Tai Chi has proven benefits
In one study, the practice of Yang-style tai chi for one hour twice weekly for 12 to 24 weeks improved quality of life in patients with fibromyalgia. Studies have also shown that it improves function and reduces pain in knee arthritis. And in a randomized controlled trial from 2005 tai chi even improved sleep in older persons with moderate sleep problems!
