Up here in my neck of the woods you can't adapt to the cold snaps we get. I remember a few years ago it got to -50F with an -80 wind chill. You can't adapt to that. You just stay the hell inside. If you have to go out you have to make it as quick as possible or you will get frostbite in about 5 min.
You can adapt to that too if you have to work outside or are into winter camping. I remember skiing in a -70 below wind chill.
