I often come to southern Italy for Christmas and while it’s great for everything else I don’t know how to deal with the temperature. It’s around 5-10 degrees warmer than at home but it seems so much colder. The apartments are not heated at all or just barely. So I spend the day constantly under 20 degrees besides showering or being in bed under the blanket and the cold creeps into the bones. At home in Switzerland it might be close to 0 outside but inside it’s 20-25 degrees and I can handle that much better. Got a full-on cold now and feeling totally sick. 
How are you from European south handling that? https://ik.imagekit.io/lens/media-snapshot/2d0d590498cf29fcc7b75340a08068e197b991707181ae53934c9fbffcdade2d.jpg
