This seems presumptuous to me. Living in cold climates does not necessarily correlate with being cold more than people living in warm climates.
I grew up in Norway. The coldest winter I experienced saw 3 weeks of -30 celsius. I've lived in London the last 22 years. I didn't freeze more in Norway. We had better insulated houses, and far better winter clothes, because we needed to. And so if anything I more frequently get "caught out" and have to add extra layers of clothing etc. in the UK because you can get away with not being prepared for a cold winter here, while in Norway you will have a proper winter coat etc.
