Note that heat index values are valued for light wind and location in the shade. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Rising body temperatures due to excess heat retention could signify impending heat disorders.
