Many people catch a cold in the springtime and/or fall. It
makes us wonder: if scientists can send a man to the moon, why
can't they find a cure for the common cold? The answer is easy.
There are literally hundreds of kinds of cold viruses out there.
You never know which one you will get, so there isn't a cure
for each one.
When a virus attacks your body, your body works hard to get
rid of it. Blood rushes to your nose and brings congestion with
it. You feel terrible because you can't breathe well, but your
body is actually 'eating' the virus. Your temperature rises and
you get a fever, but the heat of your body is killing the virus.
You also have a runny nose to stop the virus from getting to
your cells. You may feel miserable, but actually your wonderful
body is doing everything it can to kill the cold.
Different people have different remedies for colds. In the
United States and some other countries, for example, people
might eat chicken soup to feel better. Some people take hot
baths and drink warm liquids. Other people take medicines to
stop the fever, congestion, and runny nose.
There is one interesting thing to note - some scientists
say taking medicines when you have a cold is actually bad for
you. The virus stays in you longer because your body does not
have a way to fight it and kill it. Bodies can do an amazing
job on their own. There is a joke, however, on taking medicine
when you have a cold. It goes like this:
It takes about 1 week to get over a cold if you don't take
medicine, but only 7 days to get over a cold if you take
medicine.
