Note: The heat index, also known as 'feels like' or 'felt air temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. 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 important for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
