Guests at Lanserhof, a 35-year-old clinic less than five miles outside of the Austrian city of Innsbruck that attracts architects, entrepreneurs, financiers, and other well-heeled clientele, often leave hungry. The health retreat is known for its fasting program: a minimum of seven days consuming 650 calories per day, on average. The benefits include a gut bacteria reboot, cell and liver regeneration, and reduced inflammation. A 2019 study demonstrated patients with chronic conditions improved after fasting between four and 21 days.
Medically supervised fasting has long been popular at clinics in Germany and Austria, where spending a week focusing only on your health is not unusual. But the desire to combine a wellness holiday with science-based treatments is on the rise beyond European borders.
Wellness tourism is set to grow from US$436 billion to over US$1 trillion by 2025, according to a report by the Global Wellness Institute. A growing movement called biohacking is accelerating the trend, driven by consumers seeking healthier as well as longer lives.
Melanie Gatt has practiced cellular, also called mitochondrial medicine, at Lanserhof since 2018. She’s seen an increase in clients seeking to reduce inflammation and optimise performance.
“There’s greater demand for improving the immune system, cellular regeneration and longevity,” she says. “Cellular repair is one of the most important issues for this. In the last week, I received three emails from regular clients all interested in longevity treatments.”
Biohacking Goes Mainstream
Entrepreneur and author Tim Ferriss has evangelised intermittent and longer-term fasting, dubbing it a “hack” to manage joint pain and other conditions. Ferriss and others, like Dutch wellness guru Wim Hof, have helped make biohacking mainstream.
Hof built a successful business and cult following globally with his two-pronged approach to combating wear and tear on the mind and body: mood-boosting ice baths and stress-reducing breath work requiring slow breathing.
Hundreds of certified Hof disciples around the world lead weekend and week-long retreats, including Chicago-based James Stewart. He started teaching Hof’s methods 10 years ago, and said one of the secrets to Hof’s success is his universal appeal to both men and women.
“The ice bath is a challenge,” Stewart says. “It’s a bit more robust and active, which makes it more appealing from a masculine point of view. And Wim Hof has made breathwork more palatable to people who might have been on the fence about it 10 years ago.”
A decade ago, Stewart says, he was the only person to brave the cold weather surrounding Lake Michigan for year-round dips. “Now, there are anywhere between 50 to 70 people who dip in winter. There’s something that grabs you physiologically; you’re getting that spike in epinephrine, norepinephrine, and you feel alive.”
Low-tech and high-tech treatments are being embraced by practitioners and consumers. In Los Angeles, Upgrade Labs bills itself as the first biohacking gym in the U.S., with an emphasis on specialized technology to assess cells and repair damage, along with a cryo chamber delivering cold immersion therapy with three-minute sessions in a sub-zero, temperature-controlled room or tank.
A Physical and Mental Reset
At Lanserhof’s clinic, a window stretching the length of an entire wall faces snow-covered mountains in a state-of-the-art setting that feels more like a futuristic command center than a medical office. Doctors provide detailed analysis from a wide range of diagnostics.
A 24-hour heart rate variability monitor reveals how activities like working, resting and eating impact energy levels and sleep quality. Intermittent hypoxic training uses an oxygen mask to simulate mountain climbing to measure how cells adapt to reduced oxygen availability, the study of which won the Nobel Prize in Medicine in 2019.
Stimulated by oxygen regulation, cells reject and replace damaged ones with healthy, new cells. An endurance test, called spiroergometry, tracks a patient’s individual fat burning zones, versus sugars. The information illustrates what intensity levels are necessary, or not, for an efficient and effective workout. Results dictate treatments like vitamin infusions, and sports scientists devise training plans to achieve peak performance, as well as recovery.
Historically, patients at Lanserhof and other fasting clinics tended to be older; seeking to improve a heart condition or rheumatic pain, but in the last 10 years, the average age of clientele has dropped from 55 to 47 years old.
