Sweating is a natural process for the body to cool down the temperature to prevent overheating of the body. This can happen due to the temperature in the environment getting too hot for the body to take without reacting to it to cool off, or it can happen due to intense exercise where the body itself is working so hard that it becomes overheated and must cool down to prevent damage to the tissues. There are other instances that sweating happend due to illness, when the individual get a fever and the body tries to cool off with sweat. There are some people, however, who have excessive sweating, where they will sweat in their armpits, hands or feet in great amounts, which can cause a lot of embarrassment in public situations.
