Sedentary Lifestyle Accelerates Aging

Active people biologically younger than couch potato set, British study suggests. People who are physically active in their free time may be biologically younger than couch potatoes, a new British study suggests.

"A sedentary lifestyle increases the propensity to aging-related diseases and premature death. Inactivity may diminish life expectancy not only by predisposing to aging-related diseases, but also because it may influence the aging process itself," study author Lynn F. Cherkas, of King's College London, said in a prepared statement.

"The U.S. guidelines recommend that 30 minutes of moderate-intensity physical activity at least five days a week can have significant health benefits," they wrote. "Our results underscore the vital importance of these guidelines. They show that adults who partake in regular physical activity are biologically younger than sedentary individuals. This conclusion provides a powerful message that could be used by clinicians to promote the potential anti-aging effect of regular exercise."

The study was published in the Jan. 28 issue of the Archives of Internal Medicine. http://archinte.ama-assn.org/
