To stop coughing at night, first understand why it starts when you lie down. In most people it’s post nasal drip: during the day mucus runs down and out of your nose, but lying down it runs the other way, back into your throat, and you cough. That mucus usually comes from an inflamed, swollen lining inside the nose (rhinitis), so that inflammation is what you need to calm. Tonight, rinse your nose, raise your head, take a spoonful of honey and run a humidifier or diffuser. For the long term, find the origin of the inflammation: an allergy to cats, dogs, dust or food, seasonal allergies, or a high stress load. Then treat that, and support your system with a healthy lifestyle and a carb, sugar and alcohol detox.

There is nothing more exhausting than a cough that leaves you alone all day and then starts the moment your head touches the pillow. You lie down, you relax, and there it is: a tickle at the back of the throat, a cough, another one, and suddenly it’s 3 a.m. and nobody in the house is sleeping.

The interesting thing is that your body is actually built to cough less at night. When researchers recorded coughs over 24 hours, the fewest happened between 2 and 5 a.m., less than 3% of the day’s total, in people with asthma and with chronic cough alike (Hsu et al., European Respiratory Journal, 1994). So if you cough your way through the night, something is triggering that cough over and over. Find that trigger, and you’ve found your remedy. This guide is part of our cough series; for every type of cough, start with how to stop coughing.

The short version

  • Night coughing is very often post nasal drip: mucus running back down your throat when you lie down.
  • Behind that mucus is usually rhinitis, an inflamed and swollen lining inside the nose. Calm that inflammation.
  • Check the origin: pets (cats, dogs), dust mites, food, seasonal allergies and your current stress load.
  • Tonight: rinse your nose, sleep with your head raised or on your side, honey before bed, humidifier or eucalyptus diffuser.
  • Long term: a healthy lifestyle and a carb, sugar and alcohol detox help your whole system calm down.
  • A night cough that lasts more than three weeks, or comes with wheezing, fever or breathlessness, needs a proper diagnosis.

Why Do I Cough at Night?

A cough that only shows up when you lie down almost always has a mechanical reason. Gravity changes, the air in your bedroom changes, and your throat suddenly has to deal with things it didn’t have to deal with during the day. The most common reasons:

  • Post nasal drip. Mucus from your nose and sinuses runs down the back of your throat instead of out. By far the most common cause, and the focus of this guide.
  • Rhinitis and allergies. The lining of your nose is inflamed and makes more mucus, often because of something in the bedroom: dust mites in the pillow, pet hair, pollen on your hair and clothes.
  • Acid reflux. Lying flat lets stomach acid creep up and irritate the throat. A sour taste, heartburn or a cough after a late meal points this way. See our guide to GERD cough remedies.
  • Mucus in the chest. When you have a chesty cold or bronchitis, phlegm settles while you lie still and your body coughs to clear it. A Lancet study found that people who produce sputum keep coughing during sleep, while those without sputum barely cough at night at all (Zheng et al., The Lancet, 1997). That cough is doing a useful job.
  • Dry air. Heating dries out the bedroom air and your throat with it, which gives you a tickly, dry cough.
  • Asthma. A night cough with wheezing, a tight chest or breathlessness can be asthma and needs to be checked.

Post Nasal Drip: Mucus Going the Wrong Way

Coughing at night can get a lot worse because of post nasal drip. Put simply, it’s your mucus falling back into your throat.

During the day, while you’re standing and sitting, the mucus your nose produces usually rolls down your nose and out. You blow your nose, you sniff, and most of it never bothers you. When you lie down, it goes the other way. The mucus runs from the back of your nose straight down into your throat, it lands on the very sensitive area around your voice box, and your body does exactly what it’s designed to do: it coughs to protect your airways.

That’s why a post nasal drip cough at night feels so typical. There’s a tickle or a feeling of something stuck at the back of the throat, you clear your throat again and again, and you often wake up with a thick, mucusy throat in the morning. Our full guide to post nasal drip goes deeper into this.

