Walking 10,000 Steps a Day Debunked: New Study Reveals Optimal Step Count for Women
Scientists have declared the widely promoted goal of walking 10,000 steps daily a myth, with new research indicating that a significantly lower number of steps can provide substantial health benefits for older women. A study published in the British Journal of Sports Medicine found that women who walked just 4,000 steps per day on one or two days a week experienced a 26% lower risk of early death from any cause and a 27% reduced risk of heart disease.
Key Findings from the Research
The study, conducted by researchers including those from Harvard University, involved 13,547 women with an average age of 72 who were free from heart disease and cancer at the start. Participants wore step-counting devices for seven consecutive days and were tracked for nearly 11 years. During this period, 1,765 women (13%) died, and 781 (5.1%) developed heart disease.
The research concluded that the total volume of steps taken is more critical than the frequency of activity. Specifically, achieving 4,000 steps on one to two days weekly led to significant protective effects, while walking this amount on three days a week further reduced the risk of early death by 40% and maintained a 27% lower risk of heart disease.
Challenging Traditional Guidelines
This finding directly challenges the long-held benchmark of 10,000 steps daily, with experts stating there is "no 'better' or 'best' pattern" for gaining health benefits through walking. They emphasized that movement is essential, and "individuals can undertake physical activity in any preferred pattern." The study suggests that physical activity guidelines for older women should be updated to recommend at least 4,000 steps per day on one to two days per week to lower mortality and cardiovascular disease risk effectively.
Additional Benefits and Modest Gains
For those who engaged in more exercise, such as 5,000 to 7,000 steps, the benefits were more modest. This level resulted in a 32% lower risk of death, but the reduction in cardiovascular disease death risk plateaued at 16%. The researchers noted that "the number of steps per day, rather than the frequency of days/week achieving a particular step threshold, is important" for cutting the risk of early death and heart disease in older women.
Overall, the team affirmed that a "greater number of steps, regardless of daily patterns, is associated with better health outcomes," reinforcing the importance of consistent physical activity tailored to individual capabilities and preferences.
