The good news is these teeny tiny organisms don't actually chew on our arms and legs, only eat dead skin cells

First off, fair warning: if you're planning on sleeping tonight – or any other night, for that matter – you might want to skip this video. Otherwise, chances are that you'll never again want to lie down in your otherwise perfectly comfy bed.

The video below tells the tale of dust mites, which are basically teeny tiny organisms that live all around us. Seeing how they only measure about 0.3 millimeters (0.011 inches) in length, they are pretty much invisible to the naked eye.

This might come as a bit of a shock to some people, but as it turns out, the one thing that dust mites find utterly irresistible is human skin. Now don't go running for the hills just yet.

True, dust mites like to eat human skin. Still, this does not mean that they chew on our arms and legs when we're not watching. Thus, it's dead skin cells that fall off our bodies that dust mites like to feast on whenever they get the chance.

Seeing how many of the 1 million skin cells our bodies get rid of on a daily basis end up in our beds, dust mites have taken quite a fancy to setting up camp in our mattresses and pillows. In fact, it is estimated that the average mattress is home to about 100,000 such organisms.

Dust mites themselves are not a threat to humans. Still, some of the enzymes they produce when digesting food and that are excreted together with the leftovers can cause allergic reactions in humans.
