Note: The heat index, also known as 'real feel' or 'apparent temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
