Oh what you squeeze it isn't feeling
very well today
everybody gets sick even robot rats and
getting the cold or flu can be sort of
scary but sometimes the more you know
about something the less scary it is so
sweet 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 it in the first place and
what is your body do to help you feel
better when they get cold outside it's
time to bundle up and take good care of
yourself because cool weather time it's
cold and flu season you heard of cold
everyone gets them that's when you get
me and copy and maybe you're running a
temperature and flow is just another
kind of cold and it's really no fun in a
CPL 1804 and hot and all-around
miserable but have you ever wondered
what causes a cold and the flu
what they're both caused by something
called a virus viruses are very small
too small to see you met with most
microscopes they can make a big
difference in your body though because
they can make you sick
yes weeks since viruses can make a sick
we sometimes call them germs but not all
germs are viruses but the ones that can
cause the flu and cold definitely are
now in order to make you sick
the flu virus have to get into your body
first it usually gets in through our
nose or mouth or our eyes and once we
give him the virus starts to make copies
of itself until there are locks every
one of them in there but don't worry
your body has ways to fight back it
might seem kind of weird but sometimes
if the things that your body doesn't
fight the virus and other germs that
makes you feel kind of yucky
take for example mucus that's the sticky
running 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 you get run
down your nose
it carries the flu virus with it along
with other stuff your body have used to
knock them out gross maybe but it works
when you get run down the back your
throat after awhile it can make it hurt
to that
don't you sometimes get a sore throat
when you're sick but washing out the
virus even 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 you're right
weeks we need when you sneeze air comes
out of your mouth and throat really
quickly as the air boom by it picks up
some of the virus pieces and carries
them outside of your body so sleeping 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 you can make itself
hotter than normal and guess what
viruses hate that because want to give
too hot it's harder for the viruses to
make copies of themselves and that helps
your body get rid of germs more easily
so your body has lots of cool ways to
defend itself but what else can you do
to make yourself feel better when you
get sick
well I'm giving lots of rest is one of
the best things you can do when you're
not feeling well when you rescue scene
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 from juices
and even soup will give your body the
things that 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
oh ha 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 school or
the store and remember how we said that
the flu virus often get 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 them from spreading to
other people by covering up your costume
sneezes remember yours are leaving your
body and going into the air when you
cough entreat so if you can have your
mouth the nose of the tissue and then
roll the tissue away and then wash your
hands if you can't get you a tissue in
time then cough into your elbow instead
of your hands so try to keep clean and
stay healthy even go outside and enjoy
the cold weather
Oh squeeze you know you want to cover
your nose need you will need to fix hill
it's all right buddy here you go
hi leaving is one way your body keeps
germs and other gross stuff out so you
don't cover your mouth you might just
get everyone around you your germs
hey it's cleaning day today we're doing
a little tidying up around the fort
we're sweeping and dusting oh yeah I
said the Pixies you know when I think
about it
leaving not the only time I sneeze
sometimes I speed when I'm around
flowers and I think a lot when I have a
cold and I bet you can think of some
things that make you sneeze to it
happens everyone's what have you ever
wondered why everything starts right
inside your nose the inside of your nose
is covered with a lot of really tiny
really fine hairs and there's also a lot
of mucus inside your nose
yep mucus the same gooey sticky stuff
that showed up in your tissue when you
blow your nose the hair and mucus work
together to catch tiny particles that
are in the air that you breathe in like
six of dust or pollen from flowers or
even a pepper you might put on your food
these things quad up the inside of your
nose causing it to get irritated which
means it feels kinda quickly
you might also feel that pickup when
you're sick that's because the inside of
your nose is being attacked by lots and
lots of tiny little things like viruses
or bacteria when you're not get
irritated by any of these things
extensive signal to your brain that
tells it
we got to get this stuff out of your
nose it's time to sneeze you taking a
big breath there the muscles in your
belly chest and drop off please really
hard
you close your eyes and then the air
leave your nose enough in a big-name
blast show which hopefully clears all
those irritating things out of your nose
some scientists study sneezes and they
found its needing can set their flight
out of her nose and mouth at over 100
km/h that's fascism race cars and
speeding and what called a reflex a
reflex is something that your body does
without you having to think about it
blinking is another kind of reflex when
Dustin other little things that bother
your I
and so it coughing if something is
picking your throat reflexes help
protect our bodies from getting hurt or
becoming sick so leaving help you keep
healthy like query on the inside of your
nose if you didn't meet some of the
particles or germs inside your nose
might move deeper inside your body and
soul might make you sick
a nice big sneeze also how cruel that
all the little hairs inside your notes
and spread around fresh new kids inside
you know to get it all ready to trap
more particles 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 meeting
also glass the light more spit and a lot
of germs from our mouth into the air
around us some scientists think that
germs watched by sneeze can travel about
16 years which is also half the length
of a football field
so when you please it's important to
keep those germs from spreading like
putting something in front of them if
you don't have a TV heavy into your
elbow and don't forget to wash it with
soap and water afterwards and remember
me safely and keep healthy whole having
a runny nose is no fun but boogers are
an important part of your body and I
