More steps meant a lower risk of premature death — but only up to a point, and the point depends on your age. In a 2022 Lancet Public Health meta-analysis of 15 international cohorts (47,471 adults, average age 65, followed for about seven years), the risk of premature death for adults 60 and older levelled off at roughly 6,000-8,000 steps a day, while adults under 60 levelled off at about 8,000-10,000 steps. Going past those ranges was not associated with further benefit. Compared with the lowest-step group (about 3,500 steps a day), the three more active groups had 40-53% lower risk of death. The familiar 10,000-step target is not a scientific threshold: it grew out of a decades-old marketing campaign for a Japanese pedometer.
Where the 10,000-step goal came from
The 10,000-steps-a-day target is one of the most repeated numbers in consumer health, and it did not come from a study. Researchers behind the 2022 analysis trace it to a marketing campaign for a Japanese pedometer decades ago. Their work set out to test what the evidence actually supports.
That matters for how you read your own number. If 10,000 is treated as a pass/fail line, someone walking 7,000-8,000 steps — well inside the range where most of the benefit appears — may conclude they are failing a target that was never evidence-based.
What 47,471 adults showed
Paluch and colleagues harmonised data from 15 cohort studies across four continents covering adults aged 18 and older. Participants were grouped by their average daily step count:
| Group | Average steps/day | Finding |
|---|---|---|
| Lowest quartile | about 3,500 | Reference group |
| Second quartile | about 5,800 | Lower risk of death |
| Third quartile | about 7,800 | Lower risk of death |
| Highest quartile | about 10,900 | Lower risk of death |
Across the three more active quartiles, the risk of death was 40-53% lower than in the lowest group, and risk fell progressively with each higher quartile before flattening. The flattening happened at different step counts by age: about 6,000-8,000 steps for adults 60 and older, and about 8,000-10,000 steps for adults under 60. More steps than that were not linked to further gains in longevity.

An earlier study, in middle-aged adults
A related 2021 analysis in JAMA Network Open followed 2,110 middle-aged adults (aged 38-50 at the start) from the CARDIA study for about a decade. Those averaging at least 7,000 steps a day had a 50-70% lower risk of premature death than those below that level, and walking beyond 10,000 steps did not reduce risk further. Both studies point the same way: most of the benefit appears well below 10,000 steps.
Does walking speed matter?
In the 2022 meta-analysis, researchers did not find a clear association between walking pace and lower risk once total daily steps were accounted for. Getting the steps in, at whatever pace, was what tracked with lower risk. That is useful when building a habit: a slow walk you actually take counts.
Steps versus minutes
US guidance is written in minutes rather than steps: the Physical Activity Guidelines for Americans (2018) recommend at least 150 minutes of moderate-intensity aerobic activity per week for adults. Steps are simply a convenient way to see whether that movement is accumulating. The two targets do not replace each other, and the largest relative gains appear for people currently doing the least — moving a little more than you do now is where the evidence is strongest.
