T'ai chi, an exercise that features slow martial arts-like movements and meditation, significantly improves the ability of older adults' immune systems to fight the virus - varicella zoster - that causes shingles, a new study says.

Shingles is a painful, blistery rash. About one-third of adults over age 60 develop shingles.
As good as vaccine
The 25-week study, conducted at the University of California, Los Angeles, involved 112 people, ages 59 to 86. The Researchers found that T'ai chi, by itself, increased immunity against varicella zoster to a level that was comparable to having received the standard vaccine against the virus.
When a person did T'ai chi and received the vaccine, the immunity against the virus reached a level normally seen in middle age, said the study, which was published in the April issue of the Journal of the American Geriatrics Society.
The study results confirm that a behavioural intervention such as T'ai chi can trigger a positive, virus-specific immune response, said lead author Michael Irwin, professor of psychiatry at the Semel Institute for Neuroscience and Human Behaviour at UCLA.
"These are exciting findings, because the positive results of this study also have implications for other infectious diseases, like influenza and pneumonia. Since older adults often show blunted protective responses to vaccines, this study suggests that T'ai chi is an approach that might complement and augment the efficacy of other vaccines, such as influenza," Irwin, who is also director of the UCLA Cousins Centre for Psychoneuroimmunology, said in a prepared statement. – (HealthDayNews)
