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.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.
