Why do our fingers and toes get extremely wrinkled after a long bath or swimming session?
I used to think my skin simply absorbed water like a sponge. What real neurological function triggers these distinct ridges on wet skin pads?

It is an active autonomic nervous system response. When skin nerves sense water immersion, they constrict blood vessels, wrinkling the skin to create tire-like treads that improve grip underwater.
