Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off.
