Body Temperature - is yours low?

Answered on August 19, 2014
Created August 11, 2010 at 6:19 PM

Body temps are dropping, seems to be a correlation between this and metabolic syndrome/hypothyroidism

Two questions:

What's YOUR Temp?

What's your opinion on Body Temperature Correlations/Causes?

Tyrosine is in meat. Your thyroid needs tyrosine to function properly

I experience cold hands and feet as well but it goes away when i eat a lot. The thing is though, because my digestion is pretty slow i have to stuff myself to get warm. As in its hard to absorb my required amount of calories. Currently Im trying to improve my digestion with more exercise and more ferments.

Always have been a degree or two colder than 98.6. Diet hasn't changed it. I figure it's a thyroid issue I haven't gotten to the bottom of.

The thing is, I don't think many people get cold if they skip protein for one day. That means to me that the protein currently in your stomach and intestines is not the main issue. There would be something in the protein that is digested and retained that is helping with heat regulation. What specifically might that be?

Well I think if the average temps of the entire population are dropping significantly, it probaby is indicative of something specific going on. And that is interesting. Just like the kids are coming into puberty earlier and earlier now, which is probably not good. They are saying obesity may be the driver, but then are getting off track as to what drives obesity in the first place, so research continues to founder on the rocks in that department.

Not sure what you're getting at. The "normal" body temperature for humans is hard to pin down because it varies in a range. If you measure yourself and get an average of 97F for the day, what does that tell you exactly? It could be your "normal" or it could be a result of a disease state or maybe you just skipped breakfast. It doesn't really give you any useful information.

I think you are supposed to wait at least 15 minutes after eating or drinking before you take your temperature, because the temperature of the food, and the action of the jaw muscles will alter the results.

I experienced coldness as a vegan. Cold hands and feet, but especially cold hands. They would never warm up after being wet. This is actually a symptom of long-time smokers, but I never smoked. It's amazing that simply by being vegan I could have that kind of symptom too.

All I had to do was add animal products and BAM! I was warm. SO warm. The first thing I had was a cheese pizza (no meat) and I was already feeling a bit warmer. But then I added lots of eggs and really started to notice. then later meat. Haven't been cold since!

I'm always freezing. I just had my temperature taken and it was 96.8

I feel like I run cold in general, but this has increased since Paleo. What the cause is, I'm unsure. Maybe drop in BF%? Likely a combination of things. I believe Matt Stone said VLC made him run colder and once he reintroduced starch it turned around? I cant confirm at the moment, but I think that's what he said.

I have added starch in more regularly now, and have noticed some improvements. I will try to actually track this and report back.

My body temperature drops when I don't eat enough. It goes back up when I eat more. I often wonder how many people with "low body temperatures" are just not eating enough.

Also, keep in mind that the "normal" body temperature range is larger than most realize: see http://en.wikipedia.org/wiki/Normal_human_body_temperature. I can't really tell you "my temp" because it varies during the day like everyone else's. So the fact that body temperature correlates with anything doesn't strike me as particularly significant; it's at best a very coarse measure of health and worrying about it overly much strikes me as a waste of time.

My two cents anyway.

I think low body temperature is a big indicator of low thyroid, at least from my personal experience. My temp for the past 4 or 5 years has been pretty consistently in the 96's, sometimes low 97's.

For the past week I've been following Danny Roddy's advice (pretty in line with Ray Peat) and I've seen a pretty big improvement considering it's only been a week. My body temp was at 98.2 today and I haven't seen that in a long time. Within the first few days I experienced a warm feeling in my hands and feet which I haven't felt in a couple years. I've been feeling pretty good.

It's too early to tell if it's the right way to go, but it sure does seem like it so far.

I've been charting my temps for some time (first thing in the morning, oral). My average is 98.3, and the range is 97.7 - 99.1

I notice that a starchier, low-fat meal (yams or the occasional GF starch in an open meal) raises my temperature quite a bit. If I eat high fat and very low carb, I get cold after I eat.

For most women, 96 to 98 'F is considered normal prior to ovulation and 97 to 99 'F after ovulation.

My body temp is always around 98.0 upon waking and hovers there for most of the day.. some days after a meal high in carbs it will shoot up to 98.7-9.

I do think there is a correlation between overall metabolic health and body temp, but I'm not really sure how exactly it all works. When I eat low carb I tend to get cold even though the meal is higher in fat. Its all so confusing.. sigh.

I am reminded of an old joke: "I don't know what apathy is and I don't care."

Personally, I think the body temperature/metabolism stuff is about as valid as Homeopathy (placebos can be very effective). I haven't seen any science that jives with the theory. I am prepared to eat crow if someone can show me some evidence.

I've taken mine at diff times through my life and it always ran a bit low, like about 96F, especially during sleep. I do not have any problems actually getting cold though. In fact, I tolerate cold better than most.

Interesting thing is though, that I have never taken my temp since on paleo, so I just now got off my duff and dug out the thermometer and inbetween bites of steak, took my temp and was surprised to see it rachet all the way up to 99.6! I don't know if the steak is making me hot (I admit it, I have a love affair with steak!), but I think that is the highest temp I have ever measured when not sick. I will have to try it again later and see if it is still high. Very interesting! Good question, thank you. -Eva
