It doesn’t matter how much you sit — walking more could lower your risk of death and disease
For years, public health messaging has warned that prolonged sitting is as dangerous as smoking, urging office workers to stand desks and accept frequent breaks. But a large-scale international study now suggests that while sedentary behavior remains a concern, the antidote may be simpler than previously thought: increasing daily steps, regardless of how much time is spent sitting.
Research published in the British Journal of Sports Medicine analyzed data from over 72,000 participants across multiple countries, tracking their physical activity through wearable accelerometers and following them for an average of 6.9 years. The findings indicate that even among individuals who sit for 10 or more hours a day, taking more steps each day is associated with significantly lower risks of premature death and cardiovascular disease.
The study, led by researchers from the University of Sydney and involving collaborators from institutions in Europe and Australia, found that the optimal benefit occurred around 9,000 to 10,500 steps per day. At this level, participants experienced a 39% lower risk of all-cause mortality and a 21% reduced risk of incident cardiovascular disease compared to those taking fewer than 4,000 steps daily. These associations held true across different levels of sitting time, suggesting that step count may be a more powerful predictor of health outcomes than sedentary duration alone.
“Our results show that accumulating steps is beneficial for health, irrespective of how much time is spent sedentary,” said Dr. Matthew Ahmadi, lead author and research fellow at the University of Sydney’s Charles Perkins Centre. “This doesn’t indicate sitting is harmless, but it does suggest that people who sit a lot can still offset some of the risks by moving more throughout the day.”
The research builds on growing evidence that total physical activity volume, particularly walking, plays a central role in metabolic health, inflammation regulation and cardiovascular function. Unlike structured exercise, which requires dedicated time and motivation, increasing step count can be achieved through small, cumulative changes — taking the stairs, walking during phone calls, or parking farther from entrances.
According to the World Health Organization, adults should aim for at least 150 minutes of moderate-intensity aerobic activity per week, which roughly translates to 7,000 to 8,000 steps daily for most individuals. But, the Sydney-led study suggests that exceeding this threshold — particularly reaching 9,000 to 10,500 steps — may offer additional protective benefits, especially for those with high sedentary exposure.
Wearable technology has made tracking steps more accessible than ever. Devices from companies like Fitbit, Apple, and Garmin now provide real-time feedback on daily movement, helping users set and monitor goals. While these tools are not medical devices, their widespread use has enabled large-scale observational studies like this one, offering insights that were challenging to obtain through self-reported questionnaires alone.
Experts caution that the study, while robust, is observational and cannot prove causation. Individuals who take more steps likewise engage in other healthy behaviors — such as better diet, lower stress, or reduced smoking — that contribute to the observed outcomes. However, researchers adjusted for numerous confounding factors, including age, sex, body mass index, smoking status, diet quality, and socioeconomic status, strengthening the validity of the association.
“We can’t say that walking more directly causes lower risk,” explained Professor Emmanuel Stamatakis, senior author and expert in physical activity epidemiology at the University of Sydney. “But the consistency of the findings, the dose-response relationship, and the biological plausibility all point to a meaningful protective effect.”
The study’s authors emphasize that the message is not to encourage prolonged sitting but to empower individuals who, due to work, health, or environmental constraints, may find it difficult to reduce sitting time. For desk workers, caregivers, or those with mobility limitations, focusing on step accumulation offers a flexible and achievable strategy to improve long-term health.
Public health campaigns are beginning to shift from vilifying sitting to promoting movement in all its forms. Initiatives like the UK’s “Active Working” program and Australia’s “Be Up Standing” campaign encourage breaking up sitting time with light activity, reinforcing the idea that every step counts.
As wearable technology continues to evolve and population-level data becomes more granular, researchers hope to refine step-based guidelines further — potentially tailoring recommendations by age, baseline fitness, or chronic disease status. For now, the evidence supports a simple, inclusive message: wherever you are, however much you sit, moving more — especially by increasing your daily steps — is a proven way to protect your health.
The next major update on physical activity guidelines is expected from the World Health Organization in 2025, when it will review the latest evidence on aerobic activity, muscle strengthening, and sedentary behavior. Until then, individuals seeking to improve their health can consult their national public health agencies or speak with a healthcare provider about setting realistic, personalized activity goals.
