Oh, bless you！
Squeaks isn’t feeling very well today.
Everyboy gets sick, even robots and rats.
And getting the cold or the flu can be sort of scary.
But sometimes the more you know about something,
the less scary it is.
So Squeaks and I decided to take a look back
at everything we’ve learned about how we get sick,
and what we can do to feel better.
First, why did you sick the first place
and what did your body do to help you feel better.
When it gets cold outside,
it’s time to bundle up and take good care of yourself,
because cold weather time is cold and flu season.
You’ve heard of colds. Everyone gets them.
That’s when you get sneezy and coughy and
may be you’re running a temperature.
The flu is just another kind of cold
and is really no fun
它使你全身疼痛 发炎 发热 周身不适
It makes you feel achy and sore and hot and all-around miserable.
But have you ever wondered what causes a cough and the flu.
Well, they are both caused by something called a virus.
Viruses are very small.
Too small to see even with most microscopes.
They can make a big difference in your body, though,
because they can make you sick.
是的 吱吱 由于病毒可以致病
Yes, Squeaks, since viruses can make us sick,
we sometimes call them germs.
But, not all germs are viruses.
But the ones that can caused the flu and colds definitely are.
Now in order to make you sick, the flu virus has to get into your body first.
通常经由我们的鼻腔 口腔 或是眼部进入
It usually gets in through our nose, our mouth or our eyes.
And once it gets in, the virus starts to make copies of itselves
until they are lots and lots of them in there.
But don’t worry, your body has ways to fight back.
It might seem kind of weird but
sometimes it’s the things that your body does to fight the virus
and other germs that makes you feel kind of yucky.
Take for example, mucus,
that’s the sticky runny stuff that comes out of your nose.
Your body makes mucus to trap the flu virus and other germs
that are in your nose and mouth.
When mucus runs down in your nose, it carries the flu virus with it,
along with other stuff your body has used to knock them out .
Gross, maybe, but it works.
When mucus runs down the back of your throat,
after a while, it can make it hurt too.
That’s why you sometimes get a sore throat when you’re sick.
But washing out the virus isn’t the only thing
your body can do to fight the flu.
Can you think of another thing that most of us do
when we’re not feeling very well.
When you sneeze, air comes out of your mouth and throat really quikly.
As the air goes by, it picks up some of the virus pieces
and carries them outside of your body.
So, sneezing is your body’s way of sending
viruses and other germs on their way.
Now, if you’ve ever had the flu,
you probably know what a fever is.
A fever is another way that our bodies try to get rid of the virus.
When germs are inside your body,
it can make itself hotter than normal.
And guess what? Viruses hate that.
Because when it gets too hot,
it’s harder for viruses to make copies of themselves.
And that helps your body gets rid of germs more easily.
So, your body has lots of cool ways to defend itself.
But, what else can you do to make youself feel better when you get sick?
Well, getting lots of rest is one of the best things
you can do when you’re not feeling well.
When you rest, you save energy,
and your body can use that energy to get rid of the virus.
Another thing you can do is drink a lot.
Healthy things like water, some juices and even soup
will give your body the things it needs to help you get feeling better soon.
Of course, the best thing to do is to not get sick in the first place.
And to help with that, the number one thing to do is
wash your hands a lot.
Plain old warm water and soap can go a long way
in keeping you from getting sick.
It’s especially important to wash your hands
when you get home from scool or the store.
And remember how we said that
the flu virus often gets in through your nose, mouth, and eyes.
The other thing you can do is to keep your hands
away from these parts of your body as much as you can.
Even though it can be hard to remember sometimes.
And you can also keep germs from spreading to other people
by covering up your coughs and sneezes.
Remember, germs are leaving your body
ang going into the air when you cough and sneeze.
所以 如果你能做到 请用纸巾盖住口鼻
So, if you can, cover your mouth and nose with a tissue,
and then throw the tissue away.
And then, wash your hands.
If you can’t get to a tissue in time,
then cough into your elbow instead of your hands.
So, try to keep clean and stay healthy,
so you can go outside and enjoy the cold weather.
噢 吱吱 你知道在流鼻涕的时候应该盖住鼻子吗
Oh, Squeaks, you know you should cover your nose when you sneeze.
Do you want me to get sick too?
哦 对不起 小家伙 给你盖上
Oh, I’m sorry, buddy, here you go.
Ha! Sneezing is one way your body keeps germs and other gross stuff out.
So if you don’t cover your mouth,
you might just give everyone around you your germs.
It’s cleaning day.
Today we’re doing a little tidying up around the floor.
We are sweeping and dusting.
对不起 伙计们 哦 这真是个大喷嚏
Sorry, guys. Oh, it’s a big sneeze.
You know, when I think about it,
cleaning is not the only time I sneeze.
