太空站宇航员谈睡眠问题

◆TRANSCRIPT
Do you think getting a good night sleep is tough? Try doing it in outer space.
A lot of kids asked like, how do you sleep? Because we go around Earth 16 times a day. And so…
You know, what do you wake up?
That's 16 sunsets. Or get up or get down 16 times? I said, no, no.
So, the astronauts go around the earth every 90 minutes, far too fast for the body clock to adapt to, and so, they essentially experience a perpetual jet lag.
But you don't have to be an astronaut to throw your biological clock out of sync.
Virtually every shift work on Earth experiences the same sleep issues.
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.
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.
