when we keep our hands in water for more time they become more wet & some times finger tips gets wrikled why ?

Answer 1

Because water has soaked into the callus on your skin, and made it swell and wrinkle up. The callus is usually thickest on your hands and feet.

There are a few layers in the skin - the dermis underneath, and the epidermis on the outside. The epidermis of your skin is quite thin, from a 10th of a millimetre over the eyelids to more than l mm thick on the soles of your feet. The epidermis is full of skin cells, and it's supported and nourished by the dermis underneath.

Now there's a non-waterproof layer of your skin - the thick layer of callus that you generate on your feet (if you walk a lot), and on your hands (if you do physical work with your hands).



When you're in a bath for half an hour or so, water can soak into the callus.
Unless you're one of those religious people who crawls on your belly for hundreds of kilometres, you don't have much callus on your belly, which is why you don't get a wrinkled belly when you soak in a bath.

So the reason that you wrinkle when you sit in water for a long time, is because the water soaks into any skin on your body that has lots of callus on it.

Answer 3

The skin cells of your hands go through plasmolysis. Plasmolysis refers to the shrinking of cells. This happens when cells are existing in a hypertonic environment. If a cell has more solutes outside of it than its inside, then the solution outside is said to be hypotonic. In such case, the water goes out the skin cells through osmosis. Here, the hypertonic environment is the water. It has more solutes than your skin cells because water contains many minerals. So the water in your skin cells diffuses out to achieve equilibrium. Hence, your fingers get wrinkled when the water leaves your skin cells.
I hope this helps.

Answer 4

the water soaks into the non-waterproof skin on the hands and feet called the callus. skin is water proof, but the most used parts arent because of the build up of callus, like on your feet and hands. the more hard work your hands do, the more they would wrinkle. imagine the whole body getting wrinkled. yuk

Answer 5

when dry your skin is covered in water tight oils. after a while of being in water, these oils wash away and water takes their place. after even more time, the water will seep into the skin taking place of all of the oil and making it puffy and wrinkled. usually, as soon as the skin looses contact with the water, your oil production starts again.
