Detailed explanation-1: -That’s because cooling your body via sweating relies on a principle of physics called “heat of vaporization.” It takes energy to evaporate sweat off of your skin, and that energy is heat. As your excess body heat is used to convert beads of sweat into vapor, you start to cool down.

Detailed explanation-2: -The answer is evaporative cooling. Turning a liquid such as sweat from its liquid state into a gas requires energy. This energy is taken from our body, or sweat, in the form of heat. The resulting heat transfer leads to the desired cooling effect.

Detailed explanation-3: -Sweating is the release of liquid from the body’s sweat glands. This liquid contains salt. This process is also called perspiration. Sweating helps your body stay cool.

Detailed explanation-4: -When the sweat hits the air, the air makes it evaporate (this means it turns from a liquid to a vapor). As the sweat evaporates off your skin, you cool down. Sweat is a great cooling system, but if you’re sweating a lot on a hot day or after playing hard you could be losing too much water through your skin.
