Just by going about our daily activities, we shed skin and release moisture in the form of sweat. Every minute, tens of thousands of dead skin cells are lost. The old cells fall away without any effort on our part, and are immediately replaced with new cells. Normal washing assists in the removal of dead cells from the skin. Cleansing and exfoliating are encouraged by beauty experts, so that our complexions look better; however, it should not be done too often or vigorously or you might leave skin that is unprotected from bacteria.
Sweating is a way the skin helps get rid of waste from the body. Sweating also cools us off when our body temperature rises too high; this process is called thermoregulation. We have two types of sweat glands. The eccrine gland is the gland responsible for cooling us down. Sweat from the eccrine glands is entirely almost water mixed with small amount of salt. Sweat itself is odorless. The sweaty smell comes from the apocrine glands located in covered hairy parts of the body. Sweat from these glands produces a protein that is metabolized by bacteria, emitting an unpleasant odor.
