Question

How many hours do you spend sitting in a chair every day? Eight hours in the office and three hours in front of the TV after work is the normal condition for many people.

You probably don't need an expert to tell you that sitting too much is not good for your health, but the following fact can tell you more.

A study showed the health of 123,000 Americans between 1992 and 2006. The death rate（比率）for men who spent six hours or more per day sitting was about 20 percent higher than for men who sat for three hours or less. The death rate for women who sat for more than six hours a day was about 40 percent higher ①．

In other words, ② ．

So what can we do about it? Health experts suggest we spend more hours standing instead of sitting.

The BBC and the University of Chester in the UK did a simple experiment with a small group of 10 volunteers who usually spent most of the day sitting. They were asked to stand for at least three hours a day. The researchers took records on days when the volunteers stood, and when they sat around. As a result, there were some great differences, the BBC reported on Oct 16.

The researchers believe that even small movements, like standing while talking on the phone, going over to talk to a workmate rather than sending an e-mail, or simply taking the stairs instead of lift, will help.
