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.

Uncle Peter made this incredible statement:

"This is a fact. -20C air does not make you cold, . You might shiver if
you were naked, but the shivering will stop you getting any colder".

To me, it sounds like he's talking absolute bull**** and he should be
sent to the funny farm, but is there an element of truth in what he
said?....Anyone know?
