Doctors Conclude Reclining is Best for Back

Back pain is the number one cause of absentism at work. In fact, it's the leading cause of disability in Anmerica. Doctors at the Woodend Hospital in Aberdeen, Scotland conducted a study on 22 people with no previous history of back pain. They used positional MRI, which allows the patients to move from various positions during the test. They concluded that sitting upright at a 90 degree angle puts unwanted stress on the spinal cord. The optimal position to sit in was actually 135 degrees or a reclining position. The doctors suggest sitting in a reclined position can help prevent back problems in the future. Also, they feel companies could change their sitting situations to avoid the loss of work hours. I think it's funny to imagine people working in a reclined position.
