I start my workday early, parking myself in front of my home computer and often forgetting to get up for hours. But one thing I try to do every day is take a ten-minute walk around midday.
Walking at lunchtime is a smart thing to do, a new study finds. This doesn't seem like news. After all, we've known forever that doing exercise is good for us. But as The New York Times points out, those fitness studies typically looked at the effects of exercise plans in the long run. This new study looks at changes that happen more quickly, from one day to the next or even from this hour to the next hour.
For the study, researchers gathered a group of mostly sedentary(久坐的) office workers in the UK. All were out of shape, but otherwise emotionally and physically healthy. Researchers asked them to take 30-minute lunchtime walks, three days a week for 10 weeks. The volunteers were also asked to install apps on their phones, so that the researchers could send the volunteers questions after they walked. Then the researchers used those answers to judge how the volunteers were feeling about life and work, and to measure their feelings about everything from stress and tension to motivation.
When the researchers compared the volunteers' answers on the afternoons when they walked to those on the afternoons they didn't walk, there was quite a difference. On the days when they had a lunchtime walk, the volunteers said they felt less stressed, more energetic and more relaxed versus(与……相对) on the days when they didn't walk.
Unfortunately, the researchers said many of the volunteers didn't believe they'd be able to continue walking once the study ended, mainly because they were expected to work through
their lunch breaks. It's an understandable response, but a sad one.
