Reusing hand warmers

[DougPaul]

Skiguy's post reminds me of another factor--tight clothing. (I just read a book involving winter Arctic travel--this issue is absolutely vital there... The author mentions a temp of -98* at one point.) Make sure that you don't have anything tight around your wrists (eg mitten or shell elastic), hands, ankles, or feet--it can reduce the circulation. I suspect that elastic socks could have similar effects... Tight boots (or stuffing too many socks inside one's boots) are known to result in cold feet.

BTW, it is also a good idea to take rings etc off in case your fingers swell.

Who cares!

But I do agree with the not too tight comment.

Skiguy, I tried the wrist thing but it did not work for me.

You must have tight pipes!

This is about the point where spit and other bodily fluids must freeze in mid air if not sooner.

Actually, it would matter to me. Fahrenheit and Celsius have diverged, somewhat (slightly) considerably, at the -100 range.

-100F = -77C

-100C = -148F

The lowest recorded temperature is -89C (-128F) [ref] so I assume we're talking -98F in this case. Despite my affinity for the cold I can imagine myself being somewhat unhappy with -100F but extremely unhappy (possibly superconducting!) at -150F. Note that the temperature on the surface of the sun is upwards of 10,000F.

Way beyond.

I had guessed that he was talking F, too. In practice, it doesn't matter to me because I plan to be elsewhere any time the temps get anywhere near -98, F or C.

BTW, his sleeping bag was only rated to -50F.

BTW2, the book is "Conquering the Impossible", by Mike Horn. A worthwhile read, IMO.

And to bring this back on topic, he was having problems with freezing fingers too.

So you mean if you have tight pipes like Tom your in big duda way before minus 98?
