Understanding the heat index involves considering values for shaded locales with light wind. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', reflects the feeling of heat when considering both air temperature and humidity. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
