Couch potato warning

Posted by Kelsey Wheatcroft - email

(NBC) - While we generally tell people to sit down before hearing sobering news, in this case, stand up. Doctors say a sedentary lifestyle is deadly.

Many of us spend our workdays slouched over a desk, sitting in front of a computer.

We sit during our commute home, then we sit some more vegging out in front of the T.V. or computer.

Doctors say that's likely to bring our lives to an end sooner than we'd like.

Dr. Marc Gillinov at the Cleveland Clinic says, "People who are sedentary have increased inflammation just as a result of sitting. Perhaps it's something to do with less muscle contraction."

increased inflammation in the body is linked to heart disease, and a new study finds markers for inflammation were twice as high in people who spent more than four hours a day sitting in front of a computer or T.V.

They were also much more likely to suffer major cardiac problems and die prematurely.

Doctors say the solution is exercise, even if it's just taking the stairs instead of the elevator.
