Why do you get vitiligo from sun exposure? Want to know why

It is because after sun exposure, melanocytes are hyperfunctional, and their tyrosinase and dopa oxidation intermediate substances are destroyed, which is an important protective mechanism, once this protective mechanism, consumption declines, melanin may be destroyed; Second, it may be due to the excessive production or accumulation of melanin, an intermediate substance that can be synthesized by the cells themselves, and damage the melanocytes, resulting in vitiligo. Proper sunbathing is beneficial, but don't get sun when the sun is strong, and take sun protection measures when you go out in the summer. This degree is also very easy to master, proper sun exposure is very comfortable, and when you feel that the sun is uncomfortable on your face, you should not get sunburned.

Introduction of experts from Nanjing Vitiligo Research Institute: Hello: The occurrence of vitiligo due to frequent sun exposure is due to the influence of genetic, immune, mental and other factors, which causes local ** and melanin synthesis disorders in hair follicles.

The ultraviolet rays in the sun can promote melanin metabolism, so proper exposure to the sun can make melanocytes transfer to the cortex, so that the skin tone is deepened, which is conducive to vitiligo**. However, in the hot summer, the ultraviolet rays in the sunlight can inhibit the metabolism of melanin, which is not conducive to the synthesis of melanin, so the sun should be avoided in summer. Vitiligo is found early**, and early vitiligo can be **.

Patients with vitiligo should avoid exposure to the sun, strong light exposure, but can receive an appropriate amount of long-wave ultraviolet radiation that can promote melanin metabolism and not cause inflammation. When the autumn, winter and spring sunlight obliquely shines on the ground, choose around noon, and the sunshine time can be longer; In summer, the sun shines directly on the ground, and the irradiation is appropriate in the morning and evening, and if you choose to irradiate through the glass at noon, the irradiation time can be shorter and the number of times can be more. Patients should be assisted in sun exposure under the guidance of a doctor during the process.

Kunming Fumei: Vitiligo patients need to pay attention to their diet: Vitiligo patients often eat food:

1. Usually eat more foods containing tyrosine and minerals, meat (beef, rabbit, lean pork), animal liver, eggs (eggs, duck eggs, quail eggs), beans (soybeans, peas, mung beans, soy products), vegetables (fresh vegetables, radish, eggplant, winter bamboo shoots, fungus, kelp, etc.), peanuts, black sesame, walnuts, raisins, snails, clams and other shellfish. 2. A fresh pork liver, cooked without any condiments. It can also be dipped in tribulus terrestris noodles at the same time.

3. A fresh pork belly, cooked in water. Don't have sex. 4. Rub a piece of ginger on the outside of the slice and rub it with a little force to make the ** redness and slight pain.

Dietary contraindications for vitiligo patients: avoid eating onions, garlic, fish, shrimp, mutton, chili peppers, and alcohol.

This is possible, don't ignore this matter, friends, search Huahai on it, and take a look.

Exposure to the sun generally cannot cause vitiligo, it can**. After exposure to the sun, it may cause **mucosal damage, and there will be **color blackening or **peeling**, and there will be **uneven color, which will not cause vitiligo, which can be done by applying drugs**.

After the sun exposure, it is also necessary to do a good job of ** care, it is best to rinse with cold water or apply it with ice packs, which can quickly reduce the ** temperature.

Exposure to the sun generally cannot cause vitiligo, but it can.

Yes, go to a regular hospital to prescribe medicine.

For vitiligo patients, proper sunlight exposure in life is conducive to the production of melanin in ** and helps the recovery of vitiligo. However, people with vitiligo should avoid prolonged exposure to strong sunlight, which can cause vitiligo to intensify and worsen. After checking the computer, excerpted from Huahai.com, vitiligo patients should avoid direct contact with sunlight for a long time, take sunscreen measures, and avoid the damage of strong ultraviolet rays.

Causes of vitiligo.

1.Trauma. Trauma can damage melanocytes and**, if not treated in time, it may cause a homomorphic reaction, causing vitiligo to appear, so to avoid the occurrence of vitiligo, it should be treated promptly after the occurrence of trauma.

2.Immunity.

If the body's immunity is too low, it may cause the occurrence of diseases, including vitiligo. In order to prevent the occurrence of vitiligo, patients should pay attention to actively participate in physical exercise to improve their immunity.

3.Diet. If the patient has an irregular diet for a long time, then it may affect the synthesis of melanin due to lack of nutrients, causing the occurrence of vitiligo.

There are many causes of vitiligo, and it is recommended to prevent it from various aspects. If vitiligo has already occurred, then it is recommended that the patient should go to a professional vitiligo hospital in time for effective treatment**.

1. Sun exposure will bring color changes to the **, especially in the hot summer, some people can't avoid working in the open air, so these people must take sunscreen measures to avoid vitiligo.

