Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
