I've never succeed in "hardening" my feet against blisters, even when I was barefoot growing up. However these things have worked for me Vaseline or (preferably) diaper rash ointment before putting on socks Injinji toe socks (If I double socks, these are always my base layer) These worked on long hikes even when my feet got wet, and even in poorly ...

If you want a natural solution, try lemon eucalyptus oil. Considering that B1 does not deter mosquitos, any dose you like will be comparable to 75mg (zero effect). However, if we wish to assume it works, you'll want the patch. Eating B1 won't help much. Since B1 is principally excreted in your urine, eating a lot of it would only really help if you ...

Yes it is possible to sunburn through clothing. Clothing does block some of the Ultraviloet radiation but not 100%. A lot of outdoor recreation clothing is now marketed with treatments that gives additional UV protection.

I traveled in Cambodia with a doctor who has decades of experience in tropical medicine. On his recommendation, our group: Wore long sleeves and pants at all times, despite the heat. We chose the the lightest materials we could find, but kept our skin covered. Soaked those clothes in permetherin before going. After it dries, it continues to repel or kill ...

It would say it varies to a high degree since the source of the meat and the cut of the meat will be the primary factors in determining how many bacteria (and which type) will be on the surface of the meat. I wouldn't want to trust hamburger or mass market ground meat for even a few hours not refrigerated - so any meats that are mechanically tenderized or ...

There are three criteria to be balanced in my thinking on the situation of when and if to activate a call for help to a rescue service: Do you have the skills and training to extract yourself safely from the current situation? Equally important is your assessment of what other means of communications are likely to be available in the timeframe your current ...

It depends on precisely how big the kit is. A couple other answers have covered bigger packs, so I'll mention what could be in a much thinner pack. If it needs to be flat and relatively small: Bandages. Alcohol wipes. Gauze pads. A flat pad of athletic tape*. One or a couple small packs of Benadryl Antibiotic ointment (the small, flat packs of stuff ...

In the core alps (Liechtenstein, Switzerland, and Austria), you can drink water almost everywhere directly without filtering. There are only two exceptions: If there is a thing or something like this that forbids drinking it, or if you can see an obvious reason not to drink it, like for example a strange smell or abnormal color. In the other countries in ...

The short answer is, it varies. The three factors that most influence the UV transmission factor of clothing are kind of obvious: Material: Some materials are better at absorbing UV than others; for example, the paper cited below suggests that polyester absorbs more UV light (particularly UVB) than cotton. Weave: The thicker and more tightly woven a piece ...

Around sunrise and sunset, the sun is much less intense. You would get around 5 times less intensity in the first or last hour of sunlight than in the middle of the day. Here is a graph of this effect (It's from a paper, though the paper itself is behind a paywall), and another one which also shows the effect of latitude. Therefore, while you can’t say ...

Are you going to be hiking that high, or in a car for a small bit? Going to 15,000 feet without ever having broken 10,000 feet sounds a bit haphazard, especially if you're unsure of the dangers/how to deal with them. There are several things you can do to help yourself out before your trip. First, acclimate. Don't just run up to 15,000 feet. Try to spend ...

Headaches are common symptoms of altitude sickness. It's a sign your brain is not getting enough oxygen. As with lots of mountain issues it's down to judgement. If the headache is impairing your ability to perform at altitude, then yes, it's dangerous. If you can't concentrate on what your doing then your a danger to yourself and others. Bear in mind, ...

Seawater is not itself sterile, in fact, it has all kinds of organisms. Salt in a wound is likely to hurt, and saltwater won't be a particularly effective antiseptic. With wound cleaning, it's always a question of trade-offs. It might be better to use less-than-sterile water to clean an extremely dirty wound if infection is otherwise inevitable. However, ...

The best thing you can do is acclimatize. This means you should adjust your body gradually to the height. This can be done, for example, by increasing the height you're staying at from day to day. Another very important fact that is widely used by mountaineers is that you should always sleeps some meters below the highest point of the day. So for example, ...

Normal detergent should be able to break down the poisonous oils in question, it shouldn't require any specialist stuff to remove them. Just be sure of a few things: Wash infected clothes separate from "clean" (i.e. unaffected) ones to eliminate any possible risk of spreading Make especially sure you don't overload the machine - leave plenty of room so the ...

