2-Minute Bursts of Movement Can Have Big Health Benefits
各位好。
最近咱们国人之间打招呼的方式好像已经从“您吃了没”变成“您🐑了没”。当然与之相配套的是每一次交流的结尾都会奉上一句“注意保重身体，注意强身健体”。
健康从来没有这么重要地被我们提起，也没有这么迫切又实际地需要我们自己来守护。怎么说呢，其实有些道理谁都懂，比如要想身体好，除了要吃得对，而且还要迈开腿。但是顶着这越来越冷的严寒，出门锻炼动辄还要跑个半小时，这需要耗费多大的勇气？更别说这一出门就怕被传染。
吃这方面且不说，咱们今天来聊聊锻炼这个难点。这几天我看《纽约时报》上的这篇文章，倒真是戳中了我们这些不爱锻炼的人的痛点，我就不卖关子了，咱们直奔主题。
A new study confirms that you don't have to do a hard workout to reap the longevity rewards of exercise.
- Those who engaged in one or two-minute bursts of exercise roughly three times a day, like speed-walking while commuting to work or rapidly climbing stairs, showed a nearly 50 percent reduction in cardiovascular mortality risk and a roughly 40 percent reduction in the risk of dying from cancer as well as all causes of mortality, compared with those who did no vigorous spurts of fitness.
- One 2020 study linked four-minute bursts of exercise with longer life spans; another in 2019 found that climbing stairs for 20 seconds, multiple times a day, improved aerobic fitness. And still others have found that repeating just four-second intervals of intense activity could increase strength or counteract the metabolic toll of sitting for long stretches of time.
