[pct-l] Keeping a VERY skinny guy warm in SoCAL

[Finley, Graeme]

I believe the theory behind this is that direct heating of the blood
from conduction of an external heat source (e.g. a Nalgene full of hot
water) is an efficient way to warm the body.  The hands/wrists have lots
of blood vessels close to the skin and therefore are a good spot.  One
other area that comes highly recommended is holding the bottle between
the thighs - this provides contact with the femoral arteries in each leg
(which are probably the large blood pumping vessels in the body).

If I just can't get warm, I get very warm water on my wrists for a few
minutes and I warm up all over. I can literally feel the warmth
radiating through my arms and feet and legs, and I stay extremely warm
for a while after doing that. My doc told me about that, years ago. It
definitely works.
