A bad cough in bed is due to inflammation in the bronchial tubes. When you lie down to rest at night, the sympathetic nerves are excited and the secretions in the trachea flow backwards into the pharyngeal tube, which will stimulate the throat with itching and coughing symptoms. For coughing in bed, it is recommended to take busulfan anti-inflammatory oral liquid and cefixime capsule for anti-infection treatment. You should also take cough suppressant and phlegm-relieving medications such as Glycyrrhiza glabra Oral Solution and Cough Boosting Capsules to stop coughing. Usually try not to open the window when you sleep at night to avoid getting cold and wind. It is better to put your pillow higher to reduce the discomfort caused by coughing. During the coughing period, it is important to maintain a light diet, not to eat spicy and stimulating food, and to avoid exposure to irritating smells such as oil and smoke. Eating ice sugar and snow pear cream and Chuanbei honey water can also help to moisten the lungs and relieve cough.
