far-infrared and steam exposure increase nitric oxide production in blood vessel walls
Enhanced endothelial nitric oxide production
What this means for you
Nitric oxide is your body's natural signal to relax and widen blood vessels. When production goes up, circulation improves — which most people feel as better warmth, less tension, and more efficient delivery of oxygen and nutrients to muscles, skin, and organs.
