Note: The heat index, also known as 'feels like' or 'felt air temperature', takes into account both air temperature and humidity to illustrate what people actually feel. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
