And I'm tired of it and I can't get warm. Is this a PN thing, anemia, or possibly something else?

I have shoes AND socks on, pants, long sleeve shirt. Sitting in front of space heater, outside air temp 52, maybe 68ish in house.

My skin is cold to touch, feet feel like ice blocks. Hands ok.

CBC 2 weeks ago unremarkable.

Ideas/suggestions?

I can be from many things. Autonomic dysfunction, PN, thyroid...and probably others I haven't mentioned.

I have severe autonomic neuropathy so I'm sure mine is from that. Sometimes I just can't get warm.

This will sound counter intuitive but I just started doing a metabolic trick I saw on Dr. Oz's show by chance:

http://www.doctoroz.com/videos/four-...fect-body-pt-1

http://www.doctoroz.com/videos/four-...fect-body-pt-2

http://www.doctoroz.com/videos/four-...fect-body-pt-3

What these 3 videos really show are metabolic stimulating tricks to get you to burn fat for "energy/heat".
The brown fat in your upper body is designed to create heat when you are "cold".

The third trick uses grapefruit juice and for those on drugs, one cannot use the juice. But the concept of the "binge" or eating more food one day a week when dieting fools the thyroid as well. He explains this in the book (which I immediately bought).
Chronic dieting Ferriss says turns down production of T3 in the tissues (starvation mode), and promotes storage of food eaten as fat. There are other new diets using this principal as well.
The 17 days diet is one.

I've been doing the ice once a day to start, and there is a tremendous increase in warm body feelings. It has been so cold this winter here and I was SO uncomfortable! But just doing ice packs on my chest and neck once a day, and now I am not cold anymore! I had to change clothing during the day and at night sleeping! It seems counterintuitive to use ice to get warm, but it does work!

Doing this reminds me of the sauna users in cold climates. We've all seen movies/videos of them running out and jumping in a frozen lake after a sauna, and I seem to recall none of them were heavy or had alot of fat on them! Makes one wonder?

Remember, you cannot use grapefruit if you are taking RX drugs. Many interact seriously with grapefruit.

.....you cannot use grapefruit if you are taking RX drugs. .....

I know, and I used to love grapefruit juice.
Preferred it over orange, hands down.
My wife regularly has a 1/2 grapefruit for breakfast
so there's always some in our fridge.
I don't think I've had grapefruit or a glass of grapefruit juice
in 12+ years ..... & I miss it.

I am only using 4 oz of unsweetened Ruby Red juice a day.

So far I am safe medically (I stopped using my diltiazem).

There is a paper out there showing grapefruit eaten before meals increases insulin receptor sensitivity.

In the book however, he says 3 oz of fresh squeezed unsweetened lemon juice lowered blood sugar peaks by 10%.

On the show, it was changed to grapefruit. (book had already gone to press).

All citrus has been implicated in having reactions with drugs however. But grapefruit has the largest effect I guess.

He also tested vinegar and apple cider vinegar and neither had any effect on blood sugar levels.

How's your indoor humidity? Dry air can feel a lot colder than moist air. Optimal humidity is 30%-50% for most folks, and space heaters can dry things out pretty well. Most folks who burn wood for heat keep a pan or kettle on the stove to keep moisure in the air. However water & electricity do not mix...

How's your activity level? I get cold when I'm inactive for too long. Any kind of activity helps - even in spurts. Up & down a flight of stairs once or twice, walking as briskly as conditions allow, flailing arms.... anything cardio that gets your circulation moving.

Ah, our neighbor has the best pink grapefruit tree! I can't have them anymore, darn meds! I have avoided any citrus for years, even the tangerines from my own tree, too much acid.

Our humidity in winter can get into the 40s, usually higher, and summers are like a sauna.

But I will try the other suggestions, thanks!

Typically, I am warm. But during a dysautonomic attack, I can vary between hot flushing, or get very cold. My extremeties are like ice. I also have raynauds and this can cause coldness in my hands and feet. The best for me is to get into bed preheated with an electric blanket. This seems to help tremendously.

when i feel cold a long hot shower does the trick.

Aussie....that 40% is outside, yes? When the air is heated from 52 to 68 the humidity % is going to go DOWN! if you can get your hands on a gauge to measure YOUR inside humidity you may find it lower than the optimum!
