Are you late again?

又遲到了嗎？

Sometimes we wish we never had to deal with this morning struggle.

有時候我們希望可以不用每天早上面對這個掙扎。

But what if you just never went to bed?

但如果都不去睡覺呢？

What if you figured out how to keep yourself awake forever?

如果有方法可以永遠保持清醒呢？

This is "What If," and here's what would happen if you stopped sleeping.

這裡是 What If 節目，以下要來介紹停止睡覺的話會發生什麼事。

How often have you needed just a few more hours to finish a project, get ready for a date, or enjoy your day off?

你需要多花幾個小時完成某項計畫、準備約會或享受假期的頻率有多少？

If you took sleep out of your daily routine, you'd have all 24 hours of the day to do everything you never had time for.

如果把睡眠從日常生活中剔除，就會有一天 24 小時的時間來做從來沒有時間做的事情。

What's a few yawns and some minor tiredness if it meant you never had to waste any more time lying in bed for no good reason?

如果這表示你再也不必無緣無故地躺在床上浪費時間，那麼打幾個哈欠和一些輕微的疲倦算什麼？

Turns out, there are plenty of good reasons to sleep.

事實證明，有很多充分的理由證明需要睡覺。

The average person spends one-third of their life lying in bed, eyes shut, snoring away.

一般人一生中有三分之一的時間躺在床上，閉著眼睛打呼。

Sounds like a waste of valuable time.

聽起來像是在浪費寶貴的時間。

But not for your body.

但對你的身體來說不是。

While you sleep, your body releases hormones and repairs tissues, replacing your old cells with new ones.

當你睡覺時，你的身體會釋放荷爾蒙並修復組織，用新細胞替換舊細胞。

If you worked out that day, you need a good sleep to let your muscles grow and your fat burn.

如果你那天有健身，就會需要一個良好的睡眠來讓你的肌肉生長和讓脂肪燃燒。

So what happens if you don't sleep?

那麼不睡覺會發生什麼呢？

Not much at first.

一開始沒什麼變化。

After just 24 hours, you'd feel completely fine.

剛過 24 小時的時候，你會感覺很好。

In fact, you'd feel better than "fine."

事實上，會比「很好」還要更好。

That's because sleeplessness stimulates the mesolimbic pathway in your brain.

那是因為失眠會刺激大腦中的中腦邊緣通路。

This pathway would release dopamine, and you'd feel happy and full of energy.

這個通路會釋放多巴胺，讓人感到快樂和充滿活力。

But don't be fooled by all that happiness. It's not going to last long.

但是不要被這些幸福感所迷惑，它不會持續很長時間。

Soon after reaching the 24-hour mark, all your reactions would slow down.

到達 24 小時後不久，身體的所有反應都會變慢。

Your brain would start to forget what you were doing.

大腦會開始忘記身體在做什麼。

Outwardly, you'd appear to be drunk.

從表面上看，你看起來像喝醉了。

Wait, where were we?

等等，我們講到哪了？

Right, now what about two days without sleep?

對，那如果兩天沒有睡覺呢？

At that point, your body would start shutting down.

到那時候，身體機能會開始關閉。

It would stop metabolizing glucose properly, leaving you with no energy supply.

它會停止正常代謝葡萄糖，讓你沒有能量供應。

You'd start looking very pale.

你會開始看起來很蒼白。

Your eyes would turn red, and then more bad news: your wrinkles would become more visible.

眼睛會變紅，然後更多壞消息是：你的皺紋會變得更加明顯。

On day three, that's when the real fun begins.

到了第三天，真正的樂趣才要開始。

Starved of REM sleep, your brain would bring all your dreams and nightmares to life.

缺乏快速眼動睡眠，大腦會把你所有的夢想和噩夢都帶到現實生活中。

At around the 72-hour mark, you'd start breaking down your own protein.

到了 72 小時，你會開始分解自身的蛋白質。

So say goodbye to all that muscle mass you worked so hard to build up.

跟你辛辛苦苦建立起來的所有肌肉說再見吧。

Your body would keep using up all the energy sources it could find: glucose leftovers, muscles, fat, tissue.

你的身體會不斷消耗它能找到的所有能量來源：剩餘的葡萄糖、肌肉、脂肪、組織。

After about two weeks, your immune system would be so weak, you could die from the common flu.

大約兩週後，你的免疫系統會非常虛弱，可能會死於普通流感。

Eventually, three weeks after your last sleep, you'd probably die of a heart attack.

最終，在你最後一次睡眠的三週後，你可能會死於心髒病發作。

If you've got a little extra muscle or fat on your body, you could stay alive just a little bit longer.

如果你的身體上有一點額外的肌肉或脂肪，你可以活得久一點，一點點而已。

But we don't recommend that anyone try this at home anyway.

但我們不建議任何人在家裡嘗試。

So grab yourself a pillow, and take a siesta.

找一顆枕頭，睡個午覺吧。

If it seems like you're always tired, make sure you're getting the prescribed six to eight hours of sleep per night.

如果你似乎總是很疲倦，請確保每晚有睡到規定的 6 到 8 小時。
