Question

Why does my child always cough at night?

Answer

There could be various reasons why your child coughs at night. Here are some common possibilities:

1. Allergies: Your child might be allergic to something in their bedroom environment, such as dust mites, pet dander, or pollen. Allergies can trigger coughing, especially at night when your child is lying down and mucus can drip down the throat.

2. Postnasal drip: Postnasal drip occurs when excess mucus drips down the back of the throat. This can be caused by allergies, a cold, sinus infection, or other respiratory issues. Postnasal drip often worsens at night, leading to coughing.

3. Asthma: Asthma can cause nighttime coughing, particularly if your child’s asthma is triggered by allergens, exercise, or cold air. Coughing may be the only symptom of asthma, especially at night. If your child is coughing more than two nights/week in their sleep, we recommend follow up with your primary care provider.

4. Reflux: Gastroesophageal reflux disease (GERD) or acid reflux can cause stomach acid to back up into the esophagus, leading to irritation and coughing, particularly when lying down.

5. Respiratory infections: Respiratory infections such as colds, flu, bronchitis, or pneumonia can cause coughing, especially at night when congestion and irritation worsen due to lying down.

6. Environmental factors: Dry air in the bedroom, especially during the winter months when heating systems are running, can lead to coughing. Using a humidifier in the bedroom may help alleviate coughing caused by dry air.

7. Other triggers: Other factors such as irritants in the air (e.g., cigarette smoke, strong odors), poorly controlled indoor air quality, or certain medications could also contribute to nighttime coughing.

If your child’s nighttime coughing persists or is accompanied by other concerning symptoms such as difficulty breathing, fever, chest pain, or wheezing, it’s essential to consult with a healthcare professional for proper evaluation and treatment. They can help determine the underlying cause of the cough and recommend appropriate management strategies.
