The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
