Do people still climb Everest without oxygen?

Yes, there are still people who choose to climb Mount Everest without the aid of supplemental oxygen. These brave individuals are known as “purists” in the climbing community, as they strive to experience the mountain in its most raw and challenging form. While the use of oxygen can help climbers combat the thin air and low oxygen levels at high altitudes, climbing without it presents an even greater physical and mental challenge.


1. Why do some climbers choose to climb Everest without oxygen?

Climbing Everest without supplemental oxygen is a personal choice for many climbers who see it as a way to truly push their limits and test their physical and mental strength. They believe that using oxygen bottles alters the purity of the climbing experience and prefer to rely solely on their own abilities.

2. How common is it for climbers to attempt Everest without oxygen?

While the majority of climbers choose to use supplemental oxygen during their Everest expeditions, there is still a small but determined group of purists who attempt the climb without it. This group accounts for about 5-10% of all climbers who make the summit attempt each year.

3. What are the challenges of climbing Everest without oxygen?

The main challenge of climbing Everest without oxygen is the extreme altitude and lack of oxygen. As climbers ascend higher and higher, the air becomes significantly thinner, making it difficult to breathe and perform physical tasks. This can lead to symptoms of altitude sickness, including fatigue, dizziness, and headaches. Climbers without oxygen need to acclimatize more slowly and carefully, and they may have to turn back if their bodies cannot adapt to the conditions.

4. How do climbers prepare for climbing Everest without oxygen?

Climbers who plan to climb Everest without oxygen need to undergo intense physical training and altitude conditioning. They must build up their aerobic capacity and strengthen their bodies to endure the harsh conditions on the mountain. This includes regular cardiovascular exercise, strength training, and simulated altitude training.

5. Are there any advantages to climbing Everest without oxygen?

One advantage of climbing Everest without oxygen is the weight reduction, as climbers do not have to carry heavy oxygen tanks. This can make the ascent slightly easier in terms of physical strain. Additionally, purist climbers argue that the experience of summiting Everest without artificial assistance is more authentic and rewarding.

6. What are the risks of climbing Everest without oxygen?

Climbing Everest without supplemental oxygen significantly increases the risks associated with the expedition. The lack of oxygen at extreme altitudes can lead to serious health issues, such as high altitude pulmonary edema (HAPE) and high altitude cerebral edema (HACE). These conditions can be life-threatening and require immediate descent to lower altitudes for treatment.

7. How does climbing Everest without oxygen affect success rates?

The success rates for climbers attempting Everest without oxygen are generally lower compared to those who use supplemental oxygen. Climbing without oxygen requires a higher level of physical fitness and endurance, as well as exceptional acclimatization skills. As a result, the percentage of climbers who successfully reach the summit without oxygen is significantly lower.

8. Are there any famous climbers who have summited Everest without oxygen?

Yes, there have been several renowned climbers who have successfully summited Everest without oxygen. One notable example is Reinhold Messner, an Italian mountaineer who achieved the feat in 1978 alongside Peter Habeler. Messner is widely regarded as one of the greatest climbers in history.

9. How do climbers deal with the extreme weather conditions on Everest without oxygen?

Climbers without oxygen must rely on their physical endurance and mental resilience to endure the extreme weather conditions on Everest. They need to carefully plan their ascent during the optimum weather window and be prepared to retreat if the conditions become too dangerous. Proper gear, including warm clothing and high-quality mountaineering equipment, is essential for survival.

10. How does climbing Everest without oxygen impact the body?

Climbing Everest without oxygen puts a tremendous strain on the body. The lack of oxygen affects the respiratory system, making breathing difficult and causing fatigue. Exposure to extreme cold temperatures can also lead to frostbite and other cold-related injuries. Climbers must carefully monitor their physical and mental states to avoid serious health complications.

11. How long does it take to climb Everest without oxygen?

The duration of a climb without oxygen can vary depending on factors such as weather conditions, physical fitness, and acclimatization. On average, it takes climbers around 2-3 weeks to complete the ascent and descent. However, this timeline can be significantly longer for those attempting the climb without the aid of supplemental oxygen.

12. Are there any support systems in place for climbers attempting Everest without oxygen?

Expedition organizers and support teams are available on Everest to assist climbers, whether they choose to climb with or without oxygen. These support systems provide essential logistics, such as food, equipment, and medical assistance. However, climbers attempting the climb without oxygen generally rely more on their personal skills and experience due to the added challenges they face.

In conclusion, while climbing Mount Everest without oxygen presents numerous challenges, both physical and mental, there are still individuals who choose to undertake this incredible feat. These climbers believe in pushing their limits, seeking a more authentic experience, and proving their resilience on the world’s highest peak. However, it is important to note that climbing without oxygen significantly increases the risks involved and requires meticulous preparation, training, and understanding of the dangers associated with such an endeavor.
