Red light therapy works by stimulating the mitochondria, which are responsible for producing energy within cells. When cells absorb red or near-infrared light, it enhances mitochondrial function, leading to an increase in adenosine triphosphate (ATP) production. This increase in ATP provides cells with more energy to perform their functions efficiently. Additionally, red light therapy has been shown to activate certain enzymes and signaling pathways involved in cellular repair and regeneration processes. Overall, these cellular effects contribute to the various therapeutic benefits observed with red light therapy, including improved wound healing, reduced inflammation, and enhanced tissue recovery.
