Yes sitting at work is bad, but is standing actually better? - Health & wellness - The Boston Globe: "“Standing all day isn’t the answer,” said Alan Hedge, a design and ergonomics professor at Cornell University. “That’s where we were 100 years ago, and we needed to develop chairs to prevent curvature of the spine, backaches, and varicose veins.”
While standing still burns a few more calories as our hearts work harder to circulate blood upward, it also puts more strain on our veins, backs, and joints, especially if we’re overweight.
“Studies haven’t yet determined how much standing helps healthwise,” said Dr. I-Min Lee, an associate epidemiologist at Brigham and Women’s Hospital who has studied the risks of sedentary behavior. In population studies, researchers haven’t been able to determine whether the health benefits of reduced sitting time stem from moving around more or from standing still. And results on whether exercise reduces the health risks of sitting are conflicting.
A May study of nearly 17,000 Canadian adults found that those who reported the most time standing had a 33 percent lower risk of dying from any cause over 12 years compared to those who stood the least. But those who exercised at least two hours each week — even if they sat the rest of the time — enjoyed the same life-extending benefits as those who stood the most. The Harvard researchers, on the other hand, found in their study that regular exercise didn’t erase the increased death risk associated with prolonged sitting."
