Adverse effects of tai chi are rarely reported and may include sore muscles or sprains. Tai chi should be avoided by people with severe osteoporosis or joint problems, acute back pain, sprains, or fractures. Advancing too quickly while studying tai chi may increase the risk of injury.
Tai chi instructors sometimes recommend that practice be avoided during active infections, right after a meal, or when very tired. Some believe that visualization of energy flow below the waist during menstruation may increase menstrual bleeding. Straining downwards or holding low postures should be avoided during pregnancy and by people with inguinal hernias. Some tai chi practitioners believe that practicing for too long or using too much intention may direct the flow of chi (qi) inappropriately, possibly resulting in physical or emotional illness.
Tai chi should not be used as a substitute for more proven therapies for potentially serious conditions. Individuals should consult a qualified healthcare professional if they experience dizziness, shortness of breath, chest pain, headache, or severe pain while practicing tai chi.
