Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
