Note: The heat index, also known as 'felt air temperature' or 'feels like', determines the feeling of heat when you account for the relative humidity. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. 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 gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
