far-infrared and steam cause blood vessels to widen and vascular resistance to drop
Vasodilation and decreased systemic vascular resistance
What this means for you
When blood vessels relax and open up, your heart doesn't have to work as hard to push blood through your body. Most people notice this as a sense of physical ease, warmth spreading through the limbs, and a calmer, more relaxed feeling — the kind of deep unwind that's hard to get from rest alone.
The published research
Thermal vasodilation using a portable infrared thermal blanket in decompensated heart failure.
International heart journal · 2014
This RCT directly documents both vasodilation and decreased systemic vascular resistance from infrared thermal exposure. The thermotherapy group showed a 16.0% reduction in systemic vascular resistance (P=0.024) and a 24.1% increase in cardiac index (P=0.009), with the discussion explicitly attributing this to peripheral vasodilation via nitric oxide-mediated mechanisms.
