That is why our fingers and toes frown from a long stay in the water

Have you ever wondered why from a long stay in the bath the skin on fingers and toes start to shrink?

Initially, scientists believed that this is due to the swelling of the upper layer of the skin. Due to the moisture absorption area of ​​the upper layer of the skin is greatly increased, but since it is connected with the lower layers of skin tissue, not having the ability to expand, the outer layer of skin wrinkling, which compensates for their increased area.

However, in 1935, some doctors have noticed that patients who suffered from nerve damage, skin on the fingers is not wrinkled. They concluded that the wrinkling of the skin of fingers - this is a reaction of the nervous system for a long stay in the water.

Neurologists believe that because our bodies take care of the best adhesion to the surface of objects and in damp conditions. In 2013, researchers tested the experiment, testing the ability of people with a non-shrunken and wrinkled fingers, which were to raise the various wet and dry items. It was found that patients with wrinkled fingers raised wet objects 12% faster.

Wrinkled skin on the fingers act as a protector on some car tires, increasing grip on objects and surfaces on which we walk.
