Plenty cold here. It was supposed to have got to -4 F (-20 C) overnight. But it’s really sunny this morning.
I think I went in to hibernation mode. I fell asleep on the couch at dark(about 5:30pm). Sometime in the night I woke, the fire had gone out and it was cold. I climbed up to the sleeping loft and slept till after 8:30am.. I never sleep in that late. I’m usually up by 5 am. 
I really appreciate the sleeping loft when it gets this cold. It’s about 20 degrees warmer up there and not as drafty as the rest of the cabin.
If you are thinking of building a cabin, I would recommend a sleeping loft with an operatable window. On nights, when it is not in the negatives, it is often so warm up there that I sleep with the window open. Even with the window closed it’s drafty enough to give me fresh air while I sleep.
When it is really cold, I keep my clothes in bed with me so they will be warm and I can put them all on before going down to light a fire.
I appreciate all the windows down in the main floor when on cold mornings the sun pours in and heats up the cabin.
