What tai chi is
Tai chi is a practice built from a series of slow, gentle movements and postures, a meditative state of mind and controlled breathing. [1] The movements are usually circular and never forced, and the muscles are relaxed rather than tensed. [2]Origins and styles
Tai chi began as a martial art in China and has become more focused over time on health promotion and rehabilitation. [1] Branches are named for people who devised sets of movements, called forms; examples are Yang, Wu and Cheng. [2] Some programs stress the martial side, others healing and stress reduction. [2] The sources read for this page do not give dates or a single origin story, so none is offered here.The traditional explanation
In the traditional Chinese framework, qi is an energy force thought to flow through the body, and tai chi is said to unblock it. Yin and yang are opposing elements said to need balance. [2] These are traditional ideas, not measured biological mechanisms. You do not need to subscribe to Chinese philosophy to enjoy tai chi's health benefits. [2] For context see what is traditional Chinese medicine.What a class involves
A class often starts with a warm-up of easy motions such as shoulder circles and gentle rocking. [2] Then comes practice of forms. Short forms may have a dozen or fewer movements, long forms hundreds, and a short form with small, slow movements is usually suggested first. [2] A class may also include a qigong segment of gentle breathing, sometimes with movement. [2] Most teachers let you watch a class first. [2] Programs tested in research usually last at least 12 weeks, with instruction once or twice a week. [2] By then you should know whether you enjoy it. [2]What research shows
Tai chi cannot be hidden from participants, so benefits in trials against usual care may partly reflect attention and expectation. Labels: established, promising but limited, mixed, insufficient evidence. Evidence below is NCCIH's summary of published reviews.| Question | What the sources found | Label |
|---|---|---|
| Fewer older adults falling | Compared with controls not thought to reduce falls, tai chi may cut the number of people who fall by 20% (high certainty, 8 studies, 2,677 people) and the rate of falls by 19% (low certainty). Balance and functional exercise also helped. [1] | established, but other exercise works too |
| Knee and hip osteoarthritis | A 2019 US guideline strongly recommends tai chi. [1] | established recommendation |
| Low back pain | A review of 10 studies (959 people) cautiously concluded tai chi may reduce pain and improve function. [1] | promising but limited |
| Fibromyalgia | Reduced pain scores in a six-study review; larger studies are needed. [1] | promising but limited |
| Rheumatoid arthritis | Uncertain whether it reduces pain or disease activity. [1] | insufficient evidence |
| COPD | May improve exercise capacity, lung function and quality of life. [1] | promising but limited |
| Type 2 diabetes | Better than no exercise for blood glucose measures, but not better than other aerobic exercise. [1] | mixed |
| High blood pressure | A 28-study review found benefits, but the studies were of poor quality. [1] | insufficient evidence |
| Cancer-related symptoms | Promising, but no definite conclusions can be made. [1] | promising but limited |
In Parkinson's disease, tai chi may help balance and falls. [1] For side-by-side questions see tai chi vs qigong and yoga vs tai chi.
Safety
A review of 24 studies (1,794 people) found adverse events were as frequent with tai chi as with other active interventions or none, and those linked to it were minor, such as aches and pains. [1] If you have a limiting musculoskeletal problem or medical condition, or take medicines that can cause dizziness, check with your care team first. [2] No published studies on tai chi's safety in pregnancy exist; talk with your health care provider before starting. [1]Teachers and training
In the United States tai chi instructors do not have to be licensed, and neither federal nor state governments regulate the practice. There is no national certification standard. [1] Ask about training and experience and ask to watch a class. [1][2] Rules elsewhere were not checked.See a clinician first when needed
Do not use tai chi to postpone seeing a health care provider about a medical problem. [1] Adjustments for older adults and limited mobility are in adapted yoga and movement, and the overview is Yoga & Movement.Frequently asked questions
Is tai chi a martial art or exercise?
Both. It began as a martial art in China and now often focuses on health. [1] Some programs emphasize martial arts, others healing and stress reduction. [2]
Do I need to believe in qi?
No. Harvard Health says you do not need to subscribe to tai chi's roots in Chinese philosophy to enjoy its health benefits. [2]
How long before I notice a difference?
Research programs usually last at least 12 weeks; by then you may notice physical and psychological changes. [2]
Does tai chi help prevent falls?
In older adults, a review summarized by NCCIH found it may reduce the number of people who fall by 20 percent (high-certainty evidence), though other balance exercise also helped. [1]
Is tai chi safe for older adults?
It appears safe; reported problems were minor aches and pains. [1] Check with your care team if you have health problems or dizzying medicines. [2]
Does a tai chi teacher need a license?
Not in the United States. [1]
