Many people, including my sibs and me, run low always, particularly in the morning. We consider 96º to 97º normal. If we hit 99º, we feel really feverish. But temp. will rise slightly during the day. If you have no symptoms to go with the low temp., you should be fine. Why are you taking your temperature regularly? If you are really concerned, see your primary-care physician. (Google “Low body temperatures”. There are several interesting articles.)
