  • How does sweat cool you down?

    Q: How does sweat cool you down?

    A: Sweat uses evaporative cooling to maintain body temperature. As liquids evaporate, they shed molecules into the air. The liquid changes into a gas, drawing heat from the liquid. The process draws heat from the body. Evaporation also cools the remaining liquid because faster-moving hot molecules are more likely to escape into the air, according to HowStuffworks.
