Cleaning and bathing: psoriasis patients should take a moderate bath, avoid excessive hot water scalding, avoid scrubbing hard; usually use warm water, choose to use some mild moisturizing body wash to moderately clean, you can take more baths or hot spring baths, which is more beneficial to the repair of skin lesions, because the scales are reduced and the water content of the skin is increased after bathing, which is beneficial to the absorption of topical drugs and thus better play the effect of drugs. Because of the abnormal barrier function of the skin of psoriasis patients, some mild moisturizers should be used after the bath. Dressing: psoriasis patients should wear clothes, especially underwear, should choose breathable, sweat-absorbing, light-colored, cotton-based clothing, preferably with no static electricity, no color loss, in order to reduce the frictional stimulation of clothing on the skin, thereby reducing itching and facilitating the recovery of the disease.
