With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. 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 highly important for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
