- Have you ever thought "Why do my fingers and toes get all wrinkly when put in water for a long time?" Well we have the answer for you with Dr. Moo! This reaction to water still puzzles scientists to this day, but what are the leading theories? We break it all down right here!

I can barely hear her talk over the techno music. I just aged 10 years
Well, that is nice to know... That no one knows.
Well, knowing which answers are wrong can sometimes help us learn where to look to find the ones which are right.
Yes, that's how science works, we do research and learn some things. In this case we have learned how and when it doesn't function but not the why. One day we may find the answer by hypothesizing and observation.
Kyle is MIA, He returned to Asgard coz it's Corona Virus-free there
his new channel is Kyle Hill breh, come thru

So no more kyle here? Time to unsubscribe
Yep, "creative differences"
I enjoy the art. Props to who ever put the time and effort into drawing all this
Finally got Doc Moo to voice over! Thanks Doc. The show isn't the same when it's just written word and a repeating track in the foreground.
I was seriously to the point of volunteering to do a voice over on the finished animation so they'd at least be more interactive lol
what about it cuts bloodflow lower to avoid temperature loss which is greatly increased when in contact with water?
Then why only hands and foot? It's not that large area of a human body
@@ilyazakharchenko8495 Those are the areas of the highest heat loss in the body
@@theStumblinbear that's actually not true. The amount of heat radiated away through the skin depends on the surface area!
I don't think that pruney fingers have anything to do with preventing heat loss, or that the reaction evolved for that purpose.
@@ilyazakharchenko8495 its less of a factor of area than access to blood which transports heat inside the body, the hands especially have lots of blood to support their advanced manipulative functions, also in winter it takes just to heat up groin, neck, head, feet and hands to remain warm, other parts are less important
A good way to test this would be to wrap someone's hand in something that's as thermally conductive as water but not wet, and also to put someone's hand in body temp water for a while. If they get pruny with the first and not the second, then we know it's heat loss. If they get pruny with the second and not the first, we know it's only due to it being water. If they get pruny with both, then they are either both factors or there's something else going on.
Dr. Moo???
we miss you!!!
take over the lead of because science and turn it into because space
I'm sure someone's said it but, could it be the body's attempt to retain heat while in water for a prolonged time? Hands and feet act as great radiators, less blood flow means less heat loss
That's exactly what I was thinking since it's a nerve...reflex? Best way to put it with being half asleep. But it would make sense that even from an evolutionary point. Could also be a way for our body to slightly numb the area due to the lowered blood flow to help aid us in getting out of the water by any means.
@@KissMeFatality numbing is an interesting thought. People with nerve damage wouldn't need the numbing because they already lack feeling, so their body wouldn't make itself prune.
Didn't even think of that
What I tought also. Swimming mode activated.
No, it makes our hands and feet more grippie
It seems relatively obvious that as the body senses a change in temperature like a wet environment which dissipates heat quickly the body causes the vascular constriction to try and control temperature by pulling the blood away from the extremities like the hands and feet and as you said this causes them to in essence deflate and prune. The reason an extremity that has had nerve damage doesn't do this is because of the nerve damage so those blood vessels don't get the signal to constrict. It's a common automatic response to thermal variation. Your fingers don't prune just at the sight of water they actually need to go in it, and should prune more in colder water in a far shorter period of time than warm or hot water. This reaction to thermal loss is so intense that a person suffering from hypothermia will constrict all extremities to the point that they can't use their arms and legs as they are all pulled into a small ball to try and keep the core temperature high enough to prevent death. So at that point the entire human has in essence pruned up. Only after being warmed back up will the person regain use of the extremities just as the blood returns to the fingertips to re inflate with blood. Why does it have to be anything more than that?
Title: Why Do Our Fingers Get Wrinkled in Water?
Answer: TLDR dunno
By design.
I love the science lady's voice. Now get some more/new music and you have yourselves a channel with basic functions.
That's Dr. Moo
You should do “Why doesn’t my crush love me back” next episode
No explanations 😭😭😭
With science
Because science
You will live single.....
Because science
Because of the pressure... ;)
So do other primates have wrinkled fingers and toes when submerged?
I thing that the music is a little too loud
I definitely think the grip theory holds the most water *rimshot*
Vasoconstriction tied to heat loss? A way for the body to protect itself?
then the damaged people they spoke about, should manifest wrinkles too.
so...nope.
@@Xhemnar Think about it, on the people with nerve damage their body may be trying to send the signal to reduce blood flow, but it's not getting there. So this could be a valid reason.
When you are cold you don't get wrinkles all over your body. Cause your body can restrict blood flow without them.
@@patrikburda true, when cold you "perk up". If the reason was to avoid temperature loss i think we would see more pruning across our bodies.
I like to imagine that they get wrinkled because if you're swimming in the ocean or something, they become wrinkled so that you can grip things easier.
for example if you drop your keys in a river, you can grab them without them slipping at all
I was gone for over a year, and now Kyle's gone
His new channel is called 'Kyle Hill'
Doc Moo! I miss her! Wish we could see more of her.
