Metrics for the heat index primarily focus on shaded spots and light wind conditions. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
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. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat.
