Do you prefer sleeping in a warm or cold room and why?

I was at my bestie’s birthday dinner last night and there was a loooooong and hotly contested conversation about this which I found quite amusing so I thought I’d ask the lovely folks of Groupthink.

ETA: For the purposes of this super important and scientific poll, “warm” means comfortable room temperature where you could take or leave a blanket.

Personally, I’m a fan of sleeping in cold rooms in my jammies under my fluffy squishy duvet and snuggling into my pillows, Winnie The Pooh-style. A warm room makes it so I can’t use my comfy duvet. This is not ideal. So cold rooms for me!
