After 8 years of marriage I have FINALLY uncovered the mystery of all mysteries. I have a habit of revolving from sweating, being extremely hot at night to a dramatic change to freezing, shivering, I am in the Arctic pole cold while sleeping at night. For years I could not uncover the secret to my dramatic menopausal type fluctuations at night. While laying in bed the other night, it just magically came to me. The answer to my infliction! No, I am not premenapausal, No, I am not withdrawing from drugs I never took, No, I am not a chronic TB patient! I am married to a man that constantly gets up in the night and comes downstairs for a snack. So, I have concluded that (and discovered through a night of restlessness) my husband wraps his arms around me to go to sleep thus causing a large amount of combined body heat (causing me extreme HEAT) he then wakes up and goes downstairs to eat (source of my heat is now gone) which I then start to feel chilled, and then he finishes his snack and returns to bed to once again WARM me with his body heat. This is not just an activity that he does once in the night. He gets up SEVERAL times a night. Problem solved! I now know WHY I am a temperature mess at night. Am I just discovering that my husband has a bad habit of waking three or four times a night? Absolutely not. I discovered that bad habit the first week we were married. The temperature fluctuations at night are something that I am just discovering...........It is true that you learn something new everyday.
