Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
