英文:

If you have trouble falling asleep that quickly, the studies found that you can still benefit from the coffee nap. Even just drinking the caffeine and getting a few minutes of restful half-sleep half-awakeness is going to make you feel more alert when you do get up 20 minutes later.

如果你很難迅速入睡，研究顯示你還是可以從咖啡覺獲得好處，即使只是攝取咖啡因然後休息幾分鐘、半睡半醒，二十分鐘起來後也會讓你更為清醒。
