For decades, researchers have tried to determine the optimal dose (duration, frequency, intensity, etc.) of daily physical activity that reduces morbidity and increases longevity.

Would it motivate you to walk every day, if we tell you that even 4500 steps a day can have the effect of making you live longer?

Epidemiologists are still not 100% sure about the ideal "dose" of daily physical activity for men and women, at different stages and conditions of life. When it comes to walking, not exercise, there is a standard ingrained in people's minds that they should definitely do 10,000 steps.

However, studies have shown that a walk equal to at least about 4,500 steps - can reduce mortality from all causes. 

"Doing 10,000 steps a day may sound disturbing, impossible or tedious, but we find that even a modest increase in steps is gradually associated with significantly lower mortality," said I-Min Lee, one of the lead authors. of study.

That said, the purpose of the study was for people not to "spread panic" if they do not find the opportunity or time for 10,000 or more steps. However, it remains important and healthy to walk regularly and in one way or another get your body moving. Think of this as a walk, meditation, and time for yourself, even if you are just making your way home from work.
