At its core, infrared light therapy employs light-emitting diodes (LEDs) to emit wavelengths typically ranging from 700 to 1,000 nanometers. Unlike the harsh ultraviolet rays that scorch the skin, infrared light penetrates deeper into tissues, reaching muscles, nerves, and even lymphatic structures. The mechanism hinges on stimulating mitochondria—the powerhouses of cells—to produce more adenosine triphosphate (ATP), the molecule that fuels cellular activity…
