dry-heat exposure raises core body temperature by ~0.7°C, normalizing within 6 hours
Dry-sauna exposure at 100°C caused a significant increase in core body temperature (from 37.0°C before to 37.7°C immediately after, P<0.01) that gradually normalized over 6 hours.
What this means for you
A temporary, controlled rise in core temperature is how your body mimics the effects of a mild fever — activating heat-shock proteins, circulation, and metabolic processes linked to recovery and resilience. Most people notice this as a deep, lasting warmth and a sense of physical ease that lingers well after a session ends.
