Cough is body’s response to irritants in the throat and airways. The irritants end up stimulating the nerves in the airways or respiratory tract, and these impulses travel to the brain, which sends back signals to the throat and lungs, resulting in cough. Then the cough clears the irritants, secretions, foreign particles and microbes from the airways. There are several causes for cough, including acute sinusitis, asthma, bronchitis, heart failure, influenza, tuberculosis, pneumonia, and lung cancer.
The cough may or may not be accompanied by sputum. If the cough occurs without any sputum production it is called dry cough. The cough can occur any time of the day or night. If the cough is persistent or frequent, accompanied by other symptoms like fever or breathlessness and sputum production, then it could be indicative of an underlying serious lung or heart disease.
In that case you have to consult your doctor. There are several home remedies for dry cough. You can try them individually or severally at once. Most of these remedies work by coating the back of your throat or soothing the cough receptors in the airways.
