Harvard Study Showing Yoga, Meditation Benefit Health

(Undated) -- Scientists are close to proving that yoga and meditation can ward off stress and sickness. Harvard psychiatrist John Denninger is leading a five-year study on how those ancient practices affect the genes and brain activity of people who are chronically stressed. Earlier this year, he and other researchers published a study showing how so-called mind-body techniques can switch on and off genes linked to stress and immune function. Denninger says meditation produces a true biological effect. He says the sorts of things that happen when a person meditates have effects throughout the body, not just in the brain. The World Health Organization estimates stress costs U.S. companies at least 300-billion dollars a year through low productivity, absenteeism, and turnover.