German security systems not is really
sticky so I can trap door before they
get farther into your body so it's
helpful stuff all even if it's pretty
gross
you're in the handicap for those of you
who haven't a half 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's too much gas in
our stomachs will just go right back up
the way came in and and generally
speaking the same idea goes for whatever
you might find coming out of your nose
our noses get full of climbing doing
sometimes crusty stuff you know what I'm
talking about
boogers and yeah those are pretty gross
but keep in mind that almost everything
that makes up our bodies have 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 happens when you
take in a breast when you breathe in or
inhale you're not only pulling air into
your lungs
you're also taking in a lot of what
floating around in the air stuff that's
too small to see like dust and dirt
going from plants local other kinds of
pollution and germs in these things get
into your body they could make you sick
but thankfully your body have 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 club
w tissue and runs out of your nose when
you have a cold or allergies that stuff
has a purpose when you breathe in and
out air moves through your mouth and
nose and down to your lungs these parts
of your body makeup your respiratory
system the job of your respiratory
system is to help your body get the
oxygen it needs from the air and all the
parts of your respiratory system are
lined with a thin layer of mucus even
when you're not sick
your body makes a lot of mucus but
usually you don't notice it
that's because the mucus is normally
really thin and watery it helps keep the
part of your respiratory system moist
and healthy but it's also really really
sticky and as the air you breathe passes
over it
many of the heat I particles in the air
the germs dust and other irritating
things ticket and get trapped then it's
time to take out the trash little hairs
on the back of your nose and your lungs
called filia asked like broom sweeping
the mucus year throughout where gets
swallowed and goes right you're
something but don't worry the inside of
your stomach is full of chemicals to
help destroy all the germs and other
stuff you don't get sick but what about
that stuff up your nose
well sometimes the area breathing is
really dry and when you breathe in a lot
of dry air the mucus that line your nose
instead of being thin and watery gets
dry and crusty kind of like what
happened somebody when it dried out the
hard things left behind dried up mucus
and dirt are the boogers stuff stuck in
that mucus when it dries out can change
the color of what comes out your nose
sometimes you get has tiny bit of blood
which makes it brown and sometimes your
body send cells to kill the germs stuck
in the mucus and nice out have chemicals
in them they can make them you could
kind of green or pink but no matter
what's in them all your nose in it is
you don't pick it over full of germs
that were trapped by that mucus and some
of those germs can still spread disease
after all the boogers are there because
you could have kept that stuff out of
your body so keep you happy and blow
your nose and wash your hands thoroughly
afterwards good manner
are also good science your body works
hard to stop germs and keep you from
getting sick but there are things that
you can do to help you one important
thing you can do is to wash your hands a
lot especially after you sneak but how
does so wash away the germs and other
gross stuff that can make you sick you
don't have a 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
at someone anything could help
I've been thinking about this because of
our friend the giant squid a couple of
weeks ago we are talking about whiting
flow in the water and I said that
something's floatin the tub when you're
taking about and other things don't but
split within the ocean and he doesn't
take baths so he asked me what that were
and why we take them right
what about well up here we like to clean
ourselves by filling in a couple of nice
warm soapy water hose gross dream
induction humans just walk around of dig
getting dirty and you know it's really
great after one of our viewers Zoe saw
that episode she thought of another
question 102 hasn't asked how do bad
work and how to filter water get us
clean another great question first water
good at dissolving a lot of things when
I say water dissolve something I mean
that it breaks it down into smaller
pieces that get mixed in with the water
so for example when you rinse your my
hands under a running faucet two things
happen one the force of the water pushes
the mud off of your hands and to the
water dissolves some of the stuff that
makes it the mud and washing it down the
drain
cool right but what about baths 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 natural oil helps your skin
stay soft and healthy and your skin also
makes wet which we talked about before
to what is mostly salt and water when
the water in your sweat dries up it
helps cool your body down but leave that
salt and other stuff behind so all
during the day dirt dust kicks to the
salt and oil if you let the dirt oil
build-up for too long it becomes a good
place for bacteria and other very tiny
living things that's a good idea to wash
often now when you be in the Cubs the
water dissolves the salt and a lot of
the dirt i get stuck on your skin but
one thing water can't dissolve is the
oil itself
why because oil and water just don't
make
you can see so for yourself if you pour
the water in a glass and a bit of
cooking oil
you'll see that before two completely
different layers water particles are
small and stick together very tightly
but soil particles is bigger and don't
stick together as well so water can make
soil to wash away then how can you get
that oil off your skin that's where self
come to the rescue
so can't dissolve oil but it can stick
to it really well and help wash it away
if you could look at the particles that
make up so you can see that they each
have two different ends at each end is
attracted to or pull toward different
kinds of things one end of the particle
is pulled towards water and the other is
pulled toward oil Sony makes soap with
oil and water one side of each little
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 a squeaky-clean in the
tub and if you happen to be split before
I do tell him yourself
okay sweet there's one more thing that
you have to do to get better rest
it's time for you to say goodbye to our
friends and go lie down the next time
you get a cold or the flu
remember that your body is working
overtime to help you feel better fact
just get plenty of rest and drink lots
of water and you'll be outside playing
