Oh, sorry about that.

But, you know, while I have you here, let's talk about boogers.

Why do we have boogers inside our nose?

There are lots of different kinds of boogers with various shapes, colors, and textures.

And believe it or not, they're in your nose for a pretty good reason.

Your nose is responsible for sniffing smells, but you can also think of it as a sort of filter.

Whatever is breathed in through your nose has to pass through hair and around mucous membranes in order to get inside your body.

It's like a first line of defense between you and whatever's trying to get in to make you sick.

The mucous membranes in your nose create a slimy substance to catch invaders like dirt, dust, pollen or bacteria.

When the mucus dries up and solidifies, that's a booger.

Snot can change color based on what you're breathing in.

But the color can also be a signal of what's happening inside your body.

Yellow or green could indicate you're getting a cold or fighting off some other sort of infection.

And white snot might mean you're congested.

When you blow your nose, you're clearing out all that gunk so your nose can keep filtering out more bad stuff.

So despite their gross reputation, boogers are actually great.

But don't even think about eating them.

After all, your body worked hard to filter out all that junk for a reason.
