Note: The heat index, also known as 'apparent temperature' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
