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.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
