As with clothes you were wearing while you climbed, the liner boots are damp - if not wet from the days activity. Energy is required to evaporate the moisture - this cools you down, including your feet. You get cold from it very easily. Also as most people will feel cold if they have cold feet, so you will feel cold even if you are actually warm enough. In ...

Drinking alcohol in a blizzard with potential for whiteout conditions is reckless, irresponsible, and possibly dangerous. Alcohol causes your blood vessels to dilate, which leads to an increased rate of heat loss. A much better source of quick energy would be a food with simple carbohydrates.

So at 5C, with 60Kmh winds, that gives you a feeling of about -2C See here. Not zero, If the air temperature gets to 0C then there's a potential for about -9C. You want to be aiming for a laying system so you can adjust your core temperature with movement, if you stop you'll want something to keep you warm. I'm not sure you have anything like that in that ...

Caveat: Heading out into a blizzard seems an easy way to get killed. Personally I'd only do it in dire situations. Regarding your layers: Cotton stores about 27x it's weight in water. This makes it comfortable indoors or in hot weather, but it also means it will act like a swamp cooler once you're no longer throwing off enough heat to keep it warm. ...

Before the climb As @ShemSeger suggests, most of the work is to be done before the climb itself. You need to stay warm belaying your partner and waiting to climb yourself - if your hands and feet are cold beforehand, it will be hard to warm them up when they are in contact with cold stone. What you can do is: Keep your core warm by wearing warm clothes - ...

Pneumonia is not what you have to be worried about in this situation. It is a serious pathologic condition of the lungs commonly (but not exclusively) cause by viral or bacterial infection. Unless you were previously infected it is not likely to catch anything away from civilization. There is a widespread notion of a relation between being cold and catching ...

The standard expedition stove for extreme conditions would be an MSR XGK. You will likely want to bring a pair of them, along with a repair kit, on the assumption that due to the cold or poor quality fuel you'll break a pump or need to make other repairs. Now, you may be thinking "what are all those people doing with canister stoves on ...

Scandinavia is a good option, the more north you go the better. For me the nature there is more remote, more 'raw' compared to the Alps. So I would think it's comparable with Canada (although I've never been to those regions). If you can choose when to go, why not go during winter time. You can add late autumn and early spring too. In this timespan you ...

Warm Your Core! One thing all climbers have in common, is a big poofy down jacket. Your fingers are only going to be as warm as your core is, so keep your core warm, and that nice warm blood will circulate to your fingers. Only take your jacket off when it's your turn to climb. For extra warmth, drink hot chocolate while you're wearing your poofy jacket ...

I would add that I did Jiri to EBC in Feb 1992 (the coldest time of year?) and found it to be cold (4 season sleeping bag) but manageable. I am just re-reading my diary from the time - and the noticeable thing is that the cold is mentioned quite a lot - but my 'whining about the cold' is ALWAYS related to wind. So make sure you have windproof gear handy to ...

I am presuming this is not a hypothetical survival situation and it can be planned for. I used to regularly walked in wet boots for days, often in near (although rarely below) 0 degree temperatures, although pass hopping we could spend most of a day above the snow line with wet boots. A typical week to 10 day trip where I live you will cross a river ...

In humans not a lot. There are significant differences between blubber and fat. Though blubber is mostly made of fat it has very different composition to human fat. An animal with blubber also uses it in very different ways to the way a human uses fat. Fat in a human is an energy source, not insulation: (blubber)... can comprise up to 50% of the body ...

I would add an extra insulation layer for the morning. A light down or synthetic jacket would help you warm up when you get out of bed. Don't wear cotton pants. Not only will they keep you cold if they get wet, they will never dry, and will be very uncomfortable. When it does not rain, you'd want your fleece to be wind-stopper, or have a windproof jacket ...

Put Heat Warmers in your climbing shoes and in your gloves, put a big puffy on. Jumping jacks, lots of jumping jacks, get your heart rate up and get your blood flowing and warmed up. Climb, the first climb is always the worst! Keep a heat pack in your chalk bag. You'll freeze on the wall but when you get down you'll be hot! Immediately throw on your ...

There are many good answers here, there are also several warnings about the advisability of your journey. One of the more important things to take (that seems to have been overlooked) is your ID, drivers license, dog tags (if you were in the military). As a consideration for others it is important to make it easier for them to identify your body if/when it ...

I just browsed the meta site, and am encouraged to add an answer. I agree with the above answers and comments, especially (1) don't wear cotton pants; (2) carry spare socks and mitts; (3) poly is lighter and warmer than wool when wet; (4) your clothing is on the light side; consider the additions suggested. I'd ADD: a neck gaiter. This is a fleece tube ...

Four season tents should be good for 4 seasons. Winter tents are good for winter. I don't think a tent that is a winter tent can accurately be called a 4 season tent because it's not. Not expert analysis just common sense. What makes a good 4 season tent is the ability to withstand cold and heat. Huge mesh panels on the inner tent for when it's hot that ...

If you burry your bottle in snow it should be less likely to freeze. The snow is a great insulator and burying the bottle completely should keep the heat from escaping. Essentially you are making a quinsy for you bottle (but much less effort!).

48 hours is very definitively too long for your feet to be wet, even regardless of temperature. https://en.wikipedia.org/wiki/Immersion_foot_syndromes From the CDC article "Injury occurs because wet feet lose heat 25-times faster than dry feet. Therefore, to prevent heat loss, the body constricts blood vessels to shut down circulation in the feet. Skin ...

We have experience with ice accumulating on our tent, but we just bang it off manually. We've never had to deal with a tent encased in strong ice. Usually we'll reposition the pegs and ties because the tent has slumped from the moisture and then ice, but we just manually knock any of that ice off too. We haven't had to deal with more than a day or two ...

tl;dr: concrete advice under the horizontal line Agreeing with the other answers, alcohol is best left for later because it can disorientate you. And among strength, endurance, body type, environment awareness, wisdom - the last is by far the most important when surviving. A month ago I was the closest in my life to calling Mountain Rescue (thanks god, ...

The water will either absorb into the sleeping bag materials, and or evaporate, or absorb then evaporate. The rate of evaporation is determined by the humidity inside the sleeping bag, and this is determined by the rate water vapor escapes into the outside air. The latent heat of evaporation of water is around 2264 kilo Joule/Kilogram (629 WH/Kilogram.) - ...

It's a simple calculus: weigh the inconvenience of carrying some extra layers (weight and bulk) vs. the danger of being under prepared. Keep in mind that weather forecasts are only advisory, and conditions can change (sometimes for the worse). When I hike in the mountains (White Mountains, New Hampshire) or backcountry ski, I always err on the side of ...

You're sleeping bag only works if you can get it warm. If you wear too many clothes in your sleeping bag, you're not going to fill the loft of your expensive down mummy with cozy warm body heat. This is what can happen if you're wearing your liners in bed, the bag around your feet doesn't warm up. I think whether or not you get cold toes depends a lot on ...

A couple of additional points which I think have not yet got the attention they deserve. Time is of the essence. I've once seen a report that stated that the average swimmer can make it about 50 meters max in 4°C water before drowning. That is not a lot! Meaning, that if the person in distress cannot hold on to something which helps them stay afloat you ...
