Psoriasis is a lifelong, easily recurring inflammatory skin condition for which there is no cure with specific medications. The disease is not fatal and current treatment measures are long-term control of the inflammation with the goal of improving the patient’s quality of life. In addition to the medication prescribed by the doctor, the daily care of psoriasis patients is also very important for the control of the disease and its improvement. As we all know, the most painful experience brought about by psoriasis is the unbearable itching. Dr. Chen pointed out that the most taboo thing at this time is scratching and tearing away the dead skin, and these actions tend to lead to skin breakage and further deterioration of the condition. In this case, the patient can use the palm of the hand to pat the itchy area, while you can use a wet paper towel to cover the affected area, if the use of light salt water to wet the affected area is also very effective. To avoid itching, patients should wear loose, breathable cotton clothing to keep the skin cool, and insist on using moisturizers. Patients are advised to take a daily bath, which not only washes away the flakes to ensure cleanliness, but also promotes blood circulation to the skin, which helps the recovery of the disease. Bathing should use 36-38 ℃ warm water, too hot instead of stimulating the skin; lotion should choose fragrance-free, preservative-free, and at the same time has exfoliating and moisturizing effect, do not rub the bath, shampoo to pay attention to gentle action; after the bath to use a cotton soft towel to pat dry or dip dry skin, and finally apply skin moisturizer. Patients with sensitive skin areas such as the face, scalp and groin can choose tacrolimus ointment, which is a hormone-free preparation; it will not lead to side effects such as skin atrophy. Usually cooking needs to avoid frying or pan-frying to prevent spattered oil spots from damaging the skin, while oil fumes are also irritating; male patients should use electric razors to avoid having their faces scraped. Patients with thicker skin on the palms of their hands or feet are advised to use hormonal ointments; they should also avoid friction in their lives, such as wearing gloves when doing housework or other tasks, and soaking their hands and feet in salt water every day. If the diseased area is nails, special attention should also be paid to the fact that the symptoms of this type of psoriasis are not easy to control and treatment takes 3-4 months, and it is likely that systemic oral medications such as methotrexate and Avia are needed; meanwhile, patients should be further examined to determine whether it is arthritic psoriasis. Patients with psoriasis can eat high-protein, vitamin-rich foods such as tofu, vegetables, fruits, etc. Every day, it is recommended to eat less meat, fish and shrimps, but if there is no clear food allergy, there is no need to abstain from eating them. Therefore, patients should pay attention to quit smoking and limit alcohol. Maintaining a good mood is also very helpful to the relief of the disease, and a healthy and full mood can help the recovery of skin damage and improve the efficacy of treatment. Because mental stress is also an important cause of psoriasis, some minors (those with a genetic predisposition) develop skin erythema and start to develop psoriasis because they are too stressed before the “junior high school” or midterm exams. Itchy and painful skin of psoriasis patients can easily lead to irritability, and high psychological stress can in turn aggravate the condition or lead to relapse, resulting in a vicious circle. In order to maintain a good mood, it is recommended that patients often participate in less intense physical activities, which can enhance physical fitness and speed up blood circulation, as well as relieve mental stress; work also try not to work too hard to prevent mental tension and ensure normal work and rest. Although this disease has a certain relationship with heredity, patients are not advised to hide it when they fall in love, but need the strong support of their loved ones to face it together; otherwise, it may lead to family disharmony or even marriage breakup after marriage, especially during the preparation period.
