At the summit, atmospheric pressure is about a third of that at sea level, so each breath delivers roughly a third of the oxygen. Above about 8,000 m, in what is called the '''death zone''', the body cannot acclimatise and deteriorates continuously; without supplementary oxygen, most people can survive there for hours, not days. |
| Winter winds on the summit routinely exceed 160 km/h as the jet stream touches the peak, and temperatures fall below −35 °C. The narrow calm before and after the summer monsoon produces the short climbing seasons in May and, less often, September. | Winter winds on the summit routinely exceed 160 km/h as the jet stream touches the peak, and temperatures fall below −35 °C.
