Xenon Helps Four British Men Scale Mount Everest. Why Has It Caused Controversy?
The group, all former British special forces members, became the first climbers to use xenon gas to scale the world's highest mountain.
Climbing Mount Everest has always been seen as a test of endurance, patience and physical strength. But four British climbers recently made headlines for achieving the feat in just a few days using a gas that is not commonly associated with mountaineering.
The group, all former British special forces members, became the first climbers to use xenon gas to scale the world's highest mountain. The climbers included Alastair Carns, a parliament member and minister for veterans at the Defense Ministry along with Garth Miller, Anthony Stazicker and Kev Godlington. Their expedition, organised by Austria-based Furtenbach Adventures, reached the 8,848-metre summit in less than five days after leaving London.
While their achievement is notable, their use of xenon gas has stirred debate in the mountaineering community and triggered an official investigation in Nepal.
What Is Xenon Gas?
Xenon is a colourless and odourless gas that is over four and a half times heavier than air. It is found in tiny amounts in the Earth's atmosphere and is known for its use in medicine, especially as an anaesthetic.
The gas is also used in many other areas. According to CK Supply, it's found in projector and cinema lamps, camera flashes, car headlights, CT scans, satellites, deep space missions, nuclear energy and metallurgy.
Lukas Furtenbach, head of Furtenbach Adventures, told Reuters, 'Xenon improves acclimatisation and protects the body from altitude sickness and the effects from the hypoxic environment."
How Did The Climbers Use It?
The four British climbers inhaled xenon gas in Germany before beginning their expedition. They also trained at home using special tents that mimic high-altitude conditions. This pre-acclimatisation helped them avoid spending weeks on Everest adjusting to the low oxygen levels which is typically required.
During their actual climb, they still used supplemental oxygen like most mountaineers.
Furtenbach said the shorter expedition also helped reduce waste on the mountain. 'Less garbage, less resources, less human waste in this sensitive environment," he told Reuters.
Why Is The Use of Xenon Drawing Attention?
Nepal has started an investigation into the use of xenon gas by four British army veterans who recently climbed Mount Everest, according to The Kathmandu Post.
In a statement, Nepal's Department of Tourism said it had taken note of the media reports about the climbers' achievement. 'We are currently engaging with the expedition team leaders, members, and the associated agencies to gather detailed information and conduct a thorough study and analysis of this matter," it said.
What Are Experts Saying?
Peter Hackett, a mountaineering physician, told The Washington Post that xenon can temporarily increase erythropoietin (EPO), a hormone that stimulates red blood cell production. 'It did not increase red blood cells and it did not increase their exercise performance" in a study conducted on athletes, he said.
Dr Andrew Peacock, an altitude medicine expert at the University of Glasgow, also shared a similar view with BBC, saying, 'Increase in erythropoietin does nothing on its own. The question in this case is, does it really stimulate production of red blood cells in such a short period?"
The International Climbing and Mountaineering Federation (UIAA) also weighed in. 'According to current literature, there is no evidence that breathing in xenon improves performance in the mountains, and inappropriate use can be dangerous. Although a single inhalation of xenon can measurably increase the release of erythropoietin, this increase is not sustained over four weeks' use, nor is it associated with any changes in red blood cells. According to the literature, the effects on performance are unclear and probably non-existent," it said as quoted by BBC.
Ethical Concerns
The use of xenon isn't only raising health concerns, it has also started a debate about ethics and fairness in mountaineering. According to Reuters, American climber Adrian Ballinger called the method a 'stunt" and said, 'It's never seemed like the type of experience we want to provide." He added that using xenon makes the climb feel more like 'mountain tourism" than real mountaineering.
Ballinger also told the Washington Post, 'It is a banned substance by all professional sporting organisations, and even though [mountain climbing] is not managed by a sporting organisation, it's always been a goal of climbers to follow best practices of not doping. All that combined makes it feel, I guess, pretty icky. People should be able to climb how they want to, but it isn't mountain climbing; it's mountain tourism."
Damber Parajuli, president of the Expedition Operators Association of Nepal, told the BBC that shortcuts like this could damage the credibility of summit certificates and hurt the trekking industry.

Health department seeks probe into ‘unethical' clinical trials at HCG
BENGALURU: The Health and Family Welfare Department has written to the Drug Controller General of India (DCGI), seeking an investigation into alleged unethical clinical trials at Bengaluru-based HCG Hospital, a well-known cancer care hospital chain. The department acted after Justice P Krishna Bhat, former chairperson of the Institutional Ethics Committee (IEC) at HCG, raised serious concerns and resigned earlier this year. His resignation followed complaints about how clinical trials were being handled, especially patient safety, ethical violations and conflicts of interest. In a letter dated June 30, the health commissioner noted that the allegations raised questions about compliance with rules and integrity of clinical research. 'These lapses, if proven, will undermine the strict ethical principles laid down by DGCI, ICMR, DHR, and bodies like WHO,' the commissioner said. Justice Bhat had written on March 5 outlining several concerns. One of the main issues was a conflict of interest — Dr Sathish, director of clinical trials at HCG, was also acting as principal investigator (PI) or co-PI in many of the clinical trials he was supposed to oversee. This, according to medical research rules, is not allowed. ICMR states members of an ethics committee should not act as investigators in the same studies, as it affects independent judgement and patient safety.

Britain launches 10-year plan to save health service in crisis
London: British Prime Minister Keir Starmer on Thursday will launch a 10-year strategy to save a National Health Service he said was in crisis, as he aims to alleviate the burden on overstrained hospitals and provide care closer to people's homes. The state-run, publicly funded NHS has struggled to recover from the impact of COVID-19, endured annual winter crises and several waves of industrial action, and currently reports long backlogs for elective procedures. Starmer has previously warned that the NHS must "reform or die" and pledged an overhaul of the system that would manage the rising costs of looking after an aging population without hiking taxes. In a statement, Starmer said that his Labour Party had inherited a health system in crisis when it came to office one year ago, but that the plan would "fundamentally rewire and future-proof" the service. The plan included establishing new health centres bringing a broader range of services under one roof. The government said that would free hospitals from "perpetual firefighting" and bring down waiting lists. After a rocky first year in government marked by unpopular spending cuts - and in some cases followed by costly policy reversals - health care is one area where Starmer's party can claim some success. It has delivered 4 million extra appointments - double its first year target - and cut waiting lists to a two-year low. Starmer said the NHS could not be fixed overnight, but that his government was "already turning the tide on years of decline". Nevertheless, the government remains in an impasse with the pharmaceutical sector on drug pricing. It also faces possible fresh industrial action from healthcare staff and is yet to publish a promised strategy to fast-track development of the country's life sciences sector.
