問題詳情

四、閱讀測驗You may have heard on the news about why sitting is bad for your health. According to recent research, sitting downall day just might be one of the worst things you can do for your physical well-being. There was a time when standingdeskswere a curiosity. Although some people might have attempted to make this an office norm, it was seldom seen insidea regular office setting.Now, that's changed. In large part, this is due to researchshowing that the cumulative impact of sitting all day foryearsis associated with a range of health problems, from obesity to diabetes to cancer. Because the average office workerP.5spends approximately 6 hours sitting each day at his or her desk, some even describe the problematic phenomenon witha new phrase, maybesomewhat exaggerated: "Sitting is the new smoking."The detrimental health impacts of sitting—and the benefits of standing—appear to go beyond simple obesity. Manyresearch studieshave found that sitting for extended periods of time is correlated with reduced effectiveness in regulatinglevels of glucose in the bloodstream, part of a condition known as metabolic syndromethat dramatically increases thechance oftype 2diabetes.In addition, other studies arrived at the conclusion that for people already at risk of developingtype 2diabetes, the amount of time spent sitting could be a more important risk factor than the amount of time spent vigorouslyexercising.Scientific evidence that sitting is bad for the cardiovascular system goes all the way back to the 1950s.Since then,scientists have foundthat adults who spend two more hours per day sitting have a 125 percent increased risk of healthproblems related tocardiovascular disease, including chest pain and heart attacks. Other work hasfound that men whospend more than five hours per day sitting outside of work and get limited exercisewere at twice the risk of heart failureas those who exercise often and sit fewer than two hours daily outside of the office.
