Exercise, less sitting time, linked to better sleep 少坐多動 或可改善睡眠

Insomniacs looking for a good night’s sleep may want to hit the treadmill, take a walk or play a game of golf or tennis, because a new report released on March 4 shows that exercise promotes good sleep, and the more vigorous the workout the better.

Just 10 minutes of exercise a day could make a difference in the duration and quality of sleep, the survey by the non-profit National Sleep Foundation showed.

“We found that exercise and great sleep go together, hand in hand,” Max Hirshkowitz, a sleep researcher and the chair of the poll task force, said in an interview.

“We also found a step-wise increase in how vigorous the quality is, in terms of how much you exercise. So if you say you exercise a lot, we found better sleep quality. For people who don’t exercise at all we found more sleep problems.”

Earlier research studies have shown the impact of exercise on sleep, but Hirshkowitz, who is a professor at Baylor College of Medicine in Houston, said the survey is the first to detail the benefits of exercise in a nationally representative poll of this size.

People who described themselves as exercisers reported better sleep than their more sedentary counterparts, although the amount of sleep, an average of just under seven hours on weeknights, was the same.
