Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. 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 extremely vital to 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.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
