Records show heat index calculations are tailored for shaded regions and mild winds. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