The Audio in these green videos need to be processed, please they are painful to watch due to the audio being all weird.
I refuse to watch this video if my favorite person isn’t doing the talking :(
Several others commented on it but I am surprised that hypothermic protection wasn't explored as a possible explanation. It does make sense..... I think
The way I see it is cold if the blood vessels are restricted that means your body is pulling blood to the core of your body and the extremities restricts blood flow to keep internal organs at temp
It could be the body trying to protect core temperature. By restricting blood flow to the fingers and toes.
Thank you for this episode. My kids ask me about this EVERY SINGLE TIME they get a bath.
My theory is the body is trying to conserve heat.
Maybe is just to reduce the lost of body heat when we get wet... with vasoconstriction we have less blood flow therefore less heat lost to environment
Then why doesn’t it happen when we get cold? Why does it only happen to the palms of our hands and souls of our feet and not the entire extremity or even our entire body?
This was surprisingly interesting.
It could be a response to being in the water so long the body starts to gear itself up for going into shock or hypothermia as evolutionary there would be no reason to be in water that long unless you were in trouble, so the body starts to cause vasoconstriction to conserve body heat and improve blood flow to the organs and brain.
was a nice video... i really liked the idea of increased grip... at least now i know my hands are not drinking water :D
My assumption would be thermoregulation… the less spread out ur blood is the slower u lose heat and water is great at heat transfer
I love this serie make more videos as this
So the wrinkles are caused by blood vessels constricting. Blood vessels also constrict when experiencing hypothermia, in order to keep body heat in the core. Water is an incredible heat sink, having a very high specific heat. That's why climates along the cost are also so much more mild than nearby inland climates. Seems to me that when we come in contact with water, our blood vessels constrict to prevent losing too much body heat to the water, and the wrinkles are just a side effect.
I thought it was the same reason your body restricts blood flow to your extremities when your in cold temperatures, to reduce heat transfer and keep your core temperature regulated. Not sure why I thought that, it just made sense to me.
Wasn't this exact topic covered on this channel a year or two ago?
There's a typo in the text.
Can you find it?
Hint: it's at 1:02
"Orautomatic" instead of "or automatic"
@@Mark-xg3zn an Orautomatic response is actually when someone reacts to a lack of space.
@@BamBam0141 I dont see that definition anywhere
I mean.. someone missed the space key.
@@Adloquiem its a joke lol the "Orautomatic response" is our response to pointing out the lack of a space between "or" and "automatic".
Reaction to a lack of space. Lol
Please do an episode on Stark nanotechnology
Honestly, I think it might have something with termal regulation, and being evolutionary left-over, as usually in the wild water is way to cool down but too long exposure might cause loss of too much temperature so lowering blood pressure in the hands and feet which are bodies strongest terrmal exchange areas with the environment, might be a way to prevent it
I agree also people with neve damage won't feel the temp change when the water is evaporating off the skin so there for no restrictions form evaporative cooling
@@kevadraco well i'm saying it might be evolutionary left-over of something liek that due to fact it also reacts the same way even to warm water, which shouldn't be much of a threat to lossing temperature, but is also much harder thing to encounter in nature
@@LilithLonelyHeart yes but warm water has a higher evaporation rate so still it could be the body trying to conserve heat so it would try to restrict the flow of blood as a preventive measure
I mean your body can restrict blood flow even without you having wrinkles all over your body. When you are exposed to low temperatures your hands and feet feel cold cause they are (because your body just restricted blood flow keeping it in your torso for vital organs).
@@patrikburda yes it does but the difference in water is pressure air pressure and water pressure are two different things also to counteract the warm water thing your body temp is 98.6 if you put your hand in 100 degree water the heat would transfer to your hand then as the water cools your hand remains at 100 degrees therefore heat starts the other way therefore your body will restrict blood vessels then the pressure of the water would push your skin in if someone has nerve damage there body could not respond the same till cool blood cools the core of there body
What if it has something to do with our skin feeling colder when pulled out of the water due to evaporative cooling and such so our body reduces blood flow to maintain body temperature?
YOUR the best
Maybe it’s because to safe body heat. Water absorbs more heat than air, so by decreasing the pump in the veins, less blood (and therefore less body heat) gets absorbed by the water. But this is just a thought of me.
DR MOO!!!!
Gripping marbles, not likely to be a benefit....but gripping fish in the water, probably very helpful. Also fish could be eaten raw, which be be a natural way that we would have ate food we were meant to eat. Fish also have Omega and that genetically is a must have for us isn't it?
I always thought that wrinkled fingers might slightly improve our abilty to swim, because of the increased surfacearea
Just to grab things underwater better. God is a master of his work.
Could it be a form of preserving body heat? the only reason why im asking is because the body does something similar in hypothermia pull blood away from the extremities to keep the core warm. I know this is unlikely because i doubt we loose much or any body heat from our hands in water but would your hands do something similar if it is related to hypothermia?
Kyle is in his secret lair monitoring the spread of the bat virus he released last year when we figured out he's a supervillain.
And that secret lair is called 'The Facility'.
