Note: The heat index, also known as 'felt air temperature' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
