@lkirnbauer Red light therapy at ~650nm (red) and ~850nm (near-infrared) aids back surgery recovery by boosting cellular energy, reducing inflammation and pain, increasing blood flow for nutrient delivery, promoting collagen for tissue repair, and stimulating nerve regeneration, helping to heal damaged tissues, minimize scarring, and restore function after surgery. These specific wavelengths penetrate deep to activate mitochondria, fueling the body's natural repair processes for faster, better healing.
