How a common cold develops | Bupa Health?

A common cold is when tiny germs sneak into your body and start a sneaky party inside your nose and throat.

Imagine you're playing with your favorite toy, and suddenly, someone throws a bunch of small, sticky balls at you. These balls are like the germs from a common cold, they land on your nose or throat, which is like the front door of your body. Once they’re inside, they start to multiply, just like when you leave cookies out and ants come crawling in.

Once the germs are inside, they start to cause a bit of chaos. They might tickle your nose, making it runny, kind of like how water comes out of a hose when you turn it on too much. Or they could give your throat a scratchy feeling, like when you eat too many strawberries and your tongue feels all tingly.

Your body notices the germs are there, so it sends out soldiers (called white blood cells) to fight them off. This battle can make you feel tired or achy, just like after a big playdate where you ran around for hours!

Eventually, the soldiers win, and you start to feel better, but not before you’ve had a few sneezes and sniffles!
