1 Many people use their phones to count their steps. Their daily aim is 10,000 steps. Yet the con⁃ cept of taking 10, 000 steps a day to keep fit is rooted not in science but in a marketing trick. In the 1960s, a company in Japan invented a pedom⁃ eter (计步器). Because the Japanese character for 10,000 looks like a person walking, the company called its device the 10,000⁃step meter.

2 “If you get 10,000 steps, it seems like a good goal. But there wasn??t really any basis for it,”says I⁃Min Lee, an epidemiologist (流行病学家) at Harvard Medical School. The current physical activity guidelines from the US Department of Health and Human Ser⁃ vices, published in 2018, are still based on time.

3 The experts recommended broad exercise ranges rather than step counts: 150 to 300 minutes of weekly moderate activity (for example, quick walking) or 75 to 150 minutes of vigorous activity (for example, jogging) during the same period. There simply wasn??t enough evidence to make a similar determination of steps.

4 Now evidence of steps is starting to come in. In 2019, Lee published one of the first studies specifically investigating the actual effects of meeting the 10,000?step goal. Several other large studies followed. The result is that some movement is good, and more is better, but the benefits taper at some point. Your personal peak depends on your age. People younger than 60 should indeed walk 8,000 to 10,000 steps a day to get the best benefits in terms of the lifespan and heart health. People older than 60 show the most benefit between 6,000 and 8,000 steps.

5 Lee says,“Per step, older people expend more energy. As a result, they need fewer steps to achieve the same benefits. But adding a few thousand steps a day can beespecially meaningful for someone who isn??t physically able to walk quickly.”She con⁃ cludes that people who are the least active have the most to gain.
