When summer comes and temperature rises, do you feel irregular blisters all over your body while you are exercising, sweating or facing wind, and you may also have obvious itching? It could be hives.
The concept of urticaria
Urticaria is commonly known as "urticaria" and is usually divided into acute and chronic:
● Acute recurrent attacks within 1-6 weeks;
● Chronic ones will last more than 6 weeks or even several years, and recurring attacks cannot be completely cured.
The onset is as sudden as wind, but blister gradually disappears over several hours, and wind passes without a trace, usually within 24 hours. However, when old blisters disappear and you think you can breathe a sigh of relief, new blisters may reappear, one after other. After repeated attacks over a period of time, it will subside.
If situation described above occurs repeatedly, at least 2 times a week for more than 6 weeks, it can be regarded as chronic urticaria. Systemic symptoms of chronic urticaria are mild, but continue for several months or years repeatedly, sometimes to a greater or lesser extent.
Why it's easy to get hives in summer
There are many complex causes of hives, but main underlying causes include:
The climate in summer is hot and humid, and various bacteria in air are active and active, which makes human body susceptible to bacteria, mold, viruses or parasites, and can also stimulate immune system, cause an immune response, and cause allergic symptoms.
In summer, excessive sweating is also an important cause of hives. Symptoms may be triggered or aggravated by heat, stress, or exercise. In some people who are sensitive to sunlight, cold, and heat, incidence of hives increases when exposed to these external stimuli.
Nutritional factors/physical factors
Due to hot summer weather, some irritating, damp and cold foods should be eaten less. In summer, following foods often cause allergies: seafood, nuts, mangoes, strawberries, alcoholic soft drinks, etc. Common food allergens. People prone to hives should pay attention to relationship between their body and diet, and pay attention to avoiding allergens.
Some people have allergies, and in summer temperature is high, and many things can become allergens. Hand scratching can cause a large area of red rash. Therefore, people prone to allergies should pay special attention in summer so as not to cause more harm to body.
Allergens such as inhalation of pollen, mold spores, dust, animal hair, insect excretions or particles, etc. can also cause allergies.
Common allergic drugs such as anti-inflammatory drugs (such as aspirin), antibiotics, etc. But not only drugs can cause allergies, but when adding nutritious foods, we also need to pay attention to whether ingredients may have ability to allergies.
Combined with above
Urtic patients should be treated according to their own initial characteristics and guidelines
Targeted prevention and prevention
Contraindications for itching with urticaria:
Don't Scratch: Scratching area raises temperature, causing blood to release more histamine, and more you scratch, more itchy.
Do not apply hot compresses. Using hot water compresses or scalding baths may temporarily relieve local itching, but will dilate blood vessels and release more histamine.
Don't take it lightly: Don't assume hives will come and go quickly, and ignore them. There are many etiologies of disease, so it is necessary to establish correct understanding, and if disease occurs, promptly seek diagnosis and treatment from a dermatologist.
Principles of treatment of urticaria
1. Timely treatment to prevent relapse
Chronic urticaria is defined as urticaria that lasts more than 6 weeks. If you do not pay attention to this at first and do not strictly standardize treatment, this will lead to repeated attacks of disease. If time does not intervene, frequency of relapses will increase, complexity of treatment will also increase, and risk of complications will also increase.
2. Sufficient time and dose
You can't get sick today, cure it today, and forget about it tomorrow when you feel better tomorrow. It is necessary to continue treatment according to cycle and course of treatment so that concentration of drug in blood is within therapeutic limits, instead of "fishing for three days and drying net for two days." Be careful when lowering dose and stopping medication!
3. General concept
Treatment for hives cannot just relieve itch. If you want to be happy for a while, if you don't cure itch completely, it will only lead to repeated attacks. Conventional antihistamine therapy is just a way to suppress symptoms, not a once and for all solution.
The key to treatment of skin diseases is not only simple reduction of symptoms, but also destruction of pathogens hidden under symptoms, one by one. Therefore, in treatment of urticaria, it is very important to choose right method and understand principle of treatment.