I appreciate the preference to use natural protection, however, I think it is important to point out that using insect repellent should not be the only method of defence against malaria that you employ. Insect repellent is not 100% effective (*) and does not directly prevent malaria - the mosquito acts as the host to transmit the Plasmodium parasite, which ...

This is really up to you, but I think if postholing is enough of a issue it would be good to wear snowshoes. If nothing else, it just makes things easier. One problem of postholing can be sometimes difficulty in getting out. You're not likely to actually get hurt, because "falling" onto the snow isn't a problem when it's deep and soft enough for your foot ...

Talked to my doc today during a visit for something else. It's Iliotibial Band Syndrome. The ligament that runs along the outside of the knee becomes irritated and inflamed. It's often caused by over-pronation and poor gait which is exacerbated on the weight bearing leg (not the landing leg) when going downhill. Once injured, the only good solution is ...

It takes more than 4-5 days to have problems from a limited diet, as long as you get enough of short-term things like salt (which is not normally a problem). Even so, I usually take some Flintstone chewables and dehydrated meals along to be healthy.

First, Freeze-dried Vegetables. Unfortunately, the texture isn't quite right, but it works. Secondly, if you want actual FRESH veggies, then I'd recommend sprouts grown in your pack Thirdly, if you will be resupplied during the trip, arrange a few fruits/veggies from the local store. I know through-hikers will go into town on resupply-day and eat in a ...

As found here: "With every 1000 m in altitude, UV levels increase by approximately 10 per cent." Percentages are tricky to work with, so here is a worked-out example. Suppose you start out at sea level (0m), and you climb all the way up to Mt. Everest's summit (8848m). Suppose also that at sealevel, you normally need to apply sun block factor 15. Then, ...

There are two types of water-based concerns while doing strenuous activity in the desert: dehydration and hyponatremia. Dehydration occurs when your body is not getting enough water, and is the most common. Symptoms include irritability, headache, lack of energy, bright yellow/orange and infrequent urine. You lose water while you sweat, but in hot climates ...

The wikipedia article on sun protective clothing is very informative. A summary of the relevant parts: Apart from clothing specifically marketed as protecting against the sun most clothing will not block all sun to fully protect you against sunburn depending on circumstances. Some general rules of thumb: Darker clothes provide more protection than ...

My mother suffers from every form of travel sickness, and the only solutions she has found that help to ameliorate the symptoms (if not actually remove them entirely) are: Drugs: specifically Stugeron Bracelets: I am a bit skeptical of these, as is Skeptics.SE, but they seem to work for her. Example here If I feel at all queasy in really heavy seas (ie ...

As far as I know you should be able to survive for quite a long time. I often hear about ocean racers who have just freeze-dried foods to eat and they live on that for more then 2-3 months at a time. There are no side effects, they are in fact very healthy. So I see no issues apart from a very dull taste that you can't live on this indefinitely. As far as ...

For wounds with heavy bleeding or that are deep, the standard practice is to: Apply direct pressure to the wound. Elevate the injury to decrease blood flow. In short, if the flow of blood is high enough that it won't clot then you want to impede the output by whatever means possible. As mentioned elsewhere, tourniquets are a last resort, where the lose ...

My understanding is that anything above 4000 metres you can drink due to there being a low chance that anything living will affect the water i.e. animal faeces and bacteria etc.

Bring a wilderness first aid guide! Even if you have training, it could save your life if you're the one injured and someone else is trying to take care of you with your own kit. Here is a list of things I would have in pretty much any hiking first aid kit. There are other items worth considering for kits, but I consider these to be the minimum. Wound Care ...

Okay just broke out my kit. Here's what we carry. This may seem like a long list, but it's small. It fits in a ziploc bag (almost). Also, please note that you should pack for your skill set and first aid training. If you don't know how to use a splint, it's wasted and will tempt you to do things you shouldn't. Same goes for sutures. Know how benedryl ...

Either option is acceptable, particularly since you aren't going very high. There are rare instances where people get Acute Mountain Sickness (AMS) or worse even at relatively low altitudes, and these are more common when there is no acclimatization. However, it is very rare for such problems to suddenly arise and not be fixable (through rapid descent). Each ...
