Work. Walk 5 Minutes. Work.

Stuck at your work desk? Standing up and walking around for five minutes every hour during the workday could lift your mood, combat lethargy without reducing focus and attention, and even dull hunger pangs, according to an instructive new study.

The study, which also found that frequent, brief walking breaks were more effective at improving well-being than a single, longer walk before work, could provide the basis for a simple, realistic New Year’s exercise resolution for those of us bound to our desks all day.

There is growing evidence, of course, that long bouts of uninterrupted sitting can have undesirable physical and emotional consequences. Studies have shown that sitting motionless reduces blood flow to the legs, increasing the risk for atherosclerosis, the buildup of plaques in the arteries.

People who sit for more than eight or nine hours daily, which for many of us describes a typical workday, also are at heightened risk for diabetes, depression and obesity compared with people who move more often.
