comment Will drinking lots of water in the day(s) prior to a long trek mean I will need less water on the trek?
@BenCrowell. Alcohol isn't diuretic? I take it you've never had a hangover, then?

@Roflo - indeed. My problem is I'll drink a doppio instead of a half pint of water. So more coffee == much less water :(

comment How fast do you lose heat in cold water immersion?
@Escoce The question text I quoted conflicts with question title that you've quoted :( Everythng you say is correct (so +1 from me) but I think you may be answering the wrong question.

comment How fast do you lose heat in cold water immersion?
@njzk2 Indeed :) But the question body is specifically asking "How long does it take after immersion into cold water to develop hypothermia?". But you're right not care unduly about Hypothermia, as it almost certainly won't be what kills you.

@PaulD Do you have any links for those? Most of my google searches seem to back up the '30 minutes' figure, give or take.

@ShemSeger "Your body will warm the water immediately around you" Yes, that's how partly how wet suits work. But I'm not aware if that effect makes any difference without something like a neoprene barrier layer. You'll be moving in the water anyway to stay afloat/swim/get out.

"Any longer than 10 minutes in the water and you will no longer have the strength nor ability to hoist yourself out of the water". Agreed, but that's not hypothermia, it's cold incapacitation. outdoorswimmingsociety.com/swimming_outdoors/embrace_cold/…

comment Hypothermia Prevention - Post Ice Water Fall
Good answer :) Interesting stuff re shared sleeping bags here. rendezvous.nols.edu/content/view/1677/964 - basically can inhibit the casualty's shivering response which is one way the body warms itself.

@njzk2 I was surprised too. But I've added a few references. I don't know enough about this stuff to risk making it up.

comment Hypothermia Prevention - Post Ice Water Fall
@imsodin : Loss of dexterity is cold incapacitation ,not hypothermia. Quote from your link: "it is impossible for a victim to become hypothermic in less than 20 to 30 minutes immersion in cold water."

comment Hypothermia Prevention - Post Ice Water Fall
Confused: Do you mean how to treat mild hypothermia (preventing it turning into severe), or how to prevent mild hypothermia in the first case? Or, do you mean how to prevent a casualty from ALSO getting hypothermia?

@Escoce Exactly. He's in COLOMBIA, not COLUMBIA. There's a typo in your post.

Please don't do this to an eVent jacket :) (and he's in Colombia. not Columbia - very few rubber trees in DC)

comment What are the pros and cons of a digital altimeter over an analog altimeter for backpacking?
@ShemSeger - many GPS devices have built-in barometric altimeters to improve the GPS accuracy for elevation. Both 'sensors' get used together.
