Note: The heat index, also known as 'real feel' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
