Climbing Mount Rainier, 14,411 feet (4,392 m) above sea level.. The effects of high altitude on humans are mostly the consequences of reduced partial pressure of oxygen in the atmosphere.
The climber's motto at high altitude is "climb high, sleep low", referring to the regimen of climbing higher to acclimatise but returning to lower elevation to sleep. In the Andes, the chewing of coca leaves has been traditionally used to treat altitude sickness symptoms. [45]
Once above approximately 3,000 metres (10,000 ft) – a pressure of 70 kilopascals (0.69 atm) – most climbers and high-altitude trekkers take the "climb-high, sleep-low" approach. For high-altitude climbers, a typical acclimatization regimen might be to stay a few days at a base camp , climb up to a higher camp (slowly), and then return to ...
Many deaths in high-altitude mountaineering have been caused by the effects of the death zone, either directly by the loss of vital functions or indirectly by poor decisions made under stress (e.g., not turning back in deteriorating conditions, or misreading the climbing route), or physical weakening leading to accidents (e.g., falls).
By the time of his and Sir Edmund Hillary's successful Everest climb, Norgay had been to the mountain six times and was a prolific high-altitude climber, earning numerous prestigious awards.
High-altitude climbing usually requires the use of portable oxygen apparatus when climbing Mount Everest or the other eight-thousanders, though some mountaineers—and alpine style climbers in particular—have deliberately ascended Everest without oxygen (e.g. starting with Reinhold Messner in 1978).
If you measure altitude above mean sea level, then the 29,032-foot (8,849-meter) Mount Everest, which straddles the border between Tibet and Nepal, is clearly the world’s highest.
High-altitude adaptation in humans is an instance of evolutionary modification in certain human populations, including those of Tibet in Asia, the Andes of the Americas, and Ethiopia in Africa, who have acquired the ability to survive at altitudes above 2,500 meters (8,200 ft). [1]
