Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
