Scientists Finally Did a Study to See If Taking 10,000 Steps a Day Actually Matters. Here’s What They Found
You’ve probably heard that taking 10,000 steps daily is good for you.
It makes sense, after all. Exercise is clearly good for your physical and mental health. And 10,000 has a nice, scientific ring to it. But that number of 10,000 had absolutely no research behind it. It was actually dreamed up for a Japanese marketing campaign.
Getting up and moving more is a good idea. But science had no idea if there was a magic number of steps for health or what it might be. So a team out of the University of Massachusetts, Amherst set out to fix that, finally conducting a study to determine how many steps you should really aim for.
Their research followed 2,110 middle-aged adults who had worn a step-counting fitness device beginning in 2005 or 2006 for 11 years. Were those who managed 10,000 steps a day less likely to meet an untimely end, or did some other number seem to matter more?
The researchers determined, as expected that getting more exercise is good. Six thousand steps beats 5,000, and 5,000 beats 4,000 for health outcomes. But they didn’t find anything particularly special about 10,000 steps (except going much beyond it brought no additional health benefits at all).
Instead, 7,000 steps seemed to be an important inflection point. Taking that many steps reduced participants' chances of premature death by 50 to 70 per cent.
That doesn't mean that there's no reason to walk more. The more you move, the more calories you burn, so if your goal is losing weight, longer walks are likely to be more effective. And on the cognitive side, a huge amount of research shows that walking can help improve your creativity and may even help keep your brain young. Plus, it's a big, beautiful world out there. On your feet is a great way to explore it.
But if your aim is simply to stay healthy and reduce your chances of an untimely end, this study shows there's nothing magical about the number 10,000. If your fitness device says you managed fewer steps than that one day, don't feel you have to trudge around the block in the dark until you hit your target. When it comes to maintaining health, 7,000 steps will do just fine.
