Coughing is the body's way of removing foreign material or mucus from the lungs and upper airway passages or of reacting to an irritated airway.
Coughs have certain traits you can learn to recognize. A cough is only a symptom, not a disease. Often, you can't tell how serious the problem is until you also look at the other symptoms.
A productive cough produces phlegm or mucus (sputum). The mucus may have drained down the back of the throat from the nose or sinuses. Or it may have come up from the lungs. In most cases, you shouldn't suppress a productive cough. The cough clears mucus from the lungs. There are many causes of a productive cough, such as:
A nonproductive cough is dry. It doesn't produce sputum. A dry, hacking cough may occur toward the end of a cold or after exposure to an irritant, such as dust or smoke. There are many causes of a nonproductive cough. They include:

Using an antibiotic when you don't need it exposes you to the risks of an allergic reaction and antibiotic side effects, such as nausea, vomiting, diarrhea, rashes, and yeast infections. Antibiotics also may kill helpful bacteria and encourage the growth of dangerous antibiotic-resistant bacteria.

Coughing is your body's way of removing foreign substances and mucus from your lungs and upper airway passages. Productive coughs are often useful. Don't try to stop a productive cough. Sometimes, though, coughs are severe enough to impair breathing or prevent rest. Here are some things you can do at home to help you feel more comfortable when you have a cough.
Fluids may help thin mucus and soothe an irritated throat. Honey or lemon juice in hot water or tea may help a dry, hacking cough.

Try a vaporizer or humidifier to add moisture to the room. Warm or cool mist may help relieve symptoms. Follow all cleaning instructions and precautions for the machine.
