How do I stop coughing at night? It is the question that arrives at 2am, when a cough that barely bothered you all day suddenly will not let you sleep. The short answer is that you cannot switch a cough off, but you can make the night easier: sleep with your head and shoulders raised, have a hot lemon and honey drink before bed, keep the bedroom air moist, and treat the cause behind the cough rather than the cough alone. Most coughs clear up on their own within three to four weeks, according to the NHS, and a night cough after a cold is usually the tail end of an infection, not a new illness.
This guide explains why coughing gets worse once you lie down, what actually helps tonight, what the research says about honey, and when a night cough is a reason to call your GP.
Why is a cough worse at night?
A cough is a reflex. It clears mucus, dust and germs from your airways, and it is meant to fire when something irritates them. At night, four things change at once, and each one can make that reflex fire more often.
First, lying flat changes where mucus goes. During the day, gravity helps mucus from your nose and sinuses drain forwards and you swallow it without noticing. Lying flat removes that slope, so mucus pools at the back of the throat instead. Doctors call this postnasal drip, and it is the most common reason a cold cough starts the moment your head hits the pillow. The throat lining answers the pooling mucus with a cough, and the cough keeps you awake, which makes the irritation worse.
Second, stomach acid finds it easier to rise when you lie down. The valve at the bottom of the food pipe relies partly on gravity to stay closed, so a late or heavy meal can let small amounts of acid reach the throat during the night, often without any heartburn at all. The NHS lists a cough that keeps coming back among the symptoms of acid reflux, and notes that reflux symptoms are often worse after eating, when lying down and when bending over.
Third, asthma follows a daily rhythm. The NHS notes that symptoms are more likely to be asthma if they keep coming back, are worse at night and early in the morning, or follow triggers such as exercise, cold air or allergens. For some people, a dry cough that only appears at night is the only sign of asthma, with no wheeze at all. If a cough keeps waking you in the second half of the night, or comes with wheezing, chest tightness or breathlessness, asthma is worth discussing with your GP.
Fourth, the bedroom itself can irritate airways that coped fine all day. Heated air in winter is dry, and dry air dries the throat. Dust mites live in mattresses and pillows, and their droppings are a common trigger for sensitive airways. Smoke, vaping and strong scents in the bedroom add to the irritation. None of these causes a cough on its own, but together, in a quiet dark room with nothing to distract you, they are enough to keep you coughing.
There is also a simpler reason a night cough feels worse than a day cough: at night there is nothing else to think about. A mild cough that you barely notice while working or talking becomes the only sound in the room at 3am. That does not make it imaginary. It does make it harder to sleep through, which is why the steps below aim at sleep as much as at the cough.
How do I stop coughing at night?
There is no single trick that stops a night cough, and anyone promising one is selling something. What works is a small set of steps that tackle the four causes above, done together, before bed.
1. Raise your head and shoulders
Sleep with your head and shoulders raised on extra pillows, or a wedge pillow if you have one. Raising the upper body keeps mucus draining forwards instead of pooling at the back of the throat, and it makes it harder for stomach acid to rise. It is the single most useful change for a cough that starts as soon as you lie down. If the cough is mainly a postnasal drip cough, this step alone often cuts the worst of it.
2. Have a hot lemon and honey drink before bed
The NHS suggests hot lemon and honey to soothe a cough. Squeeze half a lemon into a mug of boiled water and add one to two teaspoons of honey. The NHS is clear that there is limited evidence these remedies treat a cough, but that hot lemon with honey has a similar soothing effect to some cough medicines. The warmth and the honey coat the throat, which calms the tickle that triggers the cough reflex. Have it shortly before bed rather than hours earlier, so the soothing effect covers the first part of the night. Do not give honey to a baby under one year old, and do not give hot drinks to small children.
3. Drink enough during the day
A dry throat coughs more easily. Keep drinking water through the day, and keep a glass of water by the bed so a sip is within reach when a coughing fit starts. Fluids also keep mucus thinner, which helps it drain instead of sitting in the throat. This sounds too simple to matter, and it is the step most people skip.
