Here's why you wake up in the morning with 'sleep in your eyes'

There are plenty of reasons why waking up in the morning is the grimmest thing we'll do all day.

But daybreak is even more dolorous if we're unlucky enough to wake up with our eyes glued shut.

When this happens, we generally say that we've awoken with 'sleep in our eyes'.

But in America, the horrid peeper adhesive is called "eye boogers" - which makes it sound a million times more disgusting.

Now the science experts from a YouTube channel called SciShow have stepped in to explain the make-up of this yucky substance.

Michael Saranda, host of the show, said : "Mr Sandman, I asked you to bring me a dream and you brought me were these gross eye boogers.

"So what is this goopy junk which collects in the corners of my eyes while I'm asleep?"

He explained that scientists don't have an official name for the "crusty residue", although it is often referred to as rheum or gound.

Rheum is always present in the eye, which uses a liquid called "tear film" to keep the peeper lubricated.

When we wake up, the tear film has gathered in our eyes because we haven't been blinking.

It has also become mixed with oil, bacteria, dust and skin cells to produce a sticky substance which glues the eye shut.

"Before you know it you have eye boogers in all their crusty, cruddy glory," Saranda added.

Americans also refer to eye boogers as "dream dust" and "sleep sand" - which, in Britain, would probably be names given to legal highs.
