Wrinkled Fingers and Toes - Why?

We swim, we bathe, and there they are – those wrinkled, pruney fingers and toes. Why do they do this? They seem to get more wrinkled the longer they are wet! According to Mark A. Changizi, a neuroscientist, he suggests this is a great example of our human design.

In Changizi’s studies, he asks why when plunged into water, the skin doesn’t absorb the water and become filled and plump but instead gets pruney and wrinkled? He found the nervous system is involved. Oddly, fingers and toes do not prune up in people with severed nerves. In his research it is clear to him that this was not just a physical reaction, it was designed.

Furthermore, it's been discovered submersion isn't necessarily the only way to make these orbs of wrinkles.  Walking in wet grass will also produce this effect on your feet. It is the body’s way of providing channels that help water drain away and provide some resistance against slipperiness.

He explains it with this analogy: When dry, our fingers and toes are smooth like racing tires. When they get wet, they transform into all weather tires that can provide traction.

Wow! We ARE fearfully and wonderfully made!
