heat exposure elevates cardiac output for up to 3 hours after a session
The increase in cardiac output following sauna exposure remained elevated up to 3 hours post-exposure, until gradual normalization of heart rate and venous return associated with progressive cooling of the skin.
What this means for you
Cardiac output is simply how much blood your heart pumps per minute. When it stays elevated for hours after a heat session, your body keeps circulating more oxygen and nutrients to muscles, skin, and organs — similar to the lingering effect of light aerobic exercise. For most people, this translates to a sustained sense of warmth, easier recovery, and cardiovascular conditioning over time.
