Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to 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.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
