17 Mind-Blowing Facts About Sweat.

17 Mind-blowing facts about sweat.

1. You have 2 to 5 million sweat glands spread across your body. 2 main ones that are recognised are, eccrine and apocrine.

Eccrine glands cover the majority of your body and produce most of your sweat; mainly concentrated on your palms, soles, forehead and armpits.

Apocrine glands are larger and are in your armpits, groin and breast areas. They produce your ‘stress sweat’ and are associated with BO; they’re near your hair follicles and combine with bacteria which causes the smell.

2. There are differences between ‘stress sweat’ and ‘regular sweat’. Regular sweat is made of water, salt and potassium and it helps to cool your body down as it evaporates.

Stress sweat is comprised of fatty acids and proteins and it doesn’t evaporate as quickly. It doesn’t control your temperature but it helps you to get ready for your fight-or-flight response.
