Note: The heat index, also known as 'feels like' or 'real feel', integrates the air's temperature and its humidity to showcase the felt temperature by people. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.
