Apologies if this has already been asked before, but it struck me today that I don’t know the answer to this and I couldn’t find it after trying to look it up.
Could anybody explain why warm-blooded animals, like humans, need to stay warm to survive? It looks like death by hypothermia is caused by the body desperately trying to maintain core temperature, but why is that so important in the first place? It’s not like you’re at risk of your blood freezing in your veins, so I’m puzzled. I’d be super grateful if anybody could explain why maintaining body temperature is so critical!

Tissue does actually freeze in extreme cold. Blood, warmed by the chemical activity in the body distributes heat to keep that from happening, yes?
