Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
