The main clinical manifestations of asthma include wheezing, coughing, shortness of breath, chest tightness, dyspnea, etc., and the attacks often occur at night or in the early morning. As the most common non-specific respiratory disease in childhood, asthma is often triggered by upper respiratory tract infections, allergen exposure, strenuous exercise, laughing, crying, climate change, and is characterized by sudden onset or exacerbation of exacerbations, most commonly at night and in the early hours of the morning, and markedly during the fall and winter seasons or seasonal changes, and may be relieved by drug therapy. The cause of asthma is complex, and is currently believed to be influenced by a variety of genetic and environmental factors. There are many triggers for asthma in children, including inhalant allergens, such as dust mites, animal dander, etc., ingested allergens, such as milk, fish, shrimp, eggs and peanuts, etc., as well as strong emotional changes, exercise and hyperventilation, cold air, occupational dust and gases, etc., which can trigger asthma. It is recommended to consult a doctor in time for pulmonary ventilation function tests, etc. If asthma is diagnosed, long-term standardized treatment should be prescribed by the doctor.
