Chronic bronchitis is a chronic inflammation of the respiratory system, which tends to be prolonged and recurrent. For those suffering from this disease, it is primarily important to quit smoking, which is a crucial preventive measure against acute attacks of chronic bronchitis. It is also essential to control occupational or environmental pollution to avoid the irritation of harmful gases such as dust and smoke. Additionally, it is advisable to strengthen the body through regular exercise, enhance immunity, and increase cold resistance. It is recommended to wash the face with cold water all year round to enhance the skin's ability to prevent and fight diseases. During the flu season, getting a flu vaccine to prevent the onset of a cold, reinforcing dietary hygiene, and enhancing health education is also advised.
