Note: The heat index, also known as 'real feel' or 'felt air temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels.

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 hold particular importance for children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
