3 . Are you sitting more than ever?     1     You’re probably sitting while reading this. Sometimes you sit when you are driving or attending a meeting. Other times you sit when you engage yourself in watching a movie or playing computer games. That’s undoubtedly a lot of sitting. The fact is, the amount of time spent sitting has increased over time.     2    

We know sitting too much is bad, and most of us naturally feel a little guilty after a long-time TV watching.     3     A study on nearly 8,000 adults suggests that there’s a direct relationship between the time spent sitting and our risk of early death of any cause. As the total sitting time increases, so does the risk of early death.

“Sit less, move more” is what the Heart Association encourages us to do.     4     It is like telling someone to just ”exercise“ without telling them how. Exercise guidelines are always more practical. For example, the Center for Disease Control recommends adults do exercise for two hours and 30 minutes every week, plus muscle strengthening activities two or more days a week. We need similar guidelines for sitting.

    5     “It would probably be like, for every 30 continuous minutes of sitting, stand up and move or walk for five minutes at a quick pace,” Diaz, the lead researcher said, adding that the study has put us a step closer to the satisfying guidelines. But more researches are needed to confirm their approach.