Sometimes I sneeze when I am around the flowers,
and I sneeze a lot when I have a cold.
And I bet you can think of something that makes you sneeze too.
It happens to everyone, but,
have you ever wondered why.
Every sneeze starts to right inside of your nose.
The inside of your nose is covered with a lot of really tiny, really fun hairs.
And there is also a lot of mucus inside your nose.
哟 黏液 也就是粘糊糊的东西
Yo, mucus. This’s gooey sticky stuff
that shows up in your tissue when you blow your nose.
The hair and mucus work together to catch
tiny particals that’s in the air that you breath in.
Like bits of dust or pollen of flowers
or even the pepper you may put on your food,
these things clog off the inside of your nose, causing you to get irritated.
which means if you are kind of tickly,
you may also feel that tickle when you are sick.
That’s because the inside of your nose, is being attacked
by lots and lots of tiny things like viruses or bacteria.
When your nose gets irritated by any of these things,
it sends signal to your brain,
that tells it “We gotta get this stuff out of your nose!
It’s time to sneeze!”.
So you take in a big breath of air,
the muscles in your belly and chest and throat are squeezed really hard,
you close your eyes, and then the air leaves your nose and mouth,
and a big noisy blasts.
Which hopely clears all those irritating things out of your nose.
Some scientists study sneezes, and they find that sneezing
can send air fly out of our nose and mouth
at over a hundred kilometers per hour,
that’s the best of some of race cars,
and sneezing is what’s called a reflex.
A reflex is something that your body does without you have to think about it.
Blinking is another kind of reflex,
when dusts and other little things that bother your eyes,
and so was coughing, if something is tickling your throat.
Reflexes help protect your bodies from geting hurt or becoming sick.
So sneezing helps you keep healthy by clearing out things inside of your nose.
If you didn’t sneeze, some of the particals or germs inside your nose
might move deeper inside of your body, and those might make you sick.
A nice big sneeze also helps smooth that all that little hairs in your nose
and spreads your fresh mucus inside your nose to get already to trap more particals.
But when you sneeze, don’t forget to cover it up.
Because air isn’t the only thing that leaves your body
when your nose starts to go off.
Sneezing also blasts saliva or spit
and a lot of germs from our mouth into the air around us.
Some scientists think that germs launch by a sneeze can travel about 60 meters,
which it’s over half the way of a football field.
So when you sneeze, it’s important to keep those germs from spread
by putting something in front of them.
If you don’t have a tissue handy, sneezing to your elbow.
And don’t forget to wash up in soap water afterwards.
记得 安全打喷嚏 保持健康
And remember, sneeze safely, and keep healthy.
Oh ho~ Having a running nose is no fun,
but boogers are important part of your body’s anti-germs security system.
Snot is really sticky,
so it can trap germs before they get farther into your body.
So, it’s helpful stuff. Oh, even it’s pretty gross.
Here’s a handy tip for those of you who happen to have a human body.
When something comes out of your body on a regular basis,
your body’s probably got a good reason for getting rid of it.
Like, how sometimes, if there is too much gas in our stomachs,
it’ll just go right back up the way it came in.
And generally speaking,
the same idea goes for whatever you might find coming out of your nose.
Our noses get full of slimy, gooey and sometimes crusty stuff.
You know what I’m talking about. Boogers.
And yeah, boogers are pretty gross.
But keep in mind that almost everything that makes up our bodies has a purpose.
That is, until it’s time for it to leave.
So, where do boogers come from? And why are they there?
Let’s start with what hapens when you take in a breath.
When you breath in or inhale,
you’re not only pulling air into your lungs,
you’re also taking in a lot of what’s floating around in the air,
stuff that’s too small to see.
Like dust and dirt, pollen from plants,
smoke and other kinds of pollution, and germs.
If these things get into your body, they could make you sick.
But thankfully your body has a powerful weapon
to help trap these things before they can get too far.
And that weapon is mucus.
Yep, the same gooey slimy snot that clogs up your tissue
and runs out of your nose when you have a cold or allergies.
That stuff has a purpose.
When you breath in and out,
air moves through your mouth and nose, and down to your lungs.
These parts of your body make up your respiratory system.
The job of your respiratory system
is to help your body get oxygen it needs from the air.
And all of the parts of your respiratory system
are lined with a thin layer of mucus,
even when you’re not sick, your body makes a lots of mucus.
But usually you don’t notice it,
that’s because the mucus is normally really thin and watery.
It helps keep the parts of your respiratory system moist and healthy.
But it’s also really really sticky.
And as the air you breath passes over it,
空气中的很多微小的颗粒 病菌 尘埃
many of the teeny tiny particles in the air, the germs, dust
and other irritating things stick to it and get trapped.
Then it’s time to take out the trash.
