Red light therapy (RLT), also known as low-level laser therapy (LLLT) or photobiomodulation, is a treatment that uses specific wavelengths of red and near-infrared light to penetrate the skin and stimulate cellular function. This non-invasive therapy has been explored for a variety of health benefits, including wound healing, pain reduction, and skin rejuvenation. Recently, interest has grown in understanding whether RLT can influence metabolic processes, including blood sugar levels.
Red light therapy works by emitting wavelengths of light that are absorbed by the mitochondria, the energy-producing components of cells. This absorption increases the production of adenosine triphosphate (ATP), which enhances cellular energy and function. The improved cellular activity can help repair tissue, reduce inflammation, and promote healing.
