Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature.
