A landmark study published in The Lancet Public Health Journal has settled the long-running debate over the optimal number of daily steps, revealing that 7,000 steps per day—not 10,000—is the target for substantial health benefits. The research, which analyzed data from over 160,000 participants across 32 studies, found that achieving 7,000 steps daily is linked to a significantly lower risk of several major health conditions, including dementia, heart disease, diabetes, and cancer.
Key Health Benefits at 7,000 Steps
The study quantified the impact: a 6% reduction in cancer risk, a 38% decline in dementia risk, and a 28% lower risk of falls—which can be fatal for elderly individuals. Dr. Daniel Bailey, a reader in sedentary behaviour and health at Brunel University of London, who was not involved in the study, stated that the findings "debunk the myth that 10,000 steps per day should be the target for optimal health."
Even Modest Increases Help
Researchers observed that even modest step counts of around 4,000 steps per day led to better health outcomes compared to very sedentary lifestyles, where individuals averaged about half that number. For people with conditions such as heart disease, walking more consistently yielded better results. However, the benefits appeared to plateau after approximately 7,000 steps for most health outcomes.
Dr. Bailey added: "The real-world implications are that people can get health benefits just from small increases in physical activity, such as doing an extra 1,000 steps per day."
Study Limitations and Encouraging Findings
The report acknowledges some limitations: the findings on cancer and dementia are based on fewer studies, and some included studies did not fully account for factors like age or frailty. Nonetheless, the researchers emphasize that the 7,000-step target is a more realistic and achievable goal than the widely promoted 10,000 steps, especially for those who are not very active.
Steve Harridge, a professor of human and applied physiology at King's College London, who was not involved with the study, welcomed the research. He said: "This study adds to the body of knowledge that shows physical activity is vitally important for health, and anything that encourages people to be more active is a good thing for both physical and mental health."
