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. It’s a simple add-on for any sport and for everyday movement.

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 composed 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
Photobiomodulation with red and near-infrared light promotes blood circulation by increasing nitric oxide (NO) availability, improving endothelial function, and restoring vascular balance. This can be effective in treating cardiovascular diseases. (R)Red light at a wavelength of 660 nm enhances blood flow by releasing nitric oxide (NO), which causes vasodilation and lowers blood pressure. (R)
Red light at 670 nm has been shown to improve circulation by stimulating the release of nitric oxide precursors, leading to sustained blood flow increases. This could serve as an effective home therapy for people with reduced blood flow in extremities. (R)
Photobiomodulation with red light at 670 nm improves circulation by stimulating endothelial cells to release more nitric oxide (NO), resulting in vasodilation and better blood flow even under conditions of reduced NO availability, such as in diabetes. (R)
