Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation.

Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
