It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. 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 primarily vital for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
