CNN News: 太空站宇航員談睡眠問題

Do you think getting a good night sleep is tough? Try doing it in outer space.
你覺得晚上睡個好覺很難嗎？那你試試在太空睡個覺。
A lot of kids asked like, how do you sleep? Because we go around Earth 16 times a day. And so --
很多孩子會問，你是怎么睡覺的？因為我們每天要繞地球轉16次。所以……
You know, what do you wake up?
你知道，醒來會是什么嗎？
That`s 16 sunsets.
那可是經歷了16次日落
Or get up or get down 16 times? I said, no, no.
那是經歷16次起床、睡覺嗎？我說，不，不是的。
So, the astronauts go around the earth every 90 minutes, far too fast for the body clock to adopt to, and so, they essentially experience a perpetual jet lag.
所以，宇航員每90分鐘繞地球一圈，速度實在太快導致生物鐘無法適應。因此，他們本質上是在經歷一場無期限的時差反應。
But you don`t have to be an astronaut to throw your biological clock out of sync.
不過，即使不成為一個宇航員，你也可以把生物鐘打亂。
Virtually every shift work on Earth experiences the same sleep issues.
事實上，地球上的每一次輪班都經歷著同樣的睡眠問題。
Just like astronauts, you can take simple steps to improve your sleep. Keep a regular sleep schedule. Block out any light. And avoid screen time before bed. Otherwise, your lack of sleep could catch up to you.
就像宇航員一樣，你可以通過采取簡單的步驟來改善睡眠質量。保持規(guī)律的睡眠時間。遮擋住所有光線，并且要在睡前避免看屏幕。否則，睡眠不足會影響到你的生活。
When you`re in space, the stakes are much higher. So, a missed keystroke can be the difference between, you know, life and death really.
當你身處太空時，風險要高得多。所以，任何一次失誤都可能會導致生死之別。
