Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down.
