Sweating is a natural function of the human body, allowing a body to cool itself as sweat emerges from glands and evaporates. Separately, this process may produce odors as bacteria present on the skin break down sweat proteins. A deodorant kills the bacteria that produce the odor, while an antiperspirant clogs sweat ducts to prevent sweat from emerging in the first place.
