Note: The heat index, also known as 'feels like' or 'apparent temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. 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. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
