The figure started as a pedometer's brand name in 1965. A 2025 review of 57 studies puts the useful threshold lower, with one catch for anyone under 60.
The number has no study behind it. In 1965 a Japanese company released a pedometer called the manpo-kei, which translates to "ten thousand step meter". The figure was picked for the product, and it has been quoted as a health target ever since.
The research has now caught up.
What 57 studies found
A 2025 review in The Lancet Public Health pooled 57 studies across 35 cohorts, measuring daily steps against eight separate health outcomes (Ding et al., Lancet Public Health, 2025). Compared with 2,000 steps a day, 7,000 steps a day was associated with:
47% lower risk of death from any cause
38% lower risk of dementia
28% fewer falls
25% lower risk of cardiovascular disease
22% fewer depressive symptoms
For several of those outcomes the curve starts to flatten somewhere between 5,000 and 7,000 steps. Past that point the gains keep coming, but they get smaller.
The plateau moves with age
An earlier meta-analysis of 15 cohorts and 47,471 adults found the point where the benefit levels off depends on how old you are (Paluch et al., Lancet Public Health, 2022). In people over 60, risk levelled off around 6,000 to 8,000 steps a day. In people under 60, it kept improving out to 8,000 to 10,000.
So for a working professional in their thirties, forties or fifties, 7,000 is where the largest gains have already been banked. The benefit keeps going past it.
How much to trust it
This is observational data. People who walk more differ from people who walk less in ways no statistical adjustment fully removes, and the authors say so. What gives it weight is consistency. The direction of the finding holds across dozens of cohorts on several continents.
Where steps fit
Walking won't build much muscle or load bone the way lifting does. It is still the cheapest health variable in a week to change. Someone sitting at 3,000 steps a day will get more from reaching 7,000 than from any adjustment to their training program.
Check what your phone says you walked yesterday. That is your baseline.
