A cough that gets worse at night or when lying down is often caused by mucus draining down the back of the throat, acid reflux, asthma or irritation in the airways.
When you lie flat, mucus and stomach acid can move more easily towards the throat, while changes in your breathing patterns during sleep can make some coughs feel worse.
Although many nighttime coughs are not serious, a persistent cough should be checked by a healthcare professional, especially if it affects your sleep or daily life.

What are common causes of a cough that gets worse at night?
There are several reasons why a cough may become more noticeable when you are trying to sleep. One common cause is post-nasal drip, where mucus from the nose or sinuses runs down the back of the throat. This can irritate the throat and trigger coughing, particularly when lying flat.
Acid reflux is another common cause. This happens when stomach acid travels back up towards the throat, causing irritation and a cough. Some people may not experience heartburn but may still have a reflux-related cough, known as silent reflux.
Asthma can also cause coughing that is worse at night. Nighttime coughing, wheezing or chest tightness can happen because airways can become more sensitive during sleep.
Why does lying down make my cough worse?
When you lie down, gravity no longer helps clear mucus from your airways as effectively. This can allow mucus to collect at the back of the throat, causing irritation and coughing.
Lying flat can also make acid reflux more likely because stomach contents can move upwards more easily. This is why some people notice coughing after going to bed or during the night.
Changes in the body during sleep can also affect breathing. The airways naturally become slightly narrower during sleep, which may make symptoms worse for people with conditions such as asthma or chronic bronchitis.
What symptoms can happen with a nighttime cough?
The symptoms that come with a nighttime cough can provide clues about the cause. Some people may have a dry, tickly cough, while others may cough up mucus.
Other symptoms can include a blocked or runny nose, throat irritation, wheezing, chest tightness, a sour taste in the mouth or a hoarse voice. A cough caused by reflux may be worse after eating, especially after large meals or when lying down soon afterwards.
A cough is considered persistent if it lasts for more than eight weeks in adults. A cough lasting more than three weeks is known as a chronic or ongoing cough and may need medical advice, particularly if it is unexplained.
What are common treatments for a nighttime cough?
- Inhalers
- Nasal sprays
- Allergy medicines
- Reflux treatment
- Lifestyle changes
- Hydration
- Cough medicines
- Trigger avoidance
Treatment depends on what is causing the cough. If allergies, sinus problems or post-nasal drip are responsible, treatment may include nasal sprays, allergy medicines or advice on managing triggers.
For acid reflux-related coughing, lifestyle changes can help. These may include avoiding large meals close to bedtime, reducing foods that trigger symptoms and raising the head of the bed slightly.
If asthma is the cause, a GP or specialist may recommend inhalers to help control inflammation and open the airways. It is important to use any prescribed treatment as advised.
What are common remedies for a cough that gets worse at night?
There are several simple steps that may help reduce nighttime coughing. Drinking enough fluids can help keep mucus thinner and easier to clear. Keeping the bedroom air comfortable and avoiding smoke or strong smells may also reduce irritation.

Sleeping with your head slightly raised can help some people, particularly if reflux or mucus drainage is contributing to symptoms. A warm drink before bed may soothe an irritated throat.
Cough medicines are not suitable for everyone, and some coughs need treatment of the underlying cause rather than simply reducing the cough itself.
When should I see a doctor about a nighttime cough?
Many coughs improve within a few weeks, particularly after a cold or viral infection. However, you should seek medical advice if your cough lasts longer than three weeks, keeps returning or is affecting your sleep.
You should seek urgent medical help if your cough is accompanied by coughing up blood, chest pain, difficulty breathing, unexplained weight loss or a high fever.
Research suggests that coughing is very common, with studies estimating that around 10% of adults experience a chronic cough at some point. A persistent cough can have a significant effect on sleep quality and quality of life, so identifying the cause is important.
