Quick Answer
A cough that gets worse at night can be caused by asthma, allergies, acid reflux, post-nasal drip, respiratory infections, or chronic lung conditions. Lying down can sometimes make these problems more noticeable. If your night-time cough keeps happening or affects your sleep, it is important to find the underlying cause.
Why Does Coughing Get Worse at Night?
When you lie down, mucus can collect in the throat, stomach acid can move upward more easily, and airway inflammation may become more noticeable. This can trigger coughing during the night.
Common Causes
Asthma: Night-time coughing can be an important symptom of asthma, even without obvious wheezing.
Acid Reflux: Stomach acid reaching the throat can irritate the airways and cause a dry cough.
Allergies: Dust mites, bedding, pets, and other allergens can trigger coughing while sleeping.
Post-Nasal Drip: Mucus draining from the nose into the throat can cause repeated coughing.
Respiratory Infections: A cough may continue for weeks after a cold, flu, bronchitis, or other infection.
COPD: People with chronic lung disease may experience increased coughing and mucus production.
When Should You See a Doctor?
Consult a pulmonologist if your night cough:
- Lasts for more than 3 weeks
- Frequently disturbs your sleep
- Is accompanied by wheezing
- Causes shortness of breath
- Produces blood
- Occurs with unexplained weight loss or fever
