Note: The heat index, also known as 'apparent temperature' or 'feels like', determines the feeling of heat when you account for the relative humidity. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. 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 of high significance for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
