Why do your fingers look like prunes after swimming for a long time?

pruney fingers are caused by shrinking blood vessels. When you soak in water, your nervous system sends a message to your blood vessels to shrink. Your body responds by sending blood away from the area, and the loss of blood volume makes your vessels thinner.

This is because when you swim in a pool for a while your hand seem to be pruney and it is because when the hand is soaked in water, the nervous system sends a message to the blood vessels in your hand to shrink.

And the reduction of blood from the area in your which is soaked and then your hand seems like pruney
