This was tested and “busted” on MythBusters: Turns out, just one alcoholic drink could make you feel warmer, but it actually lowers your core body temperature. How does alcohol employ this rule of opposites? Alcohol may make your skin feel warm, but this apparent heat wave is deceptive. A nip or two actually causes your blood vessels to ...

It is much better to avoid frostbite than to treat it. You can easily lose fingers and toes to frostbite. When you are camping in the winter, you cannot go into the lodge and warm up like you do snow skiing. You should really pay attention to frostbite. If it is much below freezing and you have numb fingers or toes, you should take some kind of action. If ...

Please don't drink alcohol to stay warm. It may make you feel slightly warmer temporarily, but it isn't actually helping you. According to my favourite volume on Wilderness Medicine (page 156), a small nip won't hurt you if you already have a cold-induced injury. However, it is strongly correlated with cold-induced injury, due to the cognitive impairment ...

I have found sleeping with my boots inside the bag is the ONLY way to go when it is really cold out. Moderately cold, sure you can tough out the re-thaw in the morning - but real cold... forget it. It is tough to get over the psychological barrier of putting boots in your bag - but it will make a difference. A few points to consider: During the day, sweat ...

Three things pee right before you go to sleep. I know it seems obvious, but people forget keep warm and sleep well. You can wake up just bursting to pee in the morning, or you can wake up kinda needing to pee at 3am and you can't get back to sleep. The sounder you sleep the more likely you can sleep through kinda needing to pee don't drink a LOT of liquid ...

Yes, the R-value will add of your different layers. If you wear layer A with R=5 and layer B with R=2.5, the overall insulation value will be R=7.5. To explain this a bit, we think of two layers or flat walls which interact only due to thermal conduction. This is just a model and in reality other effects will come in play. The Fourier Law for thermal ...

I believe that you should prepare with some additional first layers, bringing more socks is not a bad idea since you will be walking quite a bit (I assume). Otherwise I would focus some on bringing a little extra protection, in form of a scarf, fleece cap and a pair of gloves. Winter is a unforgiving time of year and you need to plan your clothing with ...

One option is to take them with you into the sleeping bag, just as anything else that needs to keep from freezing (like gas or batteries). I feel like my sleeping bag already takes enough beating as it is, so the boots stay outside. I just make sure they’re wide open, so that I can get them on my feet in the morning even if they’re frozen. Running a few ...

As stated above, the best way to treat frostbite is to avoid it all together. As for proper treatment, you should slowly warm the affected area, typically done through a warm water submersion. Frostbitten feet should not be thawed until you are ready to no longer walk, as you will more than likely lose the use of your feet. Additionally, in a situation ...

Cotton is the dominant bedding material choice worldwide for several reasons and as long as you aren't getting into the bag drenched and have adequate water control for your environment, I can't see the lining choice being a make or break factor in warmth. I can see it making the bag much more comfortable for casual use. Furthermore, for winter camping in ...

Some of us, when adventuring, go to far off remote places, in very cold or wet areas, and carry everything with us on our backs. But not everyone does that. Some people only car camp, in the summer, where bathrooms and showers are 200 feet away. For those sorts of camping situations, people's needs in a sleeping bag are essentially nothing more than ...

As said, prevention is better than cure. But, most importantly, don't attempt to thaw frostbitten areas if there's any chance of them re-freezing. This typically means don't try to treat it yourself in a back-country setting. ...And once you're in civilization, get a medical professional to handle it!

General tips to help you out: If your boots have felt liners, then remove the felt liners and keep them in your sleeping bag. It goes a long way to making things bearable in the morning, but I'd only recommend doing this if your liners are dry. Once you've set up camp, switch to hut slippers. This lets your boots/liners breath as moisture evaporates. Put ...

theJollySin is right. Your body adjusts to seasons by changing the viscosity of your blood. Thicker in winter to help stay warm, thinner in summer to help stay cool. Essentially, alcohol thins your blood, simulating what your body does to drop its temperature. Drink your whiskey, but sit close to the fire. Edit: The warming effect is not psychological. ...

According to wikipedia2 In calculating the R-value of a multi-layered installation, the R-values of the individual layers are added. I would imagine a slight diminishing return as the r-value is a laboratory measurement in ideal condition which is not quite the same as on the field (variable temperatures, moisture, air movement, etc.).

Should you just put them on and warm them up with your feet or is there a better alternative? In fact, I've found just putting them on and putting up with the cold for the first few minutes isn't that bad an option when you're used to it. It feels horrible putting them on, but after doing that and running around the tent a few times (which helps me wake ...

Very important: Do not exhale air into your gloves/boots or at your hands/feet while still exposed to cold conditions. It may warm them up for a few seconds but since your exhalation contains moisture, your extremities will get wet(ter) and even colder very quickly. Just a simple thing to keep in mind.
