Wet cough

A wet cough is a reflex that helps clear mucus that has built up in the airways. It commonly appears in the later stages of an infection.

What Are the Common Causes of a Wet Cough?

  • The later stage of viral infections such as the common cold
  • Mucus draining from the sinuses toward the throat (postnasal drip)
  • Seasonal infections affecting the respiratory tract

What Can Help in Daily Life?

Drinking plenty of water can help the body clear mucus more easily. With this type of cough, it's generally advised not to suppress the body's effort to clear mucus; keeping indoor air humid can also be soothing.

When Should You Consult a Healthcare Professional?

If the phlegm's color changes noticeably, the cough lasts longer than three weeks, or additional symptoms such as high fever or shortness of breath are present, consulting a healthcare professional is recommended.
