Coughing at night: Ever notice a cough that’s manageable by day but flares the moment you lie down? You’re not imagining it; nighttime coughing is real and usually driven by a mix of factors.
Why does your cough get worse at night?
During the day, sitting or standing helps mucus drain naturally. At night, lying down lets mucus pool in the throat or chest, which triggers the cough reflex. An upright position makes breathing easier, while lying flat causes a buildup and cough.

After a cold or sinus infection, post-nasal drip can make mucus slide down the back of your throat. Lying flat at night lets that mucus flow backwards, irritating the throat and triggering coughs.
If you have asthma or chronic bronchitis, coughing can also get worse at night. Airways are more sensitive, and cool nighttime air can set off coughing or wheezing while you sleep.
How to soothe your cough at night?
- You can use an extra pillow or even raise the head of your bed. Sleeping on an incline helps you drain mucus and prevent acid reflux. This small change can make a big difference.
- You can use a humidifier to add moisture to the air. This can soothe your dry throat and also loosen mucus. Make sure you clean the humidifier regularly to avoid mould or bacteria.
- A spoonful of honey can coat your throat and also calm a dry cough. Take one to two tablespoons 30 minutes before bed, and you can also mix it with warm water or hot tea.
- If acid reflux might be the cause, don’t eat at least two to three hours before sleeping. Avoid spicy, acidic or fried foods in the evenings. You can also try sleeping on your left side, which can reduce reflux.
- Depending on the cause of your cough, over-the-counter medicines might help. You need to always read the labels and talk to a pharmacist or a doctor if you are unsure about the medication and the dosage.

When should you see a doctor?
Not every cough is harmless. See a doctor if it lasts more than 2–3 weeks, or if you have a fever, chest pain, or trouble breathing. If coughing is interfering with your sleep or daily activities, consider having it evaluated. Persistent coughs can sometimes signal something more serious, like pneumonia.
