Practitioners of tai chi have, for a long time, claimed that tai chi brings about health benefits. Indeed, in the last few years preliminary medical studies involving immunity to the herpes zoster virus in the elderly seemed to indicate that. Now a recent follow-up study funded by the National Institute of Health has demonstrated that “behavioral intervention” can help protect older adults from the virus, which causes both chickenpox and shingles.
In the clinical trial, that behavioral intervention was the practice of tai chi.
