Disturbing simulation showing how microscopic bugs live and poop on your face is leaving viewers with 'new fear unlocked'

There are some truly disgusting health facts out there. Like the fact you produce the equivalent of four beers of phlegm a day, the average belly button contains 50 different species, and we shed around 30,000 dead skin cells every minute.

We've all heard the gross statistics about how gross our phone screens and keyboards are, but trust us, the filthy facts don't end there. The human body is its own massive petri dish of bacteria, and while we know it's all part of battling off diseases with our white blood cells, too much and certain types are bad for you.

You might not want to think about it, but a new simulation from Zack D. Films shows a grim underside of the human body's health. In the video, we're told how tiny mites live in the pores on our faces and crawl around over our skin.

Worse than this, the video explains how they feed on the natural oils that skin produces but have no way to expel the 'waste'. This means they expand with feces throughout their lives, and when they die, it's expelled back onto your skin.

Your immune system reacts to this and causes the skin to swell and go red. This can lead to irritation, with Zack D. suggesting that if your skin is red, it could be due to this.

There are obviously other reasons your skin could be irritated, but in the comments, people lost their minds over this gross reveal.

One concerned person wrote: "New fear unlocked: you could be a potential toilet for bugs."

Another added: "'Just one more short before bed' 😂 The short:💀😳."

A third concluded: "Thanks Zach. Now I know that there is exploding poop blobs on my face."

Demodex mites are tiny eight-legged parasites that can be found living in your hair follicles and oil glands on your face, neck, or chest. They're generally harmless and can actually help your body by removing dead skin cells, but it's only when you get a buildup of them that you're in danger.

If you weren't already concerned, they can also affect your eyes, leading to irritation and potential loss of eyelashes.

Eggs hatch within 3 to 4 days of being laid, reach adulthood after a week, and tend to live for two weeks. Scrubbing likely won't remove them, although there are treatments if you're faced with an outbreak.

Those who face an extended period of redness should go and seek a doctor, who'll typically prescribe metronidazole to wipe out those minuscule mites.

Now if you'll excuse us, we're off to have a good wash in the shower.
