Heat index values are extremely significant for children. 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.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
