The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children often do not understand the need to rest and hydrate.
