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.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat.
