Note: The heat index, also known as 'felt air temperature' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in.

Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
