Recently, there have been frequent warnings of low temperature and cold waves in China. Due to the decrease in air humidity, an increase in allergens, and a larger temperature difference between morning and evening, winter has become a high-risk period for asthma. How do asthma patients survive the winter safely? Experts suggest that in order to achieve scientific and standardized disease management, it is also important for asthma patients to receive standardized treatment in addition to taking daily protective measures. Asthma is one of the main chronic diseases that affect the health of the general public in China. An epidemiological survey data shows that there are approximately 45.7 million adult asthma patients in China, and the incidence of asthma increases with age. Huang Kewu, Chief Physician of the Respiratory and Critical Care Medicine Department at Beijing Chaoyang Hospital affiliated with Capital Medical University, stated that the incidence of asthma in China is increasing year by year. At the same time, 55% to 70% of asthma patients are in a state of poor control, affecting their daytime activities, causing breathing difficulties, nocturnal distress, the need for emergency medication, and a serious disease burden. "In response to this situation, we need to promote precise and standardized diagnosis and treatment for patients, help them improve symptoms and disease control levels, reduce the risk of future acute attacks, and further alleviate the disease burden on patients in China," said Huang Kewu. With the continuous deepening of research on asthma, the underlying inflammatory mechanisms have gradually emerged. Research has found a close correlation between type 2 inflammation and the occurrence and development of asthma. Since 2019, the Global Initiative for Asthma Prevention and Treatment (GINA) guidelines have classified asthma into type 2 inflammation and non type 2 asthma. Type 2 inflammation has also become an important reference for medication and disease management in asthma patients. "For type 2 asthma patients, cold weather and air pollution are triggering factors, and the deeper underlying pathogenesis may be type 2 inflammation." Zhang Min, Director of Respiratory and Critical Care Medicine at the First People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, said that when choosing treatment plans, it is also necessary to start from the root cause and carry out targeted treatment to better control asthma attacks. Nowadays, glucocorticoids and β Various drugs such as 2-receptor agonists. In recent years, some new therapies have also been applied to the treatment of asthma patients, promoting long-term effective disease control. "At present, in clinical practice, it is possible to identify whether a patient belongs to type 2 asthma by using blood routine or FeNO (exhaled nitric oxide) detection methods when conditions permit." Zhang Min said. Su Nan, chief physician of the Department of Respiratory and Critical Care Medicine of the China-Japan Friendship Hospital, said: "In terms of the choice of treatment plans, it is recommended that asthma patients choose the appropriate treatment drugs under the guidance of doctors according to different disease conditions of individuals. If the symptoms of patients with type 2 asthma still cannot be controlled after the application of basic treatment plans such as inhaled hormones, it is necessary to carry out individualized treatment for the causes of type 2 inflammation." Su Nan reminded that in addition to adhering to long-term standardized treatment, asthma patients themselves should also improve their awareness of asthma diseases and pay attention to protection. In winter, on the one hand, it is important to keep warm and prevent cold air from irritating the trachea, while also avoiding respiratory diseases such as influenza; On the other hand, it is also necessary to maintain indoor air circulation, reduce exposure to allergens such as dust, smoke, and pollen, in order to maintain good health and safety
