Vampire physiology question

[shapinglight]

We all know the whole 'unneeded breath' thing is silly, right? We do, right?
Vampires may not need oxygen to live, but they do need to breathe in order to speak. Fine.

But does it make sense to anyone else (as it does to me) that their breath would feel rather on the cool side? They have no body heat of their own. They derive it from drinking blood. But does that warm them up so much their breath would be as warm as a human's?

Opinions, anyone?

Someone had a fic once where the problem was that vampires did freeze in cold places, so Spike was having terrible problems on a supposedly romantic minibreak to the Northern lights, and was trying to battle through with enough furs to keep the cold out. (With a decent coat, after all, a snowshower in Ireland at around -2C or something wouldn't be enough to drop you straight down to freezing very quickly if Angelus had spent all day inside with a warm fire, so it would be realistic for him to go outside.)

But anyway, I always thought this fic made brilliant sense, and explained why Buffyverse vampires seem to flock to warm, sunny places with sometimes relatively short nights, rather than spending the winters in Stockholm and the summers in Chile...

It does make sense, and chimes in with what I wrote recently in one of my entries for the Fag Ends Anniversary Comment Fic Challenge, in which Spike told Buffy that vampires sort of shut down and hibernate when they get too cold (except that I think in my head, at the time, I thought he was lying).

What was this story called? Can you remember?

It was definitely a seasonal_spuffy fic... Maybe one of thisficklemob's?

Ah. I'll have to look it up. Maybe it'll give me an idea for what to write this round.

Nothing else has so far.
