There’s more and more research being conducted and presented about the detrimental effects of sitting and positive effects of standing. A study at the University of Massachusetts showed that volunteers who stood for several hours a day burned hundreds of calories more than the same volunteers who sat for the same amount of time during the day. Instead of sitting to watch TV, try standing or exercising while watching your favorite TV show. Even if one exercises a great deal (people who exercise often sit around more than they otherwise would while not exercising according to another study). DNA repair mechanisms are enhanced, insulin response increases, oxidative stress drops, blood sugar levels remain stable or drop, and metabolic activity remains higher or increases. Here are some ideas you can implement rather easily to incorporate standing into your daily routine: (1) Stand on one foot while brushing your teeth; (2) Walk around while talking on the telephone; (3) Walk, don’t drive, on short errands. But, whatever your age, motion will improve your physical fitness and your over-all health.
And with that said there’s other research from Lifehacker via Cornell scientist that suggests sitting to do computer work is preferable to standing. Sit using a height-adjustable, downward titling keyboard tray for the best work posture, then every 20 minutes stand for 2 minutes AND MOVE. The absolute time isn’t critical but about every 20-30 minutes take a posture break and move for a couple of minutes. Simply standing is insufficient. Movement is important to get blood circulation through the muscles. Research shows that you don’t need to do vigorous exercise (e.g. jumping jacks) to get the benefits, just walking around is sufficient. So build in a pattern of creating greater movement variety in the workplace (e.g. walk to a printer, water fountain, stand for a meeting, take the stairs, walk around the floor, park a bit further away from the building each day).
