Maintain a good state of mind and awareness of the disease: Psoriasis is a common disease and a multi-morbidity that endangers people’s physical and mental health. China now has more than 6 million patients with psoriasis. Because psoriasis has a long course, is prone to recurrence and occurs on the surface of the body in a way that hinders the beauty, many patients are under great psychological pressure and have a heavy mental burden. Some patients mistakenly believe that psoriasis is an incurable disease, and some people mistakenly believe that the disease is contagious and discriminate against patients. Therefore, the psychological pain of patients is often greater than the symptoms of their skin lesions. There are different misconceptions among the general public and patients. Many patients are under great psychological pressure after doctors diagnose them with psoriasis, and are influenced by traditional concepts and public opinion, believing that they suffer from an incurable disease, and are depressed and suppressed, which is not only detrimental to the remission and recovery of the disease, but also can aggravate the disease and make the treatment resistant. Patients are too pessimistic and their physical and mental health is in a state of disgusting cycle. The current psoriasis medical market is very confusing, all kinds of media and even in the streets and alleys of the treatment of psoriasis advertising overwhelming, abound, some “wandering doctor”, even not at all dermatologists, driven by economic interests, using the psychology of patients want to cure, claiming to be “experts “, “specializing in the treatment of psoriasis”, cheating patients and profiteering, causing a lot of physical and psychological injuries of medical origin and a huge economic burden to patients. Many psoriasis patients and their families are poor in knowledge about psoriasis, blindly pursue the root cure, gullibly believe in some advertising propaganda and throw themselves at doctors indiscriminately, and the phenomenon of aggravating the disease and even causing serious consequences by mis-treatment and drug abuse is quite serious. A survey conducted by the Institute of Dermatology of the Chinese Academy of Medical Sciences shows that 58.6% of the 320 psoriasis patients do not know about psoriasis, 8.6% consult doctors about the knowledge, 89% do not read the scientific knowledge of psoriasis, 24% believe that it can be cured, 72.6% believe in various advertisements and have received treatment from individual doctors. The percentage of those who have received treatment from individual doctors is 65.7%. Therefore, the prevention and control of psoriasis must strengthen the popular education of psoriasis-related knowledge, and regular medical treatment and good health education can make the condition improve or even cure. Patients should read more psoriasis science manuals, as well as have the guidance and follow-up of an experienced and responsible specialist dermatologist. Medication needs to know: Patients should not believe in the propaganda of “cure for all”, and should not seek medical help in an emergency, as there is no special medicine for psoriasis. You should go to the dermatology department of a regular hospital, and regarding corticosteroids and immunosuppressive drugs, you should use them under the guidance of a skin specialist. Avoid external use of irritating drugs during the acute period to avoid triggering heavy psoriasis. Avoid hot water and soap baths, scratching or mechanical stimulation to prevent aggravation of lesions and itchiness. Patients should pay attention to avoid the application of some drugs that may induce or aggravate psoriasis, such as corticosteroid, insulin, tetracycline, lithium, antimalarials, ampicillin, anti-inflammatory pain, pautaceone, acetylsalicylic acid, interferon, etc. Diet and lifestyle habits: Patients eat a reasonable diet, to consume the right amount of water, protein, vitamins and trace elements, etc.. Eat less beef and mutton because of their high arachidonic acid content. Spicy food should be avoided, because spicy food can stimulate the body, make the skin blood vessels dilate and congestion, and induce or aggravate psoriasis. Psoriasis is a chronic recurrent disease, patients can pay attention to the food that may cause the attack or aggravation of the disease in daily life, and should try to avoid the suspicious food. Pay attention to scientific diet and avoid too strict taboos to avoid causing serious malnutrition. Quit smoking and limit alcohol. Smoking and alcoholism play a role in triggering and aggravating psoriasis. Studies have found that the number of psoriasis patients who smoke and drink and the severity of the disease are obviously related, and the greater the number of smoking and drinking, the more serious the onset of the disease. Alcohol consumption can also hinder the efficacy of psoriasis, as alcohol may affect the absorption or metabolism of some drugs. Therefore, psoriasis patients should be advised to avoid smoking and alcohol, or at least to drink less and not to drink alcohol. Reasonable rest and exercise: relaxation. Tension can lead to a sudden increase in psoriasis. Inevitably, life can sometimes make you emotionally tense, and in order to ease the exacerbation of the condition, you need to find a way to relax. One study found that patients who underwent light therapy recovered faster if they listened to meditative relaxation tapes. Some other effective relaxation methods used by psoriasis patients include: hypnosis, massage, reverie, tai chi and yoga. Patients should pay attention to the combination of work and rest and should not overexert themselves. Keep the living environment neat, dry and warm, and avoid humidity. Encourage patients to take appropriate physical exercise to enhance physical fitness, pay attention to cold and warmth, timely increase and decrease clothing, and prevent colds, as 6-20% of patients’ morbidity or aggravation is closely related to colds. Some doctors in China have adopted the method of “exercise and sweating”, allowing winter-type patients to exercise for half an hour every day since the end of autumn to make their bodies sweat slightly, which has the effect of preventing recurrence and aggravation. Pay attention to self-protection in daily work and life, and try to avoid trauma to prevent recurrence or isomorphic reactions caused by trauma. Patients are encouraged to actively participate in cultural, sports and social activities to shorten the distance between them and others, to cultivate optimism, to form good psychological qualities, and to improve their psychological tolerance of the disease and other difficulties. Patients are expected to voluntarily adopt health-friendly behaviors, change poor lifestyles, reduce morbidity, prolong remission, reduce complications, avoid aggravation and transformation, and improve patients’ quality of life.
