You must have also noticed that while bathing or after staying in water for a long time, your fingers suddenly shrink and wrinkles form on them. At first glance it seems as if the skin has absorbed water, but the real story is much more interesting than this. This change is amazing not only in the skin but also in our brain and nerves. This is why scientists consider it a smart trick of the body.

Why do fingers change when they go into water?

When we stay in water for a long time, the skin of the fingers and toes gradually starts shrinking. Generally people assume that the skin has absorbed water, but scientific research shows that the reason for this is not water, but our nervous system. This entire process is under the control of the brain and is considered a neurological reaction.

How does the brain give the signal to shrink?

As soon as the fingers remain in water for a long time, the nerves present there become active. These nerves send signals to the brain, after which the blood vessels start shrinking. When the amount of blood in the fingers decreases, the skin above gets pulled inward. Due to this stretch, wrinkles start appearing on the skin.

Is this a disease?

No, not at all. Shrinkage of fingers in water is a completely normal process. Rather, doctors consider it a sign that your nerves are working properly. Interestingly, the fingers of people who have severe nerve damage do not shrink even in water. This means that the appearance of wrinkles is also a sign of the body being healthy.

What benefit do we get from shrinking?

This change is not just for the sake of seeing, but there is also a hidden benefit behind it. Shrunken fingers make it easier to hold wet things. Scientists believe that due to wrinkles, grooves are formed on the skin, due to which water comes out and the grip becomes stronger. Just like the grip built in car tires helps on wet roads.

The human body is expert in adapting itself according to the circumstances. Shrinking of fingers in water is an example of that. This process starts automatically and gradually ends as soon as it comes out of the water. It does not require any kind of medicine or treatment.

When might it be a matter of concern?

If the fingers do not shrink at all even after being in water for a long time, then a doctor can be consulted. This may be a sign of some nerve related problem. However, in most cases this is completely normal and there is no need to worry.
