Note: The heat index, also known as 'real feel' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high 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.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
