Heat index values are especially crucial for babies and toddlers. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
