One hour of physical activity daily may offset the risk of sitting at work.
About an hour of moderate-intensity activity (i.e. brisk walking) can erase the increased death rate associated with sitting at work all day. More than 1 million men and women were included in a meta-analysis which found when the least active participants (5 min. per day of moderate activity) sat all day their death rate increased by 27% compared to those sitting less than 4 hours daily. Yet, among the most active individuals (60-75 minutes of daily activity) prolonged sitting was not associated with increased death rates.
PositiveTip: If your job requires sitting all day, be sure to get at least one hour of moderate intensity activity daily.
Physical activity has been engineered out of our lives today!
In the U.S. and the U.K. 70-95% of adults are inactive. Office workers should move around or stand for at least 4 hours during the workday for reductions in heart disease, diabetes and all-cause mortality risks. A Canadian study found significant reductions in risk for cardiovascular mortality in those who stood more than two hours per day, with the greatest benefit in those who stood 4 or more hours daily.
PositiveTip: For your health, make your goal to "move it, move it, move it"!
U.K. experts advise sedentary workers should get up and move throughout the day.
A consensus statement of U.K. public health experts recommends those with desk-based jobs seek to get 2 hours of standing or light activity each workday. The authors cite evidence which links cardiovascular, musculoskeletal, mental health problems, and mortality with sedentary behaviors. They advise sedentary workers to regularly alternate between standing-based and sitting-based work, and strongly recommend adjustable standing desks.
PositiveTip: If you are a sedentary worker, you may experience better health and greater productivity if you mix sitting with standing.
Exercise will not undo the harm of sitting all day!
Sitting can be fatal! Researchers in Germany did a meta-analysis of 43 observational studies that included more than 4 million people. They found sitting is associated with a 24% increased risk of colon cancer, 32% increased risk of endometrial cancer, and a 21% increased risk of lung cancer. The bad news from this study is you cannot exercise away sitting's harmful effects. When adjustments were made for physical activity it did not erase the impact of sitting.
PositiveTip: Keep moving regularly all day long!
