The wrinkly phenomenon that everyone meets in life

In life, everyone knows that the skin of the toes and hands will soak them in water for more than 5 minutes, but this process will be shortened if the water is warm or hot. If the water temperature is above 40 degrees Celsius, it only takes 3-5 minutes to soak for severe wrinkling. A special feature of this phenomenon is that it does not appear in areas other than the hands and feet.

Currently, scientists have not been able to clearly explain why the human body produces this phenomenon.

Many hypotheses that wrinkled limbs are caused by osmosis, causing the skin to absorb water and inflate. However, this explanation is not necessarily convincing, because we all know that water does not naturally soak into the fingers. The body needs to work in a way that allows water from outside to penetrate the inner skin layers.

Some scientists believe that wrinkled skin will help people hold objects in water or a moist environment more firmly. As for the soles of the feet, the wrinkled skin will help increase grip when walking, limiting slip. This hypothesis is quite reasonable considering the harsh habitats of human ancestors.
