Note: The heat index, also known as 'feels like' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
