Note: The heat index, also known as 'real feel' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. 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 evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
