Yea with those temperatures hyperthermia will set in in about 10 to 30 minutes without some kind of thermal sleeping bag or something. Something reliable to keep them warm. I suppose if they have something like that it could be fine? I just think it might be easier to stay in the cabin though/ I can see the gods taking it in a bad way? Like a sign of disrespect? Might be a stretch but that's one way to get them inside with them still having that feral nature?
