Short answer: Paluch and colleagues 2022, published in The Lancet Public Health, pooled 15 cohort studies covering nearly 50,000 adults. Mortality risk fell as daily steps rose, but the benefit levelled off around 6,000 to 8,000 steps in adults over 60, and 8,000 to 10,000 in younger adults. There was no additional benefit beyond those plateaus.

What the study did
A meta-analysis of prospective cohort studies in which participants wore accelerometers, rather than self-reporting activity. That distinction matters: device-measured data avoids the substantial recall error that affects questionnaire-based activity research.
Participants were followed for a median of around seven years, with all-cause mortality as the outcome. Analysis was stratified by age, which is what produced the most useful finding.
The findings
| Group | Plateau |
|---|---|
| Adults 60 and over | About 6,000-8,000 steps |
| Adults under 60 | About 8,000-10,000 steps |
- The dose-response curve is steepest at the low end. Moving from roughly 3,000 to 6,000 steps produced a far larger risk reduction than moving from 8,000 to 12,000.
- No harm at high counts, simply no additional mortality benefit.
- Stepping intensity was not independently associated with mortality once total volume was accounted for, which contrasts with some earlier work.
What this corrects
The 10,000 step target has no research origin. It traces to a Japanese pedometer marketed in the 1960s as the manpo-kei, literally the ten thousand step meter. It was a memorable round number, not a finding.
The practical consequence is encouraging: someone walking 4,000 steps daily gains more from reaching 7,000 than someone at 9,000 gains from reaching 13,000. If 10,000 feels unreachable, the evidence says most of the benefit arrives well before it.
The limitation to keep in mind
These are observational cohorts, not randomised trials. People who walk more differ from people who walk less in ways that are difficult to fully adjust for, including baseline health. Reverse causation is a genuine concern: illness reduces walking, rather than only the reverse.
The authors addressed this by excluding early deaths, which strengthens the case without eliminating the issue entirely.
FAQ
How many steps a day should I walk?
Benefits level off around 6,000 to 8,000 for adults over 60 and 8,000 to 10,000 for younger adults, on this evidence.
Is 10,000 steps scientifically based?
No. It originated as a 1960s Japanese pedometer marketing name.
Does walking faster matter?
In this analysis, stepping intensity was not independently associated with mortality once total volume was accounted for.
Is walking more than 10,000 harmful?
No harm was found. There was simply no further mortality benefit.
