When we get sweaty, it’s from either two types of sweat glands on the skin: Apocrine – found mainly in the underarm area – and Eccrine glands, which are found all over the skin surface. Sweating is controlled by the body’s autonomic nervous system – the part of our nervous system which is under involuntary or ‘unconscious’ control.
Apocrine glands become active from puberty and are found mainly in the underarms. They produce sweat when we feel stress, pain or exercise. The sweat from apocrine glands that’s responsible for producing smelly sweat. Eccrine glands are the most abundant type of sweat gland, found all over the skin and start to function soon after birth, releasing a dilute salt solution made up of 99% water. It’s the Eccrine gland that’s responsible for the wet sensation of sweat. Sweat produced from the Eccrine glands are key in keeping the body cool by thermoregulation.
