Climbing Everest Without Oxygen

Everest is extremely difficult without supplemental oxygen.
At high altitudes, oxygen is scarce, requiring 15 breaths per step.
Ed Viesturs, a notable climber, documented the challenges.
He reached the summit of all 14 8,000-meter peaks without oxygen.
He described the struggle of altitude sickness and difficulty breathing.
Lack of oxygen is a life-threatening condition at high altitudes.
Hypoxia (lack of oxygen) causes breathing to quicken.
Physical tasks become noticeably harder.
Appetite drops, making it hard to stay nourished.
Dehydration is also a frequent concern.
Blood thickens, leading to a higher risk of frostbite.
Decision-making, sleep, and judgment are impaired.
Hallucinations and risky behavior are possible symptoms.
Other climbers have even died from this experience.
Only a few climbers attempt this challenge.

Climbing without Oxygen - a Fine Line

Very few (3 out of 100) climbers attempt to summit without bottled oxygen.
Achieving the peak is an extraordinarily physically taxing endeavor.
The experience is dangerous.
Several have died in the attempt.
Significant risks are associated, including permanent brain injury or death.
One climber, Reinhold Messner, and another, Peter Habeler, were early successful summiters without oxygen, in 1978.
Scientists quantify the experience as more like climbing a lower mountain.
Specific climbers chose the challenge to assert their skill and willingness to face mortality in the process..
One climber used a tent to simulate the thin-air conditions at altitude.
