Some people can’t stand working. Mark Ramirez works standing.
He is not a waiter or a factory worker. He is a senior executive at AOL. Ramirez could, if he wanted, curl into the cushiest leather chair in the office-supply catalog. No, thanks. He prefers to stand most of the day at a desk raised above stomach level.
“I’ve got my knees bent. I feel totally alive,” Ramirez said. “It feels more natural to stand. I wouldn’t go back to sitting.”
In the past few years, standing has become the new sitting for 10 percent of AOL employees at the company’s Dulles, Va., campus, part of a standing ovation among accountants, programmers, bureaucrats, telemarketers and other office workers across the nation.
Standers give various reasons for taking to their feet: It makes them feel more focused, prevents drowsiness, makes them feel like a general even if they just push paper. (Former Defense Secretary Donald Rumsfeld works standing up. So does novelist Philip Roth.) But unknown to them, a debate is percolating among ergonomics experts and public-health researchers about whether all office workers should be encouraged to stand — to save lives.
In academic papers with titles such as “Your Chair: Comfortable but Deadly,” doctors point to surprising new research showing higher rates of diabetes, obesity, heart disease and even mortality among people who sit for long stretches. A study this year in the American Journal of Epidemiology showed that among 123,000 adults followed over 14 years, those who sat more than six hours a day were at least 18 percent more likely to die during the period studied than those who sat less than three hours a day.
“Every rock we turn over when it comes to sitting is stunning,” said Marc Hamilton, a leading researcher on inactivity physiology at the Pennington Biomedical Research Center in Louisiana. “Sitting is hazardous. It’s dangerous. We are on the cusp of a major revolution about what we think of as healthy behavior in the workplace.”
He calls sitting “the new smoking.”
Not so fast, other experts say. Standing too much at work will cause more long- term back injuries — ask factory workers, they say. Incidences of varicose veins among women will increase. The heart will have to pump more. Alan Hedge, a noted ergonomics scholar at Cornell University in New York, went so far as to call standing at work “one of the stupidest things one would ever want to do. This is the high heels of the furniture industry.”
What everyone can agree on, though, is that we were not exactly built to sit.
“We were built to stand, to move, to walk,” said James Levine, a Mayo Clinic endocrinologist who is so fanatical about not sitting at work that he walks at 1 mph all day on a treadmill at his desk.
He’s the author of that “Comfortable but Deadly” paper, and in it, he provides a remarkable history of how we became a nation of sitters. The short version is that hunter-gatherers became agriculturists, the Industrial Revolution moved us into factories and the technological revolution moved us behind desks. And here we are, pecking away. Today’s offices run on so much data that for many workers, two computer monitors are standard issue.
“With creativity, a person can eat, work, reproduce, play, shop and sleep without taking a step,” Levine wrote. “Once enticed to the chair, we were stuck. Work and home alike: We do it sitting.”
But Hedge, the Cornell professor, isn’t a fan of a lot of standing.
“Making people stand all day is dumb,” he said. “Standing increases torso-muscle activity and spinal-disc pressure, increases the risk of varicose veins, increases the risk of carotid-artery disease and increases the load on the heart.”
The sensible and most cost-effective strategy, he said, is to sit in a neutral posture, slightly reclined, with the keyboard on a tray above the lap. This position promotes positive blood flow. Workers should then occasionally walk around, stretch and avoid prolonged periods at the desk. The key, he said, is movement, not standing.
“If you stand all day, you will be worse off than if you sit all day,” he said.
