Welcome Stella, my nose is always colder too, even during a hot flush! My husband and the rest of my family think I'm mad too, play it up, you'll get away with loads!

Hey Stella. I think the reason is because the nose is a very small part of the human body and it's hardly ever covered up at all. But that's what I think. I'm weird and I'm not that intelligent. Nice typing to you.

It's because the nose is the only part that regularly gets covered in ice cream. The body has naturally evolved in such a way as to stop the ice cream melting away - and so maximise the enjoyment of this chilly dessert.

Isn't nature wonderful.

I find my hands + feet get coldest, probably because they're the furthest reaches of my circulatory system + my blood's cooled down a fair bit by the time it gets to them.
Do you have an uncommonly long nose? As in, about as long as an arm or leg?

As cold air is breathed in through your nose it is warmed by the blood vessels inside the nose so that it reaches your windpipe and lungs at body temperature. If you breathe through your mouth in cold weather it feels pretty raw in you windpipe because the air hasn't had this warming done.
This means the nose acts as a kind of heat exchanger and all it's warmth goes into warming your breath.
Also the capillaries in your exposed skin are constricted so there is very little blood at the surface to warm the skin (it would be a waste of heat).

My nose is my temperature gauge. If any part of the body is at less than optimal warmth, the nose will also be cold. If I'm comfy, the nose is too. I figure that's its main function.

As a biology student I can happily say that Spike has got it right :)

Saves me a bit of typing.

Takes a bow.

Thanks Tenshi ;-)

Also, most of your exposed skin has a mass of nice warm meat on the other side to keep you toasty. But your nose is just a few thin strips of tissue with lots of air circulation on all sides. That's too much surface area and wind chill for your tiny nasal capillaries to try to keep warm. Your ears and fingers can have similar problems. So do your toes if they stick out from a blanket.

Maybe you are in fact a dog, in which case a cool, moist nose is a sign of health.

Spike was bang on, its a heat exchanger. Tenchi could see that too. Why did I not think of that. To prove that its true just breathe through your mouth for a while (15 mins for me) and it should warm up, mine did! My nose was cold all the time for years! Don't know what the long term solution is but I am happy to know how to get some control of this problem.

Thanks Spike, well spotted Tenchi.

Have you tried extracting the ice cube?
