Hmmm are you wanting a normal adult or a normal temperature? lol

The "norm" is 98.6F statistically speaking. Various body sites of readings, and type of thermometer may vary the intended reading and should be addressed via the directions on the package!

With that said, MY norm is 96.8F. (Talk about the looks I get from nurses and doctors who think I have it backwards when I tell them!) So when I have a temp of 99 F I HAVE A HIGH TEMP!

Food, the process of digestion will change your temperature... hot food or cold. (And not everyone reacts the same way: if I drink hot liquids, I get hotter. My mother, however, can drink hot liquids and her body kicks in to cool her down!)

Outside environmental temperature will also change your body temperature and readings...

I agree with the idea that if you are taking your temperature that often and worrying about it that much, THAT is the symptom you should be treating, not your body temperature.
