Your home is filled with thousands of species of insects, bacteria and fungi. And even if you assume that most live in your bathroom, the dirtiest place in your home is not your toilet. It's your own body. But it turns out that having a lot of biodiversity at home helps you stay healthy.
The following is a transcript of the video.
Look at it, your house is dirty.
It is filled with dead skin cells, dust ….
… and about 200,000 different species of insects, bacteria and fungi.
Now, it is tempting to assume that most of them live in your restroom.
After all, that's where … you know.
But here is the thing.
The dirtiest place in your home is not your toilet.
It's actually you.
Domestic microbes hide in the most unlikely places.
Take a heat-loving bacteria called Thermus aquaticus.
These guys can only be found in two environments:
Hot geysers like Old Faithful in Yellowstone …
… and your water heater.
Another example is the Penicillium mushroom.
They slip into your air conditioner from the outside.
And when you turn on the air conditioner, their spores spread in the house and are known to cause allergies in 2 to 6% of people.
So, when you notice a funny musty smell coming from your air conditioner, it's probably the mushroom. & # 39;
But before you start looking at your central air with suspicion, think about this:
You spill germs all over your body every time you shower.
It turns out that billions of organisms live in your shower head …
… .Piled on top of each other in a thick slime layer of half a millimeter.
But this is not necessarily a problem.
The researchers found that one type of mycobacterium in the shower actually increased serotonin levels.
It's a neurotransmitter thought to reduce stress and increase happiness.
And when these wandering mycobacteria land on you …
… they join tens of thousands of other species of microbes living in the dirtiest places: your body.
Like Corynebacteria – microbes that give your armpits that stinky smell …
… and simultaneously fight harmful pathogens like E. Coli
Meanwhile, 300 to 500 species of microbes colonize your gut …
… and they are thought to play a role in maintaining your immune system, your digestive system and even your mental health.
In the category of non-bacterial microbes …
… you have guests like microscopic mites that live on your face …
… and the mold that colonizes your toes.
And although their idea can give you chills …
… microbes like these protect you.
You see, the number of harmless microbial species in the world is 1,000 billion times higher than that of the harmful species.
In fact, less than 000000001% of microbial species are responsible for almost all infectious diseases in the world.
And all these harmless bacteria crawling on your skin mean less space and resources for pathogens, like antibiotic-resistant microbes.
Which also means that they have fewer opportunities to take over and make you sick.
So, even in case of antibiotic failure, all these other creeping microbes might protect you.
In a way,
… you must be a little dirty to stay healthy.
But a full disclosure: this is not an excuse to swear from your shower.
In addition, you do not want to miss this beneficial mycobacterium!
