Is it normal to suddenly feel cold so easily at mild temperatures?

It was twenty one degrees Celsius today. Once, I would’ve just worn a long sleeved, light top. Today I wore a thick cotton turtleneck. It was warm enough for me. My mum wears long sleeved light tops, still. Is it normal for some people to become hypersensitive to cooler temperatures?
