From the early morning, I sit, glued to the chair in front of my computer, even for hours sometimes. 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.
A group of office workers who almost sit got involved in the research, all 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, many of the volunteers weren’t confident that they’d continue walking after the study, mainly because they were expected to work through their lunch breaks. Understandable, sad.

Many studies have hinted(暗示) that alcohol, in moderation, can do a heart good. But new research suggests that moderate drinkers are no more likely than nondrinkers to have clear arteries(动脉).
The scientists looked at almost 2,000 patients who underwent CT test. Overall, there was no association between people’s drinking habits and their heart diseases. Researchers said an advantage of the new study is that it used objective measurements.
“No prior studies have assessed the relationship between alcohol consumption and the presence of heart disease,” said lead researcher Dr Julia Karady. “We could not find any relation between the presence of heart disease and alcohol consumption,” Karady said. At the same time, she added, there was no evidence that heavier drinking raised the risk of heart disease.
However, groups like the American Heart Association(AHA) warn against excessive drinking, because it can raise blood pressure and contribute to heart failure and other problems.
In general, “moderate” is defined as no more than one glass of alcohol a day for women, and no more than two a day for men. But those studies do not prove that alcohol, itself, protects the heart—in large part because alcohol also carries risks.

Relaxation Techniques
Reach out.
Your social network is one of your best tools to handle stress.
Be present.
Slow down. Take 5 minutes and focus on only one behaviour with awareness. Notice how you feel the air blow on your face when you’re walking and how you feel when your feet are hitting the ground. Enjoy the taste of each bite of food.
Breathe deeply.
Take a 5-minute break and focus on your breathing. Sit up straight, eyes closed.
A laugh doesn’t just lighten the load mentally. It lowers your body’s stress hormone (荷尔蒙), and boosts brain chemicals which help lighten your mood. Lighten up through tuning to your favourite sitcoms or videos, reading the comics or chatting with someone who makes you smile.
Get moving.
| A．Laugh out loud. |
| B．You don’t have to run in order to get a runner’s high. |
| C．Laugh as much as possible to relieve your sense of stress. |
| D．Talk to others, preferably face to face, or at least on the phone. |
| E．Singing aloud will help you relieve negative thoughts and worries. |
| F．Slowly breathe in the air through your nose and breathe it out through your mouth. |
| G．When you spend time on the moment and focus on your senses, you would feel less tense. |
