Note: The heat index, also known as 'real feel' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
