Why Do Coughs Get Worse at Night?

Many people notice their cough gets worse as soon as they lie down. Gravity plays a big part.

When you lie flat, mucus from your nose and sinuses can drip down the back of your throat. Doctors call this postnasal drip, and it tickles the throat and sets off coughing.

Dry indoor air in winter can also irritate your airways. Heating systems pull moisture from the air, which leaves your throat scratchy.

Common Causes of a Nighttime Cough

Cleveland Clinic lists several causes of coughing at night. Some are short-term, and others need a doctor to manage.

Cause	What it feels like
Cold, flu or other infection	Cough with a runny nose, sore throat or fever
Postnasal drip	Tickle or drip at the back of the throat
Allergies	Itchy eyes, sneezing and a dry cough
Asthma	Wheezing, chest tightness and coughing at night
Acid reflux	Cough with heartburn or a sour taste, worse after meals
Some medicines	A dry, lasting cough, linked to some blood pressure drugs
Smoking	A long-term cough, often worse in the morning

Change Your Sleep Position

How you lie in bed can make a big difference. Cleveland Clinic family physician Elizabeth Rainbolt, MD, suggests raising your head so drainage does not pool in your throat.

Add an extra pillow or use a wedge pillow.
Raise the head of the bed a few inches with sturdy risers.
Try sleeping on your side, which can ease a dry cough.
Avoid lying flat on your back, which can worsen postnasal drip.

Do not prop your head too high. A sharp angle can strain your neck and disturb your sleep.

Fix the Air in Your Bedroom

Moist air soothes irritated airways. Cleveland Clinic recommends a cool-mist humidifier at night and bedroom humidity of about 40% to 50%.

Run a cool-mist humidifier while you sleep.
Clean it often to stop mold and bacteria from growing.
Take a hot shower before bed to breathe in steam.
Use an air purifier if dust or pollen bothers you.
Wash bedding in hot water to cut down on dust mites.

Too much humidity can feed mold, so keep an eye on the level. Learn the right way to set one up in our guide on how to use a humidifier safely.

What helps your nighttime cough the most?

Honey and warm drinks
A humidifier
Cough drops

Warm Drinks and Honey

Warm liquids can loosen mucus and soothe a sore throat. Herbal tea or warm water with honey are good choices.

The NHS suggests 1 to 2 teaspoons of honey in a mug of hot water with half a lemon. It adds that the evidence is limited, but many people find it comforting.

Sip a warm drink an hour or so before bed.
Keep a glass of water on your nightstand.
Stay well hydrated during the day to keep mucus thin.
Skip alcohol, which can dry you out and disturb sleep.

Important. Honey is not safe for babies under 1 year old. The NHS also advises against giving hot drinks to small children.

Rinse and Soothe Your Throat

A few simple habits can calm an irritated throat before bed.

Gargle with about a teaspoon of salt in a glass of warm water.
Use a saline nasal spray to clear mucus from your nose.
Suck on a lozenge or cough drop, but not while lying down.
Try menthol drops, which may help open your sinuses.

Never let young children have cough drops, since they can be a choking hazard. Keep them out of reach.

Some foods can change how medicines work. Learn about grapefruit and medicine interactions.

Over-the-Counter Options

A pharmacist can help you choose the right product. The best choice depends on whether your cough is wet or dry.

Type of cough	What may help	Notes
Wet cough with mucus	An expectorant such as guaifenesin, taken during the day	Helps thin mucus so you can clear it
Dry, tickly cough	A cough suppressant or lozenges	May help you cough less at night
Cough from allergies	An antihistamine or decongestant	Ask a doctor first if you have high blood pressure

The NHS says cough medicines will not cure a cough, but they may help you cough less. Some are not suitable for children under 12, so always read the label.

Ask your pharmacist before mixing medicines. Many cold products share the same ingredients, which makes it easy to take too much.

Can Food and Drink Make It Worse?

What you eat and drink in the evening may affect your cough. Acid reflux is a common hidden cause, since stomach acid can rise into the throat when you lie down.

Large, late meals, spicy or fatty foods, chocolate, caffeine and alcohol can all worsen reflux for some people. Notice which foods seem to set off your cough.

Keeping a simple diary for a week can help you spot patterns. Share it with your doctor if the cough continues.

Avoid Common Triggers

Small changes in your evening routine can help you cough less.

Finish dinner a few hours before bed if reflux is a problem.
Avoid smoking and secondhand smoke.
Keep pets out of the bedroom if you are allergic.
Skip strong scents, like candles and air fresheners, near bedtime.
Shower before bed to wash off pollen.

A calm, cool bedroom also supports better rest. Read more tips in our guide on how to sleep better in winter.

Nighttime Coughs in Children

Children often cough more at night when they have a cold. Most coughs in kids clear up on their own.

Raise the head of an older child’s bed slightly, not with pillows for babies.
Run a cool-mist humidifier in the room.
Offer plenty of fluids during the day.
Use saline drops for a stuffy nose.

The Food and Drug Administration advises against over-the-counter cough and cold medicines for children under 2. Talk to a pediatrician or pharmacist before giving any medicine to a child.

Get urgent care if your child struggles to breathe, makes a whooping sound or looks very unwell. Our guide to RSV symptoms in adults and kids lists more warning signs.

Most coughs come from viruses, so antibiotics will not help. Learn more in do antibiotics cure colds or flu.

When to See a Doctor

The NHS calls a cough that lasts more than three weeks a persistent cough. See a doctor if that happens to you.

Cleveland Clinic suggests seeing a doctor sooner if any of these signs appear.

Trouble breathing or shortness of breath
Chest pain
A fever over 101.5 degrees Fahrenheit
Coughing up blood or pink mucus
Swollen ankles
Weight loss for no clear reason

Call emergency services right away if someone has severe trouble breathing. A sinus problem may also cause a lasting cough, so read sinus infection vs. cold to learn the signs.
