Heat index values hold particular significance for children. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
