Heat index values are quite important for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced.
