Why do fingers wrinkle when they encounter water

There are two theories about this ......

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 (should be said to be a characteristic).

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.

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 **.

**Lack of protective layer of grease on the surface.

You should be a person who sweats easily with your palms, right? Because of the hot weather in summer, the hand will be in a wet state for a long time, compared with before, the oil protective film on the surface of the palm ** will disappear, and the water between the cells is very sufficient.

It is not because you drink too much water, but it may be caused by recent endocrine imbalance, not eating and resting regularly, etc., because even if you are not hot at this time, you may have continuous sweating in your palms. You should adjust the pace of life and pay attention to your diet. Also, although it is easy to get hot in summer, you should not eat too much cold food.

It is said that you can also supplement some vitamin C or something, but as for whether it has any effect, I don't know.

What causes fingers to become wrinkled after prolonged exposure to water?

What is the cause of this, do you know thank you.

1. Wrinkles when your hands are wet, there may be a lack of trace elements such as vitamin B and E, so you should arrange your diet scientifically and eat more vitamin-rich vegetables and fruits. You can do a trace element test for the body and take vitamin tablets directly. Drink plenty of water and drink plenty of milk every day.

2. If your hands wrinkle when they are wet, it may be that your body tells you that your endocrine disorder is in place. Endocrine disorders can lead to a decrease in immunity, which cannot be repaired well, and is fragile and prone to wrinkles. It is recommended to use the important to take care of it.

The body's endocrine system has returned to normal, and it will not be easy to wrinkle.

3. Some occupations will frequently come into contact with some toxic and harmful chemicals, such as laboratory experimenters, barbershop hairstylists, etc., will be exposed to a large number of chemicals containing mercury, benzene, lead and other chemicals, seriously injuring hands**. Even with gloves, these substances cannot be completely isolated. Therefore, the hands become extremely fragile and wrinkle when they get wet.

It is imperative to stay away from these harmful environments and avoid repeated friction injuries**.

This phenomenon is a normal phenomenon, because after soaking in water, the slack of the stratum corneum is caused. The epidermis becomes soft, which is why wrinkles are seen. So this also suggests that you can't soak in water for too long.

Normally, the ** on the hand is tight, and after being soaked in water for a long time, ** will absorb a lot of water and become loose, thus forming folds. You may ask why the ** in other parts of the body is not wrinkled, the reason is that there is more subcutaneous fat in other places on the body, even if the ** folds, the elasticity of the fat will stretch the folds apart, and the subcutaneous fat on the hands is relatively less, so the folds are preserved.

Why do fingers become wrinkled after being wet for a long time? After reading it, I finally know!
