Heat index

Always consider that heat index estimations are for light winds and places in the shade. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. 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 remain especially vital for babies and toddlers. 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 normally cools itself by perspiration, as evaporated sweat carries heat away from the body. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
