Is Dust Mostly Dead Skin?

- People claim that 70-80% of household dust is dead skin, but is it true?
Thanks to Google for sponsoring this video! Learn more about Search here: www.google.com/search/howsear...
Special thanks to J.M.E.H van Bronswijk, author of 'House Dust Biology'. We exchanged emails to make sure I got my facts straight for this video. Below is an excerpt from her email to me, responding to my claims that start with a dash:
- Around half of airborne dust particles under 100um are skin scales
This is true for climates, regions and seasons where people live mostly indoors.
The 1 to 2 g of skin scales shed each 24 hours will end up in places where people are present (and rub their skin or have textile moving over the skin).
You can also look at it from a different angle: What else has the same size and could contribute? That will usually be pollen from outdoor sources, also depending on season, region and climate, as well as the ventilation regime of the building.
However, taken as the median value over a whole year, I consider your statement correct for regions with a temperate climate.
- 53% of dust particles vacuumed from a mattress were found to be skin scales
It depends a little on the type of mattress. For polyether mattresses the amount may even be larger.
For mattresses made of natural material it could be less since the mattress-material will also give off small particles.
- larger particles consist mostly of fibers, eg. cotton, paper, wool, synthetics
That's true .. including bread crumbs ..... 🙂
- skin scales seem to form a larger fraction of dust where we spend more time, e.g. in or near bed.
..... and on the couch used to view television or be active in gaming.
It has to do with the constant production of skin scales over the 24 hours.
- skin scales form a smaller fraction of dust if there are significant other sources, e.g. carpeting, dirt from outside etc.
Yes, everyting you walk on with your shoes or that recieves dirt from the outside with other means, will have a lessr percentage of human skin scales.
However, do not forget the skin scales of pets that will also be an active allergen for many people, and a food source for house dust mites.

"This video is sponsored by google" That is the weirdest thing I've ever heard.
ikr
i was expecting skillshare or nord vpn, that was a surprise
felt very uncomfortable and confused
Google work in the mysterious way 🤔
its so confusion becouse i watch this video on google
"This video was sponsored by Google" is literally the most elite thing a youtuber can say.
Getting a sponsorship from Google while on a Google platform (and making ad revenue on that). He basically just got a fat pay raise from his boss haha! Absolutely legendary
@@hectichive889 I was just thinking that, it's not even a sponsorship technically, he's just getting a paycheck with some extra steps lmao
It's also selling your soul to the devil.
....and the most EVIL.
I for one welcome our google overlords.... Interesting how this vid got so many views
"If dust is mostly dead skin, then why do abandoned buildings get so dusty overtime" sounds like a amazingly terrifying story
or sounds like that other "30%" of dust just over long periods of time
I just stumbled upon this comment while the video was playing at the exact time derek said that
Cracks gaps
There's also some dust in space
blows in..when we shower loose cells go town the drain
"Is dust mostly dead skin?"
People allergic to dust: *Maybe I am allergic to myself.*
is dead people still alergic or-
autoimmune disease 😔
ACHOO-*flat line*
lol
fr though, as someone allergic to dust I can tell you it's not the dead skin, it's the dust mites who eat your dead skin
you are allergic to your deadself leave it behind
I think the craziest thing about this video, is the fact Google are actually paying people to advertise Google... who is their target audience? The 10 people who use Bing?
Public awareness and sentiment in the context of ongoing tech antitrust hearings, maybe?
Geez people. I was only making a joke. I don't actually care what search engine you use lol.
@@TheJollyGamerJoe haha, no I want to tell you what search engine I use because the Internet people must know

@@joethompson9124 Google gives best results tho.
edit: minor tweak so the comment doesn't look menacing
"that's as many stars as there are in the Milky Way Galaxy", which relates one number I have no way of really understanding to another number I have no way of really understanding.
Try thinking how much dust is in the milky way
I think he used Numbers of named stars
Maybe it would help if you think about the number of sand grains on a beach.
what if the stars in our galaxy are the dead skin cells of "gods" and our dead skin cellls are galaxie omge
try thinking 30x the entire human population. thinking like that is pretty nice actually, everyone can have their own galactic empire
I never realised how meaningful the term "ashes to ahses, dust to dust" was until now. Being carbon based lifeforms and returning to dust once again after all we know including ourselves was created from stardust.
It's not that meaningful, it has a real origin.

