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 cough-y,
and maybe you’re running a temperature. The flu is just another kind of cold, and
it’s really no fun — it makes you feel achy and sore, and hot, and all-around
miserable. But have you ever wondered what causes a cold
and the flu? Well, they’re 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! [Squeaks squeaks] Yes, Squeaks, since viruses can make us sick,
we sometimes call them germs. But, not all germs are viruses… but the ones that can cause the flu and colds definitely are! Now, in order to make you sick, the flu virus
has to get into your body first. It usually gets in through our nose…our
mouth…or our eyes. And once it gets in…the virus starts to
make copies of itself until there are lots and lots of them in there. But don’t worry! Your body has lots of 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 bodies makes mucus to trap the flu virus
and other germs that are in your nose and mouth. When mucus runs out 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
do we’re not feeling very well? That’s right, Squeaks – we sneeze! When you sneeze, air comes out of your mouth
and throat really quickly. 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 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, 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 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 school, or the store. And remember how we said the flu virus often
gets in through your nose, mouth, or 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 to do sometimes! And you can also keep of germs from spreading
to other people by covering up your coughs and sneezes! Remember, germs are leaving your body and
going into the air when you cough and sneeze. So, if you can, cover your mouth and nose
with a tissue, 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! Thanks for joining us on SciShow Kids! Do you have a questions you’d like to ask