Now, Gatt says, guests frequently visit as a physical and mental reset. “Some guests want to optimise their endurance, and some have reduced energy after experiencing infections and they want to understand what’s going on with their immune system and restore their energy levels.”
While it is possible to gather excessive amounts of information, extracting and understanding data related to specific health concerns, like burnout, can underline the impact of lifestyle habits.
Witnessing the impact of stress on the body and how quickly or slowly it recovers, is a great motivator to stop ignoring advice to meditate. For many of Lanserhof’s younger clients, Gatt says, the key to living healthier for longer may lie in obsessing less, rather than more about biohacking.
“We don’t suggest extremes, like doing something every day or eating one meal a day, which is not enough, because you start to lose the benefit and it becomes a stressor for the system,” Gatt says. “It’s easy to go too far. Part of longevity and regeneration comes from balance and knowing how to take a vacation.”

Chinese users of Xiaohongshu, or Little Red Book, welcome Americans fleeing a feared TikTok ban
They call themselves TikTok refugees—and the app they are fleeing to is a lot more Chinese than the video-sharing app whose U.S. fate now hangs in the balance.
After Supreme Court justices Friday seemed inclined to let stand a law that would shut down TikTok in the U.S., the Chinese social-media platform Xiaohongshu , translated in English as Little Red Book, has received a flood of American TikTok users. They are looking for a sanctuary or a way to protest the potentially imminent TikTok ban—never mind that they don’t speak Chinese.
Charlotte Silverstein, a 32-year-old publicist in Los Angeles, downloaded Xiaohongshu on Sunday night after seeing videos on TikTok about migrating to the app, which Americans dubbed “RedNote.” She described the move as a “last act of defiance” in her frustration about the potential TikTok ban.
“Everyone has been super welcoming and sweet,” said Silverstein, who has made three posts so far. “I love the sense of community that I’m seeing already.”
By Monday, TikTok refugees had pushed Xiaohongshu to the top of the free-app chart on Apple ’s App Store.
“I’m really nervous to be on this app, but I also find it to be really exciting and thrilling that we’re all doing this,” one new Xiaohongshu user said in a video clip on Sunday. “I’m sad that TikTok might actually go, but if this is where we’re gonna be hanging out, welcome to my page!” Within a day, the video had more than 3,000 comments and 6,000 likes. And the user had amassed 24,000 followers.
Neither Xiaohongshu nor TikTok responded to requests for comment.
The flow of refugees, while serving as a symbolic dissent against TikTok’s possible shutdown, doesn’t mean Xiaohongshu can easily serve as a replacement for Americans. TikTok says it has 170 million users in the U.S., and it has drawn many creators who take advantage of the app’s features to advertise and sell their products.
Most of the content on Xiaohongshu is in Chinese and the app doesn’t have a simple way to auto-translate the posts into English.
At a time of a strained U.S.-China relationship, some new Chinese-American friendships are budding on an app that until now has had few international users.
“I like that two countries are coming together,” said Sarah Grathwohl, a 32-year-old marketing manager in Seattle, who made a Xiaohongshu account on Sunday night. “We’re bonding over this experience.”
Granthwohl doesn’t speak Chinese, so she has been using Google Translate for help. She said she isn’t concerned about data privacy and would rather try a new Chinese app than shift her screentime to Instagram Reels.
Another opportunity for bonding was a photo of English practice questions from a Chinese textbook, with the caption, “American please.” American Xiaohongshu users helped answer the questions in the comments, receiving a “thank u Honey,” from the person who posted the questions.
By Monday evening, there have been more than 72,000 posts with the hashtag #tiktokrefugee on Xiaohongshu, racking up some 34 million views.
In an English-language post titled “Welcome TikTok refugees,” posted by a Shanghai-based Xiaohongshu user, an American user responded in Chinese with a cat photo and the words, “Thank you for your warm welcome. Everyone is so cute. My cat says thanks, too.” The user added, “I hope this is the correct translation.”
