Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration.
