Note: The heat index, also known as 'feels like' or 'real feel', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant 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.
