Why Do We Sweat?

Sweating is an essential and natural biological process that starts soon after we are born. Sweating, or perspiring, is the body’s mechanism of keeping us cool and preventing us from overheating in a warm environment or during exercise or exertion. Our body also produces sweat when we experience strong emotions or stressful situations, during hormonal changes and it helps to play a role in fighting infections.

Normally our bodies produce almost 1 litre of sweat per day, however most of this evaporates as soon as it is produced so we don’t notice it. The body produces more sweat during exercise or in warmer environments in order to help cool us down. If a person exercised very hard in the heat they could produce up to 10 litres of sweat in a day.
