why do we sweat?

Sweating is the body’s natural mechanism for controlling its temperature. Sweat evaporating from the skin cools the blood and this lowering of the blood’s temperature is used to help regulate the temperature of the other organs around the body. Every human body has approximately two million sweat glands, mostly located in the armpits, around the head, palms and feet; these glands produce approximately half a litre of sweat a day. At very high temperatures the sweat glands can produce up to six litres a day.
