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.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
