Coughing is a natural defense mechanism of the body. It’s goal is to expel secretions or a foreign body from the lungs through the airways. There are different variations: it can be acute or chronic, dry or wet. It most often appears because of a viral infection, but can be caused by other diseases, such as gastro-esophageal reflux, asthma or allergies.
Coughs can be grouped into two types:
- Dry coughs, without any fluid. The tend to scratch the throat and can be painful;
- Wet coughs, with fluid. Also called a productive cough (because it produces mucus or phlegm), it feels as if something is rattling in the chest.
Both types of coughs can be exhausting, especially when fits occur. They can cause severe throat irritation, headaches and even insomnia.
