In a recent newsletter, Dr. Mark Hyman referenced a clinical study on near-infrared light that we thought you might like to know a little more about. The study, Photobiomodulation directly benefits primary neurons functionally inactivated by toxins: Role of cytochrome c oxidase¹, was published about five years ago in the Journal of Biological Chemistry (an academic medical journal published by the American Society for Biochemistry and Molecular Biology).
Low-intensity light therapy, commonly referred to as “photobiomodulation,” uses light in the far-red (note that this is NOT far-infrared) to near-infrared region of the spectrum and changes some cellular functions.
The researchers believed that far-red and near-infrared (NIR) light promotes wound healing, but wanted to understand exactly how that occurred. NIR light has been used in therapeutic devices for the treatment of a variety of injuries. It penetrates more deeply than UV or visible light and is benign to living tissue.
Previous studies NIR LED arrays suggested that cytochrome c oxidase, a photoacceptor (a part of the cell that can induce metabolic change) in the NIR range, plays an important role in therapeutic photobiomodulation. The study results were consistent with what the researchers believed would happen – that photobiomodulation involves the up-regulation of cytochrome c oxidase. And that this leads to increased energy metabolism in neurons functionally inactivated by toxins, arresting cell death.
Ultimately, the researchers concluded that the therapeutic effects of photobiomodulation in promoting wound healing and in overcoming intoxication by various toxins that inactivate cytochrome c oxidase were documented in clinical studies. They opined that future applications of this treatment approach, especially with the low risk LED arrays, can and should be considered for various biological ailments and diseases such as those that involve cellular metabolism and energy production.
Sunlighten’s newest infrared sauna model, the mPulse, features Solocarbon Custom Spectrum® Heating Technology. This provides its user with access to the full spectrum of infrared therapy – including the NIR waves discussed in the photobiomodulation studies.
The mPulse’s advanced LEDs provide near infrared at a singular wavelength with minimal variability for consistency of output, which is exactly what independent research supports. Others may claim near infrared, but without this proprietary LED technology developed by Sunlighten, it simply is not possible.
