After several years of studies and stories proclaiming that "sitting is the new smoking," according to an even newer study, it's actually standing that will kill you. Whoops. Got that one wrong.
The study, published in the American Journal of Epidemiology, followed 7,000 participants over 12 years, and found that people whose jobs require frequent standing were almost twice as likely to develop heart disease. They were also more likely to be obese.
But before you return your standing desk, take note: Jobs that require standing—food service, factory work, manual labor—often come along with another seriously detrimental condition: poverty. When people don't have money, they are more likely to eat shit food, smoke shit cigs, and forgo luxuries like the climbing gym. But it's not just the economics—and you may want to sit down before you read this—according to study author Peter Smith, "standing too long can result in blood pooling in the legs, increased pressure in the veins and increased oxidative stress, all of which can contribute to an increased risk."
So, what's the answer? Should you sit or should you stand? Both. For optimal health, you should sit for 15 minutes and then do jumping jacks for 15 minutes, all day, every day. Ignore your coworkers—they're just jealous of your physique. And if you can't do that, get some Rollerblades, take frequent bathroom breaks, and maybe petition your neighborhood grocery to let their cashiers sit down. Study says: They need it.
