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.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
