far-infrared increases vascular shear stress and supports nitric oxide production pathways
FIR therapy improves blood flow in heated surface areas, causing an increase in vascular shear stress and enhancement of GTP cyclohydrolase I activity, which benefits tetrahydrobiopterin (BH4) synthesis — a critical cofactor for NO synthases.
What this means for you
Nitric oxide is your body's natural signal for blood vessels to relax and open up — better circulation, lower vascular tension, more oxygen reaching your tissues. This finding suggests far-infrared warmth activates a key enzyme step that helps your body make more of it, which most people notice as improved circulation and a sense of physical ease.
