Science & Effects of Red & Near-Infrared Light
We’ve read hundreds of studies, so you don’t have to. Clinical tests, theories, and evidence explaining why and how red and near-infrared light works. Today, there are already thousands of studies. Yet, at the turn of the millennium, you’d find only a handful of records.
The breakthrough came thanks to NASA’s research, which sparked scientific interest in this therapy. And with the growing number of studies, its applications are expanding.

How Can Red and Near-Infrared Light Help You?
Before diving into the individual benefits, take a moment here.
It’s the same with wavelengths. Where one ends, another doesn’t begin: they overlap and complement each other.
Recovery and Performance
In sports and active life, red and near-infrared light are used as part of warm-up and wind-down routines. Before effort, short sessions help you feel primed and energized. Afterward, they pair with your recovery ritual so you settle in and feel ready to go again soon. It’s a simple add-on for any sport and for everyday movement.

Scientific Studies
"Within the cell, there is strong evidence to suggest that LLLT acts on the mitochondria to increase adenosine triphosphate (ATP) production, modulation of reactive oxygen species (ROS), and the induction of transcription factors." (R)"The ability of LLLT to stimulate stem cells and progenitor cells means that muscle satellite cells may respond well to LLLT and help muscle repair. Furthermore the ability of LLLT to reduce inflammation and lessen oxidative stress is also beneficial in cases of muscle fatigue and injury."
"Athletes, people with injured muscles, and patients with Duchenne muscular dystrophy may all benefit." (R)
"Based on our findings, the use of PBMT in muscle recovery after high-intensity exercise appears to be beneficial, provides a clinically important effect, and seems to be the best option when compared to CRT (cryotherapy)." (R)
Natural Body Balance
Your body runs on quiet signals that guide energy, mood, and daily rhythm. Red and near-infrared lights work as a complementary support to balance these internal signals. Red helps you at the surface, near-infrared supports you deeper. When used together, they create an environment that promotes a natural inner balance and everyday vitality.

Scientific Studies
"Our results showed that the LLLT using a 670-nm diode laser was effective in increasing serum T (Testosterone) level without causing any visible histopathological side effects to the tissue. Thus the low level laser therapy may be an alternative treatment modality for conventional types of testosterone replacement therapy." (R)"The preliminary results indicate that LLLT promotes the improvement of thyroid function, as patients experienced a decreased need for LT4 (medication), a reduction in TPOAb levels (autoimmune disease markers), and an increase in parenchymal echogenicity." (R)
Beautiful Skin and Hair
Skin can lose some elasticity and glow as the years add up, fine lines show more easily, and hair and nails may feel less resilient. A comfortable red light ritual supports a smooth, fresh, even-looking skin look. Hair and nails can also benefit, feel shinier, and be better cared for.

"This study shows that red light phototherapy alone can be a new therapeutic option for acne vulgaris." (R)"LLLT of the scalp at 655 nm significantly improved hair counts in males with androgenetic alopecia." (R)
Better Sleep
Our body naturally follows a 24-hour biorhythm (circadian rhythm). You can help it not only by minimizing blue light exposure before sleep but also by adding some red and near-infrared light during the day or evening. This helps with daytime energy and restful sleep.

"Our study confirmed the effectiveness of body irradiation with red light in improving the quality of sleep of elite female basketball players and offered a nonpharmacologic and noninvasive therapy to prevent sleep disorders after training." (R)"We suggest that low-level laser stimulation is probably useful for patients with sleep problems." (R)
Unrestricted Movement
Like every other part of the body, the musculoskeletal system is a complex chain, everything works together. With near-infrared light, you can support your movement holistically. The goal is simple: feel comfortable, stay limber, and keep moving day after day without any limitations.

Scientific Studies
"Our results show that LLLT reduces pain in KOA (knee osteoarthritis) and improves microcirculation in the irradiated area.""In the active LLLT group, we found significant improvement with regard to joint flexion, pain, and pressure sensitivity in the active group in comparison with the placebo group at the times examined." (R)
Focus and Mood
Vitality isn’t only about the body. It’s also about how clear, steady, and uplifted you feel. Red and near-infrared light can support your focus and mood: they help you feel centered under pressure, think more clearly, and keep a brighter, more even outlook through stress-heavy days. Modern indoor life often lacks these positive wavelengths from sunlight, so adding them deliberately can make your day feel more balanced.