(Kyle left this channel and his new channel is called Kyle Hill. 'The Facility' is a reference to the videos there. )
Anonymous RS thanks!
Note this could have been the shortest video in the first 8 seconds.
"Why do our fingers get wrinkled". Answer: We don't know. End video. lol
in my holiday homework, there is a question that is 'Why does the skin of your finger shrink when you wash clothes for a long time?' and I watched this and now I am confused because according to the chapters I have read I am supposed to answer this 'Soap solution is a hypertonic solution, During the washing of clothes, exosmosis takes place in the skin cells. This leads to shrinkage of skin over the fingers while washing clothes for a long time.' now what should I do?
I heard this can also be dangerous and fatal. If your body is in water for too long you skin becomes damaged which can kill you. There is a photo of a girl trapped neck under water. She died later.
Mabey the reason when your fingers and toes get wrinkly when wet for long periods of time is to send the blood to vital parts of the body. When exposed to cold air or very cold water for a long period of time your fingers and toes become numb because lack of blood flowing in them. There is a similarities between both bodily functions In my opinion
Must there always be a "why"? Not every single molecule in our body is perfectly constructed.
What if it has to do with maintaining body heat in water? I mean why would we constrict or blood vessels when exposed to water? What if the wrinkly skin is just a side effect to the main reason we have this response.
Heat retention in the extremities, duh.
Wow. Primaryschool science... or middle school depending on country
Are you being sarcastic? It's a neat subject.
@@JasonWW2000 it is a neet subject. It's also something you learn in school. Evolution rocks. I'm mostly being sardonic.
@@kirstyshadowdancer5095 You learn what in school? The reason for this phenomenon is not known so school can only tell you it happens. We can figure that part out by ourselves. So what does school say about it?
@@JasonWW2000
Well when our meat oars gets wrinkled it increases the surface area and makes it easier to swim. Maybe that’s an explanation?
I stay very hydrated, and my fingers still get wrinkly in water.
So, perhaps it happening because of dehydration, is not correct.
May it be to decrease temperature loss from body
Alright then here's a scientific question for ya. How powerful is Blankman's superhero gadgets and equipment?
Is it easier to swim with wrinkled hands and feet?
Our body does that just so we can grap things underwater more easily, right ?
I always assumed it was our bodies signal it's time to get dry for a bit. I'm pretty dumb tho so don't take my word for it
Hi kyle ,How strong is doomsday(krypton) and is it possible to turn someone into doomsday like in krypton the series??
Kyle is no longer on Because Sciense. He left to start his own channel called "Kyle Hill".
Okay, but why are the subtitles in Dutch?
I only get out of the shower when my fingers are wrinkled.
It’s a recent evolutionary response designed to save time and water. When you’re wrinkled to buggery it’s time to finish your shower.
0:59 Hey Doc, you forgot to space out two words.
It happens to increase grip under water. Remember, we are aquatic apes.
Next time just watch the video before blabbing out garbage, thanks
H Kr you don’t seem to understand the difference between above water using marbles and below water on natural textures. Go spend some time diving in warm water for conchs. You’ll see what happens as your hands adjust to underwater.
Im guessing it's for grip
Why not?
Can magnets can stop a bullet and how much magnetic force or electronic magnetic force to stop in 1 sec or more time and love science and your channel
Easy.
Bang - - - - - -> |||||||| Bullet Stopped!
Do other primates have the same response?
Why not mention that we still SWEAT underwater? If we're losing that much water from sweating, then it's natural for our skin to shrivel up in order to prevent more water-loss.
mine don't and its really weird
Nice video, but the music is too too loud. Better no music or different kind and quieter ;)
This is a video that did not need to be made
Here’s a better question
Why am I watching this at 3AM?
2:34 am... you're not alone on this one...
Kyle has his own channel. Everyone go there.
For those who were wondering what it is called, the channel name is Kyle Hill.
I find all this amusing
I need this
John Sushi do you though? I mean do you really need this?
Jesse Hudgins I mean I could live without this. But like I need this
I like a little wrinkle dinkle myself
My fingers get wrinkled once they touch the water
nice
Let's have science explain the sudden stop to texting on dating apps when a conversation is going well.
That's actually an interesting psychological topic to explore
Where is kyle?
Kyle is at the 'Facility'! .... meaning he left to start his own channel a while back. His new channel is called "Kyle Hill".
So he left because science?
@@fahimtoufiqulislam9264 Yes. There were some areas of the show that him and Nerdist (the company behind Because Science) couldn't come to an agreement on so he left to start his own science channel. Because Science posted a video announcement about him leaving a while back.
I didn't know. Man this makes me sad

Grippie
Get that other girl back with the deep voice!
I will answer this all for the world. I matter how much water I drink, my hands get wrinkled SUPER fast (it surprises anyone I show this to). It DOES in fact increase grip on rocks and such HOWEVER they become much more susceptible to cuts and splinters!!! So it makes sense for hands to remain smooth and tougher in their dry state to deal with wood or sharp objects.
:o
No Kyle. No luv. I'm out.
Go to his new channel "Kyle Hill"
