Based on Harvard Health
Are you worried if you can’t complete 10,000 steps at the end of the day? Then we have good news for you.
Or if you don’t like to walk much, then this news will motivate you…
Harvard University has conducted a study by using more than 4500 age 40 and above people. They have supplied accelerometers for all the participants to wear and they monitored their daily step count through the accelerometer for a week.
From the result, they have found out that compared to people who walked 4000 steps, those who walked 8000 steps daily were about half as likely to die for any reason and especially from heart disease. People who took 12,000 steps per day had an even lower risk of dying from heart disease than those who did 8,000 daily. Regardless of their age, sex, or race, the more steps they took, the lower their risk of dying over the following 10 years.
Assistant professor of physical medicine and rehabilitation at Harvard Medical School Dr. Edward Phillips says “Most people typically get around 3,000 to 4,000 steps per day without doing any intentional exercise. That includes things such as doing household chores, checking your mailbox, or going grocery shopping, for example. But if you regularly walk another 4,000 steps a day to reach a total of about 8,000 steps per day, there’s a dramatic difference in whether you live or die over the next decade.”
Another finding of this study was, walking speed has not made any difference in mortality and walking distance has most mattered.
Now the other question is why they constantly talk about 10,000 steps.
The reason is more commercialized rather than scientific. According to the Harvard article, in 1965, a Japanese business, the Yamasa Clock and Instrument Company, sold a pedometer called Manpo-kei, which means, “10,000 steps meter” in Japanese and the company chose that number because the Japanese character for 10,000 looks like a person walking.
There was another study conducted by associate epidemiologist at Brigham and Women’s Hospital, a professor of medicine at Harvard Medical School, and a researcher on physical activity Dr. I-Min Lee with 16,741 women ages 62 to 101 (average age 72). to find out the basis for 10,000 steps and its validity. Their new study in JAMA Internal Medicine answers two questions about mortality: How many steps a day are associated with lowering the mortality rate? Does stepping intensity level make a difference in mortality when people take the same number of steps?
Few of the key findings from the study are,
Sedentary women averaged 2,700 steps a day.
Women who averaged 4,400 daily steps had a 41% reduction in mortality.
Mortality rates progressively improved before leveling off at approximately 7,500 steps per day.
There were about nine fewer deaths per 1,000 person-years in the most active group compared with the least active group.
Both studies have confirmed that the more you walk, you can lesser your mortality.
