Down comforters are great for this! AND...they don't use any energy! Like sleeping under a warm cloud....they heat up instantly and just throw your own body heat back at you. Best investment I've ever made!We keep the bedrooms cooler and just add more blankets. If you are a chilly willy - turn on an electric blanket long enough to pre-heat the bed then turn it off to save the power. Your body will keep the bed warm as you sleep. Also in the olden days folks wore night caps. A nice little stocking cap keeps you head cozy and your "do" done.
If using electric blankets, they say a heated mattress pad is more efficient than a blanket.
