The full explanation of how and why our fingers wrinkle in wet environments is still the subject of some debate. What we know is that the physiological mechanisms causing this phenomenon are the result of our veins constricting (vasoconstriction) in your hands and feet. One might notice this occurs even in warm water, when we otherwise would assume blood vessels should dilate instead of constrict.

This channel and Biographics are the BEST general channels on all of UA-cam. I don't say that lightly. Zero click bait, always right to the point, always interesting, and high quality filming/editing.
You guys have done such a great job!
Ah of course!! It's been the altered epidermal electrolyte homeostasis with its subsequent vasoconstriction that's been causing it all along! How didn't I see it earlier?
Bruh I understood like 2 words in that
I knew it was the nervous system, and it has been triggered by brain damage without the presence of water. But I still learned more! I am never disappointed by you guys.
That almost unnoticeable background music makes me think there's a doorbell or something ringing nearby (no not my own), or a ice cream car (which would not make sense, we have 40 cm of snow). I find it irritating.
half a metre of snow ?! where the f do you live, Antarctica?
LOL, the *Jehovah's Witnesses* made it through the snowstorm ! :P
I love this channel and where it's gone, but this music is an issue. I'm on call every weekend and I constantly think my phone's going off across the room until I realize it's the super-quiet music...
Feels like I'm in a shopping mall.
TAKE NOTE WHISTLER
Excellent video as always.
Thanks for explaining why we get all pruny!
OMG this explains even further why we get so dehydrated when swimming!
One of your best topics, thus far.
It took to the very end for me to understand that the wrinkling was "good"! Poor me! now I have to go back and listen again to see why it took me so long to get the information and process it correctly! Love the video's generally I understand the first time around! Keep them coming! Hope I can keep up!
When my toddler noticed this she announced she was shrinking. She wasn't wrong. Take that osmosis, from a two year old!
Toss ur baby off a fucking cliff like thanos. Lmao.
Wtf are these comments...
I love how clever children can be, sounds like you're gonna have a smarty pants on your hands! xD
@@Gahet She was very precocious. Now all grown up.😁
That’s an evolutionary adaption I would’ve like to have seen the event that selected for it.
“Wow, your fingers wrinkled when you grabbed that wet log to fight the saber toothed wolf giving you better grip... That’s a trait that will help humanity for countless generations starting with our children!”
Broken Eyes The ability to haul yourself out of water is pretty important to survival.
Good point. What killed all those whose hands didn't wrinkle, leaving only our wrinkle handed ancestors to be able to procreate?!
Exactly, just poking fun at the first “doing of it” of humanities great grand parents that resulted in all of us having this trait.... but yeah what ate the ones that didn’t? And where THAT go??!
Not everything has to be selected for. Could be wrinkling really is just a side effect of another useful adaptation and not a specific adaptation to a problem.
I once cycled 2 days straight in non-stop downpour (was cycling accross America). My hands were wet for so long, my ENTIRE HANDs were wrinkled more than I thought was physically possibe -- they looked like swollen brain coral, lol. Once they had a chance to dry out a bit the third day, they sort of went back to normal, but the skin became very sensitive and peeled away for WEEKS.
Sounds like you got Trench foot on your hands.
You mentioned it having to do with constriction which is what snakes do so could an anaconda cause fingers to wrinkle?
Take care and God loves you.
This lends more credence to my “We are Aquatic Apes” hypotheses.
At last the most important question ever asked has been answered
Heres a idea for a video -fractional reserve banking.... and why the hell the federal reserve gets to charge interest on printed money that tax payers take the risk on.
Whoa now, let's not go overboard with this whole truth thing alright buddy! Everything in moderation. /s
Jokes aside, I would love to read the comment section on that video. lol
@@Gahet sorry i dont like big banks alot my bad got worked up.
That how you get kick off UA-cam right there.
@@rasheedqe ?
@@dustintacohands1107 I think it's an unwritten rule of america that no one speaks of our system of imaginary money. The government doesn't like it.
Fascinating
Not to sound like a smartass but that was my hypothesis my entire life it just makes sense
It tells me that it's time to get out of the bath.
No never get some food settle in
Yeah that's how my mom did it when I was little. "Check your fingers! Are they raisins??? (Lol) okay time to get out!"
Your fingers have finger tips but your toes don't have toe tips. Yet, you can tip toe but not tip finger?!
Lol
😂
Those scientists that said there’s no disadvantage to grip with wrinkled skin must not scuba dive or work in the summer with leather gloves that get wet, when wrinkled my skin gets cut so much easier. When diving if you touch anything mildly sharp you get cut.
Superb!
Well I just learned why my fingers stopped wrinkling after my hands were crushed.
Incorrect word spoken at 2:43: The degree of wrinkling ... inducing (not, including) loss of digit volume ...
Interesting stuff
I want to watch a video of Simon Whistler reading the periodic table pf elements. Nothing else. Just, "Hydrogen, atomic number 1, atomic weight 1-4, valence electrons 1; helium..."
What happens is a scenario like in Harry Potter when a baby is left on someone's doorstep?
Seems to happen when it's cold, too.
If water originating from outside the body is the reason for wrinkles in the fingers, why then do I get them when wearing rubber gloves that are only exposing my fingers to sweat from my hands? It could still be a nervous system reasons but not sure it supports the idea that electrolyte imbalance causes it. Wouldn't the sweat then not have the same effect?
Got it.
Those alternate explanations sounded like they also involved osmosis as well.
Looked in the description for your podcast but there is none... 😫
I just noticed the subtle background music also. I thought I was hearing things.
I had heard about the increased grip in water years ago. Didn't know the science behind it though.
+1
every damn time i click on these vids i think im pulling up runescape back from years ago, its off key but its exaclty like the opening. A surprise to be sure but a welcome one.