I was at a primary school and had to climb up on a ladder to clean out the dust filters in the projector mounted high on the ceiling of the school hall. Predictably, there was a thick layer of dust, probably building up over three or four years since whenever the last time the projector needed servicing. The dust was a pale shade of pink to match the bright red school jumpers and cardigans that the school used for its uniform.

It's more like Google is a good jumping off point.
Lots of people use it just like he said; typing in the answer they want as the query, taking the results from it and going no further. The more responsible thing to do is use the results to look further into your query using your own research tools or at the very least look for verified sources.
@@crushermach3263 yeah, I was expecting him to use Google Scholar or at least show that he found the experts he wants to contact through Google, though
@@crushermach3263 It's so frustrating too. If those people would just prepend their query with "is" they would give results with more critical discussion.

Well, to be fair this book can be found on Google, so...
I think Google wanted a video on Veritasium, and so a topic that can be resolved with Google searches was used. This video was very informative as to how one should research on the Internet, instead of searching for our own biases.

What I take from that graph is that dust across all sizes is mostly composed of cotton fibers. Sure, half of the smallest particles are dead skin, but over 100 um they only amount up to 20% (or less) of the dust.
I guess it depends on what proportion of dust is small and what proportion is large.
But can we draw different conclusions regarding mass vs. size? Dead skin cells are most likely denser, so they dont contribute to the size of the dust in your vacuum, probably not even colour or look of it, but they should contribute to the weight of your vacuum.
I was going to make the same complaint, but he was clear about it shortly after

I’m grateful for it, it’s much better than Ask Jeeves.
This was a very well put together presentation. Thank you so much!
What fascinates me is that my bedsheets are various bright colours, as are my curtains and carpets, my skin is ostensibly pink, and I'm constantly dropping various crumbs of foodstuff on the floor (particularly crisps and bread, which are sort of yellowy) but when I empty the vacuum cleaner, the dust is *always* the same light grey colour, like the surface of the moon. Dull, lifeless, and grey.
that's because scientists haven't figured out the other 50% but it is rumored to be flakes of our soul. Most people have grey souls. Mine happens to be purple and green. my dust ball comes out tie-dye
As far as I know, skin is actually that grayish translucent color, what gives it its pink color is the blood underneath, diffusing the light that gets through.
Skin is colorless and grey. The color you see is the blood in your arteries and veins. Microfibers are actually quite transparent individually. As for chips and bread, surely most of it turns into large chunks which are swept up or cleaned by something that isn't the vaccuum?
@@zachrabaznaz7687 so people with brown skin have brown blood or?
@@fictionmeister that's extra melanin (which just makes it darker). Try peeling a bit of skin layer by layer (don't ask why I know that) and it slowly gets redder and redder as you go down.

Great comments. I found this more about people buying in to false information than about dust, in general. I see this constantly. All that has to happen is for a social media influencer, celebrity or politician to make a false claim and soon you'll have everyone on that bandwagon.

So the answer wasnt actually in Google, it was in a book.

He had to do a lot of research online before eventually finding the book though
OrangeC7, He only found the book after he personally talked to experts and they told him to read it. Google gave him nothing but misinformation and false claims.
I'm pretty sure Google has that book on record since its almost 40 years old.
But that's a pretty funny point. Considering most of the info he gained was from google, but the book did have some key insights you could pluck out.

How can he NOT mention that Google has a censorship filter, and therefore you won't get accurate results except for topics that are entirely uncontroversial? The ONLY reason Veritasium isn't being / hasn't been censored is because he toes their line -- as soon as he doesn't, Veritasium will be censored too. That's why they have to resort to this kind of advertising - they're essentially saying, "Hey, use us, cuz we're big, don't mind our censorship of everyone who doesn't agree with our agenda." Veritasium somehow hasn't noticed this?

