Why is psoriasis heavy in winter and light in summer? The actual reason for this is because of the winter climate. The reason for this is the fact that it is not a good idea to have a good time. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. A large number of literature reports and clinical observations also believe that the occurrence, aggravation, recurrence or improvement of psoriasis does have a close relationship with the season, the general rule is that the onset of winter, or aggravation and recurrence of the most people, to the summer climate after the warming of the skin lesion treatment is fast, short course of treatment, the best effect, the light condition of patients in this season skin lesions can also be self-receding. The patient’s morbidity pattern has changed due to the fact that psoriasis is easily recurring and the patient has been treated with multiple medications internally and externally for a long time. Therefore, in the process of treating psoriasis, it is important to consider the relationship between the disease and the seasons, and the seasons and the effectiveness of treatment. Since some patients have a certain natural pattern of onset, it is important to be cautious with medication when treating, and to minimize or not use drugs with large side effects or strong irritants, so as not to change the pattern of the disease due to inappropriate medication, causing aggravation of the disease, prolonging the course of the disease, and causing undue suffering to the patient. The reason is that some patients with psoriasis have a natural pattern of aggravation, recurrence or remission in different seasons, and some people also call the onset of aggravation or recurrence in the cold season of autumn and winter, and the reduction or remission in summer as winter-type psoriasis. In the winter, it is called summer psoriasis. According to domestic statistics. Psoriasis begins most often in the spring, followed by summer, winter, and autumn. In general, winter and spring are the main seasons for the onset and recurrence of psoriasis. After mastering and understanding the relationship between psoriasis and the seasons, one can take appropriate measures according to the changes in the skin lesions of patients in different seasons to speed up the fading of the skin lesions and shorten the treatment time. The improvement of the disease in summer and autumn does not mean that the toxins in the body disappear, but rather that the toxins are relatively less active, so it is more important to seize the time to treat it so that there is no chance of recurrence and aggravation before winter and spring come, so that the patient can recover as soon as possible.
