The palms of the hands will wrinkle very badly when soaked in water, what is the reason?

Due to the semi-permeable nature of the cell membrane, combined with prolonged immersion in water during bathing, a large amount of water flows between the epidermal and dermal layers. In addition, the epidermis layer is mainly composed of the stratum corneum, which swells after streaming, while the dermis layer below the stratum corneum is a connective tissue that does not swell due to a large amount of water absorption, which causes the volume difference between the inner and outer layers, resulting in the phenomenon of folding. The water between the stratum corneum and the dermis can also create a gap between the two layers, leading to the separation between the layers, which also promotes the occurrence of folds.

If it is accompanied by peeling, it is called dyshidrosis, and if you use public slippers and towels, you can spread it to other members of the family. Dyshidrosis is a type of hand eczema. People with this disease are generally prone to sweaty hands, and regular exposure to alkaline detergents and gasoline can also damage the natural protective layer of the hands, which can easily lead to this disease.

The disease is more common in spring and autumn, and is more common on the sides of the fingers, the abdomen of the fingers, and the palms, with small transparent blisters appearing, and then annular peeling. In some people, the blisters are not obvious, and they appear as peeling of the hands at the beginning, and the finger tips are more obvious. **Apply with triamcinone urea ointment.

For patients with sweaty hands, after not peeling the skin, you can use 2-3% formaldehyde to soak your hands, which can reduce hand sweating and prevent **.

If the wrinkles are very serious, or the blisters will wrinkle for a while, it means that the person is weak in blood and the blood is turbid. The reason for this is: eat less greens, eat less water, eat acidic foods, and do not eat the following foods

Oil pressed, pickled, cola, hamburger, milk, sugar, nuts, legumes, meat dishes, drink 3 liters of water a day. Eat more vegetables, you can eat rice, coarse grains, and you will get better. Don't say it's not nutritious, try it and you'll know the result.

**Too dry, the body is dehydrated, it is recommended to use some hand cream, drink more water, and eat more fruits.

To put it simply, because water has the effect of relaxing and softening tissues, the phenomenon that the fingers will wrinkle after soaking in water is caused by the swelling of the stratum corneum cells in the fingers and other parts.

Causes of wrinkles on the surface of the fingers of the hands and feet include:

1.The stratum corneum in these areas** is thicker and has a significant swelling effect. Of course, it is difficult to wrinkle parts that are too thick and hard, such as the base of the palm.

2.There are no sebaceous glands in these areas. The sebaceous glands secrete sebum, which is an oil that covers the surface of the ** and has a blocking effect on moisture. Areas with less sebum make it easier for moisture to enter the stratum corneum.

3.To put it simply, because water has the effect of relaxing and softening tissues, the phenomenon that the fingers will wrinkle after soaking in water is caused by the water absorption and expansion of the stratum corneum cells in the fingers and other parts. Our ** is actually covered with a thin layer of grease, in order to prevent ** from absorbing water directly from the outside.

There is not much subcutaneous fat in these areas. Fat has good elasticity, and areas with a lot of subcutaneous fat are less prone to wrinkles.

4.Some scientists have found that the production of wrinkles is related to nerves. In areas where the nerve is out of control, soaking does not produce wrinkles.

Later, it was further found that when ** was soaked in water, the intracellular electrolyte balance changed, causing neural activity in these parts to begin to increase. There are synaptic connections between nerves and blood vessels, and increased nerve activity will cause blood vessels to constrict, reducing blood flow to these areas. And this in turn makes the ** tension of these parts decrease, temporarily become loose and folded.

Because the fingers and toes are controlled by the autonomic nervous system (also known as the autonomic nervous system), when the autonomic nervous system is soaked in water for a period of time, the autonomic nervous system will send instructions to make the subcutaneous tissue of the finger tips and toe tips constrict, and the volume will be reduced, while the surface area of the fingers and toes will remain unchanged, so the folds will appear.

Wrinkles on the fingers can help humans better grasp objects in the water (such as fish) because the wrinkled fingers are actually used to expel water to enhance the friction of the fingers; And the wrinkles on the toes can help humans walk better in the water, because the wrinkles are equivalent to the lines of the tire, which can make it easier for the water to flow down the ravine, so that a negative pressure band is formed, which increases adhesion.

The reason why the hands are wrinkled when soaked in fresh water for a period of time is that the concentration of cell fluid in the body is higher than that of fresh water, and the water will flow into the epidermal cells, so the cells will swell and deform, and the hands will look wrinkled. In addition, there is a bundle of elastic proteins at the bottom that is tightly bonded to the epidermal cells, resulting in the contraction or uneven swelling of the hand.

There are two types of subdivision of hand wrinkles when exposed to water.

Clause. First, it is fast, the hand is in the water for a few minutes, the fingertips are wrinkled, which is caused by the contraction of small blood vessels and small nerves in the dermis of the fingers, which may be an adaptive nerve reflex of the human body, which is produced for people to hold objects in the water and increase friction.

Clause. Second, it takes a little longer for the hands to wrinkle when exposed to water, which may take half an hour or longer, which is caused by the water absorption and expansion of the stratum corneum of the hands. Because of the structural characteristics of the hand, the first is the thickness of the stratum corneum, and the second is the lack of fat layer under the epidermis, so the stratum corneum absorbs water and expands, and there is no fat layer under the skin to stretch it out, so that the stratum corneum is stacked and squeezed together due to the increase in the surface area of water absorption, and the stratum corneum looks wrinkled.