Two simple tricks help a lot in the moment, and you can do them lying in bed: moving moisture from the back of your nose down your throat, and gargling with your mouth closed to shift the mucus without coughing. Both are shown step by step in our guide on how to get excess phlegm out of your throat.

Rhinitis and Night Cough: Calm the Inflammation

Rhinitis simply means inflammation and swelling of the mucous membrane lining inside the nose. It gives you a blocked or runny nose, sneezing and an itchy nose, and that inflamed lining produces far more mucus than usual. More mucus means more post nasal drip, and more post nasal drip means more coughing as soon as you lie down.

The link between the two is strong. A nationwide study of 136,506 children in Japan found that children with rhinitis were around three times more likely to have a dry cough at night, apart from a cold, than children without rhinitis. That link was even stronger in children who did not have asthma, which shows the nose itself, and not only the lungs, can be behind a night cough. The researchers concluded that the upper airways should be examined in every child with a night cough (Higuchi et al., Pediatric Allergy and Immunology, 2012).

So if rhinitis, that inflammation and swelling inside the nose, is the main cause of your night time coughing, then it’s exactly that inflammation we must try and reduce. Cough drops and syrups only quiet the cough for a few hours. Calming the lining of your nose stops the mucus at the source.

Find the Origin of the Inflammation

Only once we understand the origin of that inflammation can you start treating it accordingly. Inflammation in the nose doesn’t appear out of nowhere. These are the things I always check:

1. Allergies: cats, dogs, dust and food

Does the cough get worse when the cat sleeps on the bed, or after a weekend at a friend’s house with a dog? Pet allergies are one of the most common reasons for a nose that’s inflamed all year round. Dust mites, which live in pillows, mattresses and duvets, are another, and they explain why so many people only cough in bed. Food matters too: watch whether certain foods, like dairy, wheat or something you eat every evening, are followed by a stuffy nose and a worse night. Keep a simple diary for two weeks: what you ate, where you slept, whether the pets were in the bedroom, and how you coughed.

2. Seasonal allergies

If your night cough comes back every spring or late summer, pollen is a strong suspect. You carry pollen into the bedroom on your hair, skin and clothes, and you breathe it in all night. Showering and washing your hair before bed, keeping clothes worn outside out of the bedroom, and closing the windows on high pollen evenings can make a real difference.

3. Your current stress load

Stress is often forgotten, but it has a real effect on your immune system and on how inflamed your body is. A demanding period at work, worries at home or simply not sleeping enough can make the lining of your nose more reactive, and a night cough in turn keeps you from the sleep you need to recover. Be honest about how much you’re carrying right now. Slow breathing before bed, a short walk outside every day and a calm bedtime routine are part of the treatment, not a luxury.

4. Other causes to rule out

Reflux, asthma, a chest infection and dry bedroom air can all cause a night cough too. If the checks above don’t point anywhere, an ENT specialist (ear, nose and throat) can examine your nose and sinuses, and an allergist can test which allergies you really have. Knowing the cause saves you months of guessing.

How to Stop Coughing at Night: What to Do Tonight

While you look for the origin, you still want to sleep. This is what I’d do tonight:

  1. Rinse your nose before bed. A saltwater nasal rinse washes out mucus, pollen and dust before you lie down. A Cochrane review found that saline irrigation reduced symptoms in people with allergic rhinitis (Head et al., Cochrane, 2018). Use sterile, boiled and cooled, or distilled water, never straight from the tap.
  2. Take a warm shower or sit in a steamy bathroom. Steam loosens the mucus so it clears before bed instead of dripping all night, and it washes pollen off your hair and skin.
  3. A spoonful of honey right before bed. Honey coats the throat and calms the urge to cough. Research in children shows honey eases a cough better than no treatment (Oduwole et al., Cochrane, 2014). Only for children over 12 months. Read more in honey for cough.
  4. A warm cup of tea in the evening. Ginger, lemon and honey, thyme or chamomile all soothe the throat. Avoid caffeine in the evening. Our tea for cough guide has the recipes.
  5. Raise your head or sleep on your side (see the next section).
  6. Run a cool mist humidifier if your bedroom air is dry. Clean it daily, because a dirty humidifier spreads mould and makes allergies worse.
  7. Keep a glass of water by the bed. When the tickle comes, sip and swallow instead of coughing.
  8. Press the acupressure points. The points on the chest and wrist calm a coughing fit while you lie in bed. See the acupressure points for cough chart.

