The Wall Street Journal reports that Alan Hedge, a professor of ergonomics at Cornell University, confirms “For every half-hour working in an office, people should sit for 20 minutes, stand for eight minutes and then move around and stretch for two minutes.” This is “based on a review of studies that he has presented at corporate seminars and expects to publish.”

The post states: “The British Journal of Sports Medicine earlier this year published guidelines for sitting from an international panel of experts, including Dr. Hedge. The panel recommends a combined two to four hours of standing and light activity spread throughout the workday. And research from NASA has found that standing up for two minutes 16 times a day while at work is an effective strategy for maintaining bone and muscle density.”
