It itches to sleep at night in summer, just turn on the air conditioner. I have urticaria. I don't know if this is the reason. What should we do?

Urticaria is caused by some external or internal factors of the body, which leads to temporary inflammation of the skin mucosa accompanied by congestion, leading to local edema of the skin, and red patches may appear on the face, hands and stomach. The greater the grip, the easier it is to itch. And the number of attacks is irregular, maybe once a day or many times a day.

Urticaria is characterized by rapid onset, sudden skin damage, and local red powder clusters of different sizes. Severe itching and burning sensation will spread all over the body.

Urticaria is actually quite common. 20% people in life may have had urticaria, especially women, and the probability of urticaria is 2-3 times that of men.

The high incidence of urticaria in summer is mainly related to the following three aspects.

First, damp heat

Entering the dog days, the northern part of China enters the high temperature period, and many places in the south enter the rainy season. This climate is a "hotbed" of urticaria, and it is also the main reason for the high incidence of urticaria in summer.

Hot and humid weather is easy to damage the skin barrier and can't stop harmful substances such as allergens, irritants, bacteria and fungi. In the hot and humid environment, bacteria and fungi are easy to breed, and in addition, the strong ultraviolet rays of summer sunlight will cause certain irritation to human skin under direct sunlight. For some people with allergic constitution, sensitive skin or low immunity, urticaria is easy to occur.

One more thing, with the hot weather, the surface temperature of human skin rises and the water evaporates quickly, which will also make the skin dry and induce urticaria.

Second, eat and drink.

Seafood, barbecue, food stalls, cold beer, etc. They are all "frequent visitors" on the dinner table in summer, and many people even take turns putting these delicious foods into their stomachs. Studies show that foods rich in protein, seafood, especially irritating foods and some raw foods are easy to cause allergic gastroenteritis, which may lead to urticaria.

In addition, regular consumption of these foods will cause certain damage to the liver and gastrointestinal tract, leading to decreased immunity, more likely to cause allergic reactions, or make bacteria and fungi take advantage of it, thus inducing urticaria.

Third, there are many mosquitoes in summer.

Summer is the world of mosquitoes. Often when you think it doesn't exist, when you are not ready to kill mosquitoes, you will become the meat on the mosquito's plate. Then this is the main reason why you are targeted by urticaria. For urticaria caused by mosquito bites, you can use mosquito repellent, toilet water and mosquito killer to meet it all; And don't go deep into the grass.

How should urticaria appear in summer? Two aspects should be carried out at the same time:

The first is active treatment.

Antihistamines are important drugs for the treatment of various urticaria patients, which can control the symptoms of most patients. Although antihistamines cannot directly antagonize or neutralize histamine and prevent its release, they can compete with histamine and quickly inhibit the generation of wheal. There are many side effects of antihistamines, so it is best to choose the one with small side effects, especially for workers working at high altitude and drivers, who use it with caution and are prone to accidents due to drowsiness. Long-term use of one antihistamine is prone to drug resistance, and another can be used. Or alternatively or in combination. Children's drug resistance is greater than that of adults, so the relative dosage is also greater.

The onset of urticaria is an immune response caused by the stimulation of allergens, which leads to the abnormal increase of immunoglobulin E in the body. Repeated contact with allergens leads to a large number of IgE antibodies in the body, which attach to immune cells for a long time, leading to the secretion of inflammatory mediators such as histamine, which is harmful to itself. From the immunological point of view of urticaria, the fundamental treatment should be to control IgE and adjust the balance of immunoglobulin. At present, the treatment of urticaria mostly stays at the stage of inflammation such as antihistamine, and some people try to treat it by improving their own immunity, but allergy is not caused by low immunity, and the imbalance of five immunoglobulin secretion in human body is the root cause of the disease. At present, the treatment method of IgE anti-human antibody to solve urticaria in international immunology research is to reduce IgE antibody in human body by supplementing a large number of anti-allergic probiotics xinminkang, and to regulate immunoglobulin balance by stimulating interferon secretion, thus restoring human immune response.

The second is active prevention.

1, some patients with urticaria are allergic, so it is necessary to prevent them in daily life, reduce their exposure to allergens, such as ultraviolet allergy, sun protection, such as pollen allergy, and wear masks when going out.

2, light diet, do not eat spicy food.

3, proper exercise, enhance the body's immunity, so as to avoid urticaria recurrence.

4, you can't grab it at will. If the skin becomes itchy, don't scratch it at will. Many times, when I first scratch, I feel very comfortable. But the harder you scratch, the stronger the stimulation, which not only can't relieve urticaria, but also make the skin worse.

5. learn to decompress. If the body is under great pressure, it is also a very bad thing. If the pressure is high, it will affect the abnormality of the secretory nervous system, leading to the weakening of cell activity and the secretion of more histamine, or it will lead to the aggravation of urticaria and the skin becoming more and more itchy.
