Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
