REM睡眠反彈

REM睡眠反彈（英語：REM rebound）是指在經過一段時間睡眠不足後，睡眠階段中快速動眼期（REM）的頻次與時長的增加。當人們在進入REM前醒來，他們會在後續睡眠中更快速地進入REM。^[1]當人們在一段時間內無法完成足夠的REM睡眠時長，取得REM睡眠的壓力增加，於是在後續睡眠中，REM階段所占時間比率增加。^[2]

早期研究者發現REM睡眠階段與夢相關，占據約20%總睡眠時長。因此，有研究者開始設計REM睡眠剝奪實驗，以探究其重要性。在實驗中，每當受試者的腦電圖與眼球運動顯示出進入REM的跡象，他們就會被叫醒並在後續幾分鐘內保持清醒。隨著「睡眠剝奪」次數增加，受試者更頻繁的試圖進入REM睡眠，因此他們被叫醒的頻次也增加。隨著實驗進行，受試者變得易怒、焦慮、飢餓，部分受試者離開了實驗。五晚之後，剩餘的受試者被允許不受干擾進入睡眠，結果顯示其睡眠中REM階段所占比例顯著增加：從正常狀態的平均19.4%增加到了平均26.6%。相比在隨機時間段、相同頻次被叫醒的對照組，被剝奪REM睡眠的實驗組差異顯著。^[3]

REM睡眠反彈表明，對於大腦而言，睡眠各階段都十分重要。在部分海洋哺乳動物，如海豚和海豹中，當一個大腦半球被剝奪REM睡眠，那麼就這有這半球會出現REM睡眠反彈，而另一半球不受影響。^[2]

REM睡眠反彈常出現在服用安眠藥的人群，也可能在睡眠呼吸暫停患者使用CPAP的前幾晚出現。酒精也會影響REM睡眠，它可在前半晚抑制REM，由此在進入睡眠四到五小時後引發REM睡眠反彈。^[4]多數抗抑鬱藥物，例如西酞普蘭和帕羅西汀，也會抑制REM睡眠，因此在停藥後造成REM睡眠反彈。^[5]^[6]
