The occurrence and recurrence of psoriasis are affected by a variety of factors, some patients develop psoriasis after upper respiratory tract infection, some patients develop psoriasis due to excessive mental tension, while some patients are allergic to a certain kind of food, which requires patients to learn to summarize themselves, research and explore the law of onset, try to find the specific reasons for each onset, pay attention to it in future life and reduce the chance of recurrence. A, recurrence triggers 1, infection: local infection foci is an important cause of psoriasis, especially after the cold, complications tonsillitis, bronchitis, need to be actively treated to shorten the course of the disease as much as possible, or cause a relapse, so that the previous treatment was abandoned. And if the tonsils are repeatedly inflamed and closely related to psoriasis attacks, tonsillectomy can be considered, which is especially important for adolescent patients. (If you intend to tonsillectomy must be carried out after the healing of psoriasis, otherwise it will aggravate the disease) 2, allergic factors: is one of the important triggering causes of psoriasis. Due to diet or taking drugs, or contact with a substance and allergic, can often induce the occurrence of psoriasis. After each relapse, patients need to carefully recall what has been taken recently, what drugs were taken, or contact with a certain chemical substance, thus making the skin red and itchy, followed by psoriasis lesions, then this substance should try to avoid contact in the future. 3, damp and cold: the number of psoriasis induced by wind and cold invasion is more, the facial rash is mostly stimulated by cold wind, so attention should be paid to the protection of the face in winter; damp and cold living environment can make the disease occur or aggravate, so patients should try to avoid big cold and hot stimulation of the skin, and keep the room ventilated, dry and warm. 4, mental factors: in recent decades, there are many literature data show that psoriasis is a psychosomatic disease of unknown cause, some patients have more or less low self-esteem, anxiety, fear, suspicion, irritability and other personality characteristics, or due to overwork, stay up late, family disputes, the death of relatives, economic problems, etc., so that patients are overly nervous, emotional depression, can cause a series of psychological reactions, resulting in endocrine disorders, immune function decline, thus promoting the development of the disease. This can cause a series of psychological reactions, leading to endocrine disorders and a decrease in immune function, thus promoting the occurrence and development of psoriasis. Therefore, in case of irresistible natural or man-made disasters, patients should try to control their emotions, try to keep their mood calm, first understand the surrounding things correctly, ensure sufficient sleep, and take sedatives in moderation when necessary. In short, in order to reduce recurrence, psoriasis patients should, under the guidance of doctors, find out the law of onset by themselves, under what circumstances does psoriasis recur, what do they eat? What season does it recur? It varies from person to person, and only by being good at summarizing the rules of life and actively eliminating the triggering factors can we effectively prevent psoriasis recurrence. Second, coping strategies 1, maintain a positive and optimistic mood: establish confidence in overcoming the disease, do not carry a heavy burden of thought once you suffer from the disease. As long as the mood open Lang, emotional stability, work and rest, and have a good routine, early rest, do not stay up late, sufficient sleep is very beneficial to the recovery of psoriasis, you can get twice the effect with half the effort. 2, find out the cause, try to avoid: if there is tonsillitis, pharyngitis, upper respiratory tract infection, should be actively treated. Avoid all kinds of strong physical and chemical stimuli, such as hair dye, tattoos, etc. 3, do not abuse drugs: patients should be treated regularly, do not abuse drugs. 4, diet should be rationalized: do not be picky, not partial, not too full, not diet. Avoid smoking and alcohol, can eat more beans, coarse grains, fresh vegetables, fruits and other high-protein, low-fat, vitamin-rich foods. 5, keep the skin clean: in the treatment process, patients can take a bath once a week, which can not only remove the thick scales, clean skin, but also improve microcirculation, promote metabolism (because the use of topical drugs is best not to take a bath every day, every day bath easy to make the skin dry, and easy to catch a cold). After healing, you can often bathe, keep the skin clean, the prevention of various skin diseases is greatly beneficial. 6, consolidation treatment, essential: some patients think that as long as the psoriasis lesions recede, even if the cure is no longer treated. In fact, the remission of lesions only means the remission of symptoms, while the internal environment (cellular immunity, humoral immunity, microcirculation, etc.) is not necessarily adjusted to normal, at best, it can only be considered clinically cured, not completely cured, and at this time, if treatment is stopped, it is easy to relapse in winter and spring, and consolidation treatment is carried out according to the differences in individual conditions. 7, more outdoor exercise: more activities, moderate sweating, more sunshine. Enhance physical fitness and improve the body’s ability to resist disease. It is medicine is not as good as food, food is not as good as exercise. Only a strong body is the cure for the disease.