Scientific Studies
"Previous studies have used NIR to treat tissue stressed by hypoxia, toxic insult, genetic mutation and mitochondrial dysfunction with much success. Here we propose NIR therapy as a neuroprotective or disease-modifying treatment for Alzheimer's and Parkinson's patients." (R)
Eye Readiness
Blue light is everywhere these days. Screens, the primary source, surround us constantly. Red light acts as a counterbalance. It helps offset screen-heavy exposure negatives and brings a comfortable, refreshed feel to the eye area with gentle, non-UV wavelengths.

Scientific Studies
"Here, we use 670-nm light to improve photoreceptor performance and measure this psychophysically in those aged 28–72 years. Rod and cone performance declined significantly after approximately 40 years of age. 670-nm light had no impact in younger individuals, but in those around 40 years and older, significant improvements were obtained in color contrast sensitivity for the blue visual axis (tritan) known to display mitochondrial vulnerability. The red visual axis (protan) improved but not significantly. Rod thresholds also improved significantly in those >40 years. Using specific wavelengths to enhance mitochondrial performance will be significant in moderating the aging process in this metabolically demanding tissue." (R)
Lasting Vitality
This is where everything comes together. Red and near-infrared light sessions support how you feel today and the days after that. With regular use, it can support consistent day-to-day energy, a body that keeps up, and a clear, centered headspace. It’s a comfortable ritual your future self will appreciate. You will enjoy how you feel and how you look.

Scientific Studies
"In conclusion, photobiomodulation has been shown to alter the course of ageing in the central nervous system, by improving the survival and function of neurons and reducing gliosis and inflammation." (R)"Mitochondrial photostimulation has been shown to increase ATP production and cause transient increases in reactive oxygen species (ROS). In some cells, this process appears to participate in reduction/oxidation (redox) signaling. Redox mechanisms are known to be involved in cellular homeostasis and proliferative control." (R)
Everyday Resilience
Some days are tough on the body: lots of stress, crowded spaces, dry office air, sudden weather changes. A regular ritual with red and near-infrared light will help you feel strong, resilient, and ready to keep up the pace instead of running on empty batteries. It will help you stay vital and balanced, even in more challenging times.

Scientific Studies
"These results seem to indicate that a single low power laser irradiation can modulate immune-responses depending on the immunological status of the organism." (R)"The TEM findings in the present study showed a clearly-visible inflammatory response similar to the first phase of wound healing, a ‘quasi-wound’, but created athermally and atraumatically following a single treatment with 830 nm light, thereby kick-starting the inflammatory stage of the wound healing process which is recognized as absolutely necessary in achieving good subsequent collagen synthesis in the second phase of proliferation, followed by good remodeling in the third phase. Good results in skin rejuvenation, both ablative and non-ablative, have been well-linked to establishing the wound healing process." (R)
Body Flow and Pleasant Warmth
When your internal body flow is smooth, you simply feel good, light, and balanced. Red and near-infrared light supports your natural body flow process, promoting daily vitality and a feeling of lightness. Near-infrared light helps to enhance all these feelings thanks to its pleasant, gentle warmth.

Scientific Studies
"Recent studies consistently report that PBM improves endothelial dysfunction via increasing bioavailable NO in a dose-dependent manner and open a feasible path to the use of PBM for treating cardiovascular diseases via augmenting NO bioavailability." (R)"The results of this study demonstrate that the hypotensive and vasodilatory effect of PBM with a red laser at 660 nm is modulated by the release of nitric oxide from the storage." (R)
"Our results strongly support 670 nm light can regulate dilation of conduit vessel by releasing a vasoactive nitric oxide precursor species and may offer a simple home-based therapy in the future to individuals with impaired blood flow in the leg." (R)
"In conclusion, R/NIR stimulates vasodilation by release of NO bound substances from the endothelium. In a diabetes model of endothelial dysfunction, R/NIR restores vasodilation, which lends the potential for new treatments for diabetic vascular disease." (R)
