Note: The heat index, also known as 'apparent temperature' or 'feels like', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
