What changes

Moving from sedentary baselines toward 7–10k daily steps is commonly associated with a 20–50% relative reduction in mortality hazard in observational meta-analyses.

When this tends to work

  • Conditions similar to: Adults 40+, longitudinal cohorts and wearables, 2019–2025
  • You can measure All-cause mortality hazard reliably
  • The intervention is implemented consistently, not half-measured

When to be careful

  • Your audience or product differs materially from the cited context
  • Compliance costs or second-order effects outweigh the lift
  • Evidence label is meta_analysis—treat wide ranges as planning bands, not promises

Practical takeaway

Use the cited range for prioritization and test design. Verify against your own data before scaling.
