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, ...

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, ...

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 ...

No, seawater cannot be considered antiseptic. At minimum, Staphylococcus, which is the cause of many serious infections and deaths every year, and one agent of necrotizing fasciitis, is "able to survive: ... High levels of salt" and may even be spread by seawater. I recall reading (but am presently unable to cite) that parasites such as Cryptosporidium ...

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.

If it's a nice summer's day at lowest avalanche warning level in mid altitude you can still be hit by an avalanche and die. That being said in reference to the answer of @BenCrowell and the comments, it's just a matter of chances which are relatively low to get AMS (which are effecting your body in a serious matter) in regions up to 3000 m or even slightly ...

You are right, if you gain 3000+ meters within 6 hours, you are susceptible to AMS. A safe vertical height gain per day would be around 1000 meters. But since your question is more about what other symptoms to watch out for to identify AMS, here are a few that you can keep an eye on: Nausea. Dizziness. Loss of appetite(But at higher altitudes, this can be ...

"tight bandage/band" = Tourniquet. An emergency tourniquet is generally used as a last resort, especially in civilian applications, for all blood flow below the application of an emergency tourniquet is stopped, and can subsequently kill the tissue, leading to eventual loss of the limb below application. Never attempt to apply a tourniquet unless you are ...

Coming from an "enjoying nature" perspective, the equation becomes more simple in my estimation. If the trail can be expected to be reasonably well packed down, boots are perfect, traction cleats can be slipped onto boots if the hike is especially steep or slick. If the trail is expected to be deep powder, not hard pack snow.. snow shoes are easily the best ...

Postholing is more of an etiquette thing. On popular snowshoeing routes when people posthole thru a trail the make a thin deep canyon of snow. This makes it difficult for snowshoers to get nice flat sections to hike on. After the holes get covered by fresh snow, these holes become a mine field for people on snowshoes..

I'm a sailboat skipper with 25 years experience, so perhaps my tips could help a bit. Since the skipper is responsible for the safety and well-being of his/her crew, he or she also has a responsibility to avoid when possible situations which will make members of his crew seasick. For the crew: If you are susceptible to seasickness, consider starting to ...

I make my own laundry soap. I just found out that fels naptha soap found at walmart in the laundry isle is the best to use for the oils left on material items. Try it it works great and i save tons of money. Just grate the soap and mix with borax and washing powder. If you like you can also put in crystals. I use purex. 2 tsp in the wash cycle and WOW!

As your body gets used to the altitude, the symptoms go away. Therefore, if symptoms persist, Yes you should be worried. Altitude sickness can affect your lungs and brain. When this happens, symptoms include being confused, not being able to walk straight (ataxia), feeling faint, and having blue or gray lips or fingernails. When you breathe, you may hear a ...

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, ...

10,000 feet is not very high. Most likely the headache you were experiencing was due to some combination of sleep deprivation, caffeine withdrawal, and unaccustomed exertion and aerobic challenge. It would be unusual to experience any discomfort whatsoever at that altitude. Most people don't need any acclimatization for that altitude. I've hiked with a lot ...

Small addendum to the excellent answers already present: Never release a tourniquet unless you have received expert instruction on doing so. If the patient who received a tourniquet does not receive medical attention within a few hours, it is likely that the patient will loose the affected limb. Therefore, before applying a tourniquet, make sure that a ...

In addition to the suggestions above, regular use of walking or trekking poles are a great help in alleviating knee and hip problems.

There's a strap called Cho Pat that my dr. told me about -- it helps immensely.

Stop PAMPERING Your Feet if you Want Them TOUGHER! Not sure what you mean by "liner socks", but one of the worst footwear mistakes a hiker can make is wearing TWO pairs of socks. I would sincerely advise against two pairs of socks, if that is what was advised above. Most seasoned distance hikers and runners would tell you that, or ask yourself after doing a ...

Surgical spirit works every time. Rub it in using cotton wool for a month before you hit the trail. The best blister prevention is to walk, walk and walk.
