Heat index values are quite important 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.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
