Ten thousand steps a day has become a universal benchmark. But it didn’t come from research: it’s widely traced to a Japanese pedometer launched in the 1960s called manpo-kei, which translates as “10,000-step meter.”
What the studies show
A 2019 study in JAMA Internal Medicine followed around 16,000 older women (average age 72). Women who walked about 4,400 steps a day had significantly lower mortality than those who walked about 2,700. The benefit increased with more steps but levelled off at around 7,500 steps a day.
A 2022 meta-analysis in The Lancet Public Health, pooling data from about 47,000 adults, found a similar pattern: risk of death fell progressively with more steps, levelling off at around 6,000–8,000 steps for adults over 60 and 8,000–10,000 for younger adults.
Does pace matter?
The evidence on step intensity is less consistent once total steps are accounted for. Brisk walking does bring additional fitness benefits, so including some faster walking makes sense.
What this means for you
- Every step counts, especially if you’re starting low. Going from 3,000 to 5,000 steps is a meaningful change.
- You don’t need to hit 10,000 for substantial health benefits — 7,000–8,000 is a reasonable target for many women.
- Steps aren’t everything. Walking doesn’t replace strength training for muscle and bone.
The best target is the one you’ll actually keep. Short walks after meals, a walking meeting, or getting off the bus a stop early all add up.
