1, the cause of urticaria is inseparable from diet. Fish, shrimp, crabs and eggs are the most common foods that cause urticaria. Some meat and some plant foods such as strawberries, cocoa, tomatoes, coffee, garlic and other condiments can cause urticaria.
2. The most common indoor allergen-dust mite. Dust mites are arthropods that feed on human dander and often live in sheets, blankets and quilts. In addition, dead corners and carpets in the house can also be their homes. According to foreign statistics, more than 70% families have dust mites. The most allergic thing is the excrement of dust mites-dung balls. Usually April-May and 9- 10 are breeding seasons, when the number of dust mites at home is the largest. Therefore, people who are allergic to dust mites have symptoms all year round and may get worse during the breeding season. Patients can manifest as urticaria, asthma, eye rhinitis, etc. And the symptoms tend to get worse after lying down at night.
3. Air-conditioned room. Now someone has urticaria and I don't know why. It may have a lot to do with your long-term expectation in an air-conditioned room. The air conditioner is cold, which is fatal to people who are afraid of cold, leading to small acne and obvious itching. Therefore, for people who are afraid of cold, it is not recommended to stay in an air-conditioned room for a long time, and don't set the temperature too low.
There are many mosquitoes. 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.
5, love to sweat when moving. It's summer and it's very hot. When you go out for a walk, the sweat will keep flowing downwards. This is also an important cause of urticaria. When people are hot and nervous, they will induce or aggravate the symptoms of urticaria. For this kind of people, summer is a disaster season, so it is suggested to improve the allergic constitution, fundamentally solve the problem, and let urticaria not happen again.
6, the mat breeds bacteria. In order to avoid the heat in summer, any method that can reduce the temperature will be used. Mat became the first heat insulation material. However, sleeping mats in summer can easily breed bacteria and then get them on the skin, leading to urticaria. Therefore, it is suggested to clean the sleeping mat with clear water every day to remove all sweat stains or dust, avoid the chance of skin contact with allergens and reduce the frequency of urticaria.
In summer, there are many allergens that can cause urticaria.
The first kind: pollen
Pollen spread in summer will cause skin allergy after direct contact with the skin, which will lead to urticaria.
The second type: dust mites in the air.
Dust mites floating in the air can cause urticaria. Although we can't see dust mites with naked eyes, dust mites do affect our skin.
The third kind: parasitic bacteria
There are many parasitic bacteria invisible to the naked eye on the daily necessities we usually use. These parasitic bacteria will affect our skin and cause urticaria, so we must pay attention to the disinfection and cleaning of daily necessities.
The fourth kind: parasitic bacteria in food.
Parasitic bacteria in food are more likely to enter our bodies, leading to allergies and urticaria.
Fifth: additives in food.
Although the additives in food are all edible additives, if they are not controlled in a proper range, they will also affect the health of friends and lead to allergies.
Sixth: interpersonal communication
If our friends or family members carry allergens, it will also lead to urticaria, so we should take precautions.
Only when the cause is clear and prevention is more important than treatment can prevention and treatment be better.
Dermatologists remind that prevention of urticaria is more important than cure. Looking for allergens, taking anti-allergic probiotics Xinmin Kang to regulate allergic constitution and stay away from allergens can effectively prevent urticaria from recurring. So, among so many allergens, how can urticaria patients accurately find their own allergens? Experts said that by recording the causes and laws of the disease in detail, possible allergic factors can be found out. At present, there are many methods to detect allergens in hospitals, such as prick test, patch test and blood test, which can detect 10-30 allergens.
It should be emphasized that allergens are not static, and the results of allergen testing can provide the basis for prevention and treatment within half a year. Patients with urticaria again after half a year should go to the hospital to re-test allergens in time, so allergic IgE is the focus.
At present, people only pay attention to the treatment of urticaria, but not the allergic reaction itself: the stimulation of allergens leads to the disorder of human immune function and 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 autoimmune reactions. From the immunological point of view of urticaria, the fundamental treatment should be to control IgE and adjust the balance of immunoglobulin. The patented anti-allergic strain of Xinmin Kang anti-allergic probiotics, through human and animal experiments, can reduce the IgE antibody in vivo and adjust the balance between immunoglobulin and allergic constitution by stimulating interferon secretion. The effective combination of antiallergic drugs and antiallergic probiotics can also produce ideal rehabilitation effect.
Because summer is wind-heat urticaria, it is very important to pay attention to "coolness" during nursing.
1, pay attention to the temperature conversion between cold and hot, and keep the room ventilated frequently to keep the air fresh. However, patients should stay in bed and cover themselves with quilts, and their clothes should be moderate to avoid direct blowing.
2, Tang Yi warm clothes, eat cold food properly, such as taking mung bean porridge, glutinous rice soup, eating radish, Artemisia annua, cucumber and other vegetables, drinking mint water, honeysuckle dew and other cool drinks, dispelling wind and clearing heat; Avoid helping fire and hot food. Avoid eating raw cold, and drink warm water or cold drinks when you are thirsty.
3. When taking a bath, the water temperature should not be overheated. Don't rub your skin hard to avoid sweating after washing. Don't scratch, scald with hot water, pepper water, salt water bath and other improper methods to stop itching.
4. It is not advisable to use external drugs with strong irritation to avoid aggravating skin lesions.
