Factoring in the heat index, values are geared towards shaded areas with light breezes. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
