When working at home, it's good to have a break, possibly every 30 minutes, to stay healthy and minimize injury to your back, shoulders and arms, says Kermit Davis, PhD, an expert in office ergonomics at the University of Cincinnati College of Medicine.

"The body doesn't like static postures continually," says Davis, a professor in the UC Department of Environmental and Public Health Sciences. "You don't want to do all sitting or all standing all the time. You want to alter your position and change it up throughout the day."
