「如果一輩子都躺在床上,會發生什麼事情呢?」- What Would Happen If You Never Left Your Bed?


框選或點兩下字幕可以直接查字典喔!

Hey there. Welcome to Life Noggin.
哈囉。歡迎來到 Life Noggin。

You spend about one-third of your life sleeping. And chances are you are doing that in your bed. But what if you spent all your time in that bed? What if you never left? I mean, that memory foam can't hurt me, right?
你的人生有大約三分之一的時間都在睡覺。而你很可能是在床上睡覺。但如果你無時無刻都躺在床上會怎麼樣呢?如果你從未離開床呢?我的意思是,那張記憶床墊應該人畜無害吧,對嗎?

Uh. Right?
呃。對吧?

Oh, right. I know the answer.
喔,對。我知道答案。

Sadly, it can. And believe it or not, NASA paid a guy 18,000 dollars to lie in bed for 70 days. They wanted to study the effects of microgravity on the human body, and lying down for so long stimulates the effects of long-haul flights on astronauts' bodies.
不幸的是,你錯了。不論你信不信,NASA 曾以一萬八千美元(約台幣五十五萬)為酬勞,要一名男子躺在床上七十天。他們想要研究微重力對人體的影響,而這麼長時間的躺臥會引起像是太空人長期飛行後對身體的影響。

The beds were tilted back six degrees, causing the bodily fluids to shift to the upper body, which duplicated some of the effects of low-gravity environments.
床向後傾斜六度,導致體液流向人體上半部,這會複製一些低重力環境的影響。

After the 70 days, the first time the volunteer was vertical, his heart rate jumped to 150 beats per minute, and it felt like he was going to collapse, which is definitely not great for an otherwise healthy man.
七十天之後,當那名志願者第一次站直身軀,他的心跳頻率高達每分鐘一百五十下,而且感覺他就要昏倒了,這對一名原本可以很健康的男子來說絕對不是好事。

But this study is different than most because it simulated microgravity.
但這個研究因為模擬微重力,本質上有很大不同。

Instead, let's talk about what would happen if you never left a normal bed that wasn't tilted backwards.
不說這研究,我們來談談如果從未離開一張正常且未向後傾斜的床會發生什麼事。

Well, firstly, you'd probably start to develop bedsores. These are caused by the pressure on the skin that limits the amount of blood flow to the skin and nearby tissues.
嗯,首先,你可能會開始生出褥瘡。褥瘡是因為壓力施加在皮膚上,限制了流入皮膚和鄰近組織的血流量。

Basically, imagine this: The tissue between your bones and the bed is under a lot of pressure from your body weight. And if that pressure is great enough, the nutrient-rich blood won't be able to reach your cells, and they will be damaged and eventually die.
基本上,你可以這麼想像:介於骨頭跟床之間的人體組織會承受許多身體重量帶來的壓力。而如果壓力夠大的話,營養豐富的血液就到不了細胞,這些細胞會受損,最後死亡。

The sores usually occur in areas like your tailbone, hips, and shoulder blades. And be warned: They're not pretty, not even with a little bit of coral blue lipstick.
褥瘡通常會發生在像是尾椎骨、臀部,和肩胛骨等部位。別說沒提醒:褥瘡一點都不好看,即使擦上一點珊瑚藍唇膏也於事無補。

Also, you'll start to get weaker, especially if you are immobile in the bed. See, muscles at complete rest lose 10 to 15 percent of their strength per week. In just three to five weeks, the muscle has lost nearly half of its strength. So good luck lifting that laptop of your lap as easily as before.
此外,你會變得越來越虛弱,特別是如果你在床上動也不動。瞧,肌肉完全休息的時候,每週會喪失百分之十到十五的力量。短短三到五個禮拜,肌肉就會失去將近一半的力量。所以,如果你想跟從前一樣輕易拿起腿上的筆電,就祝你好運了。

Complete rest will also cause your endurance to decrease, leading to fatigue and even more inactivity. And your muscles will begin to atrophy too, losing their mass.
完全休息也會降低耐力,引起疲勞甚至會讓你感到更無力。而你的肌肉也會開始萎縮,失去重量。

And your bones also lose their mass, eventually stabilizing around 40 to 70 percent of their original mass. This is caused by increased bone resorption, which is a process that breaks bones down, eventually fast enough that it outweighs the rate of new bone growth. And this can lead to conditions like osteoporosis.
此外,你的骨頭也會失去重量,最終剩下原有重量的百分之四十到七十左右。這是因為骨吸收增加,而骨吸收是骨頭分解的一個過程,最終速度會快過於新骨頭生長的速度。而這可能會導致像是骨質疏鬆等的症狀。

On top of all of that, every two days of immobilization, your resting heart rate increases by one beat per minute, eventually plateauing. And even more, your blood volume decreases as well. Because of this, since the blood carries oxygen, there is less oxygen uptake by your cells, which means you'll get tired much more easily.
除了所有這些之外,每兩天不活動,你的每分鐘安靜心跳率會增加一下,最後緩慢升高而且居高不下。此外,你的血液量甚至也會減少。也因此,因為血液攜帶氧氣,你的細胞能吸收的氧氣量會降低,這也意味著你會更容易感到疲倦。

And that's not even all of it, people. There are tons of other negative effects of bed rest, like increased anxiety, increased risk of kidney stones, and an increased risk of pneumonia.
而且還沒完呢,大家。長期躺在床上還有許多負面影響,像是焦慮升高、更容易罹患腎結石,更容易感染肺炎。

So while your bed may be incredibly comfortable, you should definitely try to limit the time you spend in it. Trust me. Your body will thank you.
所以儘管你的床可能非常舒適,你絕對應該要限制躺在床上的時間。相信我。你的身體會感謝你。

So, you Sleepy Sallys, how much time do you spend in your bed? Or are you more of an active type? Let me know in the comments section below.
所以,你們這些懶惰鬼都花多少時間躺在床上呢?還是其實你們是活力派的?在下面留言區讓我知道吧。

  • 「如果...會怎麼樣」- What If

    But what if you spent all your time in that bed?
    但如果你無時無刻都躺在床上會怎麼樣呢?

  • 「分解」- Break Down

    This is caused by increased bone resorption, which is a process that breaks bones down, eventually fast enough that it outweighs the rate of new bone growth.
    這是因為骨吸收增加,而骨吸收是骨頭分解的一個過程,最終速度會快過於新骨頭生長的速度。

  • 「除了某事之外」- On Top Of Something

    On top of all of that, every two days of immobilization, your resting heart rate increases by one beat per minute, eventually plateauing.
    除了所有這些之外,每兩天不活動,你的每分鐘安靜心跳率會增加一下,最後緩慢升高而且居高不下。