This is a normal physiological phenomenon in the human body, and there is no need to worry too much. However, if it is difficult to recover after an attack, it may be due to a lack of collagen and a decrease in metabolic capacity.

It is necessary to eat more foods such as beef and pig trotters, and at the same time, you can also eat more vegetables and fruits to supplement vitamins and improve the metabolic ability. Don't soak your hands in water for a long time, take good care of your hands, and apply some moisturizer to your hands to make your hands smoother and more elastic.

The reasons why your hands wrinkle when you soak in water are as follows:

**It is actually covered with a thin layer of grease, in order to prevent ** from absorbing water directly from the outside. However, when soaked in warm or hot water for about half an hour, this layer of grease will be removed by warm water, so it will begin to absorb water. **The surface is an epidermal layer, and below the epidermis is the dermis layer; The epidermis is not completely tightly bonded to the dermis, and the epidermis is only tightly bound to the dermis by connective tissue in some areas, but not in others; Therefore, when the epidermis absorbs edema, the binding place is confined and concave; From the outside, the surface of the ** is concave and protruding, like wrinkles.

Since the palms and toes of the hands and feet are the thickest part of the epidermis of the whole body, the phenomenon of wrinkles is obvious. **Other parts of the body should also have this effect, but it is less likely to be detected. If you soak in water for too long, the epidermis absorbs water and swells, so it becomes wrinkled. In the past, some women specialized in washing clothes for others, their hands were soaked in water for a long time, and their fingers were often wrinkled, which became an occupational disease.

This is a normal phenomenon, when soaking in water, your ** cells will absorb water and expand, so the volume will become larger, and there will be wrinkles, don't worry very much, just like noodles or noodles After you soak it, he will also become larger, and wrinkles will appear.

In fact, wrinkling originates from the outermost epidermal epithelium. Usually, if you soak in the water for half an hour, you will get wrinkles. The epithelium contains a protein called keratin, which makes your ** stronger and more moisturized.

Dead keratin cells make up the epidermis itself, the so-called stratum corneum.

Dead keratinocytes in the stratum corneum absorb water very easily and swell if soaked in water for too long. But the living, deep stratum corneum doesn't absorb water. As the dead cell layer swells, it takes up more surface space.

These dead stratum corneum cells will be connected to the living stratum corneum cells underneath, and the dead stratum corneum cells will have nowhere to go. In this way, the cuticle wrinkles are actually done to create a new, temporary surface layer to house the cells. The researchers looked at other theories that can cause wrinkling, such as whether the constriction of blood vessels also causes wrinkling.

If most of the body is soaked in water, why do only the hands and feet wrinkle? Because the hands and feet are used very frequently, the feet and hands are relatively thick, so the cuticles of the hands and feet are relatively thick compared to the rest of the body, which makes them prone to wrinkles when soaked in water.

People grow around because of aging due to sun damage, dryness or loss of fat tissue. Wrinkles due to water absorption are temporary, and they disappear when the water dries.

Don't be nervous, don't continue to soak in water, and you'll be fine in two days.

It should be noted that the epidermis of the hand is relatively fragile and easy to break at this time, so do not do rough work for the time being, and prevent it from being cut by sharp objects and sharp paper.

People who have studied biological cytology know that when there is a concentration difference between the inside and outside of the cell, some ions will move from the low concentration to the high concentration, and when your hands are soaked in water for a long time, the water molecules will enter your ** cells, because only the outer ** cells absorb water, and at the same time are pulled by the inner cells, and the external manifestations are finger wrinkles.

Causes of wrinkling:

1. The thickest and outermost layer of the palm and sole of the human hand is called the stratum corneum, which is composed of tough dead cells.

Under normal conditions, the cells of the stratum corneum are quite dry because animal cells do not have a cell wall. If soaked for a long time, they will swell due to the absorption of water.

The cells below the stratum corneum, on the other hand, do not absorb water and therefore do not swell with the cells on the surface.

**The cells in the surface layer will swell due to the excessive water absorption, and the cells will be squeezed from cell to cell, and the volume will increase, so they will fold to increase the surface area. The epidermis is raised upward, which is the wrinkling we see After a long time of blistering, it will wrinkle, which is also a constriction of blood vessels.

2. If the wrinkle is very severe, or the blister will wrinkle after a while, the reason is: lack of vitamins, vegetables, and water to eat less, to eat more fruits and vegetables.

Because the concentration of fluid in the body is higher than that of fresh water, when the hands are soaked in fresh water for a period of time, the water will flow into the epidermal cells, and the cells will swell and deform.

On the contrary, since the concentration of fluid in the body is lower than that of seawater, when we swim in the sea, water flows out of the epidermal cells, and the cells shrink and deform.

At the same time, there is a bundle of elastic proteins at the bottom of the epidermal cells that are closely linked, and after the cells change, the protein shrinks or swells unevenly, and wrinkles will also occur.

Because the hand is soaked in laundry detergent water or soapy water, the concentration of cell fluid in the cells on the hand is lower than the concentration of the laundry detergent or soap liquid, and the cells lose water and shrink, so the hand will wrinkle.
