Note: The heat index, also known as 'apparent temperature' or 'feels like', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
