Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
