Heat index values are highly critical for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
