Note: The heat index, also known as 'feels like' or 'felt air temperature', reflects the feeling of heat when considering both air temperature and humidity.

Heat index values are particularly meaningful for babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. As body temperatures escalate without effective heat release, one might face dehydration threats.
