That is really low - I only had one low like that once,when I had a really bad sunburn. Are you sure your thermometer is working right? They can go haywire. Did you recently go anywhere on a vacation and get sunburned???
I agree with Sunlover that 95.5 is abnormally low...
Apart from the fact that this thermometer may be faulty, possible causes could be:
Overuse of alcohol
Certain medications (are you taking anything new?)
Hypothyroidism.
What kind of thermometer is it? My daughter went to the doctor in September for a school physical and a shot and they took her temperature and said it was 100.5! Then started asking is she felt sick or whatever (she's 16, so she'd KNOW!) She said no she wasn't... then I told them to take MY temperature and I got 100.4! (I absolutely wasn't sick!) so the thermometers COULD be off, in either direction, new or not.
My normal temp always runs between 96 and 97.5. SOme people do have a lower body temp than others. I also know when I get a fever, at 99 I feel like crap.
Well, not that I am a doctor (I am a CMA), but I will give it a shot here. Normal temp is 98.6. You have 95.5. Your temp can go down if you are on certain medication, you have been under stress lately or you are feeling ill. True, the thermometer could be defective/faulty (even if it is new), so no need to panick just yet. My advice to you (if you are concerned) is to call your doctors office, explain your situation, and ask to schedule an appointment for a CPE. It can't hurt, and I am sure that will make you feel at ease just a bit.
a low body temp could be an indication of hypothyroidism. do a search on that and see if you have other symptoms that come with it, i.e., fatigue, weight gain, dry skin etc.
