什么事快速眼動(REM)睡眠

Rapid eye movement (REM) sleep is a unique stage of sleep characterized by random rapid movement of the eyes (via Medical News Today). During this phase, your body undergoes a number of physical and neurological changes, including increased brain activity, elevated heart rate, fast and irregular breathing, rapid eye movement, high blood pressure, changes in body temperature, increased oxygen consumption by the brain, sexual arousal, and twitching of the face and limbs.

快速眼動(REM)睡眠是一種獨特的睡眠階段，其特征是眼球的隨機快速運動。在這一階段，你的身體會經(jīng)歷一系列的生理和神經(jīng)變化，包括大腦活動增加、心率加快、呼吸急促和不規(guī)則、眼球快速運動、高血壓、體溫變化、大腦耗氧量增加、性喚起以及臉部和四肢抽搐。

Your first REM cycle occurs around 90 minutes after you fall asleep and usually lasts for 10 minutes. As the night goes on, each REM cycle will get progressively longer and recur every 90 minutes. Since REM sleep is associated with increased brain activity, it is common to experience vivid and intense dreams during this stage of sleep. Because of the intensity of these dreams, your muscles are immobilized to prevent you from acting out your dreams, leaving your limbs temporarily paralyzed. As a result, REM sleep is also sometimes referred to as paradoxical sleep.

第一個快速眼動周期發(fā)生在入睡后90分鐘左右，通常持續(xù)10分鐘。隨著夜晚的繼續(xù)，每個快速眼動周期會逐漸變長，每90分鐘重復一次。由于快速眼動睡眠與大腦活動增加有關，在這個睡眠階段通常會經(jīng)歷生動而強烈的夢境。因為這些夢的強度，你的肌肉被固定住，阻止你執(zhí)行你的夢，使你的四肢暫時癱瘓。因此，快速眼動睡眠有時也被稱為矛盾睡眠。

REM sleep is crucial to your overall health and plays an important role in brain function and development. For instance, REM sleep can impact your memory (via Shape). Studies have shown that REM sleep benefits learning and memory by allowing you to process new memories and maintain essential neural pathways responsible for learning and creating new memories.

快速眼動睡眠對你的整體健康至關重要，對大腦功能和發(fā)育起著重要作用。例如，快速眼動睡眠可以影響你的記憶。研究表明，快速眼動睡眠有利于學習和記憶，因為它能讓你處理新記憶，并保持負責學習和創(chuàng)造新記憶的基本神經(jīng)通路。

During sleep, your brain is sort of replaying certain things you've experienced and trying to figure out if it should put that experience into your short-term or long-term memory-or to just forget about it, Dr. W. Chris Winter, a sleep specialist and neurologist, told Shape. "Unlike deep sleep, which is really concerned with rest and recovery, REM sleep has lots more to do with concentration, focus, memory consolidation, and pain perception."

睡眠專家、神經(jīng)學家w·克里斯·溫特博士在接受《Shape》雜志采訪時表示:“在睡眠中，你的大腦會回放你經(jīng)歷過的某些事情，并試圖弄清楚是應該將那段經(jīng)歷納入短期記憶還是長期記憶，或者干脆忘掉。”“與真正關注休息和恢復的深度睡眠不同，快速眼動睡眠更有助于注意力、注意力集中、記憶鞏固和疼痛感知。”

REM sleep can also impact brain development in infants (Verywell Mind). That's because the increased brain activity that occurs during REM sleep is responsible for developing and strengthening mature neural connections.

快速眼動睡眠也會影響嬰兒的大腦發(fā)育。這是因為快速眼動睡眠期間大腦活動的增加負責發(fā)展和加強成熟的神經(jīng)連接。
