    My temperature has nearly always been 98.3°F, but I've not taken it in a while. Last night about 10PM I got a little bit of the sweats and took my temp and it was 97.6°F! I have never ever had a temperature below 98.x°F in my entire life. It freaked me out.

    It was 97.9°F when I got up, then later rose to 98.2°F, then down to 97.9°F, and now it's up to 98.3°F. I trust the thermometer. It's a Vicks Rapid Read +/- 0.2°F oral thermometer I have had for a while. I double-checked with an old style fluid-filled one last night and it read about 0.3°F lower than the electronic one. My oximeter says 98%.

    It's been a weird summer for me. I've not been motivated to do anything. My yard is overgrown and I have other pressing stuff I've just ignored. I wonder if all this bladder/catheter stress has caught up to me. The point being I have been more sedentary than ever in my entire life. That likely has something to do with a lower temp. Or it might have been a passing bug (I don't get the flu, every couple of years I just get tapped on the shoulder with the sweats for a day or two and then it moves on.) Of course, all the medical websites have been updated so that Hangnail=COVID, as does a low temperature.

    I called my doctor's office and they did not seem concerned as long as I'm over 96°F. I have an appointment for the 14th (unless jury duty conflicts.) If my temp goes back up near normal I'll cancel it. My mother and both sisters had thyroid issues...that's the first thing that came to mind, given my malaise along with the lower temp, and the reason I asked for the appointment. Maybe I should just get in motion...

    What causes a lower body temperature? In my experience as a paramedic, I'd say death. Have you checked for a pulse recently?

    More seriously...

    Looking further, thyroid conditions seem to be suggested for people who aren't out in cold weather. Others include:
    • Underactive thyroid
    • Low blood sugar
    • Circulation problems
    • Dehydration
    • Vitamin deficiency (iron, B12)
    • Sepsis
    • COVID-19
    I'm not a doctor and I don't even play one on TV.

    My first thought was death, but my lips aren't blue...and my oximeter says 98%.

    I saw a list similar to the one you posted. The only thing that might apply is an under-active thyroid (which is why I wanted to see my doc) or COVID-19. The CDC says "fever or chills" for the Fauci Flu. I don't have any other symptoms...I feel fine, just lazy.

    I wondered if so much slouch time might have reduced my metabolism, coupled with extended time in the air conditioning (at 73°F.) I know that the average temp of humans is now lower than 98.6°F because our metabolisms have slowed down due to inactive lifestyles, but not that low.

    It freaks me out. I have never seen 97.x on a thermometer before. I'll take my temp when I get home from my appointments tomorrow and see if being outside heats me up. And I'll do my oximeter again just to rule out my being in a past tense state.

    My temperature is 98.6 degrees and I don't even have a thyroid.

    It’s a dunno kind of thing.
    When temperatures had to be taken for getting into the gym, a doctor’s office etc (covid-19 era), mine always ran about 97.5-6 and Yvonne’s nearly always ran lower than mine.
    I was checked at the doctor’s office a couple of months ago and it still ran 97. something.

    Just for kicks and giggles, I’ll take the thermometer with me to the gym tomorrow and check it a couple of times during my workout.

    I would think with your workout routine that your metabolic rate (and therefore, temperature) would be on the high side. Of course, those non-contact thermometers have an error rate of ±0.5°F.

    I got up and emptied the dishwasher and did some dishes then started putting dinner together and my temp went up to 98.8°F and then 15 minutes later it was 98.6°F. Who the heck knows? I crashed for a few hours after my eye doctor appointment yesterday and I figured is was from the weirdness of having my pupils dilated and then driving/shopping afterwards. If I crash in the afternoon like that, it's usually only for an hour, not 3. Maybe I picked up a little bug. But as I said, I've never had a low temp bug before.

    Thyroid would be the first thing I would check if the low temp reoccurs, and be sure to ask them to do a thyroid antibody panel when they check your thyroid initially just to rule out the weird stuff.

    Mine has always been low, sometimes down to 95, especially in the winter when my body is cold. Maybe I am a Starseed ? They all have low temperatures , according to what I have read.

    My temperature runs about 98.3 and sometimes lower. My thyroid TSH has been on the rise for years. It is 5.14 now. I feel sluggish and lazy a lot of days. I just figured it was my age.:confused: The doctors don’t seem to say or be concerned that much about my TSH. But once, when my thyroid was around 4.0 a PA put me on thyroid pills and I thought I would lose my mind!! I took them for a week and went off of them.

    You have to wait at least 15 minutes after eating anything to get oral temperatures. Did you drink a cold drink 14.9 minutes earlier? Under your armpit usually measures about 1 degree cooler.
