Consider that heat index readings are for situations in the shade and light wind. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 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.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
