😳 WHY? ❓❓
Why do our fingers get wrinkled after a long bath?
Many people think the skin simply soaks up water and swells, but the real reason lies in our nerves. When the fingers and toes stay in water for several minutes, the nervous system signals the tiny blood vessels under the skin to narrow. The soft tissue beneath shrinks a little, and the outer skin, which stays the same size, folds into wrinkles. Doctors know this because fingers with damaged nerves do not wrinkle. Scientists think the wrinkles may work like the treads on a tyre, helping us grip wet objects better. Once the skin dries, the blood flow returns and the wrinkles disappear.
