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.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