Little hairs in the back of your nose and your lungs called cilia,
act like brooms, sweeping the mucus to your throat,
where it gets swallowed and goes right to your stomach.
But don’t worry,
the inside of your stomach is full of chemicals
that help destroy all of the germs and another stuff.
So you don’t get sick.
But what about that stuff up your nose.
Well, sometimes the air you breathe in is really dry,
and when you breath in a lot of dry air,
the mucus that lines in your nose
instead of being thin and watery, gets dry and crusty,
kind of like what happens to mud when it dries out.
The hard things left behind, dried up mucus and dirt,
are the boogers.
The stuff stuck in that mucus when it dries out
can change the color of what comes out of your nose.
Sometimes mucus has tiny bits of blood, which makes it brown.
And sometimes your body sends cells to kill the germs stuck in the mucus,
and these cells have chemicals in them,
that can make the mucus kind of green or pink.
But no matter what’s in them,
Blow your nose in a tissue, don’t pick it.
Boogers are full of germs that were traped by that mucus
and some of those germs could still spread disease.
After all, the boogers are there because
mucus has kept that stuff out of your body
So keep a tissue handy and blow your nose,
and wash your hands thoroughly afterwards.
Good manners are also good science.
Your body works hard to stop germs and keep you from geting sick.
But there are things you could do to help too.
What important thing you can do is to wash your hands a lot.
Especially after you sneeze.
But how do soap wash away the germs and other gross staff
that can make you sick.
You know the very best way to learn something?
By asking questions.
No one knows everything after all.
So something comes up that you just don’t understand,
ask someone that you think could help.
I’ve been thinking about this because of our friend the Giant Squead.
A coupe of weeks ago,
we were talking about why things flow on the water.
我说 当你洗澡时 有些东西会浮在水上
And I said that something flow on the top
when you are taking a bath and other things don’t.
But Squead lives in the ocean and he doesn’t take bath,
So he ask me what bath was and why we take them.
By the way, what’s a bath?
Well, up here we like to clear ourselves
by soaking in a topful nice warm and soapy water.
That sounds gross, do you mean that
humans just walk around all day getting dirty?
And you know what’s really great,
after one of our viewers Zoey , saw that episode,
She thought of another question.
So she wrote to us and ask, how do baths work?
And how do soap and water get us clean?
Another great question.
First, water is good at dissolving a lot of things.
When I say water dissolve something,
I mean that it breaks it down to small pieces,
that can mix in with the water.
So for example, when you reach your muddy hands under a running faucet,
two things happen,
one, the force of water push some of mud off your hands.
And two, the water dissolves some of the staff that makes the mud and
并冲到下水道中 很有意思 对吗
wash it down to the drain. Cool. Right?
But what about bath, before we can dive into that,
we should probably take a quick look at
how we get dirty in the first place.
Your skin makes its own oil,
this nature oil helps your skin stay soft and healthy.
And your skin also makes sweat, which we’ve talked about before too.
Sweat is mostly soiled and water.
When the water in your sweat drys up,
it helps cool your body down.
But leaves that soiled and other staff behind.
So all in the day, dirty dust sticks to the soiled and oil.
If you let that dirty noil build up for too long,
it becomes a good place for bacteria and other very tiny living things.
So it’s a good idea to wash often.
Now when you getting the top,
the water dissolves the soiled and lots of dirt that get stuck under your skin.
But one thing water can’t dissolve
it’s the oil itself.
Why? Because oil and water just don’t mix .
You can see so for yourself.
If you pour some water in a glass, and add a bit of cooking oil,
you’ll see that they form two completely different layers.
Water particles are small, and stick together very tightly.
But oil particles are bigger and don’t stick together as well.
So If water can’t make oil to washed away,
then how can you get that oil off your skin?
That’s where soap comes the rescue.
Soap can dissolve oil
but can’t stick it really well and help wash it away.
If you could look the particles that make up soap,
you could see that they each have two different ends.
And each end is attract to or pull toward different kinds of things.
One end of the soap particle is pull toward water,
and other is pull toward oil.
所以当你将肥皂 油 水混在一起的时候
So when you mix soap with oil and water,
one side of each little soap particle sticks to the oil,
while the other side sticks to the water.
And then, when you rinse off,
the soap, oil and water all go right down the drain.
So now you know how water and soap work together
to get our Squeak clean in the tub.
And If you happened to see Squead before I do, tell him yourself.
好的 吱吱 让你变好点还有一件事你要做
Ok, Squeaks. There’s one more thing that you have to do to get better.
就是休息 到了你跟我们的观众说再见了 然后去躺下
Rest. It’s time for you say googbye to our friends and go lie down.
The next time you get a cold or the flu.
Remember that your body is working over time to help you feel better fast.
Just get plenty of rest, and drink lots of water.
And you’ll be outside play again in no time.
