Hot soup mostly, it does depend on the individual diets of the climbers, not everybody eats the same thing, but most carry hot soup with them. Despite the massive amounts of energy needed to summit Everest, the truth is most climbers don't eat much on summit day, and that's simply because they don't have an appetite due to the high elevation. Many climbers ...

TLDR: Yes, it can happen at that altitude, but the odds are extremely low. Long answer High-altitude cerebral edema has happened at lower than 10,000 ft. The condition is seldom seen below 3,000 metres (9,800 ft),2 but in some rare cases it has developed as low as 2,500 metres (8,200 ft). Source To give an idea of how rare those rare cases are, ...

I personally had a similar sort of a question when I first went through similar kind of stats about these mountains. Getting introduced with these stats is different than totally understanding the mountain and the pandora box it opens. For getting acquainted with the reasons for so many failed attempts, one needs to read tactical data and expedition reports. ...

In 1996, they seemed to enjoy chocolate bars and candies. From some of the accounts of the infamous 1996 season related by the 2015 movie, apart for the classic soup, tea and fluids, we can consider "junk food" on summit day: Matt Dickinson (the other side of Everest) eats Muesli and pistachio nuts. Lou Kasischke (After the wind) was very fond of M&...

I only see an advantage if your boots are wet: Then I would advise to remove the wet shoes and socks. Maybe you are in the lucky position to have some dry spare socks in your backpack. If not you may have a bivi sack to heat up your extremities. Otherwise you can at least put your feet in your backpack. This would help immensely. If the boots are dry, I ...

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 ...

Apart from the practical advantages mentioned in practicality of beards, there's also some aspects that are special to remote and/or high altitude trekking: Melting snow to obtain water costs a lot of fuel (and time) which makes water quite a valuable good. You don't want to spend 10% or more of your expensively molten water just to pollute it with shaving ...

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, ...

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. ...

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 ...

Lemon juice and tinned fruit From Tenzing's autobiography Man of Everest We started pitching the highest camp that has ever been made. And it took us almost until it was dark. First we chopped away at the ice to try and make our sleeping-place a little more level. Then we struggled with frozen ropes and canvas, and tied the ropes around the ...

Ear popping is due to the difference in the pressure between the outer and the middle ear. Popping of ear occurs at high altitude to allow for the two pressures to equalize. Now, there's no correlation between ear popping and altitude sickness in the first place. So, in case you are worried about AMS due to the non-popping of ears, it wont happen. Second, ...

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 ...

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 ...

It has to go down to all the High-Altitude diets, and not just specific to Mt. Everest. Anywhere above 23,000 feet / 7,000 meters most of the mountaineers lose their appetite to a considerable level. So, at that altitude losing weight is a common observation. Thats where the fats come in picture. Body starts consuming these bodily fats and worst case muscles ...

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.

Altitude acclimatization is not just a single change in your body but a long list of different things that are going on. There is a nice chart on p. 326 of House and Johnston, Training for the New Alpinism, which gives a list of the following adaptations (they label #6 as two items): increased ventilation rate increased heart rate and blood pressure blood ...

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 ...

Anecdotally, the only three factors which may cause you problems are: supplies running out losing fitness boredom And these are really only an issue if you are stuck for extended periods of time. Your solutions are: exercises you can do in your tent, or just outside - stretches, press-ups, sit-ups, basic cardio - will help you maintain a level of fitness ...

I wouldn't call it normal, but it does happen and if the bubble is large enough it will effect your accuracy. In that case you may want to purchase a new one or if possible send it back to the manufacturer. From Silva's FAQ page We intend that our compasses are free of bubbles; however, if a small bubble forms in the liquid-filled capsule, it has no ...

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 although it can easily take a week. However, acclimatizing has its limits, somewhere between ...

The other answers already gave lots of information about altitude adaption, so I will focus on one certain point: AMS (acute mountain sickness) evolves when staying at high altitudes. It is a pathologic disease with potential severe consequences. This should not be mixed up with the immediate influences of high altitude on the body like decrease of physical ...

The standard expedition stove for extreme conditions would be an MSR XGK. You will likely want to bring a pair of them, along with a repair kit, on the assumption that due to the cold or poor quality fuel you'll break a pump or need to make other repairs. Now, you may be thinking "what are all those people doing with canister stoves on Everest/Aconagua/...

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 insurance ...

I'll try and be brief but specific towards answering your question: What exactly happens to your body at high altitude? Disclaimer: A lot of data is from Wiki Pages and definitions from Human Anatomy and Physiology Books. Breathlessness and Hyperventilation: Does it start with one panting for breathe? Yes it does! We all know that Atmospheric pressure ...
