While there is no evidence documenting any serious risks or side effects associated with Qigong, exercise routines of any kind always carry the possibility that the practitioner may fall or injure themselves if they aren’t careful. Qigong and Tai Chi, however, use slower, controlled movements that reduce that possibility compared to more intense forms of exercise. Despite this, both are not proven to be substitutes for medical treatments, so medical issues should still be taken care of by medical professionals.
