Red and near-infrared light therapy works by increasing mitochondrial energy production in cells. Mitochondria are the powerhouses of cells, producing energy in the form of ATP (adenosine triphosphate). The specific photons in red and near-infrared light interact with a cellular photoreceptor called cytochrome c oxidase. This interaction enhances mitochondrial efficiency, increasing ATP production and improving cellular function. Enhanced cellular energy leads to better performance and health throughout the body.
