Heat index's context suggests values are appropriate for shady areas and slight breezes. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. Sun protection is enhanced with clothing that boasts a tight weave yet offers a loose fit.