Yet another thing I "learned" in school that turned out to be wrong, haha.
I'd heard of that debunking recently (well, past several decades) after I, too, had believed that immersion caused swelling (correlation taken as causation), but to this point I had not known the exact mechanism - or rather the details of the hypotheses proposed.
The current hypotheses do take into account the phenomena and fit into the current theory of physiology. So I can accept either explanation or a synthesis of both until some new evidence comes along.
I guess this might not be something observable in rats and mice...?
All I wanted was a quick and easy way to answer my nephew when he asks "Why do the fingers wrinkle?"...
Thank you, before you made this I was going to ask if you could find out if racing swimmers sweat in the water.
Gosh, after all these years the aquatic ape theory might have a point in their column.
When is the next podcast episode
Well human communities have always been next to water So evolving a way of holding things in water I kind of just forgot what to talk about I just think this is cool
If I take a bath in a high concentration of Epsom salts, I do not wrinkle, or as we say down south, get "pruney" (wrinkled like a prune). Even in very hot bath water for a long time.
I'd always assumed it was to increase grip, considering where it happens...
Didn't u already cover this a while back?
Grip
When we get rinkaly soon are skin can come off. Like dead boys that start to happen. And if their water left on are skin it can hirt. That's why we dry in between are tows 🦶 or else it will blood and be super painful
I thought everyone already knew this, but just to save you 5 minutes, it’s so you’ll have better grip underwater
I would argue that the relation to nerves is relatively unknown.
2013 is when this was actually figured out? That’s what I learned today.
I never understood how the osmosis thing would make any sense whatsoever. Fingers that wrinkle are smaller not bigger. So it made no sense.
Oh yeah
So.... if you get bitten by a snake would it be beneficial to put your hand in water?
I would like to see an eppisode about why we have to sleep.
Neat!
Question, Simon.... how did the saying "Until the Cows Come Home" come to be?
because cows are party animals n never make it back for curfew
alternatively, you let them out grazing n such all day n don't call them back until milking time in the morning.
Oh yea yea
wow who knew
Vasoconstriction meaning the wrinkles in your skin is bluebells
Whistley boi!
Everytime he says homeostasis, i keep thinking back to digimon, since that’s what a god calls itself
My fingers sometimes go wrinkly and I'm not even having a bath and then an hour or two later my fingers are not wrinkly anymore. My fingers keep doing this but there's no water involved if you have an explanation for this let me know... p.s I'm 32years old.
Wearing latex or rubber gloves for a long time will in itself leas to wrinkled fingertips. So I doubt it is an electrolyte imbalance.
Ok so whats the answer in English??
if you work on braking systems and exposed your hands to brake fluid, they will wrinkle instantly on contact with water
No dearth of Hiskeys is there??
Bro my entire hand gets so wrinkly it hurts to close my fist...
...but, why do so many people slip in the bath tub/shower?
Never dropped the soap ( ͡° ͜ʖ ͡°)?
Ciao a tutti
The reason for wrinkling fingers is because you can swim much better with all the ridges on your fingers and toes because they have better "friction" in water... also the grip study was later proven wrong.
I'm guessing Susie Dent won't care a bit about this explanation.
I was told as a kid. The wrinkling was caused, because all the oil in your fingers was gone.
*Because water isn’t wet.*
Heyy
Why do my fingertips wrinkle when it's very cold? (but not wet)
To get more grip under water. Just saved you some time :)
I was today years old when I found out
I just had to click on that thumbnail.
Anybody else get shivers just thinking of rubbing wrinkled fingers together ☠️ ughh it’s like nails on a chalkboard
I love “knowing” something, only to find out the earth is round.
*Find I was totally wrong.
I am not a flat earther.
Why is Benjamin Franklin on the $100 bill????
I thought that finger wrinkling was just because of the oils on your hand
It’s so you can grip in water there you go saved you 5 mins
🛑🚨Wrong! Completely wrong. Our fingers and toes wrinkle because our body is adapting to be ready for activity under water. The wrinkly skin offers better grip in a submersed environment.
what? It’s not hard to actually prove or disprove the electrolyte theory, you just make a water solution with the right balance of electrolytes and see if a hand wrinkles in it...something’s fishy about that study/fact
Frinkles
johny sins with beard :D
Where does the phrase in-law come from? i.e. Sister in-law
Not entirely sure, but I think it has to do with "in the eye of the law" because marriage is a legal contract!
Still doesn't explain why skin on other parts of the body don't wrinkle.
It does when you age, but I can't see the advantage, in that.
@@christelheadington1136 No! That's different wrinkling. That's because of old age and it's irreversible, mostly due to cell death. When exposed to water is different. It's temporary, quick and doesn't involve apoptosis.
@@rojalrijal6529 I knew that, I was joking.
@@christelheadington1136 Aah! Okay! It's just that I've seen enough stupidity that I don't even consider something to be a joke anymore.
The Internet has ruined me. (Kidding.)
First
Because you in the shower too long pulling one out
Who here knows what language he is speaking?
that was too fast.
It would have been nice to be broken down more simply and in plain English. This felt rushed and complicated.
Wrong
I love this sht
Love the videos guys but i must admit, often times when you do biological content i struggle with the heavy use of jargon/terminology.
Such a long explanation
it's because theyre wet lol
Why add real to the title? Stop being that UA-cam channel when you're actually much better quality than that. Fire your title making person post haste!
Nice to see the phrase "post haste" being used more often!
Because if you actually research this, you will find MANY otherwise reputable sources giving the popular misconception answer.
@@TodayIFoundOut right, but if everyone claims THEIR history is "the real, true etc" aren't they playing into Trumps fake news hand?
@@zicada7661 lol what
