Office workers who spend all day behind their desks should consider working standing up instead, according to a new research.

Staying on your feet for an extra three hours a day would burn offP 8 pounds (3.6 kg) of fat each year, according to exercise scientist John Buckley from Chester University. He said there is no need to sit down so much and those feeling tired would do well to push their chairs away during the day.

Dr. Buckley added that people could work at desks higher than normal computer to answer e－mails and type documents. An uprightW1 working posture was championed by author Ernest Hemingway who wrote on a typewriter at a special chest－height desk. In a letter in 1950, Hemingway wrote, "Writing and travel broaden your ass if not your mind and I like to write standing up."

Dr. Buckley, from the department of Clinical Sciences and Nutrition at Chester University, said that working standing up will reduce obesity and improve circulationW2. Standing up for three hours will consume 144 calories, he claims. "People are sitting down at work, then sitting in the car and then sitting down in front of the television，" Dr. Buckley told BBC News. Dr. Buckley is part of a group of experts working with England's chief medical officer on ways to deal with obesity.

A study late last year made a strong connection between too much sitting down and an increased risk of diabetes(糖尿病). Meanwhile, a major Australian study published in March 2012 found sitting down too long increases your risk of dying within a few years-even if you are already physically active.

It found adults who sat 11 or more hours per day had a 40 percent increased risk of dying in the next three years compared with those who sat for fewer than four hours a day.

Dr. Buckley concludedW3 making small changes in the workplace such as standing at your disk can make long－term improvements to your health.

研究表明，人长期坐着不仅容易生病，而且会过早地死亡，所以专家建议，要尽可能地减少坐着的时间，增加站立的时间，这样不仅有益健康，也会有明显的
