Sweating has more underlying functions beyond body cooling. There are three additional distinctive roles of sweat beyond Cooling the body.
The four primary roles are:
- It regulates the body's temperature.
- Release of excess salts and toxins. (This is also the reason why sweat smells terrible.)
- The body's smell transmits signals. (Mainly to the opposite sex.)
- In response to stress or fear, sweating helps keep people alert.
There is often sweating in high fever situations, which serves two primary purposes: natural cooling of the body and removing salts and toxins. Drinking a lot is designed to allow sweating without losing significant amounts of fluid in the body.
