How come when you have a bath only your hands and feet go wrinkley?

Question

Just wondered (:

Answer 1

I figure it's because there is so much skin on those parts that come to an end. The soles of your feet are actually the location in which there is the thickest skin. Your eyelids are the thinnest, FYI.

Hope I helped.

Answer 2

Here is your answer.

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

stay in for awhile longer

Answer 4

Perhaps it has to do with their ability to absorb water.
