Why do we Sweat?

The process of sweating is due to small structures in our skin known as sweat glands. Eccrine glands are responsible for producing a fluid which is 99 per cent water and which most people associate with underarm wetness. A second type of sweat gland, known as the apocrine gland produces a secretion that is broken down on the surface of the skin by bacteria. It is this breaking down process which actually causes the smells we associate with body sweat.
