Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
