I am allergic when the weather is cold. What should I do? Thank you for your questions.

Your condition is cold urticaria. The disease is mainly a physical problem, which can cause autoimmune dysfunction due to mental, environmental, fatigue, infection and other factors, leading to increased skin or systemic sensitivity. Wind (mainly cold air), cold air, cold water, food, etc. Are just one of the physical sensitization factors that cause allergies, which are easy to aggravate in winter. Although most allergic diseases are easily repeated, they still have certain regularity, and they are psychosomatic diseases related to mental psychology and neurovascular reactions. But many laws are highly personalized, and everyone may have some differences. Therefore, on the one hand, we should try to avoid possible causes of sensitization, on the other hand, we should adhere to regular treatment in treatment. After the symptoms disappear, it is still necessary to consolidate one stage of treatment and consider drugs to improve and regulate immune function. And it is best to start taking medicine one month before the onset, which is also one of the important means to reduce the incidence and prevent problems before they happen. Traditional Chinese medicine has certain advantages in regulating physique and improving allergic state.
