It should be a fairly common sense acknowledgement that walking more is good for your overall health. So the flip side of that notion being true shouldn't really come as a surprise either; sitting around all day can kill you (more or less)...
"Those who were sitting more were substantially more likely to die," Blair says.NPR has the rundown on the research and some tips for moving around more (from a year and a half ago no less).
Specifically, he found that men who reported more than 23 hours a week of sedentary activity had a 64 percent greater risk of dying from heart disease than those who reported less than 11 hours a week of sedentary activity. And many of these men routinely exercised. Blair says scientists are just beginning to learn about the risks of a mostly sedentary day.
"If you're sitting, your muscles are not contracting, perhaps except to type. But the big muscles, like in your legs and back, are sitting there pretty quietly," Blair says. And because the major muscles aren't moving, metabolism slows down.
"We're finding that people who sit more have less desirable levels" of cholesterol, blood sugar, triglycerides and even waist size, he says, which increases the risk of diabetes, heart disease and a number of health problems.
It isn't that hard to walk a little more each day; take the stairs instead of the elevator, park a little farther away, get off the bus a stop early, go out for a spin around the block at lunch or in the afternoon, walk over to your co-workers' desks instead of calling them, and so on and so forth.
Basically just do what the man says...
