Note: The heat index, also known as 'real feel' or 'feels like', 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. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold great significance to children. 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.
