Understand that the heat index values take into account shaded locations and mild winds. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a value derived by merging air temperature with the humidity to convey how the climate feels. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
