Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
