Daily Step Recommendations Revised
Recent research indicates walking 7,000 steps each day may significantly enhance brain function and lower the risk of various diseases. This new target seems more achievable compared to the often-cited goal of 10,000 steps.
Published in The Lancet Public Health, the study connects this number to a decreased likelihood of serious health problems, including cancer, dementia, and heart disease. The researchers hope these results could motivate more individuals to monitor their step count as a straightforward health improvement method.
Lead author Dr. Melody Ding pointed out that the 10,000-step goal lacks a solid evidence base. It actually originates from a 1960s marketing strategy in Japan. Before the 1964 Tokyo Olympics, a pedometer brand advertised itself as the “10,000-step meter,” and since then, this figure has been widely accepted, even if it’s not grounded in scientific research.
The study analyzed past research involving over 160,000 adults globally. Findings revealed that those who took 7,000 steps daily experienced notable reductions in various health risks compared to individuals who only walked 2,000 steps. Specifically, there were decreases of:
- 25% for cardiovascular disease
- 6% for cancer
- 38% for dementia
- 22% for depression
However, researchers cautioned that some of these figures might be less reliable, as they stem from a limited set of studies. Still, the review indicates that even stepping around 4,000 times each day can lead to health benefits compared to maintaining a very low activity level of just 2,000 steps. While many health advantages level out after reaching 7,000 steps, going further appears particularly beneficial for heart health.
Current exercise advice typically emphasizes the amount of time spent on activities rather than a specific number of steps. For instance, the World Health Organization recommends adults engage in at least 150 minutes of moderate or 75 minutes of vigorous aerobic activity weekly. Dr. Ding mentioned that some people might find this guidance confusing, but it still plays an essential role. She noted that those who swim, cycle, or have disabilities limiting their mobility might not easily relate to the step count.
Dr. Daniel Bailey, an expert in sedentary behavior and health from Brunel University London, pointed out that this study contests the idea that 10,000 steps are imperative. While this goal might fit well for more active individuals, he believes aiming for 5,000 to 7,000 steps could be more practical for the rest. Meanwhile, Dr. Andrew Scott, a senior lecturer in clinical exercise physiology at the University of Portsmouth, concurred that the precise number isn’t crucial. In his view, “more is always better,” and it’s important not to stress over hitting a specific target, especially during less active days.
