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.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body.
