Red light exists at the highest end of the visible spectrum (from 600-700nm) and near infrared (700-100nm) is just beyond what the visible eye can detect. Red and near infrared light each have distinct properties and can be used independently, or combined for maximum healing and versatility. Because of NIR light’s deeper absorption into the body, it can penetrate bones, joints, large muscles, and tissues. NIR Light therapy encourages cellular repair and regeneration by increasing cellular metabolism, which can slow or even halt the inflammatory response and give the body a chance to repair itself. How it works – Near-infrared light therapy Laser therapy works by stimulating a process called photobiomodulation (PBM) in which photons enter the tissue and interact with the Cytochrome C complex within mitochondria. Invisible near-infrared energy is absorbed by photoreceptors in each cell. Once absorbed, the light energy kicks off a whole series of metabolic events, stimulating the body’s natural processes on a cellular level.
