If the finger wrinkles after wet, then why does my back not wrinkle? I immigrated and I do not have a wrinkly back, but it's wet. Neither is the toilet plug wrinkly, but I clean Trump's toilet every day
So I have a theory I'm gonna posit here now @scishow or for any numbskull reading this and bothering to give me the credibality of an average guy ... We get wrinkled fingers ... Also when sweating ... Noticed it in jiu jitsu and also noticed that gave me the ability to grip another fellow sweaty primate I'm rolling w ... So that's another factor that undeniably is a benefit in combat that some disntant progenitor 🙄 over for advantageously having when needed
I just took a long shower and got really pruny hand but for some reason I feel as if pruned hand are fascinating to look at and stuff I feel as if I could stare at pruned hands for hours just me that does this?
everyone always says wrinkled fingers and toes, but actually your palms and soles of your feet aldo wrinkle and so the theory that it helps us grip better would ve useless without considering the palms and soles of the feet because toes alone would not help you grip a wet surface because the rest of your foot would still slide on wet surfaces thats why the soles of the feet also wrinkle this allows us to get a better grip all the way wround and this also applies to the palms because we use our palms just as much as our fingers to grip objects. its a cool theory and it seems to hold up given the evidence. its just one of our amazing features that went unnoticed for a long time.
Over the summer, I swam over 3 hours a day. My fingers never got wrinkly throughout the whole summer. They also never got wrinkly when I took showers.
I came back after the 2 week break for the start of the winter season and the very first practice my fingers got wrinkly while swimming and during the break, in showers.
I don't know why, but I guess my skin adapted to my swimming somehow? I have no nerve damage. I know for sure that my fingers weren't wrinkly over the summer. I immediately notice if they are because it's such a weird feeling.
My sisters fingers didn't wrinkle at all and we were both in the pool for the same time. They used to wrinkle but at some point they stopped and now no matter how long shes in water they don't. She can still feel her fingers and she's never had surgery on them so what's going on?
Hel00Everyone...First--of all, I would like to add that ♦♦♦♦maxelder argan product ( w---- nyarganoil---c) is excellent!..♦♦♦♦The price is reasonable and the product w.o.r.k.s like a charm. The first day I used it, I was highly impressed as it really moisturized the wrinkles and provides an excellent shield.
OMG THIS HOST DRIVES ME NUTS he has those stupid earlobe stretcher things and that dumbass beard what the hell is that thing anyway and ... oh, that's right. It's Michael. We're only allowed to rip Olivia apart for equally weird personal oddities.
BTW, I'm kidding. I like ya, Michael. You keep being your weird self, it's charming -- just like when Olivia does it. :-)
SciShow, but my biology textbook says, "When you go swimming or soak in the bathtub for a long time, the dead cells on your skin's surface absorb water and swell, causing the skin to wrinkle. This is particularly noticeable where the layer of dead cells is thickest, such as on the palms of the hands and soles of the feet."
Is this a similar mechanism or something different?
Palms of the hands and soles of the feat have a slightly different layers than the rest of the body If I recall well. That is they lack "stratum corneum" which is indeed pretty much made up from the dead skin cells. Which would imply, that if any parts of the skin do wrinkle because this layer of dead cells absorbs water, palms and feet soles would be exempted :S
So that's weird.
Ali Geda in some cases yes but in most science and religion are separated i pray to God everyday but i don't let it conflict with anything and I have a friend who's an astrophysicist and he believes the big bang theory but still reads his bible and believes in God although they conflict its better to ignore their conflicts and BELIEVE what you want to believe in but if you research it the definition of phd directly relates to religion many scientists in the past learned about religion and science ON TOP of that
Ali Geda I know many physicians that believe in evolution but religion and science are supposed to be separated its been that way for a long time even the greatest scientific minds in history have made references to this
Hiii friendsss ,, .. I’ve been using Maxelder argan cream every morning and night for about a month now and I'am so happy with the texture and appearance of my skin. The cream is hydrating but not too thick or oily.
I’ve noticed my eyes don’t look so tired in the morning and I have a natural glow. *Recommend w---nyarganoil—-c*
the skin on my hands become wrinkly within seconds when emerged in water, and it does not go back to normal as I have to wash my hands. I have been suffering for weeks now.
any suggestions would be appreciated.
Ok but why does it (at least to me) do that only in hot water. For example one day the sea was very hot and my fingers wrinkled and the next day the water was a colder and my fingers didn't wrinkle. (I was at about the same amount of time in the water). When taking baths it wrinkles. That's weird !
We've come so far as a species. But evolution hasn't allowed our physiology to keep up with our weirdly smart intellect. We can conceptualize better ways for our bodies to deal with things. It'll be really cool when we can actualize those ideals.
I think they're not wrinkly all the time, for the same reason, you shouldn't use off-road tires, on road. Off road tires are very course & bumpy, to channel away, and dig through loose material, like sand, dirt, mud, etcetera, but, pure off-road tires, are not meant for paved roads. They'll overheat, be worn out soon, and don't provide that much grip. On road tires, are more smooth, so they touch the roads more, wear more evenly, and can handle much higher speeds.
When it comes to vehicles, we should choose tires that match, how and where we ride or drive, how dedicated or diverse to different conditions, and requirements, but, it's great our feet & hands can adapt in minutes.
What if it's just because your fingers doesn't need blood to keep their insides moist as there's plenty of moisture in the surroundings, so your body just doesn't bother pumping as much blood to it's fingers as normal.
IMO at 1:00 when they mention the evolutionary function of the wrinkly hands(grippy hands), I believe evolutionary functions can only pertain to our survival, therefor the wrinkly or grippy hands is for preventing slipping and maybe better grips of weapons, because I believe sweat gives us wrinkly hands too?
I have noticed that you base the points on the paper by Kareklas K., which was published in 2013. According to the paper by Julia Haseleu, which was published in 2014, the experiment done by Kareklas K. was not reproducible, and hence, the points, though interesting, may not be true. Still, I believe more researches should and will be done on this topic, but so far, the points presented in the video seem not convincing enough.

constricted blood.. doesn't seem like an advantage at all.. slower blood circulation all of the time my of been good (as well as less sensitive fingers). but the better grip when required is an advantage.
I like your show but please don't use the word theory as a guess. This is a science show please refrain from muddying the water when it comes to that word. use one possible solution, or a hypothesis ,etc. Thanks. keep up the great work.
We covered this in uni, the other drawback from constantly wrinkled digits is that they are more prone to damage due to higher chance to catch on a sharp object and also more prone to breaks in the continuity of the skin due to weaker structure, opening up the deeper layers to infection.
The class of drugs that Levitra, Viagra, Stendra, and Cialis belong to are called PDE5 inhibitors. They work by relaxing tight blood vessels, allowing more blood to surge into the penis and cause an erection, says Gregory Bales, M.D., an associate professor of urology at the University of Chicago.
The little pills do the trick for more than two-thirds of men with Viagra protects the heart (ED). They also work for guys who simply need them for a short time to get their “confidence back,” says Michael Eisenberg, M.D., director of male reproductive medicine and surgery at Stanford University.
