Heat index's context suggests values are appropriate for shady areas and slight 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 'feels like' or 'apparent temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. 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 particularly relevant to children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
