What happens to your body at the top of Mount Everest - Andrew Lovering

Fun fact: Staying at high altitudes before a competition is a form of legal doping in sports. As the athlete will have more red blood cells, they will be capable of more performance.

No, that’s Andeans. Sherpas naturally have less hemoglobin because we’ve lived at high altitudes for about 30,000 years whereas Andeans have only had 10,000 years to adapt.

Being a casual Trekker, I must say Wim Hoff's breathing technique, also mentioned in the video, has been really helpful. We must let our body acclimatize before we make the ascend and to do that, we must focus on our breathing as it becomes prominent factor for acclimatization. Hence, this video is a must for those who wants to ascend mountains here in Nepal. P.s. I have reached the height of 5500m finishing 2 complete trekking circuits in a month.

Also, I have lived my whole life above 2500 meters of altitude, I would live to know how this had affected my body. :) blessings from Ecuador 🇪🇨

it is pretty amazing how differently bodies can react to stimuli, too. Several times I've seen people faint in cable cars when the altitude was not even 2000m, whereas I've gone from 2000m to 4000m and back in a one day hike, at a pretty strong pace, and I felt almost nothing at all until I was close to the top (I was probably at a bit climatized to the 2000m altitude to being with). Or, for example, I cycled the Pamir Highway with a friend and at 4000m we were going fast with our bikes like it was nothing, feeling no differently from how you'd feel at sea level (we had also had some days to climatize).

[@catdogmousecheese]

Actually, climbing Everest isn't as impressive today as it was 50 years ago. There are actually entire travel agencies that specialize in helping people climb Everest; they'll plan your route, tell you exactly what supplies you'll need, and get you in contact with a local guide. In fact, a large percentage of Nepal's national GDP is tourism from people wanting to climb or at least see Everest.

It would have been interesting to have included an explanation of the "death zone." This video talks about 1500, 2500, 4000m altitude, but Everest is nearly 9000m tall, making it very different from getting altitude sickness at 2500m.

[@mr.fanstastic9010]

It cannot be said enough times: No one reaches the summit of Everest without the Sherpas. NO ONE past, present or future, including the greatest Western mountaineers, so show some humility. If you did not carry all the supplies to ABC, if you did not fix all the rope and the ladders yourself, you did not solo independently. FULL STOP!

[@jonathanmather6897]

Not true at all. Messner and Habeler did it without oxygen and without Sherpa guidance in 1975, and I guarantee you it would be done more often if it were legal, but the Nepalese government has long since regulated Everest ascents for both monetary, but also environmental reasons. You have to climb with sherpas now as a tourist, but this isn’t because it’s an impossible feat without them.

[@Reckoning2943]

Person with South American/Andean roots: we do indeed not get sick so easily in altitudes. I’ve travelled and walked numerous times in altitudes of 5000m and it’s kind of a running gag among us to see all the tourists being sick outside of their busses along the way. It goes even as far as having great lung volume, even without training for it, needing very little water to drink and having very thick skin whose pores won’t open up easily. We’re literally built to live in arid regions of very high altitudes, but, even we do know our limits. Some of those mountaineers think they’re gods, they’re too confident, and that’s how they end up struggling.

[@recoveringsoul755]

I hiked the highest mountain in the lower 48, just under 14,500 feet, no idea what that is in meters. We started at around 4,000 feet, first few days gained 3,000 feet each day, then some ups and downs. Coming from sea level and doing the whole thing in a week doesn't really give you time to acclimate. Need a few days at each elevation. For some reason, women are less likely to get altitude sickness, despite smaller lungs and hearts. When COVID started it was affecting men more, and they were saying it was similar to altitude sickness. Also heard certain blood types of people were able to handle High elevations better for some reason
