10,000 Steps A Day？How Many You Really Need To Boost Longevity
今天你走够一万步了吗？各种计步软件都提醒我们，每天走一万步有利健康。然而研究人员近日表示，每天要走一万步的想法是荒诞的，每天行走4400步就足以降低早亡的风险。
她说：“对我来说，这项研究表明，轻度活动的好处比我们之前认为的要多。”
Of course, the researchers point out, they would like to know much more about how walking may affect other health parameters such as quality of life and memory and cognitive function. It's possible that walking a greater number of steps each day could influence these outcomes.
当然，研究人员指出，他们想知道更多关于步行如何影响其他健康参数的信息，如生活质量、记忆力和认知功能。每天走更多步可能会影响这些结果。
Another thing Janz notes is that this study only measures walking. It didn't measure things that many of us do that don't require steps, things like gardening, swimming or biking. And it's safe to assume some women in the study were doing these other things that can influence health as well.
扬茨还注意到，这项研究只研究了步行。它没有测量我们很多人做的不需要步行的事情，比如园艺、游泳或骑自行车。可以肯定的是，这项研究中的一些女性也在做这些会影响健康的事情。
And Janz says to remember the federal exercise guidelines call for 150 minutes per week of moderate physical activity, which includes all kinds of daily movement, not just steps.
扬茨说，要记住联邦运动指南要求每周进行150分钟的适度体育活动，包括各种日常运动，而不仅仅是步行。
So, if 10,000 steps has been feeling out of reach to you, it may be time reset those factory settings on your fitness tracker. Instead, try to hit at least 4,400 a day, along with daily activities that you enjoy. And stick to it.
所以，如果你觉得1万步已经遥不可及，那么是时候在你的健身追踪器上重置这些出厂设置了。你可以试着每天至少走4400步，再做些你喜欢的日常活动，并坚持下去。
