A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. 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.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
