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.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
