2 degrees is required to MAKE you shiver. This (along with reduced blood flow to your skin and brown fat cells becoming active) prevents it going much further. You need to lose 17C to die.

My fingers don't mind the cold, they in fact go RED to increase blood to them to prevent frostbite.

The body does shiver for a while to keep warm, but there are limits, and
that seems to be governed by your core temperature dropping by nearly 2
degrees. Of course prolonged cold make the body keep the blood inside the
bodies main organs, shutting circulation off to extremities. if this goes
on too long tissue dies, ie frostbbite etc.

So its all in the timing and the core temperature. Of course if your
clothing starts to get wet as well and there is a wind, then you have far
less time to do something about it.
