Medical experts are devising formulas for how long a typical office worker should spend sitting and standing to counter the negative health effects of being sedentary.
In The Wall Street Journal: “The Price We Pay For Sitting Too Much”
New research is helping medical experts devise formulas for how long a typical office worker should spend sitting and standing.
Studies have found that sedentary behavior, including sitting for extended periods, increases the risk for developing dozens of chronic conditions, from cancer and diabetes to cardiovascular disease and nonalcoholic fatty liver disease. Some ergonomics experts warn that too much standing also can have negative effects on health, including a greater risk for varicose veins, back and foot problems, and carotid artery disease.
“The key is breaking up your activity throughout the day,” said Alan Hedge, a professor of ergonomics at Cornell University. “Sitting all day and standing all day are both bad for you,” he said.
Standing burns one-half to one calorie more a minute than sitting. In four hours, that represents as many as 240 additional calories burned. Sitting more than an hour lowers the levels of the enzyme lipoprotein lipase, which causes calories to be sent to fat stores rather than to muscle, Dr. Hedge said.
