at what elevation do humans need to use supplemental oxygen?

There is no specific point. It will also depend on the activity of the person, whether they are native to high altitudes like sherpas and whether they have acclimated by being at a high altitude for at least two weeks. Most people start noticing the effects of altitude somewhere between 4-6,000 ft above sea level. It gets progressively more difficult thereafter. If I remember correctly, Rheinhold Messner is, I think, the only person to have climbed Mt Everest without was painfully slow.


I think most people would say around 10,000 feet, though of course it depends on what the humans are doing.
