Probably the best thing you can do to acclimate to the cold is to live in it. Yeah, you can say that sounds simple and it may be hard to do, but it's the best way. I live in an area that gets fairly cold in the winter (as much as -40C/F), and I'm used to it. I don't think 27F is cold at all. Many of your suggestions are along this line of thinking, but ...

How cold are you talking about? When you woke up, was there ice on your tent? Or was it 50F outside? Anyways, to sum it up, sleeping bags generally boil down to this tradeoff: Pick Two: Warmth, Small Size, Low Cost If you are car camping, you should be able to find sleeping bags that will go down to 15F for $50-$75, but they will occupy well over 40-50 ...

Some general rules: layer system also for the hands is a good idea but those gardening gloves won't work pretty well better use inner liner gloves (wool or even a softshell glove) and a warm mitten as the outer layer to avoid cooling off use hats (again use a layer-system) including a warm winter hat which covers the ears (also see this about heat loss ...

I'm going to assume and interpret a little, and forgive me please if I put words in your mouth. What you really seem to be asking is: "Do I have to spend mad cash to stay warm?" I would say, in 50F (10C), certainly not! With each item, I give my "cheap", and "good but costly" options (I have no associations with any company) Make sure you have a ground ...

A sleeping bag is like any other purchase, you'll get exactly what you pay for! Unfortunately, sleeping bags are used in many different situations/climates. A sleeping bag you carry and use in the summer months when the lower temperatures are 60 or 70 degrees at night, won't begin to work when you camp in the fall/winter/spring and the temperature lows are ...

a two layer winter hat to protect your ears a good winter jacket (long enough) supporting -40ºC (-40ºF) winter boots a two layer gloves a scarf For the intermediate layer: The key point is to not sweat. Depending on your body, you should choose the appropriate "heat level" intermediate layer. Some shops will have different categories from very cool to ...

That lean-to in the link looks like it would shelter from all but the most wind driven rain. If you pack a cheap vinyl poncho that should take care of most situations. They are light enough that you can pack a second. What is the temperature rating on your sleeping bag? 15F/-10C will probably be more than warm enough. If you are carrying a summer bag, you ...

If the suggestions in Everything's answer don't work, try these heating options: Heated gloves (I have linked to an example) Hand warmer packs to tuck into your gloves My wife has Reynaud's which leads to poor circulation in fingers and toes, so needs to use these solutions on occasion, and they are very effective.

Yes, you should seek medical expertise. From healthcentral.com: When the skin has thawed and rewarming is complete, cover the damaged skin with bandages and warm clothing. Contact your doctor or go to an emergency room.

The phenomenon name is cold diuresis. From thefreedictionary.com: [cold diuresis] occurs in hypothermia as a result of peripheral vasoconstriction, hyperglycemia and decreased renal tubular absorption. You can easily find articles and papers on the subject on the Internet.

I am not sure why you want to do this, but I have noticed that in a group of people in cool (not cold) weather eg 5 C which is 41 F, those who live in places with a very cold winter (rural Ontario like me, Winnipeg) are not even zipping up their coats while those who live in year-round warm places (Texas) are shivering and complaining and borrowing gloves. ...

The key to cold weather clothing is viewing it as a system. The base layer of the system wicks moisture from the body and provides a small amount of insulation. The middle layer(s) of the system provide warmth and wind protection. The outer layer provides protection from the elements. That being said, a proven system for the temperature range you're ...

IMO you totally don't need a tent. Plenty of people, including me, prefer to sleep out under the stars even if there's no hut. It can be difficult to sleep with a wind blowing across one's face, but that won't be happening inside the hut. It's also off the ground, so you won't be losing heat into the dirt. Yes, the temperature inside will be the same as ...

I have friends who swear by silk inners. They are thin, so can be worn under other gloves, but are extremely warm for the thickness. Combine these with windstopper outers - as mentioned elsewhere, layering is good practice. On the downside, silk is really expensive, at least where I live. On the upside, silk lasts a long time and doesn't get smelly.

You could do worse than to research Wim Hof, his accomplishments, and his training methods. TEDx Amsterdam video YouTube channel Daredevils show featuring Wim Hof Have fun. :o)

You actually don't need to go outdoors to get struck by Hypothermia. But you can suffer from it on a trek where you don't have a proper campsite, camping equipment, or good clothing and bedding. From http://www.globalaging.org/health/us/hypothermia.htm The most important step in treating hypothermia is to make and then keep a person warm and dry. ...

I don't have any good references for calorie expenditure, given that there are so many variables, so I will leave that to someone with a proper reference. In my personal experience in cold-weather, back country hiking and camping, the best time to wash is not at the end of a day's exertion when you are prone to getting chilled, but rather prior to starting ...

According to this article, Avijit Datta and Michael Tipton: Respiratory responses to cold water immersion: neural pathways, interactions, and clinical consequences awake and asleep, A fall in skin temperature elicits a powerful cardiorespiratory response, termed “cold shock,” comprising an initial gasp, hypertension, and hyperventilation despite a ...

Another good option are the gloves distance runners and cyclists use on cold days. These are what I wear when the temperature drops.

As EverythingRightPlace writes, you should focus on all your body parts. To survive the Polar Vortex you need: Winter boots. These should comprise of an outer boot and a removable inner boot. The inner boot should be well insulated from the outer boot. Trousers. You should wear long underpants, down-filled trousers and a wind stopper over that. Down ...

When we get cold vasoconstriction occurs. This prevents the blood at the extremities being subject to heat conduction away from the body. This is not an adaption, this is a reaction. The body emits heat all the time because the body working and but wants to remain at constant temperature. If the ambient temperature is such that we can lose this heat, we ...

Just to add to PPL's answer. The UK National Health Service has good practical advice on this also. It's available here. But to summarise some of the relevant points: Treatment for frostbite depends on how severe your symptoms are. You should always seek medical attention if you suspect you or someone else has frostbite. If symptoms are severe, ...

I do believe cold-shock is a real threat, but the reaction is a combination of physical and psychological reactions. As being dropped in near freezing water is a horrendous experience, even for the more hardy of us. The mind goes into full panic, only wanting to get up out of the water, often flailing and thrashing to do so. The physical effect just pours ...

You're talking about 2 extremes: very cheap sleeping-bag from supermarket and very expensive down sleeping bag for freezing temperatures. I've bought myself the synthetic sleeping bag, which was about 4 times cheaper than proffessional down one. However, I've bought the sleeping bag in proffessional outdoor store, made by known outdoor company. Find the ...

Gardening gloves are lightweight cotton or canvas. They are designed to be worn in the summer when it is hot. I take a pair canoeing to prevent paddle-blisters and for moving hot pots on a stove or logs in a fire. Long ago, women used to put on hand lotion at bedtime and then put thin cotton gloves on over that while the lotion sunk in. These are also not ...

Acclimatization isn't purely psychological; it is actually a physiologically different response based upon recent exposure and experience. Layering down over a period of time (days to weeks) could theoretically alter your biochemistry on a cellular level as you develop a different proportion of membrane proteins and salinity (see ...
