8. Don’t go to bed until you’re sleepy.
If you go to bed when you’re just tired, you probably won’t be able to fall asleep, Krakow says. “Distinguish between the feeling of sleepiness and being tired. Get into bed when you’re sleepy -- eyes droopy, you’re drowsy, you feel like you’re nodding off. It’s a very different kind of feeling.”
8、如果你沒有睡意,不要上床睡覺
克拉科夫說:如果當你感覺僅僅有點累的時候就上床睡覺的話,你很有可能不能入睡。要區(qū)分困倦和疲倦有不同感覺。當你感覺困倦的時候再上床睡覺——眼睛是沒有精神的,你也會感到昏昏欲睡的,你會感到你好像在打盹似的。那是一種完全不同的感受。
