why do are palms wrinkle when in water for a long time?

I do not know just how scientific you want this to be, so I will give you the reason to a collegiate level. The plasma membrane in your dermal cells (as in most somatic cells) is made up of a lipid bilayer. Water can travel through a protein channel called the aquaporin or it can go directly through the lipid bilayer in certain occasions (though large amounts cannot as the middle of the bilayer is made up of hydrophobic tails). When water is exposed to the skin, diffusion occurs since there is a greater concentration of water outside the dermal cells than inside, and this is called osmosis. Therefore, these cells take in large amounts of water (up until a point where the aquaporin is closed to prevent cytolysis, or the death of cells due to overexpansion). The interstitial tissue also absorbs water, and thus, the dermal area expands. Since the dermal area is larger than it really should be, it "folds" to a point, causing wrinkles. Hope that helped.

MY HANDS ARE LIKE THAT TOO. WHEN I USE THE COMPUTER THEY REALLY GET COLD OR WHEN I READ A BOOK. AS LONG AS I KEEP MOVING THEM THEY'RE OK. JUST PART OF GROWING UP.

They shrivel because of the process of osmosis. This is how all water is moved in the body. It is simple diffusion through a semipermeable membrane. When your hand is in the water, there is a higher concentration of water inside you finger tissues than outside your fingers in the pool water. This is the case because pool water contains impurities. Osmosis will work to equalize the concentration of water and thus you fingers will lose water to the pool water. I know this is complicated but it is how we work.

Some people think it's because the skin expands to allow extra water inside. The expanded skin ends up looking really wrinkly. Other people think that it's because the skin is tied down to the tissue underneath in certain places. So when the skin is full of water, it swells up (gets puffy), but only in places where it is not tied down, which makes it look wrinkly.

i'm guessing, its dried soap.. or your skin is really dry..

You have contact dermatitis. You are getting an allergic reaction to something in the water. In fact this is an improper immune response.

Some people get wrinkles from being in the sun too much

Skin is in several layers. The top layers absorb water faster, so they expand and cause the "wrinkled' effect.

Because the skin cells absorb the water. Its not harmful and will return to normal very quickly after you dry yourself off.

I'm not sure but, it is where you have thicker skin due to calluses and that part of the skin absorbs more moisture and become gorged with water and stretches. Then your body starts to remove the extra moisture leaving the stretched skin to look wrinkled.

The answer is a combination of several factors.\n\nThe skin is designed so as to limit "wrinkling" while swimming. (hydrodynamics) If u look at the skin closely, they consist of placoid scales which r smooth in one direction (swimming direction), and rough in the other direction.\n\nSharks r seriously buffed up, which aids in generating work.\n\nFins stabilise the body to prevent it from swimming upside down or in a circle\n\nThey belong to the chondrichthyes... cartilaginous fishes. This skeletal system is lighter than boney frames and allows for greater flexibility. Both characteristics COULD help in swimming. (There r, however, many fast marine animals with boney frames such as the dolphin or swordfish).\n\nThe tail is the main propulsion force. Which works in coordination with it's respiratory and circulatory system. As water passes over the gills, the lamellae r oxygenated, and at the same time release waste products (co2). So, if the shark swims slowly, the respiration rate decreases... and if he doesn't swim at all, he suffocates. I guess sharks swim fast because they have to. Haha. I hope that's helpful.

they probably have more salt/sodium in their skin then u do.it has to do with that.

my hands are the same way and have been for 20 years. i do not drink any alcoholic beverages. i dont see how it could be from drinking.

try changing your soap or towel.  I doubt it is the water because then your hand would itch after washing your hand or doing anything in tap water.  IF the itching stops or continues with one gone or the other gone, you know you have you culprit

Your hands and the bottoms of your feet are more "water permeable" than the rest of your body because they have more sweat glands in them but no oil glands.  So when you expose them to water, and even more so with hot water, for extended periods, the water will begin to go back in just as it is able to come out. When the skin soaks up enough water, which sometimes isn't very much, it begins to expand and prune.\nWeather along with humidity and also one's age has a lot to do with how quickly the skin becomes waterlogged.

Your skin has a limited capacity for keeping water out. \nAfter a long bath, your skin will absorb some water, and will tend to expand its surface. However, due to the lack of space for expansion, it gets wrinckled.

no sunlight and the fluid that you would normally have sweated off is trapped therefore making your skin soggy - also this extra fluid will make you look paler too.
