Note: The heat index, also known as 'feels like' or 'felt air temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. 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.
