Beyond the active tactile and muscle signals we were able to study, evidence suggests that the CN receives many more “dormant” inputs that may be important in recovery from neurological injury.
1.tactile: connected with the sense of touch; using your sense of touch
2.dormant: not active or growing now but able to become active or to grow in the future
Fitness tracking devices often recommend we take 10,000 steps a day. But the goal of taking 10,000 steps, which many of us believe is rooted in science, in factrests oncoincidence and sticky history rather than research.
According to Dr. I-Min Lee, a professor of epidemiology at the Harvard T.H. Chan School of Public Health and an expert on step counts and health, the 10,000-steps target became popular in Japan in the 1960s. A clock maker, hoping to capitalize on interest in fitness after the 1964 Tokyo Olympic Games, mass-produced apedometerwith a name that, when written in Japanese characters, resembled a walking man. It also translated as “10,000-steps meter,” creating a walking aim that, through the decades, somehow became embedded in our global consciousness — and fitness trackers.
But today’s best science suggests we do not need to take 10,000 steps a day, which is about five miles,for the sake ofour health or longevity. A 2019 study by Dr. Lee and her colleagues found that women in their 70s who managed as few as 4,400 steps a day reduced their risk ofprematuredeath by about 40 percent, compared to women completing 2,700 or fewer steps a day. The risks for early death continued to drop among the women walking more than 5,000 steps a day, but benefits plateaued at about 7,500 daily steps. In other words, older women who completed fewer than half of the mythic 10,000 daily steps tended to live substantially longer than those who covered even less ground.
Another, more expansive study last year of almost 5,000 middle-aged men and women of various ethnicities likewise found that 10,000 steps a day are not a requirement for longevity. In that study, people who walked for about 8,000 steps a day were half as likely to die prematurely from heart disease or any other cause as those who accumulated 4,000 steps a day. The statistical benefits of additional steps were slight, meaning it did not hurt people toamassmore daily steps, up to and beyond the 10,000-steps mark. But the extra steps did not provide much additional protection against dying young, either.
Realistically, few of us reach that 10,000-step goal, anyway. According to recent estimates, most adults in America, Canada and other Western nations average fewer than 5,000 steps a day.
