During the day, your brain is a beehive of activity—during NREM sleep, it is barely humming.
在白天，你的大脑就像一个活跃的蜂窝——在非快速眼动睡眠期间，它就几乎没有嗡嗡声了。
This occurs because during NREM sleep the automatic, metabolic system has exclusive control over breathing and the body uses less oxygen and produces less carbon dioxide.
这是因为在非快速眼动睡眠中，自动的新陈代谢系统对呼吸有排他的控制，身体消耗更少的氧气，产生更少的二氧化碳。
Think of it this way: in NREM sleep, your brain isn't very active, but your body is.
可以这样来考虑：在NREM状态，大脑平静但身体活跃。
During the day, your brain is a beehive of activity -- during NREM sleep it is barely humming.
白天时，大脑就像一个忙乱的蜂窝——而进入NREM睡眠状态后，它就很少嗡嗡叫了。
NREM sleep is also when your body repairs itself and releases hormones, including growth hormones.
NREM睡眠状态中人的身体同时也在做自我恢复以及分泌激素，包括生长激素。
NREM sleep is when you tend to toss and turn in bed. Your brain quiets down, which means that you aren't dreaming.
NREM睡眠状态是指身体在床上翻来覆去，但大脑趋于平静，意味着没有在做梦。
"NREM sleep is divided into four stages, the last of which is the deep, restorative, quiet sleep commonly associated with" a good night's rest.
NREM睡眠则分为四个阶段，最后一阶段就是我们平常称为“好觉”的最能恢复精力的平静熟睡。
The value of correlation dimension can reflect sleep stages after analyzing and simulating the sleep EEG, and then simulation forecast for NREM sleep stage was made which accorded with actual result.
以长程睡眠脑电数据分析和仿真为例，分析结果表明关联维的高低能够反映出睡眠的阶段，据此对非快速眼动睡眠期的仿真预测与实际结果相符。
Second, once sleep is fully obtained, there is an increase of carbon dioxide and a decrease of oxygen in the blood that persists during NREM.
第二，一旦完全进入睡眠状态，非快速眼动期间血液中的二氧化碳增加，氧气减少。
Additional breathing changes occur during REM sleep that are even more dramatic than the changes that occur during NREM.
在快速眼动睡眠期发生的额外的呼吸变化，甚至比那些在非快速眼动期发生的变化还要显著。
They found that success in learning correlated with the amount of stage-2 non rapid eye movement (NREM) sleep, the stage preceding deep rapid eye movement (REM) sleep.
他们发现学习上的成功和第二阶段非快速眼动（NREM）相关。 NREM是深快速眼动（REM）睡眠之前的阶段。
