passive heat exposure raises heart rate by up to 64%, mirroring a metabolic boost
Passive heat exposure at 50°C–50% RH produced a 64% increase in heart rate compared to baseline, with heart rate strongly correlating with metabolic rate (conditional R²=0.45).
What this means for you
When your heart rate rises in response to heat, your body is working harder — burning more energy and circulating blood more actively, much like light exercise. This kind of passive cardiovascular engagement may support circulation and metabolic activity even on days when physical exertion isn't possible.
