My freezing feelings are eliminated at night by an electric blanket. I'm afraid to have it on all night, so it's on a timer. The bed is warm when I get in, and the timer turns off about 15 minutes later. I usually toss and turn for 30 seconds before falling asleep in my wonderful warm bed (Smiley face!).
To peel myself out of a warm bed is torture. My physical therapist taught me some vigorous exercises to do lying on the bed. About 30 minutes of this warms me up enough to face the Michigan winter-cold floors. I wear a long down vest over my usual clothes. If I get cold during the day, I get up and walk outside if there's no ice, or just around the house. I can't walk very far, but I can do short distances often. Warms me up and seems to help balance and neuropathy. Thanks for posting your question! All of us frozen people will benefit.
