The Science Behind 10,000 Steps a Day: How Walking Can Reduce the Risk of Mortality and Cardiovascular Accidents

“The exact origins of the belief that people should aim for 10,000 steps a day is unclear,” writes The New Scientist magazine. “But it is probably linked to a marketing campaign promoting pedometers in Japan. »

Which seems to have worked since, since then, the “10,000 steps” bar has entered our subconscious in the same way as “5 fruits and vegetables a day”.

But is this scientifically verified? Researchers from the University of Sydney have just validated this idea. By sifting through data from more than 72,000 people, researchers observed that from 2,200 daily steps, the risk of mortality is reduced.

Compensate for a sedentary lifestyle

But above all, they found that reaching 9,000 to 10,000 steps per day reduces the risk of premature death or cardiovascular accident by 39%. And that these benefits could counteract the health consequences of too much daily sedentary lifestyle.

For Dr Matthew Ahmadi, lead author of this work, “this is by no means a get-out-of-jail-free card for people who are sedentary for excessive periods of time. However, it contains an important public health message that all movement counts and that people can and should try to offset the health consequences of unavoidable sedentary time by increasing their daily step counts. »
