Try This Sit-Stand Formula for Every 30 Minutes at Work Is this the secret for keeping your desk job from killing you? By Michael Harthorne, Newser Staff Posted Sep 30, 2015 6:20 PM CDT 14 comments Comments (Shutterstock) (Newser) – By now, it's been thoroughly reported that sitting too much at work can kill you, increasing your risk of everything from cancer to diabetes. But standing too much isn't any better, potentially leading to varicose veins, back problems, and more. Now, one ergonomics professor says he's figured out the exact right balance to encourage a long, healthy life for the average office drone. Cornell University's Alan Hedge tells the Wall Street Journal for every half hour you work, you should sit for 20 minutes, stand for eight, and move around and stretch for two. “The key is breaking up your activity throughout the day,” he says. “Sitting all day and standing all day are both bad for you." Hedge plans on publishing his findings sometime in the future.
