Note: The heat index, also known as 'apparent temperature' or 'feels like', joins air temperature with relative humidity to produce a temperature perception for humans. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance 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.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
