Can walkers die from hypothermia?
So, judging from episode 5's slide of episode 2, snow will arrive in the game, and thus it will get cold. Most walkers aren't very warm dressed, hell, some of them even have their clothes ripped i think, so i wonder, is hypothermia, death from an extremely cold temperature, a threat to walkers or are they immune to it? Discuss!

Maybe if the brain gets frozen for a long period of time it will do enough damage to kill them off.
On the other hand they might just come back to life when they thaw out. I don't know.
If walkers can't regulate their body temperature (which seems likely -- if they were warm-blooded, they would starve much more quickly) then any temperature below freezing would eventually result in the brain freezing solid, destroying it. So large parts of the world should be mostly walker-free after the first winter. I don't think that's the case, but I don't know the comic's explanation for why it isn't.
I don't know if hypothermia really affects them but if temperatures stay sub-zero for a while, I'm sure that they would actually freeze solid since they don't have any body heat. That would probably kill them.
Zombie's can't get hypothermia Lol. In the comics it was snowing and the zombies still managed to try to kill Rick's group. They get hungry though.
Since they are already dead, they can't die from hypothermia.
Their blood is already coagulated, so that can't freeze. They don't have a circulatory system anymore.
And the brain tissue though "alive" enough to reanimate the walkers, is immune from lack of oxygen. I can see the brain freezing by the surrounding fluid encasing it, but I doubt it would kill them. Probably just put them in a dormant state.
Good question original poster!
i dont think so.they are indefatigable.
As seen in the comics, they can freeze but when it gets warmer they start moving again.
I don't know if we should analize this from such a scientific or medical perspective. I mean, the way the Walking Dead world is, humans by themselves are quite a threat, but I don't think the writers would just eliminate the walkers.
I did read in the Walking Dead Wiki that low temperature could make them slower and therefore less dangerous (no mention of hypothermia or death from the cold, though). However, I think that the more they rot, the weaker they get. Since people decompose slower at low temperaturas, the walkers in a cold area would be better... "preserved". So you can justify pretty much anything if you want. We'll just have to wait and see what happens...
