Researchers analysed 17 studies that looked at how many steps people took, typically in a weeklong period, and followed up on their health outcomes after around seven years. They concluded that a habit of walking just under 4,000 steps per day reduced the risk of dying from any cause, including from cardiovascular disease.
That translates into a 30- to 45-minute walk, or roughly two miles, although it varies from person to person, said Dr. Seth Shay Martin, a cardiologist at Johns Hopkins Medicine and an author of the study. But the more steps you take, the better off you are: Mortality risk decreased by 15 percent with every additional 1,000 steps participants took.
Here's what else researchers found:
◾ Walking about 2,300 steps a day can reduce the risk of dying from cardiovascular disease (disease of the heart and blood vessels).
◾ Increasing the number of steps you walk per day by 1,000 or even 500 steps will lower your chances of death.
◾ It doesn't matter what age someone starts walking daily, the health benefits still exist even if you start at the age of 60, 65, 70 years of age.
