MEDICAL PHYSIOLOGY

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: -As perspiration evaporates it absorbs heat to cool your body. The principle underlying evaporative cooling is the fact that water must have heat applied to it to change from a liquid to a vapor. When evaporation occurs, this heat is taken from the water that remains in the liquid state, resulting in a cooler liquid.

Detailed explanation-3: -The sweat leaves your skin through tiny holes called pores. 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.

Detailed explanation-4: -Evaporation of the sweat from the skin causes a cooling effect. This is because water droplets present on the skin require some heat to evaporate, which they take from the body.

Detailed explanation-5: -Your body sweats when it gets hot. The water on your skin evaporates into the air around it. It is the process of evaporation that creates cooler temperatures for your skin because of the endothermic process pulling the heat from the surrounding air to complete the evaporation process.
