what is the main cause of death on mount everest
List of people who died climbing Mount Everest The upper reaches of the mountain are in the death zone. The death zone is a mountaineering term for altitudes above a certain point – around 8,000 m (26,000 ft), or less than 356 millibars (5.16 psi) of atmospheric pressure – where the oxygen level is not sufficient to sustain human life.[2] Many deaths in high-altitude mountaineering have been caused by the effects of the death zone, either directly (loss of vital functions) or indirectly (unwise decisions made under stress or physical weakening leading to accidents). In the death zone, the human body cannot acclimatize, as it uses oxygen faster than it can be replenished. An extended stay in the zone without supplementary oxygen will result in deterioration of bodily functions, loss of consciousness and, ultimately, death.[3][4][5]
Dolores O'Riordan The cause of death was not immediately made public;[55] police said it was not being treated as suspicious.[56] The coroner's office said the results of its inquiry would not be released until April at the earliest.[57]
