Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

Clothes that are both tight-knit and comfortably loose are prime choices for sun protection.
