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.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
