Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
