Note: The heat index, also known as 'apparent temperature' or 'real feel', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
