It does not, but I know a bit about it.

My ex second H was very sensitive to cold. To the point of having a disease that makes fingers turn red from cold.

And I do not like being in hot rooms.

It was not a good combination - if I opened the window without putting an extra blanket on him while he was asleep, then I was at fault come morning. So most of the time I did not open the window. Sometimes I would go sleep in our younger daughter's full bed (I sleep on that bed now post divorce ), cuddling with the daughter and enjoying open windows (my daughter also did not like hot temperature in the room).

So I can very easily see how the temperature differential would call for separate sleeping quarters. And, sleep issues would call for separate quarters even MORE. I can see that without hesitation.
