thermal vasodilation from sauna heat improves blood flow and reduces cardiovascular strain
Thermal therapy with a 60°C sauna produced acute hemodynamic improvement through thermal vasodilation in congestive heart failure patients.
What this means for you
When heat causes blood vessels to widen, the heart doesn't have to work as hard to push blood through the body. For most people, this translates to a noticeable sense of ease and warmth — and over time, better circulation supports energy, recovery, and cardiovascular resilience.
