In terms of the heat index, values are set with light wind and shade conditions in mind. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', binds temperature metrics with humidity values to give a sense of the actual warmth. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly. Take note! The UV strength of the Sun elevates when reflected off water and sand.