The Best Sleeping Position to Stop Coughing

The best sleeping position to stop coughing is with your head and shoulders raised, or on your side. Lying flat on your back lets mucus run straight down the back of your throat, and that’s the position that keeps a post nasal drip cough going all night.

  • Raise your upper body, not just your head. Use a wedge pillow or put something under the head of the mattress so your neck doesn’t bend forward. Raising the head end also helps if reflux is part of the problem.
  • Sleep on your side if you can’t get used to sleeping raised. Mucus then drains more to the side instead of straight into the throat.
  • If one side of your nose is blocked, lie on the other side. The blocked side is usually higher and drains more easily.
  • Babies always sleep flat on their back, on a firm mattress with no pillows. Never raise a baby’s head with pillows.

How to Stop Coughing at Night Naturally

These natural remedies work on the cause, the inflamed nose and the mucus, rather than just switching the cough off:

Eucalyptus oil in the bedroom

Eucalyptus in the diffuser is my go-to for a blocked nose and a night cough. It opens the airways, makes breathing through the nose easier and helps mucus flow. The main compound in eucalyptus oil, 1,8-cineole, reduced coughing fits in people with acute bronchitis in a controlled trial (Fischer and Dethlefsen, 2013). Put a few drops in a diffuser an hour before bed. Only ever buy pure, food grade oil.

For children: from age 3, eucalyptus in the diffuser in their bedroom can be a real relief. Between 2 and 3, use a blend made for small children instead, like Plant Therapy Sniffle Stopper KidSafe. Under 2, skip the oils and use a humidifier and saline drops.

Saltwater rinse and steam

The nasal rinse and steam from the list above are the foundation. Done every evening, they keep the lining of your nose clean and calm, and there’s less mucus left to drip down at night.

Wash away the allergens

Wash pillowcases and bedding every week at 60 °C, keep pets out of the bedroom for a few weeks to see if it makes a difference, air the room every morning and vacuum regularly. It sounds simple, but for an allergic nose this is where the change starts.

Propolis and vitamin C

For a night cough that comes with a cold, I take propolis drops and extra vitamin C to support my immune system, the same routine I describe in how I stop coughing. Skip propolis if you’re allergic to bee products.

Soothing herbs

Thyme, marshmallow root, licorice and ivy leaf have been used for generations to calm a cough and soothe the throat. For more remedies you can make at home, see our list of cough remedies at home.

Lifestyle and a Carb, Sugar and Alcohol Detox

Of course a healthy lifestyle is always positive. When your body is constantly inflamed, the nose is often just the place where you notice it. Along with treating the cause, a carb, sugar and alcohol detox can increasingly improve your system’s functions:

  • Cut back on sugar and refined carbs like white bread, pasta, pastries and sweets. Fill your plate with vegetables, good proteins and healthy fats instead.
  • Skip alcohol, especially in the evening. Alcohol makes the lining of the nose swell, dries you out and makes reflux more likely, which is a recipe for a cough at night.
  • Drink enough water during the day so your mucus stays thin and easy to clear.
  • Eat your last meal two to three hours before bed.
  • Move every day and get daylight, which helps both stress and sleep.

Give it at least two to three weeks. Many people notice they breathe more freely through the nose, sleep deeper and cough less once the sugar and alcohol are gone.

Dry Cough at Night

A dry cough at night, with no mucus, often comes from a dried out throat, dry bedroom air, reflux or the tail end of a cold. Post nasal drip can also feel like a dry, tickly cough because the mucus is thin. What helps: a humidifier in the bedroom, water by the bed, honey before bed, no coffee in the afternoon, and humming with your mouth closed instead of coughing. Our guide to dry cough remedies explains both throat tricks and which humidifier to use.

