Heat index values are of high significance for children. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
