The standards for the heat index are set for locations in shade and under light breezes. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear.
