You become forgetful 变得健忘

Another effect of sleep deprivation is an inability to retain memories. "Insufficient sleep interferes with your ability to focus and learn efficiently, which is essential for you to remember something," Dr. Shane says.

睡眠被剥夺还会影响记忆力，没睡够能够让你很难专心有效的学习，对于你记忆某事产生严峻考验。

"Research shows that sleep strengthens nerve connections involved in memory, and also helps consolidate new information into memories. Insufficient sleep interferes with this." Michael J. Breus, PhD, a clinical psychologist known as "The Sleep Doctor," explains that you need enough REM (rapid eye movement) sleep in order for your brain to solidify memories. "

“研究表明，睡眠能够强化神经之间的链接，这点和记忆相关，所以睡眠有助于强化记住新知识，所以睡眠不足就会记不住。被誉为“睡眠医生”的临床心理学家Michael J. Breus博士解释道，你需要睡眠过程中的快速动眼期来让你的大脑强化记忆。”

You get irritable 你会变得暴躁易怒

You've probably noticed that you wake up "on the wrong side of the bed" if you haven't gotten enough shut-eye. "Sleep deprivation affects mood," Breus says. "It makes you see everything in a more negative light because your emotions are far more volatile when sleep deprived."

如果你没有睡好，那么很有可能发现自己在床的另一头醒来。Breus说：“睡眠被剥夺会影响心情，让你情绪波动大从而只看到事物的负面。”