4. Keep the bedroom air moist, but not damp
If the heating has been on all evening, the air in the bedroom is probably dry. A cool mist humidifier can help, provided you clean it regularly so it does not grow mould. If you do not have a humidifier, a bowl of water near a radiator, or a damp towel hung where it can dry slowly, adds some moisture to the air. Do not overdo it. A room that is damp encourages mould and dust mites, which irritate airways just as much as dry air does.
5. Sort out the bedroom
Wash bedding regularly, and use dust mite proof covers on the mattress and pillows if coughing at night is a regular problem. Keep the bedroom free of smoke and vaping, and avoid strong air fresheners or scented candles at night. If a pet sleeps on the bed and the cough is worse on the nights it does, try keeping the pet out of the bedroom for a week and see whether the cough eases.
6. Do not eat a heavy meal late
If your night cough follows late dinners, or comes with a sour taste, throat clearing or morning hoarseness, reflux may be part of the problem. Eat your last meal at least three hours before bed, keep it light, and avoid foods that trigger your reflux, such as spicy food, citrus, chocolate and alcohol. Sleeping on your left side can also help, because it keeps the stomach below the food pipe.
7. Treat the cold, not just the cough
Most night coughs follow a cold, and the cough is the last symptom to go. The NHS advises rest, fluids, and paracetamol or ibuprofen if you have a fever or aches, and our guide to treating a cold at home covers the full routine. A saline nasal spray before bed can help if a blocked nose is forcing you to breathe through your mouth, which dries the throat and makes coughing worse.
What about cough medicines?
Over the counter cough medicines are the first thing many people reach for, and the evidence for them is thin. The NHS notes there is limited evidence that cough remedies work, and that hot lemon with honey has a similar soothing effect to some cough medicines. Cough medicines do not treat the cause, and they do not shorten the illness.
That does not make them useless. A cough syrup can soothe a sore throat for an hour or two, and for some people that is enough to fall asleep. But if you are choosing between a cough medicine and a honey and lemon drink, the drink is cheaper, has fewer side effects, and works about as well. Pharmacists can advise on which product, if any, suits your type of cough, and whether it is safe alongside other medicines you take. Never give an adult cough medicine to a child unless the label says it is suitable for their age, and never combine products that contain the same active ingredient.
Antibiotics do not help a viral cough. Most coughs are caused by a cold, flu or another respiratory infection, and the NHS says there is usually no need to see a GP if you have a short term cough and are otherwise well. Asking for antibiotics will not speed recovery, and it adds to the wider problem of antibiotic resistance.
Does honey really help? What the research says
Honey is the home remedy with the best evidence behind it, and the evidence is still modest. A Cochrane review by Oduwole and colleagues, published in 2018, pooled six randomised trials involving 899 children aged 12 months to 18 years. It found that honey probably reduces cough frequency more than no treatment or a placebo, and is probably more effective at providing cough relief and reducing the impact of cough on children’s sleep at night than no treatment. The review rated the evidence as low to moderate certainty, and noted that most of the children received honey for just one night, which limits what can be claimed.
Honey performed about as well as dextromethorphan, a common cough medicine ingredient, in reducing cough frequency. It probably works better than diphenhydramine, another cough medicine ingredient. The review found no strong evidence for or against honey overall, and it stressed that honey must never be given to infants under 12 months because of the risk of infant botulism.
For adults, the evidence is thinner, but the mechanism is the same: honey coats the throat and calms the cough reflex for a while. That is why the NHS includes hot lemon and honey among its self care suggestions for a cough. It is a soothing measure, not a cure, and it works best as part of the routine above rather than on its own.
How do I stop my child coughing at night?
A child coughing at night is miserable for the whole household, and the rules are slightly different from the adult ones. Children over one year old can have honey before bed, and the Cochrane review found honey probably reduces the impact of cough on children’s sleep at night. A teaspoon of honey, on its own or stirred into warm water, half an hour before bed is the usual approach. Never give honey to a baby under one, and never give a hot drink to a small child.
