Dry cough

A dry cough is a type of cough that occurs without phlegm production, often accompanied by a tickling sensation in the throat. Many different factors can lead to a dry cough.

What Are the Common Causes of a Dry Cough?

  • The early stage of a viral infection
  • Seasonal allergies
  • Dry air or irritants such as dust and smoke
  • Mucus draining down the back of the throat (postnasal drip)

What Can Help in Daily Life?

Drinking plenty of water, keeping indoor air humid, and staying away from irritant sources are general steps that can help support throat comfort during a dry cough. Understanding the difference between a dry and a wet cough can also help in figuring out the right approach.

When Should You Consult a Healthcare Professional?

If a dry cough lasts longer than three weeks, becomes severe enough to disrupt sleep, or is accompanied by additional symptoms such as shortness of breath, consulting a healthcare professional is recommended.
