Mountain climbers need oxygen masks at high altitudes because the air becomes thinner and contains less oxygen, leading to hypoxia which can result in dizziness, shortness of breath, confusion, and even death. Oxygen masks help climbers supplement the oxygen they need to maintain proper breathing and prevent altitude sickness.
Climbers taking the northeast way from Silver Hut in Nepal, will need to cross the Barun glacier on their way to Mount Makalu. It's a dangerous journey for even the most experienced climbers.
The overwhelming majority of climbers that summit mount Everest use supplemental oxygen. A handful of climbers are able to do it without the use of supplemental oxygen. Reinhold Messner was the first person to summit mount Everest without supplemental oxygen in 1978. Ones ability to survive at altitude without supplemental oxygen depends on general fitness, acclimatization, and genetics. In order to get used to the altitude (acclimitize) most climbers make multiple carries between pre established camps on the mountain and spending days at altitude to adjust to the low oxygen levels in the air.
