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.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
