Note: The heat index, also known as 'apparent temperature' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are of high significance for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
