Note: The heat index, also known as 'feels like' or 'apparent temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
