''Many of the students I teach do it for that,'' Sheaffer said.
''It is very relaxing,'' said Priscilla Finnell of Spencer Drive after her first class with Sheaffer following a one-year layoff from tai chi.
''I noticed how my balance was better,'' said Finnell, who is in her early 70s. ''I feel better doing it.''
''It helps center you,'' said Susan Brown, 51, of Maceo, who grew up in Hawaii intrigued by watching a large Asian population practice the Chinese-born discipline.
She joined Sheaffer's class at the urging of friend Katherine Howell, 48, a former student of Sheaffer's who is seeking relief from a stressful job.
''For me, it was a way to get back in an exercise program'' following a 12-year layoff because of work, building a house and laziness, Howell said.
Besides breathing, part of tai chi's calming influence comes from a full-body workout even though the constant, deliberate movements are cold-taffy slow.
Many of those movements involve twisting the body, relieving stress on the muscles by the heart, spleen, lungs, kidneys, liver and other organs, Sheaffer said.
''You can actually massage those organs in your body,'' she said.
Muscles get toned and bone density improves since it is considered a weight-bearing exercise, Meeks said.
Research shows it helps the autoimmune system, bringing relief from diabetes, cancer fatigue, high blood pressure, lupus and other conditions, he said.
''It's not a cure, but it helps. It relieves some of the symptoms of those illnesses,'' Meeks said. ''It helps you naturally realign the body.''
Because every joint is involved, ''it's good for older people with arthritis or joint problems,'' said Sheaffer, who can modify movements for older students if needed.
Sheaffer found tai chi a good therapy after a 41-year hairstyling career left her with arthritis in both shoulders and two rotator cuff surgeries.
''It's a smooth transition from having surgery to get your range of motion back,'' she said. ''I've found how you can get in better shape than before surgery.''
Meeks is helping plan a 2009 international symposium that will bring together masters of five tai chi styles for seminars, training and research comparison.
The event, which will likely be in Louisville, will also be a cultural exchange that will help promote tai chi and its benefits to any age, economic background or fitness level, he said.
