From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for 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.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
