It is essential to grasp that the heat index's numbers are for shade and light wind settings. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is a composite of temperature and humidity figures to convey how warm it feels. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
