A German-language YouTube video (creator: Darrian Peck) introduces red light therapy (photobiomodulation) as a simple method to improve health, focus, and recovery. The speaker explains a proposed physiological mechanism: red/near-infrared light (around 670 nm) penetrates skin, stimulates endothelial cells to release nitric oxide, which relaxes vascular smooth muscle, causing vasodilation that improves blood flow and tissue oxygen/nutrient delivery.
