Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'real feel' or 'feels like', offers an insight into how hot it feels when we factor in moisture content. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. 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 especially vital to children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
