Heat index determinations are made taking into account the shade and light air movements. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', gives an indication of how one might feel in terms of heat after considering humidity. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
