I then said once we're adults, we become monophasic.

然后我说，旦我们成年，就变成了单相睡眠。

And the technical term for this is " monophasic sleep." In other words, a single bout of sleep at night.

这个专业的术语是“单相睡眠”。换句话说，就是在晚性睡眠。

Okay, so getting back to these different phase opportunities for sleep, clearly I'm getting the language wrong here, but monophasic.

好的， 回到这些不同阶段的睡眠机会，显然我在这里用词不当，但说的是单相睡眠。

Well, that brings us to the conclusion of yet another incredible voyage into the landscape of sleep, most notably the different phases, monophasic, biphasic, and polyphasic sleep, and naps, and caffeine, and all of their interactions.

好吧，这我们结束了又关于睡眠领域的奇妙之旅，特别是单相睡眠、两相睡眠多相睡眠，以及小憩因，以及它们之间的相互作用。

So that's how sleep unfolds both at the first level of the lens, monophasic, biphasic, polyphasic, and then double-clicking how the different stages of sleep unfold and what the reasons are behind that.

因此，睡眠在第个层面的分类是单相、两相多相睡眠，然后进步探讨不同睡眠阶段是如何展开的以及背后的原因。

At that point, you have locked in your monophasic pattern, and that will continue throughout adulthood and into old age, with a few caveats that we'll speak about.

到了那步， 你就固定了单相睡眠模式，这种模式会直持续到成年乃至老年，不过有些例外情况我们稍后会讨论。

And then probably by the age of starting school, so sort of five or six, now we're starting to see fully monophasic sleep, children sleeping long bouts at night and then being able to sustain wakefulness during the day.

然后大概在开始学的年龄，也就是五岁或六岁左右， 我们现在开始看到完全的单相睡眠，孩子们晚长时间睡眠， 然后白天能够保持清醒。

Why can't you just simply be born and sleep in a monophasic way?

你为什么不能就这么简单地生都以单相睡眠的方式睡觉呢？

For the most part, monophasic is the one that's most prescribed.

大多数情况下，单相型是最常被推荐的。

To be clear in nomenclature, I'm saying monophasic, biphasic, polyphasic, unpack that.

为了明确术语，我说的是单相睡眠、两相睡眠、多相睡眠，解释下这些概念。

So that's how sleep unfolds in the monophasic, biphasic, polyphasic sleep across the lifespan.

因此，这就是单相睡眠、两相睡眠多相睡眠在人生中展开的方式。

Monophasic obviously just simply means a single phase, monophasic.

单相显然只是简单地意味着单阶段，单相。
