You know that medical advice that you have to walk 10,000 steps a day for maximum health?
Well, you can relax. Turns out, it’s a myth.
A team of researchers from Harvard and other leading institutions just uncovered the medical “source” of this alleged scientific wisdom. And it came neither from a doctor nor a medical establishment, nor even some cutting-edge research.
Instead, it came from the marketing department … of a Japanese clock company. Fifty years ago.
‘Limited scientific basis’
“This number has limited scientific basis,” the researchers said. “There is limited information on how many daily steps are needed for health.”
Or, more elaborately: “An expert committee recently identified a critical gap in knowledge on the dose-response association of steps with health outcomes.”
Translation: We don’t actually know how many steps you should walk every day. Oh, and we don’t know if it makes a difference if you walk them fast or slow either.
So much for expert advice. Another golden nugget of scientific wisdom bites the dust.
