Performance

Athletes and those leading active lifestyles can benefit from near-red light therapy to boost muscle performance, increase endurance, and speed up recovery.

Photobiomodulation helps relieve muscle soreness after exercise. It also reduces oxidative stress and inflammation from intense training. This aids muscle recovery so athletes can train harder.

The Scientific Evidence Behind Near-Red Light Therapy

The wide range of benefits from near-infrared light therapy are strongly supported by over 5,000 published studies and clinical trials. Research into photobiomodulation by near-red light has increased exponentially since the 2000s. Here is a sampling of the compelling scientific evidence:

  • A 2009 study found that after study participants received 12 sessions of red light treatment, more than 90 percent experienced a reduction in wrinkle depth and surface roughness.[1]
  • A 2010 study found that patients with chronic psoriasis experienced a significant reduction in skin inflammation after using 830-nanometer and 633-nanometer red light therapy.[2]
  • In a 2006 randomized controlled trial, patients who had suffered from chronic low back pain for at least six years experienced a 50% reduction in pain after receiving infrared light therapy, while the control group reported only a 15% reduction in pain.[3]
  • Another controlled study that same year found that red light therapy can be an effective short- and long-term treatment solution for reducing fibromyalgia pain in patients.[4]
  • Multiple studies have shown that near-red light can accelerate the healing of burn scars with few risks or side effects.[5 6]
  • A 2007 study found that male AGA patients who used near-red light therapy for 14 weeks had increased hair density.[7]
  • A 2014 study found that women with androgenetic alopecia experienced a 37% increase in hair growth after red light treatment compared with a placebo group.[8]
  • A 2006 randomized, double-blind controlled study found that subjects who received red light therapy showed a significant reduction in DOMS-related pain compared to a control group.[9]
  • A 2014 randomized, double-blind crossover trial also found an increase in muscle fatigue resistance when using red light therapy before, during, and after strenuous exercise.[10]

Pros and Cons of Near-Red Light Therapy

If you are considering trying near-infrared light therapy, it is helpful to understand both the potential benefits and the limitations of this treatment approach:

Pros of Near-Infrared Light Therapy:

  • Non-invasive and drug-free. No injections, medications or surgery needed.
  • Safe for most people. The FDA has approved it as a safe, non-significant risk treatment. Side effects are rare.
  • Convenient and easy. Painless, quick, can be done at home. No recovery time needed.
  • Effective for many conditions. Clinically proven to help treat pain, healing, cognitive and skin conditions.
  • No dependence or tolerance build-up. Effects are cumulative without any addiction or tolerance.
  • Synergistic with other treatments. Can be combined with medications, exercise, diet, supplements.
  • Relatively affordable. Devices have dropped in price recently. Lower cost than many drugs or procedures.

Cons of Near-Infrared Light Therapy:

  • Results take time. Benefits are gradual and optimal results typically require 2-4 weeks or more of consistent sessions.
  • Specific wavelengths and dosages are vital. Improper or ineffective devices may lead to no results.
  • Does not work for all individuals. As with any treatment, some people may not respond significantly.
  • Daily use needed. Consistency is key but time-consuming. Forgetfulness can limit results.
  • Eye protection important. Exposure can damage eyes so protective eyewear should be worn.


Overall the many benefits and minimal risks mean near-infrared therapy is worth considering for those seeking an alternative, non-invasive treatment for chronic issues like inflammation, pain, poor circulation, or slow healing.
