To keep my feet warm in bed while camping, just before going to bed I put warm water (not boiling) in my Nalgene bottle and put it by my feet in my sleeping bag. By the time I get thirsty in the early morning, it’s cool enough to drink and my feet are still pretty warm. Boiling water could rupture the bottle and/or burn you.
