Instead of hitting the gym, that greasy burger or another afternoon shot of espresso this noon hour, trying taking a walk. You may like your job a bit more because of it.

A new study shows that "lunchtime walks improved enthusiasm, relaxation, and nervousness at work." The research was published in the Scandinavian Journal of Medicine and Science in Sports, and was done by research at the University of Birmingham and other universities.

You don't even have to walk fast or hard. You don't need to take the stairs or break a sweat. It's enough to take a leisurely walk.

As the New York Times points out, it's not exactly earth-shattering news that walking is healthy, and the walkers among us are calmer, happier and more alert than our more sedentary brothers and sisters.

"But many past studies of the effects of walking and other exercise on mood have focused on somewhat long-term, gradual outcomes, looking at how weeks or months of exercise change people emotionally," the Times wrote. "Fewer studies have examined more-abrupt, day-to-day and even hour-by-hour changes in people’s moods, depending on whether they exercise, and even fewer have focused on these effects while people are at work, even though most of us spend a majority of our waking hours in an office."

So let's get happy and take a walk.
