\nPerspiration cools the body through the process of evaporation. When sweat (water) evaporates from the skin surface, it changes from a liquid to a gas. This phase change requires energy, which is absorbed from the skin and underlying tissues. This energy absorbed is known as the latent heat of vaporization. By absorbing heat from the body, the evaporation process effectively cools the skin and helps regulate body temperature.
\n<\/section>\n
\nEvaporation of sweat cools the body because it requires latent heat, which is drawn from the body itself.
\n<\/section>\n
\nFactors like humidity affect the rate of evaporation. In high humidity, evaporation is slower, making it harder for the body to cool down effectively through sweating.
