生活壓力增大、睡眠已經成為困擾很多人的一件事情。睡到自然醒、睡個回籠覺，儼然已經成為很奢侈的一件事情。今天我們就來盤點一下那些跟睡覺有關的表達。

1. 回籠覺 unprotected sleep

什么叫unprotected sleep？字面上理解是無保護的睡眠或風險睡眠，指的是turning off your alarm clock and immediately going back to sleep; risking not waking up for a job, class, or other daily task. 冒著工作、上班等遲到的風險關掉鬧鐘睡回籠覺，這是不是很多人每天生活的真實寫照？

e.g. I'm lucky that I didn't miss my final exam after having 30 minutes of unprotected sleep.

我真走運，睡了30分鐘的回籠覺還沒錯過期末考試。

2. 自然醒 wake up naturally without alarm clock

有研究表明早上被鬧鐘吵醒容易造成神經衰弱現象，可是試問現在有哪個人早上不是被鬧鐘吵醒的?當然也有鬧鐘吵不醒的筒子們。ditch the alarm clock是需要很大勇氣的！

e.g. The second school says you should listen to your body's needs and go to bed when you're tired and get up when you naturally wake up.

另外一種觀點認為你應該按照你身體的需求，累了之后就睡覺，一覺睡到自然醒。

3. 那些關于“睡覺”的短語：

e.g. After working in the garden all morning, I had a cat nap before lunch.

我在花園里干了一上午的活兒，所以午飯前小睡了一會兒。
