It's probably an evolutionary adaptation to give us better grip in the water. People with nerve damage who can't feel their fingers also don't get pruny fingers, so there's clearly a "get pruny" signal coming from the brain or at least higher up in the nervous system.

- wpollock 1y agoI would assume that blood vessels contract to preserve heat, not to provide a better grip when swimming.
