Factoring in the heat index, values are geared towards shaded areas with light breezes. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an aggregate value of air's warmth and moisture to show the human-felt temperature. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.

Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes.
