In case you've never done it, let your house get into low 40's (F) and it takes days to warm up. The air gets warm fast, but your bed and the floor take a long time to warm up.
When out for some time in the winter I leave things at 14C. (Canadian winters, mind you). Doesn’t take days to warm up when we’re back. And if so - what? People live in places with slightly-above-zero temps without central heating and amazingly they manage to survive. Blankets and jackets are a thing.
