From The Washington Post:
If you fear you’re doing irreparable damage to your body because your white-collar job keeps you sitting at your desk from 9 to 5, or you regularly spend entire weekends sprawled out on your couch binge-watching Netflix, there’s some good news just out from sports medicine researchers.
According to a study published in The Lancet, all is not lost. You may be able to “make up” for your increased risk of death due to a sedentary lifestyle by engaging in enough physical activity.
So just how much is enough? The first thing you need to know is that it’s not a fixed number but based on a ratio that depends on the amount of sitting you do daily. If you sit four hours a day, you need to do at least 30 minutes of exercise. An eight-hour work day of sitting means one hour of exercise.
The numbers come from an analysis based on a very large pool of people, about 1 million adults, 45 and older, from the United States, Western Europe and Australia. The findings show a risk reduction — or even elimination — for your risk of death from heart disease, diabetes and some cancers.
Researcher Ulf Ekelund, a professor at the Norwegian School of Sports Sciences, suggested that the one hour of activity could be brisk walking or cycling but said that the exercise doesn’t have to be so rigorous or all at one time. That is, the hour of activity can be spread out over the entire day.
. . . .
The findings suggest that the person who sits longer isn’t necessarily worse off: Those who sat for eight hours a day but were physically active were better off in terms of risk of death than those who sat for fewer hours but were not physically active.