Coughing Up Phlegm at Night

If you cough up phlegm at night, don’t try to suppress it. That cough clears your airways and protects you from mucus settling in your chest. Help it instead: steam before bed, eucalyptus in the diffuser, plenty of warm fluids and sleeping slightly raised. Read how to get rid of phlegm for what the colour of your phlegm tells you, and chest congestion relief if you feel it heavy in your chest.

Child Coughing at Night

Children with a night cough very often have a blocked or runny nose, and the same rule applies: the nose is where to look first. Saline drops or a gentle saline spray before bed, a humidifier, a steamy bathroom, honey (only over 12 months) and the right oils for their age (above) are the safest basics. Keep pets out of the bedroom for a while and wash the soft toys that sleep in their bed. More ideas are in our guide to cough remedies for children.

A child who wakes with violent coughing fits, struggles for breath or makes a “whoop” when breathing in needs to see a doctor. Read about whooping cough in children. A barking cough with a hoarse voice can be croup. Any cough in a baby under 3 months needs a doctor straight away, and a pediatrician should check a night cough in children that keeps coming back.

When to See a Doctor

Natural remedies can settle most night coughs, but they work best once you know what you’re treating. Diagnosis first, then treatment:

  • Get help straight away for trouble breathing, chest pain, blue lips, coughing up blood, or any cough in a baby under 3 months. In an emergency, call 112 (Europe) or 911 (US).
  • Your GP or family doctor for a night cough with a high fever, night sweats, weight loss or a cough that keeps getting worse after a week.
  • An ENT specialist (ear, nose and throat) for a constant blocked nose, post nasal drip, sinus pain or a night cough that lasts more than three weeks.
  • An allergist when you suspect pets, dust mites, food or pollen, or the cough comes back in the same season every year.
  • A pulmonologist (lung specialist) for a night cough with wheezing, a tight chest or breathlessness, which can be asthma.
  • A gastroenterologist when the cough comes with heartburn, a sour taste or is worse after late meals.

Frequently Asked Questions

How do I stop coughing at night?

Rinse your nose with salt water before bed, take a warm shower, have a spoonful of honey, sleep with your head raised or on your side, and run a humidifier or a eucalyptus diffuser. To stop it coming back, find and treat what’s inflaming your nose: allergies, seasonal pollen or stress.

Why do I only cough at night?

Usually because of post nasal drip. During the day mucus runs out of your nose, but when you lie down it runs back into your throat and triggers a cough. Reflux, dust mites in your bedding, dry bedroom air and asthma are other common causes.

What is the best sleeping position to stop coughing?

With your head and upper body raised, or on your side. Lying flat on your back lets mucus run straight down your throat. Babies should always sleep flat on their back without pillows.

How can I stop coughing at night naturally?

A saltwater nasal rinse, steam, honey, ginger or thyme tea, eucalyptus oil in the diffuser, a humidifier and clean bedding. Long term, a healthy lifestyle and a carb, sugar and alcohol detox help calm the inflammation behind the cough.

Can rhinitis cause a cough at night?

Yes. Rhinitis is inflammation and swelling of the lining inside the nose. It makes extra mucus that drips down your throat when you lie down. A study of more than 136,000 children found night cough was about three times more common in children with rhinitis.

How do I stop a post nasal drip cough at night?

Rinse your nose before bed, sleep raised or on your side, run a humidifier and use the throat tricks to clear mucus without coughing. Then find the source of the extra mucus, often an allergy, and treat that.

Can stress make a cough worse at night?

It can. A high stress load affects your immune system and how inflamed your body is, and a night cough steals the sleep you need to recover. A calm bedtime routine and slow breathing are part of the treatment.

When should I worry about coughing at night?

See a doctor if it lasts more than three weeks or comes with wheezing, breathlessness, fever, night sweats, chest pain or blood. Any cough in a baby under 3 months, or a child with a whoop, needs a doctor straight away.
