More than 34 million in the U.S. practice yoga and other mind-body therapies

About 1 in 7 people in the U.S. now do some form of mind-body therapylike yoga, qiqong, or tai chi, triple the number almost 20 years ago. Researchers, using information from National Health Interview Surveys beginning in 2002: More people in recent years said they use the practices to help with depression and anxiety, instead of pain. Although the study has limitations — including relying on people to recall their activities from memory — the authors say that the results may complement studies that are testing the use of yoga, tai chi, and qiqong for possible medical benefits.
