Note: The heat index, also known as 'felt air temperature' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
