For folks with chronic conditions that lead to having problems with being cold in bed at night (chills, difficulty with temp regulation, etc), something that has really been helping me is sleeping inside my sleeping bag liner. It's a thin fabric tube that one would normally put inside their sleeping bag to stay extra toasty.
Mine is twenty years old and from the brand Sea to Summit. It's stretchy, so it's not binding. But it's very warm. I use it in bed, just crawl in and sleep normally. It's been a big help recently with the winter temps kicking in.
