First,excuse my english, it's not my fist language).
This happens to me too, not every night and I can't establish a pattern. I have a difficult time getting my body warm enough to got to sleep but then in the middle of the night my body temperature rises (especially on the torso)but when I kick the covers and then I get terribly cold again.
During the day I'm usually cold (especially hands) and have been told that I have Raynaud's Syndrome.
I have read that having FATTY LIVER can cause overheating of the body, especially the face and torso.I have associated this also when I consume a lot of sugar...but, then again the fatty liver causes sugar cravings.
I'm glad I found this discussion board and hope to find a good explanation for all this111
