For clarity, heat index numbers account for light winds and areas under shade. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance 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.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
