Observations indicate that the heat index values are for shady locations with light wind. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. 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.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Experience reduced UV exposure by about half when donning a wide-brim hat.
