When summer comes, my skin becomes red and itchy. Why?

Why do many people get urticaria in hot summer?

1. Caused by improper diet in summer nights. Foods that generally cause urticaria are fish, shrimp, crab, and eggs. Certain meats and some plant foods such as strawberries, cocoa, tomatoes, coffee, or garlic and other condiments can cause urticaria.

2. The most common indoor allergen - dust mites. Dust mites are arthropods that feed on human skin flakes. They often live in bed sheets, blankets and quilts. In addition, they can also live in dead corners and carpets in the house. According to foreign statistics, more than 70% of households have dust mites. The most allergenic is the fecal pellets produced by dust mites. Usually April-May and July-October are their breeding seasons, when the number of dust mites in the home is greatest. Therefore, people with dust mite allergy have symptoms all year round, which may worsen during the breeding season. Patients may present with urticaria, asthma, ophthalmitis, etc. Symptoms often worsen after lying down at night.

3. Always stay in an air-conditioned room. Now there are people who develop hives and don’t know the cause. It may have a lot to do with your long stay in an air-conditioned room. The air conditioning is relatively cold, which can be a fatal injury to people who are sensitive to cold, causing small bumps and obvious itching. Therefore, for people who are sensitive to cold, it is not recommended to stay in an air-conditioned room for a long time and do not set the temperature too low.

4. There are many mosquitoes in summer. Summer is the world of mosquitoes. Often when you think they don’t exist or when you don’t have a mosquito killer ready, you become the prey of mosquitoes. Then this becomes the main reason why you are targeted by urticaria. For urticaria caused by mosquito bites, use all imaginable mosquito repellent liquid, toilet water, and mosquito killers; and do not go deep into the grass.

5. Move and sweat. It's summer, the weather is hot, and if you go out for a walk, sweat will continue to flow down. This is also an important cause of urticaria. When people are exposed to heat or stress, the symptoms of urticaria will be induced or worsened. For such people, summer is the season of disaster. It is recommended to improve the allergic constitution and fundamentally solve the problem so that urticaria will no longer occur.

What are the symptoms of summer urticaria?

At the beginning of the disease, patients with urticaria usually experience itching symptoms on the affected part of the skin, and then wheals quickly appear. Some patients will also experience other systemic symptoms within a few hours after the rubella appears, such as general discomfort, head pain, or body fever.

The rubella patches that appear on patients are generally flat and appear red, yellowish or pale in color. Sometimes, the shape of the wheal is annular, which can be called annular urticaria. Several adjacent annular lesions can be connected or fused to form a hive.

Due to the existence of petechiae in the patient's damaged center, the kidneys and gastrointestinal bleeding may occur together, which is hemorrhagic urticaria. When blisters occur in a wheal, it is called vesicular urticaria. If bullae appear, it is more serious and is usually called bullous urticaria. Sometimes, blisters or bullae occur on skin that appears to be normal, but often there is redness. This type of wheal is more likely to occur in children.

How to deal with the occurrence of urticaria in summer

1. Allergic urticaria is caused by allergies. Patients must stay away from allergens in daily life. Drugs that cause it should be discontinued. Allergy medicine. For those who are allergic to food, after finding out the food they are allergic to, do not eat this food again, such as clams, shrimps, crabs, etc.

2. Antihistamines are important drugs for the treatment of various urticaria patients. They can control the symptoms of most patients. Although antihistamines cannot directly fight or neutralize histamine, they cannot prevent histamine production. It is released, but has a competitive effect on histamine, which can quickly inhibit the production of wheals. Antihistamines have various side effects. It is best to choose those with fewer side effects. Workers such as workers and drivers working at high altitudes should use them with caution as they can easily lead to accidents due to drowsiness. Long-term use of one antihistamine drug can easily lead to drug resistance, so you can try another one. Either alternately or combined applications. Children have greater drug resistance than adults, so the relative dosage is also greater.

3. Due to the stimulation of allergens, the immune function of the human body is disordered, resulting in an abnormal increase in immunoglobulin E in the body. Repeated exposure to allergens causes the body to produce a large amount of IgE antibodies and attach to immune cells for a long time, resulting in The secretion of histamine and other inflammatory mediators damages the autologous immune response. From the immunological point of view of urticaria, the fundamental treatment should be to control IgE and regulate the balance of immunoglobulins. At present, the treatment of urticaria mostly focuses on anti-inflammatory drugs. In the inflammatory stage such as histamine, some people will try to treat it by improving their immunity. However, allergies are not caused by low immunity. The imbalance of the body's five immunoglobulin secretions is the fundamental cause of the disease. Currently, international immunology research has solved The treatment method for IgE anti-human antibodies that cause urticaria is to supplement a large amount of human anti-allergic probiotic Xinminkang to reduce the IgE antibodies in the body and regulate the balance of immunoglobulins by stimulating the secretion of interferon, thereby restoring the body's immune response to the correct state.

4. Since mosquito bites cause urticaria, there are many anti-mosquito bite products available on the market for citizens to choose from. The simplest method is to apply alkaline soapy water or salt water to the wound. Rinse the wound to soften redness and relieve itching.

"Experts said that citizens can also choose to eat more alkaline vegetables, so that the body's body and blood will become slightly alkaline. Not only will mosquitoes not like bites, but the bites will not be itchy even after being bitten.
