Note: The heat index, also known as 'feels like' or 'apparent temperature', determines the feeling of heat when you account for the relative humidity. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important 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.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
