Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a measure of how hot it feels when the actual air humidity is factored in. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. 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.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
