Note: The heat index, also known as 'real feel' or 'feels like', gives an indication of how one might feel in terms of heat after considering humidity. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
