“All living things require light just as they need air, food and water.”
New cells are constantly being made in our body. If our voltage is too low, this will hinder the body in making healthy new cells.
Light is more than meets the eye. The effects of light (and light therapy) on the human system is greater than ever expected. When I first set out to achieve peak mental performance, the thought that light could be a key tool in my arsenal wasn’t a reality. Until I came across ShedLight.
Light therapy, especially in the right wavelengths, could be one of the most well-researched and effective performance enhancers currently available.
Different wavelengths will affect human performance in different ways. By optimizing the type and duration of light we receive, it’s possible to vastly improve sleep quality, cognitive markers, reduce inflammation, slow aging, boost the immune system and provide more energy for the mitochondria.
Benefits of Photobiomodulation:
By increasing CCO and mitochondrial energy production, there are a number of downstream effects. Almost, if not all, benefits of photobiomodulation revolve around this major advantage.
Cognitive Enhancement – while less studied than some of the other photobiomodulation benefits, there is ample evidence to suggest substantial cognitive enhancement through light therapy. A 2017 study in Photomedicine and Laser Surgery showed that near infrared light therapy could increase reaction time with no adverse side effects .
We do know that cytochrome oxidase has a key role in neuronal physiology. This mechanism is the same as methylene blue, which increases memory formation, learning, and neuroprotection.
Reduced Inflammation – inflammation is one of the scourges of physical and mental performance. It contributes to pain, brain fog, and a host of other chronic diseases. The most insidious aspect of inflammation is that we can “survive”, but we’re definitely not thriving.
Although applying direct red and infrared light to an inflamed area (i.e: injury) can be extra helpful, simple application to the body changes inflammatory markers in the blood. One study showed reduced numbers of pro-inflammatory cytokines (like TNF-a) in the blood after only 30 minutes .
On average the inflammatory markers fell by 34, 12, and 1.5 times the normal amount. The red and near infrared therapy seems to really move the needle in terms of inflammation (these aren’t trivial amounts).
Anti-Aging – time takes a toll on us all, but red and near infrared light therapy can significantly reverse some signs of aging. This is most clearly seen with the skin.
One study showed using 20 minutes of 633 and 830 nm light (red and near infrared light therapy) could improve skin tone and reduce wrinkles in 91% of subjects . Another showed that red and near infrared light therapy stimulated collagen production to reduce aging skin . A final trial combined green tea with red light to find results that usually took 10 months were found in 30 days .
While most of the current evidence focuses on the skin (there are no epidemiological studies of people exposed purely to red and near infrared light), one can assume similar responses within other organs of the body.
Increased Testosterone – if females enjoy the skin rejuvenating benefits of red light therapy, men will assuredly like increasing their testosterone. The light (especially when shined on the testis) stimulates Leydig cells, which increase testosterone production.
A study published in Biomedical Research showed that it only took 4 days to increase testosterone levels in animal models (30 min per day 670 nm wavelength) . In that study plus another, using the wavelength of 808 nm had no impact, which shows that the wavelength does matter (red light specifically) . So please don’t go perving around the neighborhood pool with your pants down…
Testosterone can increase muscle size and strength, but also has consequences for the brain. Low testosterone can reduce cognitive performance, mood, and accelerate signs of aging. Improving levels of testosterone can enhance mental performance.
Without going into too much detail, here are some of the other benefits of near infrared and red light therapy:
Reduced joint pain / arthritis 
Better thyroid gland regulation 
Weight loss / fat reduction 
Muscle recovery and athletic performance
