Heat index values are of high significance for children. 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 innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process.
