Question

why do fingers and toes wrinkle when left in water?

Answer 1

The waterproof coating on our skin gets rubbed away from areas of our bodies like our hands and feet that are frequently in contact with objects. If you immerse yourself in water with a lower concentration of dissolved salts than that of your cell contents, water will be absorbed by osmosis and cause your skin cells to swell. Since they are anchored to the tissues below, they are forced to corrugate to accommodate this.

Answer 2

$\textbf{Answer : }$


✔✔ For a long time, people thought the water caused skin to swell up and get puffy. Now researchers believe wrinkly fingers could be an autonomic nervous system reaction.

✔✔ Because it's easier to pick up wet objects with wrinkly fingers. Wrinkles on your fingers may give you more grip, kind of like treads on a car tire.

✔✔ It was once widely reported that water-immersion wrinkling was the result of osmosis.
