The tip of lying down to stop coughing is lacking scientific basis. The correct approach is that the cause of the cough should be identified and then treated. Common causes include colds, pneumonia, chronic pharyngitis, tuberculosis, lung tumors, gastroesophageal reflux disease and so on. Treatment includes cough suppression, anti-infection, anti-tuberculosis, anti-tumor treatment and inhibition of gastric acid. 1. Colds: Coughs caused by colds can usually be relieved by resting, and when the cough is severe, cough suppressants such as compound licorice tablets can be taken to relieve the cough. 2. Pneumonia: Cough medicine for pneumonia requires anti-infection treatment such as cefixime and azithromycin. 3. Chronic pharyngitis: chronic pharyngitis can also lead to coughing, at this time you can take watermelon cream and so on to ease the seriousness of the need for nebulization treatment. 4. Tuberculosis: Cough caused by tuberculosis should be actively treated with anti-tuberculosis therapy, such as isoniazid, rifampicin and so on. 5. Lung tumor: cough caused by lung tumor should be treated with anti-tumor therapy such as surgery, radiotherapy and chemotherapy after identifying the specific type of tumor. 6. Gastroesophageal reflux disease (GERD): cough caused by GERD can be treated with drugs that inhibit gastric acid, such as omeprazole, ranitidine, etc., and those that promote gastric motility, such as domperidone and mosapride. There may be other reasons for lying down and coughing, so there is no such thing as a coughing trick, you should go to a regular hospital, improve the relevant examination, and give targeted treatment and therapy after clarifying the cause of the disease. Should avoid blindly self-medication.
