Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation.
