溺水时你的身体发生了什么?

What Really Happens To Your Body When You Drown?

Hey there and welcome to Life Noggin.
嗨 欢迎来到《品生活》
Every year, there are over 370,000 drowning deaths worldwide,
全球每年有超过370000人溺水死亡
with children under 5 being the most at risk.
其中小于五岁的儿童最为危险
And with all the drowning deaths you see in movies and TV,
你在电影和电视中看到的溺水死亡
it’s no wonder that people are afraid of dying that way.
人们害怕这种死亡的方式也不足为奇
But what’s actually going on during that process?
但溺水过程中到底发生了什么?
Well, firstly, drowning isn’t like how you see it in the movies
首先 溺水不像你在电影里看到的那样
there’s not a lot of thrashing around or yells for help.
不会有过多的挣扎或呼救
Typically, it’s a silent act, where the person’s mouth sinks below the surface of the water
通常溺水是无声 溺水时人的嘴巴溺于水下
and then reappears as they try to breathe.
试图呼吸时又挣扎着露出水面
See, once they can no longer hold their initial breath and start to hyperventilate
一旦他们不能憋住最初一口气开始急促呼吸
they might aspirate water, triggering something called a laryngospasm.
他们可能会吸进水 引起喉肌痉挛
This is where the person’s vocal cords spasm,
这个现象发生在声带出现痉挛的部位
blocking their airways and protecting their lungs.
以便 封闭呼吸道和保护肺部
However, it also inconveniently makes yelling for help significantly harder to do.
但是 这也让呼救明显变得更加困难了
Since the person can’t take in any fresh air, their oxygen supply starts to fall,
由于溺水者无法呼吸 他们的供氧量下降
potentially leading to a condition called hypoxia,
很可能会导致缺氧
this is where there’s not enough oxygen reaching the body’s tissues.
在这种情况下 没有足以能到达人体组织的氧气
And eventually, as the person becomes unconscious, there’s a relaxation of their airway,
最后 当他失去意识 他的气管就会打开
allowing their lungs to fill with water.
肺部开始充水
Depending on how long the person has gone without air,
根据溺水者缺氧时长
varying levels of damage can occur.
会造成不同程度的损伤
For example, a 2013 study found that the likelihood of surviving with little to no brain damage
如 有研究表明溺水10分钟及以上
was very low after being submerged for 10 minutes or more.
生还且几乎没有脑损伤的可能性很小
The lack of oxygen can also lead to cardiac arrest.
缺氧也会导致心脏停搏
So, basically what I’m saying is that drowning is absolutely terrifying.
所以 综上我想说的是溺水很可怕
so please wear your life jackets, kids.
孩子请穿上你的救生衣
They’re cool and will keep you safe.
它们好用并且保你安全
I know I look fantastic in my floaties
我知道我穿浮水袖好看极了
On top of all that, if the person is in really cold water, there’s also the fear of hypothermia
重要的是 若人在很冷的水中 也会面临
— where the core body temperature falls below 35 degrees Celsius.
重要部位的体温低于35度导致的低温症的危险
When hypothermia sets in, it’ll cause the body to start shivering intensely
当低温症出现时 身体随之开始剧烈抖动
and the person might act clumsy and confused.
人可能会反应迟钝和犯迷糊
Their bodies slow down, including their respiration, heart, and metabolic rates.
身体的呼吸 心率和新陈代谢开始变慢
And eventually, they might lose consciousness and even die.
最终 他们可能失去意识甚至死亡
Let’s all take a moment to mourn the loss of Jack from Titanic
我们为泰坦尼克号中Jack默哀一会
but come on, there was seriously enough room on that door for him too.
但是 木门明明还有足够的地方留给他
While hypothermia is a serious threat,
尽管体温过低是一个严重的威胁
it may actually help to prevent the effects of hypoxia.
事实上它可能会改善缺氧的影响
See, it can trigger the diving reflex, where blood vessels constrict and the heart rate
可引发潜水反射 使血管收缩 降低心率
slows and blood is diverted to the parts of the body that need it the most, like the brain.
使血液流向最需要它的部位 如大脑
Hypothermia also decreases how much oxygen is needed by the body’s tissues — meaning
低温症也减少人体组织所需氧量 意味着
that it can actually prolong survival and help prevent the tissue damage from hypoxia.
它可延长存活时间且避免组织因缺氧损伤
In fact, hypothermia and the diving reflex is often cited as a big reason
事实上 低温症和潜水反射通常被认为是
why some young children have been able to survive drowning after being under the water for far more than 10 minutes.
孩子溺水超过10分钟仍幸存的一大原因
That being said, do not try to replicate that yourself.
话虽如此 切勿尝试亲身证明
It’s definitely best to stick with those huge inflatable pool toys instead.
最好是玩巨型泳池充气玩具
I call dibs on the flamingo.
我希望乘着火烈鸟
Are you afraid of the water?
你害怕水吗?
What life-threatening situation do you want us to talk about next?
你希望下期节目聊什么危机生命的情况
This episode was a little bit morbid, so why don’t we celebrate the fact that you exist!
本期有一点病态 何不庆祝一下我们尚在
If you want to know the odds of you being born and how lucky you are to be alive, check
如果你想知道你出生的概率和活着多幸运
out this video.
请打开这个视频
In most cases, in order for you to be alive,
多数情况下 为了让你活着
your parents had to meet
你父母必须见面
Assuming that your mother could meet,
假设你母亲在她黄金约会年龄时
let’s say one new person a day during her prime dating years,
每天约见一人
she would have met around 10,000 people
她会遇到约1万人
As always, I’m Blocko. This has been Life Noggin.
我是bloxko 这里是《品生活》
Don’t forget to keep on thinking!
不要忘了保持思考哦!
