【推荐1】Here’s a new warning from health experts: sitting is deadly. Scientists are increasingly warning that sitting for long periods, even if you exercise regularly, could be bad for your health. And it doesn't matter where the sitting takes place--in the office, at school, in the car or before a computer or TV. Just the overall number of hours it takes matters. Several studies suggest people who spend most of their days sitting are more likely to be fat, have a heart attack or even die. While health officials have issued(发布) guidelines advising on the least amounts of physical activities, they haven’t suggested people try to limit how much time they spend in a seated position.
“After four hours of sitting, the body starts to send harmful signals,” said Ekblom-Bak of the Swedish School of Sport and Health Sciences. She explained that genes controlling the amount of glucose(葡萄糖) and fat in the body start to shut down.
Even for people who exercise, spending long periods of time sitting at a desk is still harmful. Tim Armstrong, a physical activity expert at the World Health Organization, said people who exercise every day but still spend a lot of time sitting might get more benefits if that exercise were spread across the day, rather than in a single hour.
Still in a study that tracked more than 17,000 Canadians for about a dozen years, researchers found people who sat more had a higher death risk, whether they exercised or not. Experts said more research is needed to figure out just how much sitting is dangerous, and what might be possible to offset those effects.
People should keep exercising because that has a lot of benefits,” Ekblom-Bak said. “And when they’re in the office, they should try to interrupt sitting as often as possible.”
