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.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
