What is the Difference Between Dry Cough and Wet Cough?

🆚 Go to Comparative Table 🆚

The main difference between a dry cough and a wet cough lies in the presence of mucus or phlegm. Here are the characteristics of each type of cough:

  • Dry Cough: Also known as a hacking cough, it has a consistent tone and is free from the sound of mucus. It is caused by irritation and inflammation of the airway. A cough accompanied by a tickling sensation in the throat is usually a dry cough, and you can also feel chest tightness after a dry cough.
  • Wet Cough: Also known as a productive or chest cough, it raises phlegm (or liquid) from the lower respiratory tract. Wet coughs are usually temporary and associated with viruses like colds and influenza, and accompanied by symptoms like a stuffy nose, aches/pains, sore throat, and wheezing.

Understanding the difference between a dry cough and a wet cough can help you identify the type of cough you or your child is experiencing and determine if further medical attention is necessary. If a cough persists or is accompanied by other symptoms of illness, it is advisable to consult a healthcare professional.
