Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
