If you need an alarm clock to get you out of bed in the morning, if you are taking a long time to get up, if you need lots of stimulants, if you're grumpy, if you're irritable, if you're told by your work colleagues that you're looking tired and irritable, chances are you are sleep-deprived.
如果早上起床你需要一个闹钟， 如果你花很长时间起床， 如果你需要大量的兴奋剂， 如果你脾气乖戾易怒， 如果你的同事告诉你 您看起来疲倦和易怒、 你很可能就是睡眠不足。
