The metrics for the heat index are tailored for both shady environments and light winds. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. 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 largely significant for babies and toddlers. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Remember, however, that shade structures may not provide complete protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
