Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. 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. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
