Tai chi, which originated in China as a martial art, is a mind-body practice in complementary and alternative medicine (CAM). Tai chi is sometimes referred to as "moving meditation"—practitioners move their bodies slowly, gently, and with awareness, while breathing deeply. This Backgrounder provides a general overview of tai chi and suggests sources for additional information.
Many people practice tai chi to improve their health and well-being.
Scientific research is under way to learn more about how tai chi may work, its possible effects on health, and chronic diseases and conditions for which it may be helpful.
Tell your health care providers about any complementary and alternative practices you use. Give them a full picture of what you do to manage your health. This will help ensure coordinated and safe care.
Tai chi developed in ancient China. It started as a martial art and a means of self-defense. Over time, people began to use it for health purposes as well.
Accounts of the history of tai chi vary. A popular legend credits its origins to Chang San-Feng, a Taoist monk, who developed a set of 13 exercises that imitate the movements of animals. He also emphasized meditation and the concept of internal force (in contrast to the external force emphasized in other martial arts, such as kung fu and tae kwon do).
The term "tai chi" (shortened from "tai chi chuan") has been translated in various ways, such as "internal martial art" and "supreme ultimate fist." It is sometimes called "taiji" or "taijiquan."
Tai chi incorporates the Chinese concepts of yin and yang (opposing forces within the body) and qi (a vital energy or life force). Practicing tai chi is said to support a healthy balance of yin and yang, thereby aiding the flow of qi.
People practice tai chi by themselves or in groups. In the Chinese community, people commonly practice tai chi in nearby parks—often in early morning before going to work. There are many different styles, but all involve slow, relaxed, graceful movements, each flowing into the next. The body is in constant motion, and posture is important. The names of some of the movements evoke nature (e.g., "Embrace Tiger, Return to Mountain"). Individuals practicing tai chi must also concentrate, putting aside distracting thoughts; and they must breathe in a deep and relaxed, but focused manner.
Use in the United States
According to the 2007 National Health Interview Survey, which included a comprehensive survey of CAM use by Americans, an estimated 2.3 million U.S. adults had used tai chi in the past 12 months.
People practice tai chi for various health-related purposes, such as:
For benefits associated with low-impact, weight-bearing, aerobic exercise
To improve physical condition, muscle strength, coordination, and flexibility
To improve balance and decrease the risk of falls, especially in elderly people
To ease pain and stiffness—for example, from osteoarthritis
To improve sleep
For overall wellness.
The Status of Tai Chi Research
Scientific research on the health benefits of tai chi is ongoing. Several studies have focused on the elderly, including tai chi's potential for preventing falls and improving cardiovascular fitness and overall well-being. A 2007 NCCAM-funded study on the immune response to varicella-zoster virus (the virus that causes shingles) suggested that tai chi may enhance the immune system and improve overall well-being in older adults. Tai chi has also been studied for improving functional capacity in breast cancer patients and quality of life in people with HIV infection. Studies have also looked at tai chi's possible benefits for a variety of other conditions, including cardiovascular disease, hypertension, and osteoarthritis. In 2008, a review of published research, also funded by NCCAM, found that tai chi reduced participants' blood pressure in 22 (of 26) studies.
In general, studies of tai chi have been small, or they have had design limitations that may limit their conclusions. The cumulative evidence suggests that additional research is warranted and needed before tai chi can be widely recommended as an effective therapy.
Side Effects and Risks
Tai chi is a relatively safe practice. However, there are some cautions:
As with any exercise regimen, if you overdo practice, you may have sore muscles or sprains.
Tai chi instructors often recommend that you do not practice tai chi right after a meal, or when you are very tired, or if you have an active infection.
If you are pregnant, or if you have a hernia, joint problems, back pain, fractures, or severe osteoporosis, your health care provider may advise you to modify or avoid certain postures in tai chi.

Tai Chi & Qi Gong for Health and Well-Being Video
[14min 09sec; also viewable as 5 separate chapters]
This video is intended to be an educational tool that features tai chi and qi gong as an activity to enhance wellness. These exercise therapies are generally considered safe, self-care approaches used to promote a healthy lifestyle. As always, talk to your health care provider if you are using or considering using any complementary health practices so that they can help safely coordinate your care.
Training, Licensing, and Certification
Tai chi instructors do not have to be licensed, and the practice is not regulated by the Federal Government or individual states. In traditional tai chi instruction, a student learns from a master teacher. To become an instructor, an experienced student of tai chi must obtain a master teacher's approval. Currently, training programs vary. Some training programs award certificates; some offer weekend workshops. There is no standard training for instructors.
If You Are Thinking About Practicing Tai Chi
Do not use tai chi as a replacement for conventional care or to postpone seeing a doctor about a medical problem.
If you have a medical condition or have not exercised in a while, consult with your health care provider before starting tai chi.
Keep in mind that learning tai chi from a video or book does not ensure that you are doing the movements correctly and safely.
If you are considering a tai chi instructor, ask about the individual's training and experience.
Look for published research studies on tai chi for the health condition you are interested in.
Tell all your health care providers about any complementary and alternative practices you use. Give them a full picture of what you do to manage your health. This will help ensure coordinated and safe care. For tips about talking with your health care providers about CAM, see NCCAM's Time to Talk campaign.
