Natural methods for treating and managing a dry cough depend on the underlying cause of the cough. Some of these methods include staying hydrated, consuming hot beverages and using a humidifier, according to WebMD.
Staying hydrated helps the mucus membranes stay moist, which is especially important during the winter months when the air is dry. There is some clinical evidence available that suggests drinking hot tea with honey soothes irritated throats, reports WebMD. Humidifiers moisturize the air, which also helps reduce dry cough symptoms. However, it is important to clean humidifiers regularly. Otherwise, they start to emit fungus, mold and bacteria into the air.
Common causes of a chronic dry cough include smoking, environmental irritants, allergies, post nasal drip and asthma, notes WebMD. Certain chronic lung diseases are also associated with a chronic dry cough. Gastric reflux is another cause, and additional symptoms, such as heartburn, increased saliva and a burning throat, accompany this condition.
Whooping cough, influenza, viral illnesses and swallowing or inhaling a foreign object are more rare causes of dry cough, explains WebMD. Certain medications for heart and blood pressure issues are also associated with a chronic dry cough.
If a cough persists for more than two weeks, it may be an indication of a more serious problem requiring medical evaluation, according to Healthline. Additional symptoms that indicate the need for a medical evaluation include fever, chest pain, drowsiness and confusion.
