Have you ever experienced a persistent cough that seems to only bother you at night? It can be frustrating and disruptive to your sleep, leaving you tired and irritable the next day.
While there are common causes for a cough, such as a cold or allergies, sometimes the reason for your nocturnal cough can be rather strange. Let’s explore some of these unusual causes and how you can find relief.
1. Acid reflux
You might not associate acid reflux with a cough, but it can actually be the culprit behind your nocturnal coughing episodes. When stomach acid flows back into the esophagus, it can irritate the lining and trigger a cough reflex.
This is especially noticeable at night when lying down, as gravity isn’t helping keep the acid in your stomach.
2. Asthma
Asthma is a chronic condition that causes inflammation and narrowing of the airways, leading to breathing difficulties. Although asthma symptoms can occur at any time, some people experience nocturnal coughing as a primary symptom.
When the lungs are more relaxed during sleep, the airways can constrict, resulting in coughing fits.
3. Postnasal drip
Postnasal drip occurs when excess mucus drips down the back of your throat from your nose. This can cause irritation and lead to a cough.
While postnasal drip can happen during the day, it often worsens at night when lying down due to the mucus pooling in your throat.
4. Sleep apnea
Obstructive sleep apnea is a sleep disorder characterized by repeated pauses in breathing during sleep. These pauses can cause you to wake up briefly, leading to a coughing fit or throat clearing.
The coughing is your body’s response to reopen the airway and resume breathing.
5. Medications
Believe it or not, certain medications can cause a nocturnal cough as a side effect. ACE inhibitors, commonly prescribed for high blood pressure, have been known to cause coughing in some individuals.
If you suspect your medication is causing your cough, consult with your healthcare provider to explore alternative options.

6. Gastroesophageal reflux disease (GERD)
GERD is a chronic condition where stomach acid consistently flows back into the esophagus, causing irritation. While acid reflux was mentioned earlier, GERD refers to more severe and persistent cases.
The constant exposure to stomach acid can trigger a nocturnal cough, particularly when lying down.
7. Allergic rhinitis
If you have allergies, you’re probably familiar with the itchy, runny nose and sneezing. However, allergies can also cause a nocturnal cough due to nasal congestion and postnasal drip.
When exposed to allergens, such as pollen or pet dander, your body releases histamines that can irritate your airways and lead to coughing.
8. Lung infections
Infections like bronchitis or pneumonia can cause coughing, both during the day and at night. However, in some cases, the cough may worsen when lying down due to the accumulation of mucus in the airways.
If you suspect you have a lung infection, it’s essential to seek medical attention and receive appropriate treatment.
9. Environmental triggers
Your immediate environment can play a role in your nocturnal coughing episodes.
Common irritants like dust mites, mold, or pet dander can cause allergies and trigger coughing, especially at night when you’re exposed to them for an extended period while sleeping.
10. Chronic bronchitis
Chronic bronchitis is a long-term inflammation of the bronchial tubes, typically caused by smoking or prolonged exposure to irritants.
The hallmark symptom of chronic bronchitis is a persistent cough that lasts for at least three months, and it often becomes worse at night.
In conclusion, a nocturnal cough can have various strange causes, ranging from acid reflux and asthma to medications and environmental triggers.
If you’re experiencing a persistent and bothersome nocturnal cough, it’s important to consult with a healthcare professional to determine the underlying cause and receive appropriate treatment.
