Heat index values remain especially vital 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 primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body.