Raise the head of your child’s bed slightly, or use an extra pillow for an older child, so mucus drains forwards rather than pooling. Keep the bedroom air moist and free of smoke. Offer fluids during the day, and keep water by the bed. A saline nasal spray before bed can help a child who is breathing through their mouth because their nose is blocked.
Our guide to paracetamol or ibuprofen for a child with a fever covers which medicine to use and when, if your child also has a temperature. Do not give a child paracetamol and ibuprofen at the same time, and never give aspirin to a child.
Call NHS 111, or your GP, if your child has a cough that lasts more than three weeks, is struggling to breathe, is wheezing, has a temperature that does not come down, or is not drinking. If your child is struggling to breathe, or their lips look blue, call 999.
When should I see a GP about a night cough?
Most night coughs are the tail end of a cold and need no medical attention. The NHS says a cough will usually clear up on its own within three to four weeks. See a GP if you have had a cough for more than three weeks, if you are losing weight for no reason, or if you have a weakened immune system, for example because of chemotherapy or diabetes.
Ask for an urgent GP appointment, or get help from NHS 111, if the cough is very bad or quickly gets worse, for example you have a hacking cough or cannot stop coughing, or if you are coughing up blood. Call 999 if you are struggling to breathe, have chest pain, or your lips look blue.
There are also patterns that deserve a GP visit even before the three week mark. A cough that keeps coming back, is worse at night and early in the morning, or follows triggers such as exercise or cold air may point to asthma, and asthma is much easier to live with once it is treated. A cough that started after you began a new blood pressure medicine, particularly one ending in “pril”, is a known side effect and your GP can usually switch you to a different medicine. A cough that follows every meal, or comes with regular heartburn, may be reflux, which is also treatable.
If you are unsure whether your cough is a cold or flu, our guide on how to tell a cold from flu explains the three differences the NHS uses. And if the cough is still going after three weeks, do not just wait longer. The three week threshold is the point at which the NHS says a cough stops being a normal cold symptom and starts being something worth checking.
Frequently asked questions
How do I stop coughing at night?
How do I stop coughing at night? Sleep with your head and shoulders raised on extra pillows, have a hot lemon and honey drink before bed, keep a glass of water by the bed, and keep the bedroom air moist. If the cough follows a cold, it should clear within three to four weeks. See a GP if it lasts longer than three weeks, or if you are coughing up blood, losing weight, or struggling to breathe.
Why is my cough worse at night than during the day?
Lying flat lets mucus pool at the back of your throat instead of draining forwards, which triggers the cough reflex. Stomach acid also rises more easily when you lie down, and asthma symptoms are often worse at night and early in the morning. Dry heated air and dust mites in bedding add to the irritation, and the quiet of the night makes every cough feel louder.
Does honey help a cough at night?
Honey probably helps a little. A Cochrane review of six trials in 899 children found honey probably reduces cough frequency more than no treatment or a placebo, and probably reduces the impact of cough on children’s sleep at night. The evidence is low to moderate certainty. The NHS suggests hot lemon and honey as a soothing measure, and notes there is limited evidence it treats a cough. Never give honey to a baby under one year old.
How long should a cough last?
A cough will usually clear up on its own within three to four weeks, according to the NHS. If it lasts longer than three weeks, or you have other symptoms such as weight loss or a weakened immune system, see your GP. A cough that lasts more than eight weeks is classed as chronic and always deserves medical attention.
Should I take cough medicine for a night cough?
You can, but the evidence is thin. The NHS notes there is limited evidence that cough medicines work, and that hot lemon and honey has a similar soothing effect to some cough medicines. A cough medicine may help you fall asleep by soothing a sore throat, but it will not treat the cause or shorten the illness. A pharmacist can advise on which product, if any, suits your cough.
When should I call 111 about a cough?
Call NHS 111 if your cough is very bad or quickly gets worse, you cannot stop coughing, you are coughing up blood, or you are worried about a child who is struggling to breathe or not drinking. Call 999 if someone is struggling to breathe, has chest pain, or their lips look blue.
