Heat index values are typically calculated for conditions of shade and a light breeze. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
