Thanks a lot. Sleeping in the cold with a blanket is not a problem for me. My gripe is the period between dinner and bedtime. Body slows down, hence I can't heat myself even with warm clothing if the room is cold. To keep warm, I need a kind of blanket, which impedes my mobility a lot.

Also, feeling cold at night lowers my mood, and I don't want to do anything. However, I'm fine during the day when my body's running at its usual. I live with a t-shirt all year round, even.
