In a remarkable feat of innovation and endurance, four British former special forces soldiers have made mountaineering history by summiting Mount Everest using a pioneering acclimatisation technique involving xenon gas. The team, aiming to return to London within the week, set a new record for rapid ascent by leveraging the unique properties of xenon gas to adapt to the extreme altitude more quickly than traditional methods allow. Traditionally, climbers spend weeks acclimatising at various base camps to avoid altitude sickness—a process that can be both time-consuming and physically taxing. However, this British team, all veterans of elite military units, partnered with scientists to trial a novel approach: controlled exposure to xenon gas. This method is believed to stimulate the body’s natural production of erythropoietin (EPO), enhancing oxygen delivery and mimicking the effects of gradual acclimatisation. According to expedition leader Navin Singh Khadka, the results were extraordinary. 'We were able to cut down our acclimatisation period by more than half, allowing us to attempt the summit much sooner and with less risk of altitude-related illness,' he explained. The team’s success not only marks a significant milestone in mountaineering but could also revolutionise how future expeditions approach high-altitude climbs. The achievement has drawn attention from both the scientific and adventure communities, with experts suggesting that xenon gas acclimatisation could have broader applications for athletes and those working in extreme environments. As the four adventurers prepare to return to the UK, their record-breaking ascent stands as a testament to the power of innovation and the enduring spirit of exploration. Read the source »
