Office workers should know that long periods of sitting at your desk may be a killer. Scientists have shown a new threat from this lifestyle that they call  “muscular inactivity (肌肉迟钝)”.

Sitting still for long periods of time leads to the buildup of substances (物质) in the blood that are harmful to health. And exercise alone won’t drive them away.

Millions of people spend their days between car,office desk and the sofa in front of the TV. While the bad influences are well rocognized,it has been thought that they can be changed by regular trips to the gym or swimming pool.

Now researchers say that is not enough. In addition to regular exercise,office workers need to keep moving while they work,by making regular trips to the printer,coffee machine or to chat with workmates.

Elin Ekblom­Bak,an expert on health,says research shows long periods of sitting and lack (缺乏)  of “whole body muscular movement”  are strongly linked to obesity,heart disease and cancer,and a higher risk of death,regardless of (不管) whether they take enough exercise.

“Everyone knows about the health benefits of regular exercise. But what we haven’t realized before is that long­period sitting down carries an extra risk that cannot be dealt with by taking exercise,” Dr Ekblom­Bak said,adding that sitting still should be recognized as a risk to health.

“It is important to have a five­minute break from desk work every 45 minutes. Don’t email workmates—walk across the office to give them the message. Take a coffee break or put the printer in the next room. I am a desk worker and I try to do it. It is not difficult but sometimes you get lost in your work and you forget about it.”

However,more studies are needed to confirm the ill effects of sitting for too long and ways of fighting them. But at present they conclude that  “keep moving”  should be added to the advice to “keep exercising.”

A.long periods of sitting has bad influences on them

  Like so many girls of my generation, I went straight from college to society.Through my family's attempt, I found my suitable job.I thought I was doing a great job.

  One day, a female program director arrived at the station.This large and frightening woman came to work every day with an equally large and frightening German dog.She didn't like me.When she called me into her office one Friday afternoon, she simply said,“You're fired!”leaving me to wonder what had gone so terribly wrong.

  Six months later, after calling every program director in town, I went to work for another major-market radio station, doing four-minute stories for a low $15 each.With two young children and a husband who was just starting his own career, I took a chance.

  Today, some 28 years later, I am still at WOR Radio with a two-hour daily talk show interviewing celebrities, authors and politicians, giving information to more than a million listeners a week and loving every minute of it.

  I was young when those firings happened, but the process is still the same.Firings know no age or gender.The trick is to get out from under the covers and make things happen.This is exactly what Sherrye Henry did.
