It is crucial to understand that heat index figures are for shade and gentle wind conditions. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', offers an insight into how hot it feels when we factor in moisture content. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. 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. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
