Note: The heat index, also known as 'feels like' or 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. 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.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
