Heat index

Heat index values are typically calculated for conditions of shade and a light breeze. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to 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 body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
