Red light, at specific wavelengths, is readily absorbed by chromophores in the mitochondria of the body’s cells, which activates metabolic energy processes. Red and near-infrared wavelengths of light promote ATP production, which boosts energy transport within cells, leading to increased cell proliferation.
This boost in the body’s natural healing cycle helps reduce inflammation and promotes healing of damaged tissue.
What makes red light different from other forms of light is its ability to penetrate deeper into the skin. While blue and ultraviolet light mainly affects the upper layers of skin, red light can be absorbed by cells deep in the body. Red light therapy is also referred to as photobiomodulation therapy because of the change in the body induced by light, including reducing free radicals and oxidative stress.
Red and near-infrared light penetrate tissues, stimulating cytochrome enzymes in mitochondria. This enhances ATP production, reduces inflammation, and improves mitochondrial efficiency. It also promotes a healthy redox balance, increasing net negative charge and reducing protons, which translates to lower inflammation and higher physiological productivity.
