The Healing Power of Red and Near-Infrared Light


Research since the year 2000 shows how different types of light can affect our body's chemistry and health. Of particular interest are red (RED) and near-infrared (NIR) light, which have demonstrated remarkable therapeutic potential.


Our eyes can see red light and our skin absorbs it. Near-infrared light is invisible to us but penetrates deeper into the body. This light benefits mitochondria, cells, organs, and glands.

In the last 20 years, there have been many studies on using red and near-infrared light for therapy. These studies show that this type of light can help our bodies in different ways. We can categorize these effects into nine key areas, each offering unique benefits for our overall well-being.

  • Recovery & Athletic Performance

  • Hormonal System

  • Skin, Hair & Nails

  • Sleep & Circadian Rhythm

  • Musculoskeletal System

  • Mental & Cognitive Function

  • Reduction of Inflammation

  • Eyesight

  • Longevity & Vitality



you can use red light therapy for recovery from hard workouts.

Recovery & Athletic Performance


With the science behind red light therapy, one of the most popular applications of red light therapy is its use in enhancing athletic performance and promoting post-exercise recovery. Red light therapy boosts energy in cells and collagen production, leading to stronger muscles, faster recovery, and less fatigue. Several scientific studies have demonstrated its effectiveness in improving muscle performance, reducing muscle damage biomarkers, and enhancing muscle strength gains in athletes and individuals with muscle injuries.


For instance, a meta-analysis examining the effects of red light therapy on exercise performance found positive results, including improved time to exhaustion, number of repetitions, isometric peak torque, and reduced blood lactate levels. Moreover, near-infrared light therapy has been shown to enhance muscle hypertrophic response and strength gains when applied before eccentric training. These findings highlight the potential of red light therapy in optimizing athletic performance and accelerating muscle recovery.


Red light therapy helps with balancing your hormones

Hormonal System


The hormonal system plays a crucial role in maintaining overall health and well-being. Red and near-infrared light therapy has been found to have a positive impact on various endocrine glands, including the thyroid gland and testosterone production in both men and women. Studies have shown that red light therapy can increase testosterone levels, improve thyroid function, and enhance spermatogenesis in men. Similarly, women can benefit from targeted red light therapy in the crotch area, which can increase testosterone production and promote overall hormonal balance.


Have healthier skin hair and nails with red light therapy.

Skin, Hair & Nails


As we age, the natural synthesis of collagen in our body gradually declines, leading to the formation of wrinkles and a decrease in the quality of hair and nails. Red and near-infrared light therapy offer a solution to combat these signs of aging by stimulating collagen production and promoting skin rejuvenation. Scientific studies have shown that red light therapy is effective in the treatment of acne vulgaris and improves hair counts in individuals with androgenetic alopecia.


Moreover, red and near-infrared light therapy have been found to reduce wrinkles, fine lines, and increase skin collagen density. These therapies also have anti-inflammatory properties, making them effective in accelerating wound healing and increasing collagen synthesis. The use of red light therapy has also demonstrated positive effects on skin moisture and wrinkle reduction in women.


Get better sleep with red light therapy.

Sleep & Circadian Rhythm


The circadian rhythm regulates our body's natural processes on a 24-hour cycle. To improve our body clock, avoid blue light before bed and get bright light in the morning. Red light therapy helps regulate our sleep cycle by imitating the sunrise's light spectrum, making it an ideal solution. Studies have shown that red light therapy can improve sleep quality, increase melatonin secretion, and reduce sleep disturbances.


Strengthen your bones with red light therapy.

Musculoskeletal System


Red and near-infrared light therapy offer significant benefits for our musculoskeletal system, including the prevention and regeneration of joints, tendons, and bones. These therapies reduce inflammation and promote collagen synthesis, two crucial factors for maintaining a strong musculoskeletal system. Scientific studies have demonstrated the effectiveness of near-infrared light therapy in treating knee osteoarthritis and improving microcirculation.


Also, red and infrared light can speed up bone healing and boost the growth of bone cells, collagen, and new bone. This study shows that red and near-infrared light therapy can keep muscles and bones healthy and prevent damage.
