Red light therapy

Red light therapy, also known as photobiomodulation, is a form of low-level laser therapy that utilizes red and near-infrared light to stimulate cellular processes and improve energy production. This type of light is absorbed by cells, particularly those containing copper enzymes, which are essential for mitochondrial energy production 1.

Red light therapy has been shown to restore enzyme activity, improve cognitive function, and increase oxygen consumption in the brain, making it a potential treatment for various conditions, including Parkinson's disease 2. The therapy works by re-oxidizing copper enzymes, which are the final step in the mitochondrial energy-producing system, thereby increasing ATP production 1.

Research has also demonstrated that red light can counteract the toxic effects of ultraviolet light, which can cause cataracts and other eye problems 3. Additionally, red light has been found to have a protective effect on water, which may help explain its restorative actions 3.

However, there is some debate about the potential interactions between red light therapy and other treatments, such as methylene blue (MB). Some studies suggest that MB may cause cellular damage when combined with red light therapy, although this is still a topic of discussion 5.

In terms of practical applications, Ray Peat recommends using red light therapy to alleviate night-time stress and improve sleep quality. He also suggests that red light can repair damage caused by radiation, including ultraviolet light and X-rays, within the first hour of exposure 8.
