Sweating regulates body temperature and helps the body regulate its core temperature. The process of sweating cools down the body while taking in external heat, providing a cooling effect for any part of the human anatomy that is exposed to it. Sweating evaporates an organism’s water supply by removing moisture from its cells, aiding in cellular dehydration. As sweat dries on one’s skin, it produces salt through chemical reactions with dead tissue cells or other bodily fluids. This phenomenon occurs when organisms are dehydrated whereas they are losing fluid through evaporation into air spaces within their bodies or being lost due to perspiration that is released into the environment as vapor form sweat glands located on most parts of their bodies.
The rate at which this happens varies depending upon how much water you’re sweating out each day; people who do sports can lose more than twice as much salt via sweating during exercise than those whose activity does not require them to work up a sweat. Hyperhidrosis treatment generally involves prescription medications used to control excessive sweating under medical supervision. These include anticholinergics (such as benztropine) or alpha-2 receptor antagonists (anti-muscarinic agents such as tiotropium).
