问答题 1.  Spending hours a day sitting at a desk is known to have consequences for your health, but scientists now say just five-minute walking stints could counteract some of the risks. In a new study, researchers found that taking brief, repeated breaks from work to stand up and move around has sustained benefits for your mood and energy levels. The effects of these microbouts of activity were found to last all day, and could even help to alleviate food cravings while you're at work.
    "Office workers have been identified as one of the most vulnerable occupational groups for accumulating prolonged and uninterrupted sitting time," the authors explained in the study, published to the International Journal of Behavioral Nutrition and Physical Activity. And, this sedentary lifestyle increases the risks of diabetes, depression, and obesity, among other health concerns.
