We are regularly urged to take 10,000 steps a day. However, it turns out 10,000 isn’t exactly a number anchored in science. Rather, it’s a product of marketing. According to a Harvard medical website, that figure goes back to “1965, when a Japanese company made a device named Manpo-kei, which translates to ’10,000 steps meter.’ ” 10,000 likely sounded better than a more precise number. And so it began.
So this raises the question: what’s the ideal number of steps according to science? Dr. I‑Min Lee, a professor of medicine at Harvard Medical School, focused on that question and determined that mortality rates decline when women increase their steps from lower levels (e.g., 2,000 steps) to 4,400 steps per day, with gains increasing until they reach 7,500 steps. From there, the gains level out. (Read the JAMA study here.) Meanwhile, a European study, which monitored 226,000 participants, found that people who walked more than 2,337 steps daily could start lowering their risk of dying from heart disease. And people who walked more than 3,867 steps daily could start reducing their risk of dying from any cause overall. However, unlike the Harvard study, the European study found that adding more steps continues to lower mortality rates, with gains accruing past 7,500 steps, and perhaps beyond 20,000 steps. What’s the exact sweet spot? We’ll need more research to figure that out. Until then, the existing research suggests that it pays to spend time with your walking shoes.