2. Ultraviolet rays can synthesize the activity of tyrosinase, an enzyme necessary for melanin, thereby promoting the metabolism of melanin, so long-term sun exposure is of certain benefit to vitiligo patients, but if it is exposed to the sun in the hot summer, it will burn ** and cause secondary damage to the original damaged **, therefore, patients must remember that if they go out in summer, they must do a good job of sun protection.

3. Vitiligo patients have a lower defense ability against ultraviolet rays than normal people, and if they are exposed to the sun for a long time, it may induce the occurrence of ** cancer.

There is definitely an impact. Some patients with vitiligo can bask in the sun, but some can't bask in the sun, and if some patients are taking drugs**, especially using bright drugs**, in this case, they can't bask in the sun too much, so they need to be based on their specific situation. If the condition of vitiligo patients is relatively stable and well controlled, it is possible to get proper sun exposure in this case, but it is necessary to pay attention to avoid it if the sun is strong in summer.

Long-term exposure to the sun has an impact on vitiligo, pay attention to sun protection, wear a sunhat, wear sun-protective clothing, apply sunscreen on the face, and try to avoid the strongest time period of the sun at noon.

Work is long-term work outside the home is long-term exposure to the sun, I don't know if it has an impact on vitiligo?That must be a job that has been exposed to the sun for a long time, and I don't know if it has an impact on vitiligo?That must have had an impact.

Long-term outdoor exposure is very unfavorable to white**, patients with vitiligo should do a good job of sun protection outdoors, wear sunhat and sun-protective clothing, and avoid exposure to the sun during the most intense time period at noon in summer.

If it has an impact, you must pay attention not to expose it to the sun, and it is recommended to change the working environment.

Be sure not to be exposed to the sun, if you are exposed to the sun regularly, it will definitely have an impact on vitiligo.

Long-term exposure to the sun will burn**, so that the damage will cause secondary injury, which is not conducive to the recovery of the condition.

Hello, vitiligo patients should avoid sun exposure. You can wear sun-protective clothing and a sun-protective hat when you go out.

Long-term exposure to the sun is not good for your health, first of all, you must learn to protect yourself, and you must insist on it.

Sun exposure is one of the causes of vitiligo, and it is important to protect yourself.

Take your own precautions and try not to expose yourself to the sun.

Statistics show that about 7% of patients with vitiligo develop after exposure to the sun, what is the reason?

We believe that the first is that melanocytes are hyperfunctional after sun exposure, and the intermediate substances oxidized by tyrosinase and dopa are destroyed, so that melanin is destroyed; The second is that the cells themselves can synthesize intermediate substances and overproduce or accumulate, which damages melanocytes and causes white patches.

**。Melanin is produced by melanocytes and is an important determinant of color. If melanocytes are destroyed, it leads to a decrease in melanin production, which eventually leads to vitiligo.

The specifics of vitiligo are unclear and may be related to autoimmune diseases, genetics, neurochemicals, etc. Basic**Autoimmune Disease: Non-segmental vitiligo is considered an autoimmune disease. In autoimmune diseases, the immune system is disordered, and actions that attack healthy cells and tissues in the body occur instead of being responsible for attacking foreign pathogens like the normal immune system.

Patients with non-segmental vitiligo produce antibodies to their own melanocytes mainly due to a disorder of the immune system, which in turn leads to a decrease in melanin production.

Vitiligo can also be complicated by other autoimmune diseases, such as thyroid disease (such as hyperthyroidism), autoimmune polyglandular syndrome, etc., but not all patients with vitiligo will develop these diseases. Genetic factorsSome patients have familial aggregation, which belongs to the category of polygenic diseases. Neurochemicals Segmental vitiligo is thought to be caused by biochemicals released from nerve endings.

These substances have a destructive effect on melanocytes, resulting in a decrease in melanin production. Predisposing factorsVitiligo can be triggered by a variety of factors: mental factors, such as overwork, anxiety, and stress.

Injuries, such as severe sunburns or cuts. Exposure to certain chemicals in life or work. Childbirth, trauma.

The cause of vitiligo is unknown, but when the autoimmune function is abnormal, the melanocytes are destroyed, resulting in the loss and disappearance of pigment, which causes vitiligo. Vitiligo can also be induced by trauma, sun exposure, and some photosensitive drugs. Deficiency of trace elements and low autoimmunity can induce vitiligo.

The onset of vitiligo is related to genetic, neuropsychiatric, autoimmune function and endocrine metabolism disorders. Its pathogenesis is related to genetic, neuropsychiatric, autoimmune function and endocrine and metabolic disorders. Sun exposure and trauma can induce or aggravate the condition.

Trauma can induce or exacerbate the condition. It is recommended that you avoid sun exposure, patients are especially sensitive, so you should initially take appropriate sunscreen measures, do not let the skin directly exposed to the scorching sun, and use sunscreen products suitable for skin type and venue, hats, parasols, long-sleeved coats, etc., which can also effectively block the damage of ultraviolet rays.

Because of the irregular work and rest time, it has caused a decline in physical fitness, malnutrition caused by dieting, endocrine disorders in Nanchang Vitiligo Hospital and so on.
