Be aware that heat index ratings are designed for shaded locations and minor breezes. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', combines air temperature and relative humidity to represent a human perceived temperature equivalent. 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. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. Stay out of direct sunlight and seek shade between 10 a.m. and 4 p.m., when UV radiation is strongest, but remember that shade devices may not offer full sun protection. On bright days sunglasses that block both UVA and UVB rays should be worn. A hat with a wide brim is extremely helpful, as it can prevent roughly 50% of UV radiation from reaching the eyes.
