Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
