Heat index values are extremely significant for babies and toddlers. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
