10K Is Great But Less Is OK Too
Let's face it. Ten thousand steps is a lot. Is it really necessary to get to 10,000? How about 9,500? Or 7,500? And where did that number come from anyway?
Professor I-Min Lee, ScD, of the Harvard Medical School led a research project reviewing the 10,000 step goal that many people are using. The study, co-sponsored by the National Institute on Aging (Masamitsu Kamada, PhD, was a participating researcher), found that less than 10K steps can do the job. A group of almost 17,000 women wore pedometers to create a sample of daily steps. Subsequently their health outcomes were tracked for 4+ years. Women who walked 4,400 steps a day were 41% less likely to die than women who walked under 2,700. Benefit seemingly topped out at 7,500 steps a day.
The speed of walking may matter, but the statistics from this study on that were a little murky.
Professor Lee noted: “Our message is not a new message: “Physical activity is good for you. What’s new and striking is how little you need to do to make a difference”. Link to the study here.
More Brain-Building Ideas
I founded Big Brain Place because I saw how fast science is discovering the secrets to brain health, and realized how little I knew about it. Clearly I couldn't be the only one not familiar with the possible actions that can optimize brain health. At BigBrain.Place we are on a mission to help everyone, at any age, improve cognition, reduce the risk of dementia, insure our children have the opportunity to develop maximum brain capacity, and, in general, make our brainspans match our lifespans.
