Why does the hands and legs gets wrinkled after bathing?

Some parts of our body gets contracted after we bath. Especially the parts of legs, fingers mostly gets contracted and they gets wrinkled.

Why do this happens?
Some people tells that it is due to the reaction of bio chemical. When we stay in water our ligaments of the skin gets out which causes the contraction.

But scientist says that this is not only osmosis. They says that wherever it gets wrinkled if we cut some nerves of that place there will be no wrinkle.

The wrinkled skin shows that our immunity power is working well.

American Scientist Mark Changiji says that our body the changing environment of the body changes us. Wrinkle on water is the same so we need to take it as normal way.

At 2011 this was found at one monkey as well. The only meaning is that our reach should be strong on water.

One of the use in Britain at 2013 showed that wet hand can do the things in water here and there faster.

But in Germany same thing went opposite. It is found that wet or dry hand there is no difference in their work.

Similarly in Taiwan it is found that wet hand suffers more hard to lift out the things.

Wet legs has the risk to get slip. The wrinkles leg proves that there is less oily and wet wrinkle is easy to carry on.
