The standards for the heat index are set for locations in shade and under light breezes. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', binds temperature metrics with humidity values to give a sense of the actual warmth. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. As body temperatures escalate without effective heat release, one might face dehydration threats.

Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear.
