In this way, why do my hands get wrinkly so fast in water?

Pruney fingers occur when the nervous system sends a message to the blood vessels to become narrower. Immersion in water is the most common cause of pruney fingers. There are other, less common causes of wrinkling or puckering of the skin on the fingers, however.

Also, why do fingers and toes wrinkle when left in water? The real reason is that blood vessels just under the skin constrict as an involuntary nervous system reaction to skin's immersion in water. This causes the upper layers of skin to pucker and wrinkle. “Maybe we wrinkle, so like tire treads, our fingers and toes can get better traction in wet conditions.”
