The concept of longevity—extending both lifespan and quality of life through lifestyle practices—has never been more prevalent. According to health assessment specialist Dr. Sabine Donnai, the term gained significant traction during the Covid-19 pandemic.
“I think it made a lot of people much more aware that they can take charge of their health,” she told Robb Report. Donnai is the founder of Viavi, a health management company that evaluates clients based on personal data ranging from DNA to lifestyle habits.
While Covid helped mainstream the idea, longevity’s roots stretch further back. Even before the pandemic, the concept had moved beyond sterile doctors’ offices into luxurious spaces that feel more like five-star resorts (and some are). Around the world, medical spas staffed with certified doctors and equipped with state-of-the-art facilities offer personalized health programs designed to optimize your physiology. These centers go far beyond massages and facials; they conduct medical-grade testing—including blood work—to build tailored regimens aimed at extending lifespan, detoxifying body and mind, and regenerating overall health.
In Switzerland, the Kusnacht Practice’s BIO-R approach evaluates clients on a biomolecular level to address chronic diseases, aging, and psychiatric conditions. Also in Switzerland, the Grand Resort Bad Ragaz offers hyperbaric oxygen therapy to reduce inflammation and boost energy production. Meanwhile, Chenot Palace Weggis, alongside its sister locations across the world, applies its renowned 50-year-old Chenot Method—a detox regimen that combines specialized treatments and diet plans—to eliminate toxins and promote overall wellness.
As Donnai points out, true success comes from individualized care, not a one-size-fits-all solution.”That’s why I set up Viavi: How can I actually really help an individual identify their risks? What do they need to change to really optimize their health and their well-being for as long as possible? . . . How can I give an individual a strategy for their health?
The world’s leading medical spas are answering those questions. Ahead, discover 13 spas and centers delivering premium, personalized health assessments, and strategies designed to help you live longer—and better.

Buchinger Wilhelmi | Überlingen, Germany
Image Credit: Winfried Heinze Therapeutic fasting is Buchinger Wilhelmi’s claim to fame, and the German clinic doesn’t disappoint. The process calls for you to eat about 200 to 300 calories a day throughout your stay (the recommended residency is at least 10 days for the effects to take hold properly), allowing your body to live off its fat reserves and leading to a massive regeneration—a.k.a., a giant reboot—of your cells and tissues. And this isn’t just a method to shrink your waistline: The pros at Buchinger say that fasting is able to improve your quality of life both now and in the future, acting as a safeguard against aging. In fact, one of our editors considers himself a convert to the process. Soon enough, you may be a believer, too.
