Note: The heat index, also known as 'feels like' or 'real feel', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are primarily vital for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
