From the brains behind brains on, this is the moment of um.

Moment of Um comes to you from APM Studios. I'm Anna Goldfield.

Um.

Ooh, a good morning. I just woke up from a solid eight hours of snoozing.

I was having a dream about roller skating on the moon,

and then I woke up and realized I wasn't doing sweet stunts at one-sixth the Earth's gravity.

My eyes have all this gunk in the corners.

Blah!

How did that happen?

It's not like I rolled around and gunk and goop while I was sleeping.

Did my body actually make that?

I know my eyes aren't the only ones collecting goop overnight

because we got a great question about sleepy goobers

from a listener.

Hi, my name is Xavier from Sydney, Australia.

My question is, what produces sleep, the goo in your eyes, overnight when we are sleeping?

So I sleep, aka eye room or eye boogers, is just regular old eye discharge. It's made of a variety

of different things, including the normal secretions of the eye, that is, mucus, oil, and water,

as well as accumulated debris like dead skin cells and germs. In this sense, it's the same as a

booger because it's basically just dried out mucus and debris.

Hello, I'm Sotian Sarifor, and I'm one of the eye doctors at Yale Eye Center.

Like the skin in the nose, the eye is exposed to the air and all the junk in it.
