The recently released study, Daily steps, and all-cause mortality: a meta-analysis of 15 international cohorts, (1) supports the benefits of walking by linking it to mortality risk.
- For people over the age of 60, increasing daily steps from 3,000 to 7,000 reduces mortality risk by 50%
- For adults under the age of 60, the optimum daily steps appear to be 8,000 to 10,000
Japan’s relatively good daily steps of 6,010, (2) the highest amongst G7 countries, is still low relative to the optimum levels noted above.
