My nose is very sensitive in cold weather. What should I do? How to prevent and treat it?

Prevention of chronic rhinitis, focusing on the treatment of acute rhinitis. Acute rhinitis will often turn into chronic rhinitis if it is not treated in time or thoroughly. Acute rhinitis is caused by respiratory virus infection, and prevention should focus on the following points: First, avoid various factors that lead to the decline of human resistance, such as excessive fatigue, lack of sleep, colds, drinking and smoking. This is because when the human body's resistance drops, the adjustment function of nasal mucosa is poor, the defense function is low, and the virus invades because of deficiency. Secondly, we should persist in physical exercise and enhance physical resistance. Exercise such as running in the morning, cold water bath or washing your face with cold water can strengthen your physique, improve your tolerance to cold and improve your adaptability to harsh conditions. At the same time, we should actively treat upper respiratory diseases and other systemic chronic diseases. In addition, Chinese herbal medicines can also be used for prevention. After catching a cold, you can take ginger and brown sugar water as soon as possible to drive away the "cold evil". During the cold epidemic, Chinese medicines such as Schizonepeta tenuifolia, Saposhnikovia divaricata, Radix Isatidis and Glycyrrhizae can be taken to reduce the incidence rate. During the cold season in autumn and winter or during the cold epidemic, wear masks when going out, avoid public meetings, go to public places as little as possible, and isolate patients. For polluted rooms, white vinegar fumigation can be used for air disinfection. Special note: Chronic rhinitis can be caused not only by the untimely and incomplete treatment of acute rhinitis, but also by the stimulation of chronic physical and chemical factors and improper medication. Therefore, when preventing chronic rhinitis, we should pay attention to the osmotic pressure, PH value and concentration of nasal drops. We should not abuse nasal drops for a long time, but use them correctly according to the guidance of specialists, so as not to cause drug-induced rhinitis or aggravate the pathological degree of the original rhinitis.