Ok, here's a question I've always wondered, and maybe you can tackle it in a future episode: If the geological model of the Earth is correct, and you can look through the past as layers of rock and earth... where does all the material that makes up these layers of rock and earth actually come from? How does the past actually get buried over time? Is it from layers of dust? An accumulation of particles from micrometeorites? Or from some other source? And is the Earth actually getting larger over time, as it accumulates successive layers of "time"?
What you're missing out is that everything comes from under and goes back within. Basically everything we are made of has already been a part of earth for ages, and when we perish it goes back in to be reused over time, howsoever long.
There is no 'new' matter that is coming that would stack up on earth. (except probably some space stuff)
Sounds like he'sasking about sediment layers. To which the main answer would be erosion.
New layers of sediment are mostly formed in the ocean. Sand and clay are transported there by rivers, millions tons per year, for millions of years. The highs (hills and mountains) are eroded and the material fills up the lows (oceans).
After some very long time, sediment transforms into solid rock, and then eventually some huge tectonic plate movement shifts the entire Earth's crust and brings the young rocks to the surface. The process never stops: these rocks are brought down to sand and dust which go to the ocean and form new rocks
@@angaj thats one of the important examples of how perfect nature is
To be more clear, crust is eventually subducted back into the mantle, melted down and, over millions and millions of years, erupted back onto the surface. This process does slow down over time as radioactive isotopes decay (thus contributing less heat) and the core of the planet cools, but there are no significant sources of extra material to add to the planet. Biological material is subject to these same processes (fossilization and the like) but more often is broken down and recycled by the biological processes of other organisms, which are limited in growth by the food resources and environmental conditions available to them. New matter cannot be created and there's simply not enough stuff falling from space to appreciably add mass to the planet.

it's possible that thanos snapping is speeding up the aging process, so fast that you just disintegrate to dust.
@@tylko4170 mm interesting. If there were no bacteria/microorganisms or worms etc then animals wouldn't break down into dust for almost an incomprehendable.amount of time. Would.look so similar. Maybe it speess up things long enough that the atoms unbind whatever time that is
"Is dust 2 t sided". Yes. Yes it is.

If the the dust particles are realising from us then why our fingerprints won't changes??
Better question: "What needs to change to make Dust 2 balanced?". I mean the map is already a 4-square design, that comes close too being symmetrical in terms of distance to A and B from the spawn sites (but it's not exactly equal, because the CTs need to get to the sites a little faster).
Wowzers. Great episode!
Wow.... Finally my search about dust....gave me some knowledge 😀
At start, I was wondering about why would Google sponsor a video, but later I realised that its not promoting Google search, but rather how to use it efficiently.
Yup, that was the point. And I pitched them this topic.
@@veritasium I wish you pitched it to DuckDuckGo instead
And google approached you! Wow that's a flex

I really thought you were going to end that sentence about 5 words sooner.
There's also a considerable amount of intellectual nihilism and conspiratorial ideation on the web as well. Particularly in comment sections.
you said that as if its smth shocking
@@Markle2k Can you elaborate?
Are you going to end that man's whole sentences for him? o.O
@@Markle2k What did you drink?
I finally found the perfect video, thanks!
Don't let the Google sponsorship distract you from the fact that your walking around in a cloud of microbial soup
Mmmm soup

@@nathanberrigan9839 I just did some rough calculations, and during the pandemic and working from home, I'm estimating about ... 80% of my time in bed... :|

I feel like my mom showed me this channel when I was born and I never stopped watching
The problem of the origin of the dust occupied me for many years. I lived in different houses, with the same furniture and comparable other factors, but there was a huge difference in the rate of dust accumulation. Also, there was no significant difference between rooms that remained empty versus those that I sat in all the time. I wondered if a lot of it came from dead wall paint rather than dead skin. The question remains.
