Show off your downward dog while overlooking the French Alps at InnerCityYoga, where classes are held on a huge outdoor roof deck or in the sunlit studio, depending on weather. Geneva’s high concentration of expats are fond of the bilingual teachers (English and French) and renowned visiting instructors, as well as the individual showers, towel service, and the bio-sauna. If you're seeking another type of relaxation, L'École Occidentale de Méditation, located in Noisy Castle in Pâquis, offers several classes exploring the link between poetry and meditation, including free meditation classes on Mondays.
Brave the cold and join locals for a winter swim in Lake Geneva at the Bains des Pâquis ($23/day). Swimming in the lake is popular in the summer months, but winter swimming has surged in popularity recently. After you hop out of the water, immediately warm up in the bath’s two mixed saunas, Turkish bath, and two hammams (one for women only). The facility is fully equipped with lockers, hot showers, and hair-dryers, so once you're dry, find a nook near the large glass windows and soak up the winter sun.
Give traditional Chinese medicine a try at SinoSanté, a reputable chain of clinics in French-speaking Switzerland that specialize in treatments like plant-based phyto-therapy medicine (from $24) and tui na massage ($76). For something completely different, try moxibustion, a somewhat bizarre technique in which smoldering dried mugwort is attached to the ends of acupuncture needles before they're placed at various pressure points on the body.
