When your sweat glands are triggered, they secrete sweat on your skin’s surface. Sweat is made up mostly of water and salt. When it is released it lowers your body’s temperature.
When your body reacts to you being in a warm, stressed or physically demanding environment it turns on its natural cooling system – sweating.
Your body has 2.6 million sweat glands, on average. They are found on almost every part of your body – your lips being one of the few places where you don’t sweat.
Your sweat glands are made up of two main parts, the coiled section – where sweat is produced and the duct – the path your sweat takes to reach the surface of your skin. However, not all sweat glands were created equal. You have two types of sweat glands:
1. Eccrine Sweat Glands:
Eccrine glands are found all over your body, but the highest concentrations are in your palms and the soles of your feet. Sweat from your eccrine glands is made up of mostly water, salt and potassium.
2. Apocrine Sweat Glands:
Your apocrine glands are found where you have the most amount of hair follicles – your underarms, groin and scalp. In emotional or stressful situations, you sweat from your apocrine glands. This type of sweat is thicker and contains fatty acids and proteins.
