Note: The heat index, also known as 'felt air temperature' or 'real feel', comes about by integrating the temperature readings with the humidity levels. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
