Note: The heat index, also known as 'real feel' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold great significance to children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
