Note: The heat index, also known as 'felt air temperature' or 'feels like', binds temperature metrics with humidity values to give a sense of the actual warmth. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
