Do you prefer to sleep in a cold room or a warm room?

Well, I never measured the exact temperature but during the winter months my room can be about 13-14 degrees Celsius. Maybe less on a really cold day. And with an open window it can be pretty cool. I much prefer when there's plenty of fresh air circulating. I like to snuggle up under the blankets and drift off.

My room often goes up over 23 degrees Celsius or higher during the summer and I hate it. Can't sleep properly. I live in a cool country, but the room faces the sun and the windows are double-glazed, so it ends up absorbing all of the heat. Which is why I'll easily sleep 8 hours in the winter but maybe only 4 in the summer.
