Currently we can cure psoriasis, but the disease is prone to recurrence. If patients can take care of themselves according to the following advice, I believe that they will be able to reduce or mitigate the recurrence of psoriasis. 1, patients should maintain the right attitude towards their disease, both to actively treat and not to carry the burden of thought. The spirit should be optimistic and emotionally stable, and those with type A personality should make themselves gradually change to type B personality. We should avoid tension and transitional exertion, combine work and rest, take sufficient rest, live a regular life, have comprehensive nutrition, and insist on physical exercise to maintain a good health condition of the whole body for a long time. This is the basis for reducing and mitigating the recurrence of psoriasis. 2.It should be recognized that active treatment is never transitional treatment or haphazard treatment. Treatment should be scientific and moderate. The physician should give the treatment scientifically and moderately according to the patient’s onset trigger, onset season, onset site, onset degree, accompanying symptoms and past treatment measures; the patient should implement the prevention and control measures according to the guidance of the experienced physician. Do not treat indiscriminately, for some drugs that are not yet known, to do some research and consultation first, do not use easily.
