Heat index values are especially vital to 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.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
