懷孕時(shí),肚子里的寶寶幾乎所有的時(shí)間都在睡覺
Sleep is the single most effective thing you can do to reset the health of your brain and body. This is true for adults, teenagers and children alike.
睡覺是重置大腦和身體健康的最有效方法。對(duì)于成年人來(lái)說(shuō)如此，對(duì)于青少年和兒童來(lái)說(shuō)也是如此。
Yet, we do not start sleeping when we are born. We actually start sleeping many months before that. Often, through speech or song, expecting parents will thrill at their ability to elicit small kicks and movements from their in-utero child.
但我們并不是出生的時(shí)候才開始睡覺。事實(shí)上，早在出生前幾個(gè)月我們就開始睡覺了。通常，父母希望通過(guò)說(shuō)話或音樂(lè)激發(fā)子宮內(nèi)的寶寶踢一踢或動(dòng)一動(dòng)。
Though you should never tell them this, the baby is most likely fast asleep. Prior to birth, a human infant will spend almost all of its time in a sleep-like state, much of which resembles a stage called rapid eye movement sleep, or REM sleep. The sleeping fetus is therefore unaware of its parents' performative machinations.
雖然你永遠(yuǎn)都不該告訴他們，但子宮內(nèi)的寶寶很有可能睡的很熟。出生之前，嬰兒幾乎所有時(shí)刻都處于睡眠狀態(tài)，其中大部分過(guò)程與淺睡眠階段相似。因此，正在睡眠狀態(tài)中的寶寶根本就不知道父母的表演意圖。
Any co-occurring arm flicks and leg bops that the mother feels from her baby are most likely to be the consequence of random bursts of brain activity that typify REM sleep. Adults do not-or at least should not-throw out similar nighttime kicks and movements, since they are held back by the body-paralyzing mechanism of REM sleep.
母親感受到的寶寶的任何動(dòng)作（胳膊動(dòng)了或腿動(dòng)了）都很有可能是淺睡眠階段大腦活動(dòng)隨機(jī)爆發(fā)的結(jié)果。成年人不會(huì)--至少說(shuō)不應(yīng)該--在夜里有類似的踢動(dòng)或動(dòng)作，因?yàn)檫@些動(dòng)作被淺睡眠時(shí)的身體癱瘓機(jī)制制止了。
But in utero, the immature fetus's brain has yet to construct the REM-sleep muscle-inhibiting system adults have in place. Other deep centres of the fetus brain have, however, already been glued in place, including those that generate sleep.
但在子宮內(nèi)，嬰兒大腦還未成熟，不能構(gòu)筑成年人已有的淺睡眠階段肌肉抑制體系。然而，嬰兒大腦擁有的其它深層中心已經(jīng)就位，包括觸發(fā)睡眠的中心。
As a result of this mismatch, the fetus brain still generates formidable movement commands during REM sleep, except there is no paralysis to hold them back. Without restraint, those activity signals are freely translated into frenetic body movements, felt by the mother as acrobatic kicks and featherweight punches.
由于這種搭配不當(dāng)，嬰兒的大腦仍會(huì)在淺睡眠階段發(fā)布強(qiáng)大的運(yùn)動(dòng)指令，但是卻沒(méi)有癱瘓系統(tǒng)抑制這些動(dòng)作。沒(méi)有了限制，這些活動(dòng)信號(hào)可以自由的轉(zhuǎn)化為狂熱的身體運(yùn)動(dòng)，而母親則將其視作孩子雜技般的踢動(dòng)和"綿綿拳"。
At this stage of in-utero development, most of the time is spent in sleep, split between REM sleep and deep sleep, also called non-REM sleep.
在子宮內(nèi)發(fā)展的階段，嬰兒大多數(shù)時(shí)間都在睡覺，分為淺睡眠和深度睡眠。
It is only when the fetus enters the final trimester that the glimmers of real wakefulness emerge. Far less than you would probably imagine, though-just two to three hours of each day are spent awake in the womb.
只有在最后三個(gè)月，清醒才會(huì)微露光芒。但比你想象的少多了--每天在子宮內(nèi)只會(huì)醒2至3個(gè)小時(shí)。
