After bathing or soaking your hands or feet in water for a certain period of time, the skin on the tips of your fingers and toes will become wrinkled.

The phenomenon of wrinkles that everyone encounters in life

In life, everyone knows that the skin on the tips of the toes and hands will dry if the hands and feet are soaked in water for more than 5 minutes, but this process will be shortened if the water is warm or hot.

Currently, scientists cannot explain for sure why the human body produces this phenomenon.

Many theories believe that wrinkled skin on hands and feet is due to osmosis, causing the skin to absorb water and swell.

In fact, in many cases, if certain nerve cells are intentionally or unintentionally removed, the skin on the fingertips and toes will no longer wrinkle when soaked in water.

In addition, wrinkled skin is also related to blood vessel constriction.

Thus, we know some key points of this strange change in the body, but we still do not clearly understand the mechanism and cause of this phenomenon.

What is the use of wrinkled hand skin?

Every changing part of the body is for the purpose of adapting, making human life easier.

Similar to the reason why car drivers have to periodically change rubber tires when old tires are worn out, the grooves and detailed patterns on tires help reduce slipping and provide better grip in wet or sunny conditions.

Some scientists believe that wrinkling skin helps people grip objects in water or wet environments more firmly.

From there, it can be seen that the human body is indeed very miraculous, it transforms itself to adapt to the environment before people even realize and explain the purpose of that transformation.
