Note: The heat index, also known as 'feels like' or 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. 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 hold great significance to children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
