Why do your hands wrinkle after soaking in water for a long time?

Because water has the effect of relaxing and softening tissues.

Our ** is actually covered with a thin layer of grease, in order to prevent ** from absorbing water directly from the outside. However, when we soak 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. Our **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 soaked in water for a long time, and their fingers were often wrinkled, which became an occupational disease.

Another way to put it:

Since the concentration of fluid in the body is higher than that of fresh water, when the fingers are immersed in fresh water for a period of time, 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 will flow out of the epidermal cells, and the cells will shrink and deform.

In addition, there are bundles of elastic proteins at the bottom of the skin that are tightly adhered to the epidermal cells, resulting in uneven contraction or swelling of the fingers, resulting in wrinkled skin.

Hello. To put it simply, the reason is that the area becomes larger due to the absorption of water, so wrinkles are produced.

Just like the brain, babies are almost wrinkle-free, and when they grow, folds occur when the brain area grows larger.

Because apprentice, your hands are more delicate

The correct answer is ** vasoconstriction caused by low-level nerve reflexes, which is the result of natural selection during the ape-like period. The apes, which are able to form wrinkles in the hands and feet, have not been starved to death and drowned in their long evolution. As a result, these valuable genes have been preserved to the present day.

If your hands are wrinkled after soaking in the water for a long time, you don't need to worry, your hands will return to normal after a while after they leave the water.

When the hand is left in water for a period of time, the blood vessels in the subcutaneous tissue at the fingertip area will shrink, resulting in a decrease in volume, because the surface area of ** remains the same, so there will be folds.

Another study found that finger wrinkling is the result of blood vessel contraction, which is a response of the autonomic nervous system, which is an active process, rather than a passive response after water absorption, as previously believed.

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 **.

Why do your hands wrinkle after soaking in water for a long time, it's really a matter of knowledge.

Why do my fingers wrinkle after soaking in water for a long time?

Wear that thin rubber sleeve and rub some petroleum jelly on your hands before you start.

The cell membrane of the epidermis is semi-permeable and prolonged immersion in water allows a large amount of water to enter between the epidermis and the dermis.

The epidermis layer is mainly composed of the stratum corneum, which swells (elongates) when exposed to water, while the dermis layer below the stratum corneum is connective tissue and does not swell, so that the volume difference between the inner and outer layers is the phenomenon of elongation (swelling) of the epidermal layer. The presence of water between the stratum corneum and the dermis creates a gap between the two layers, and separates the layers from each other, so that the folds are created.

Reason: The traditional view is that finger wrinkling is due to the swelling of ** due to prolonged soaking. Recent studies have shown that wrinkling is caused by soaking in water to constrict blood vessels, resulting in changes in fingertips, which is controlled by the body's sympathetic nervous system.

Many people have had the experience of washing dishes with their bare hands, and their fingers and fingertips begin to wrinkle after a while. British researchers have experimentally proven that finger wrinkling has a practical effect, which can enhance the grip on wet objects and prevent dishes from slipping.

Researchers believe this may have been the result of evolution, helping human ancestors walk and forage in humid environments. Wrinkles help to strengthen people's grip on wet objects, making it easier for people to pick up objects underwater or carry objects with wet surfaces.

Why do you soak in water for a long time, your fingers will wrinkle, and after reading the rising posture?

The cell membrane of the epidermis is semi-permeable and prolonged immersion in water allows a large amount of water to enter between the epidermis and the dermis.

The epidermis layer is mainly composed of the stratum corneum, which swells (elongates) when exposed to water, while the dermis layer below the stratum corneum is connective tissue and does not swell, so that the volume difference between the inner and outer layers is the phenomenon of elongation (swelling) of the epidermal layer. The presence of water between the stratum corneum and the dermis creates a gap between the two layers, and separates the layers from each other, so that the folds are created.

There is a dense keratinic stratum layer (keratin) on the surface of the human body, which can avoid the subcutaneous and muscle tissue from pollution and the invasion of some bacteria; Because this stratum corneum is "absorbent", just like paper, the fibrous tissue will swell after absorbing a large amount of water, and because the surface area of the human body is unchanged, when the swelling phenomenon occurs and the surface area "increases", it will produce wrinkling. If the stratum corneum of the epidermis is relatively more oily, it may absorb less water, so the wrinkles may be slightly less "obvious", and vice versa; Dry, that is, non-oily people, if they are very dry, they are prone to cracks, which is caused by excessive shrinkage, because this kind of **loss of water is more, and oily ** people rarely crack This is the truth, and it does not indicate a person's physical problems.

One possible reason may not be that way.

Other parts of the body should have the same effect, but it is less noticeable. ”

The reason why fingers are more prone to wrinkles may also be due to non-slip, just like the pattern on the surface of a car tire, which can enhance the ability to grasp objects in wet or water.

And only the fingers and toes will be obvious.
