The purpose of perspiration was a mystery in 1775, when English physician Charles Brian Blagden and some curious friends subjected themselves to experiments by spending time in rooms heated to more than 230°F (110°C). Although the temperatures were high enough to cook raw meat placed in those rooms, Blagden observed how human bodies withstood the heat. Core body temperatures remained practically constant whilst sweat poured out and evaporated.
The science of sweat continues to reveal surprises, including how still, dry air hampers cooling
Historical and recent research shows that sweating is crucial for regulating body temperature, though certain environmental factors can interfere with this natural process.
