The idea that caffeinated drinks dehydrate you or "don't count" toward your body's water requirement is a myth. Laboratory studies have shown that caffeinated soda is just as hydrating as water, i.e., the diuretic effect of the caffeine is too small to measure.[Grandjean 2000] Even in the case of coffee, which has much higher concentrations of caffeine than ...

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, ...

General fitness is the only technique you can employ without going to higher altitudes. Acclimatization is the most common technique. Altitude sickness occurs at 2,400 m, so you go to a base camp (for example Cuzco if you're doing the Incan trail, or the South/North Base camps for Everest) and you let your body adjust to the altitude over a few days ...

There isn't necessarily a way to prepare your body for the altitude. You should however: Be in good condition overall, i.e. able to handle at sea level more than you are planning to do at altitude. Try to spend several days at a lower altitude (like 7000 feet) doing some aerobic activity before trying to go higher. Drink more water than usual. Take ...

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 ...

Aerobic conditioning will help a little with the altitude. You can practice walking / running on a treadmill at 15% incline. You can practice walking with a loaded backpack. Bonus points for doing it on an inclined treadmill.

Sounds like a myth to me. The only thing that could possibly come into play is the pressure inside your head. But in order to hold the pressure inside your head constant, you would have to plug your ears with something air-tight, not open your mouth, et cetera. I can’t see how a beanie hat or something like that could prevent the outside and inside pressures ...

Personally I do not know of any deterministic way judging acclimatization. Right now, the actions to be taken are more "Reactive". i.e, in case one feels the symptoms of AMS, then one can take a call of going down or camping at the current altitude to get acclimatized. As a thumb rule, if you climb higher, and sleep lower, your body should get adjusted to ...

The key to survival of any species in any part of the world is having a sustainable source of food. This applies to snakes as well. For snakes, humans are not food. For them, rats, lizards, scorpions, frogs etc act as food. When you specifically talk of snow covered areas, it is impossible for a snake to live. Or any cold blooded animal for that matter. I ...

If you'd lost, broken or simply didn't have any googles, I know in the days before effective UV protective eyewear, explorers would wear goggles with thin slits cut into them to reduce the amount of light entering the eye. In an emergency situation you could probably knock this up with a knife and some simple materials. How effective it would be, I don't ...

Snow blindness in simple terms is burning of the cornea and conjunctiva due to UV rays. At higher altitudes, the UV rays are more as less atmosphere is there to absorb these UV rays. Hence there is a higher chance of snow blindness at higher altitudes. Symptoms: Intense pain in the eyes. Huge amount of tears. Preventive Measures: Wear a protective ...

Other tidbits I've heard from local** guides: Wearing red increases your risk of being struck by lightning Burning egg shells will anger forest spirits and cause nightmares and illness The quickest way to heal a compound fracture is to wrap it with raw chicken Sticking tobacco in your socks will ward off leeches (this may have some validity). That's half ...

For me, as a thumb rule, when on high altitude treks, I do not go for any food which is digestion intensive. i.e, any food which required a lot of oxygen to get digested is not favorable. You can always have chocolate bars/energy bars at higher altitudes. Herbal tea is something that keeps you hydrated and gives you decent amount of caffeine at the same ...

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 ...

To deal with low oxygen environments you need more red blood cells. To get more red blood cells you have very few options. Blood doping Low pressure chamber treatments Actually going into higher altitudes on a regular basis (I recommend this one) Make sure your diet has enough iron to support the red blood cell production. However, iron by itself is ...

Find an area with a large stairway (football field bleachers work great), then power-walk/run up and down them while taking a break every few runs. Keep doing this until the trip, while increasing the number of "laps" when you think you're improving. When it starts becoming easier, pack up your backpack with your gear or simulate the weight with something ...

There is no documented scientific relationship between individual blood pressure and AMS. Furthermore, your guide appears to be completely mis-informed as to the mechanics of AMS. The most common symptom of AMS - a roaring headache - is caused by swelling of the brain as the body attempts to make up for reduced oxygen in the blood by pumping harder and ...

Energy bars (and protein bars, power bars, etc) are typically dehydrated in order to improve shelf life as well as increase the ratio of calories/nutrients to weight. Their longevity and energy per ounce make them ideal foods for hikers and mountaineers, but your body will require some additional water to metabolize the nutrients and ingredients. However, ...

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 ...

Three thoughts: If the snow is thigh-high, then you should be either using touring skis or snowshoes to "float" over the snow. You'll expend way less energy. Seriously, I can cover probably 10x-50x the distance (or more) with alpine touring gear or snowshoes in the same amount of time as someone without, and that's regardless of the angle of slope. ...

In my opinion the best would be to have a couple of more advanced friends who are able to teach or even know guides or groups and go with them for fun and to learn. Unfortunately I am not having this opportunity (yet?). How that, when you are already a member of the DAV? It is first and foremost an club of mountain enthusiasts, not a provider of ...

British mountaineer Andy Kirkpatrick has quite a bit of useful information regarding how to look after your feet at altitude and in cold conditions on his website at http://www.andy-kirkpatrick.com/articles/view/how_to_avoid_frostbitten_feet. The only recommendation on footwear size he gives with respect to high altitude, is for Neoprene socks. He ...

In terms of the average hike that you talk about, with not reaching your intended campsite, there's really no difference in bivouacking and just camping without a tent. So you'd basically look for similar conditions that you'd normally camp in. Find a place out of the wind, preferably with a cover like trees. Make sure you're on high ground and not in ...

An unhurdled slip-and-drop would be fatal without a doubt. If this is the case, then maybe you need a belay. However, if the snow is sufficiently deep and soft that you're sinking up to your knees, why is it the case that slipping and being unable to self-arrest is so dangerous? In these conditions, typically you can't even intentionally get going fast ...

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 ...

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 ...

I think @Greg's answer is excellent, but I'd add the following. It's true that there's a delay before altitude sickness sets in - this is what makes going up to a 4000 meter peak on your second day possible. However, should conditions on the top be bad, and you end up staying up there, you are at some risk of altitude sickness. For example, if you twist your ...
