Stand-Up Desks Gaining Favor in the Workplace. As more research finds health hazards in sitting for prolonged periods, more manufacturers are offering desks that let workers stand, or even walk, while toiling at the keyboard.
THE health studies that conclude that people should sit less, and get up and move around more, have always struck me as fitting into the “well, duh” category.
But a closer look at the accumulating research on sitting reveals something more intriguing, and disturbing: the health hazards of sitting for long stretches are significant even for people who are quite active when they’re not sitting down. That point was reiterated recently in two studies, published in The British Journal of Sports Medicine and in Diabetologia, a journal of the European Association for the Study of Diabetes.
Suppose you stick to a five-times-a-week gym regimen, as I do, and have put in a lifetime of hard cardio exercise, and have a restingheart rate that’s a significant fraction below the norm. That doesn’t inoculate you, apparently, from the perils of sitting….
Standing for prolonged periods is also bad for you. The Cornell Human Factors and Ergonomics Research Group has put up a good summary of the risks of standing desks and the risks of sitting desks, available here. Here’s their conclusion:
Sit to do computer work. Sit using a height-adjustable, downward titling keyboard tray for the best work posture, then every 20 minutes stand for 2 minutes AND MOVE. The absolute time isn’t critical but about every 20-30 minutes take a posture break and move for a couple of minutes. Simply standing is insufficient. Movement is important to get blood circulation through the muscles. And movement is FREE! Research shows that you don’t need to do vigorous exercise (e.g. jumping jacks) to get the benefits, just walking around is sufficient. So build in a pattern of creating greater movement variety in the workplace (e.g. walk to a printer, water fountain, stand for a meeting, take the stairs, walk around the floor, park a bit further away from the building each day).
