Why Do Our Fingers Prune When They Get Wet?

Have you ever noticed that when you spend too long taking a bath, doing dishes, or any other activity that involves constant contact with water, your fingers get wrinkled?

Of course you have! Anyone that has ever gone swimming in a pool has experienced this phenomenon, but why does it occur?

Nothing to Do With Osmosis

In the past, it was believed that the skin became wrinkled due to a phenomenon called osmosis, which is the process of water passing into the outer layer of the skin, causing swell up. Even today, many people believe that this is the reason for the “prune-like” appearance of fingers after long-time exposure to water. However, in 1935, this theory was shown to be incorrect.

So what’s the real reason for this bizarre phenomenon of our fingers? Watch this video to find out!