Some Chinese users are also using the livestreaming function to invite TikTok migrants to chat. One chat room hosted by a Chinese English tutor had more than 179,900 visits with several Americans exchanging cultural views with Chinese users.
ByteDance-owned TikTok isn’t available in China but has a Chinese sister app, Douyin. American users can’t download Douyin, though; unlike Xiaohongshu, it is only accessible from Chinese app stores.
On Xiaohongshu, Chinese users have been sharing tutorials and tips in English for American users on how to use the app. Meanwhile, on TikTok, video clips have also multiplied over the past two days teaching users the correct pronunciation of Xiaohongshu—shau-hong-SHOO—and its culture.
Xiaohongshu may be new to most Americans, but in China, it is one of the most-used social-media apps. Backed by investors like Chinese tech giants Tencent Holdings and Alibaba Group , Xiaohongshu is perhaps best described as a Chinese mix of Instagram and Reddit and its users increasingly treat it as a search engine for practical information.
Despite its Little Red Book name, Xiaohongshu has little in common with the compilation of Mao Zedong ’s political writings and speeches. In fact, the app aspires to be a guidebook about anything but politics.
Conceived as a shopping guide for affluent urbanites in 2013, Xiaohongshu has morphed into a one-stop shop for lifestyle and shopping recommendations. Every day, its more than 300 million users, who skew toward educated young women, create, share and search for posts about anything from makeup tutorials to career-development lessons, game strategies or camping skills.
Over the years, Xiaohongshu users have developed a punchy writing style, with posts accompanied by images and videos for an Instagram feel.
Chinese social-media platforms are required to watch political content closely. Xiaohongshu’s focus on lifestyle content, eschewing anything that might seem political, makes it less of a regulatory target than a site like Weibo , which in 2021 was fined at least $2.2 million by China’s cyberspace watchdog for disseminating “illegal information.”
“I don’t expect to read news or discussion of serious issues on Xiaohongshu,” said Lin Ying, a 26-year-old game designer in Beijing.
The American frenzy over a Chinese app is the reverse of a migration in recent years by Chinese social-media users seeking refuge from censorship on Western platforms , such as X, formerly known as Twitter, or, more recently, BlueSky.
Just like TikTok users who turn to the app for fun, Xiaohongshu users also seek entertainment through livestreams and short video clips as well as photos and text-posts on the platform.
Xiaohongshu had roughly 1.3 million U.S. mobile users in December, according to market-intelligence firm Sensor Tower, which estimates that U.S. downloads of the app in the week ending Sunday almost tripled compared with the week before.
Sensor Tower data indicates that Xiaohongshu became the top-ranked social-networking and overall free app on Apple’s App Store and the 8th top-ranked social app on the Google Play Store on Monday, “a feat it has never achieved before,” said Abe Yousef, senior insights analyst at Sensor Tower.
Run by Shanghai-based Xingin Information Technology, Xiaohongshu makes money primarily from advertising, according to a Xiaohongshu spokeswoman. The company was valued at $17 billion after its latest round of private-equity investment in the summer, according to research firm PitchBook Data.
Not everyone is singing kumbaya. Some Chinese Xiaohongshu users are worried about the language barrier. And some American TikTok users are concerned about data safety on the Chinese app.
But many are hoping to build bridges between the two countries.
“Y’all might think Americans are hateful because of how our politicians are, but I promise you not all of us are like that,” one American woman said on a Sunday video she posted on Xiaohongshu with Chinese subtitles.
She went on to show how to make cheese quesadillas using a waffle maker.
The video collected more than 11,000 likes and 3,000 comments within 24 hours. “It’s so kind of you to use Chinese subtitles,” read one popular comment posted by a user from Sichuan province.
Another Guangdong-based user commented with a bilingual “friendly reminder”: “On Chinese social-media platforms please do not mention sensitive topics such as politics, religion and drugs!!!”
