Heat index values are particularly meaningful for babies and toddlers. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced.
