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.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
