In the scope of the heat index, its values resonate with shade and light wind conditions. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'real feel' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

The reflection of sand and water increases the UV dose.
