|
triggers a neural response that responds to increased heat.

Explanation:
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: -This is because only approximately 20% of the energy produced in contracting muscles is used for muscle contraction; the remaining 80% is converted to heat energy, and therefore exercise causes an increase in muscle temperature. The heat is distributed to the body by the circulation and increases body temperatures.
