A year later, I finally write my response to Skater's post. <img src="/images/graemlins/crazy.gif" alt="" />

Question - Would it make sense to put a 8x8 inch (or so) piece of the mylar type emergency blanket inside [a wool watch] cap to help retain body heat, or would this have a negative effect on a person suffering from hypothermia?
I tried this after reading this post last year. It kept my head toasty warm! I did it occasionally, but only on very cold days. Sometimes, I just wanted it a tad cooler.

As for hypothermia, I don't know how important the head is versus the body. Speaking purely from a common-sense perspective (always worth some healthy skepticism in the medical arena), I myself can only assume that anything that keeps any part of you warm(er) must be at least partially helpful in contesting hypothermia. Does anyone have anything worth adding regarding that?

Stay safe,
