“Don’t be intimidated or dissuaded by the 10,000 number.”
via Harvard Health Publishing
Many of us have been told that 10,000 steps a day is the target for good health. Fitness trackers celebrate when you reach it. But where does the number come from, and is it really what the evidence recommends?
Ten thousand steps is a perfectly good goal, but the evidence does not show that you need it. In the large studies reviewed here, most of the health benefit appears at lower step counts, with gains flattening out somewhere between roughly 5,000 and 8,000 steps a day. Even a modest increase from a very low baseline is linked to better outcomes.
The number appears to be a marketing legacy rather than a scientific finding. Harvard epidemiologist I-Min Lee traced it back to 1965, when a Japanese company, Yamasa Clock and Instrument Company, sold a pedometer called Manpo-kei, which translates to "10,000-step meter." In her 2019 study, she wrote that the origin is unclear but likely derives from that trade name. She has described the name as a marketing tool.
About Me – Dr. Rajnandini Dubey
Hello, I’m Dr. Rajnandini Dubey, a Physiotherapist with a Master’s degree in Sports Physiotherapy and currently working as an Assistant Professor in the Department of Physiotherapy. Along with my academic career, I have been working as a professional academic and medical writer for the past 3–4 years, contributing to research papers, postgraduate thesis, PhD dissertations, and healthcare websites.
Through The Health Journals, my aim is simple: to provide reliable, evidence-based, and authentic health information that readers can truly trust. In today’s digital world, health information is widely available, but unfortunately, not all of it is accurate or scientifically supported. That is why every piece of content shared here is written with a strong focus on research evidence, clinical knowledge, and academic integrity.
My experience in physiotherapy education, research writing, and healthcare content development allows me to analyze scientific literature and present it in a way that is clear, practical, and useful for students, healthcare professionals, and the general public.
I strongly believe that health education should be based on facts, not misinformation. This platform is dedicated to sharing credible updates, research-based insights, and scientifically validated health knowledge so that readers can make informed decisions about their health and learning.If you are looking for authentic health information backed by scientific understanding, you are in the right place.
Limits: it was an observational study, so it cannot separate whether more steps lower mortality or whether healthier women simply walk more. It looked only at older women and only at mortality, and the researchers noted results could differ in younger or more active people.
A larger synthesis was published in The Lancet Public Health in 2025. The researchers, led from the University of Sydney, reviewed 57 studies from 35 cohorts of adults using device-measured steps, and 31 studies from 24 cohorts fed into the meta-analyses. For all-cause mortality, cardiovascular disease incidence, dementia, and falls, the association was non-linear, with inflection points at around 5,000 to 7,000 steps a day.
Compared with 2,000 steps a day, 7,000 steps a day was associated with:
The association with cancer incidence was small and not statistically significant (6% lower). The authors also found that 4,000 steps a day compared with 2,000 was associated with a 36% lower risk of death from any cause. Their conclusion was that 10,000 steps remains a viable target for people who are more active, but 7,000 steps is linked to clinically meaningful health improvements and may be a more realistic target for some.
These findings come from observational studies, so they show associations, not proof that steps cause the benefit. The Lancet analysis reports moderate certainty for most outcomes but lower certainty for some, including cardiovascular mortality, cancer incidence, physical function, and falls. The authors also point to a small number of studies for most outcomes, a lack of age-specific analysis, and possible residual confounding. People who are healthier may walk more, which is hard to fully remove from the data. The researchers said future studies should look at targets for different age groups.
