Walking cuts risk
- A large study found that increasing daily steps is linked to lower risk of death and heart disease, even for very sedentary people. (sciencedaily.com) - The study tracked more than 72,000 participants to reach this conclusion. (sciencedaily.com) - The takeaway reported is that adding steps still provided measurable benefit for long‑term outcomes, regardless of sitting time. (sciencedaily.com)
Walking more each day was linked to lower risks of death and heart disease in a study of more than 72,000 adults, even among people who spent long hours sitting. (sciencedaily.com) The research, led by the University of Sydney’s Charles Perkins Centre and published in the *British Journal of Sports Medicine*, found the biggest gains at about 9,000 to 10,000 steps a day. At that range, mortality risk was nearly 40% lower and cardiovascular disease risk was more than 20% lower. (sydney.edu.au) The study followed participants for an average of 6.9 years and recorded 1,633 deaths and 6,190 cardiovascular disease events. Researchers said about half of the benefit was reached at roughly 4,000 to 4,500 steps a day. (bmj.com) Step-count studies use a simple measure: how many times a person moves enough in a day for a wearable device to register a step. In this study, the researchers compared those totals with time spent sedentary, meaning waking hours with very little movement, such as desk work or television watching. (bmj.com) The paper adds to a growing body of evidence that the “10,000 steps” target is not a medical cutoff but a rough benchmark. A 2025 review in *The Lancet Public Health* found benefits across several health outcomes at lower step counts too, including around 7,000 steps a day for many measures. (thelancet.com) The new findings do not prove that steps alone caused the lower risks, because the study was observational rather than a randomized trial. The authors adjusted for other factors, but they said the results show association, not cause and effect. (bmjgroup.com) The results also do not mean sitting no longer matters. A separate 2026 study in *Nature Communications*, using Fitbit data from the All of Us Research Program, found that more steps could offset some harms of sedentary time but could not fully erase risk for coronary artery disease or heart failure. (nature.com) The practical message from both studies is narrower than the slogan: more movement helps, and some benefit shows up well before 10,000 steps. For people with desk-heavy days, the evidence points to adding steps where possible rather than treating long sitting as all-or-nothing. (sydney.edu.au)
