Heat index guidelines indicate values are for light wind scenarios and shaded regions. 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', is a numerical representation of warmth when taking temperature and moisture levels into account. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
