Study: Tai chi may help prevent shingles

Tai chi is already known as a good low-impact exercise for older people. Now a recent study suggests it offers benefits beyond improving fitness and balance: It may help prevent shingles, a painful skin condition.

Researchers found older people who performed the slow, graceful movements of tai chi had a better immune response against the virus that causes shingles than those who only got health education, according to the most rigorous test to date.
