What Causes a Cough?
Cold and Flu
The most common cause. The cough often lingers after other symptoms are gone.
Allergies and Post-Nasal Drip
Mucus dripping down the back of the throat triggers a tickly cough.
Acid Reflux
Stomach acid rising into the throat can cause a dry cough, often worse at night.
Smoke, Dust and Pollution
Irritants inflame the airways and can cause a long-lasting cough.
Asthma, some blood pressure medicines (ACE inhibitors), chest infections and, less often, tuberculosis (TB) can also cause a cough. Knowing the cause helps you choose the most suitable home remedies for cough.
Dry Cough or Wet Cough?
| Feature | Dry Cough | Wet (Chesty) Cough |
|---|---|---|
| Feels like | Tickly, no phlegm | Chesty, brings up phlegm |
| Common causes | Viral infection, allergies, reflux, asthma | Chest infection, cold with mucus |
| What helps most | Honey, warm drinks, moist air | Fluids, steam from a hot shower, rest |
| Note | Can last weeks after a cold | Coughing up phlegm helps clear the chest, so do not suppress it too strongly |
Do Home Remedies for Cough Really Work?
Home remedies for cough cannot kill a virus, but they can soothe irritation, keep the throat moist and help you sleep. Honey has some of the best evidence for easing night-time cough in people over one year old, and fluids, rest and moist air are low-risk comfort measures. Other remedies, such as ginger tea and turmeric milk, are traditional and comforting, but they have limited scientific proof.
10 Home Remedies for Cough
1. Take Honey
A spoonful of honey, alone or in warm water or tea, coats the throat and can ease a cough, especially at night. Studies in children suggest it may work better than some over-the-counter cough syrups for mild coughs.
Safety tip: Never give honey to babies under 12 months old, because of the risk of infant botulism.
2. Drink Warm Fluids
Warm water, soups, weak tea and warm milk keep the throat moist and thin the mucus. Drink often through the day. See our guide on how much water to drink daily.
3. Add Moisture to the Air
Dry air irritates the airways and worsens a cough. A cool-mist humidifier in the bedroom, or sitting in a steamy bathroom after a hot shower, can help. Clean a humidifier every day.
Safety tip: Do not breathe steam over a bowl of boiling water, as scalds are common, especially in children.
4. Gargle with Warm Salt Water
Mix half a teaspoon of salt in a glass of warm water, gargle for a few seconds and spit it out. It can calm a throat irritated by coughing. It is suitable only for older children and adults who can gargle without swallowing the water.
5. Sip Ginger or Herbal Tea
A warm cup of ginger tea with a little honey is a popular, comforting drink. It is not proven to cure a cough, but the warmth helps. If you take regular medicines, ask a pharmacist before using strong herbal products.
6. Raise Your Head When You Sleep
Lying flat makes post-nasal drip and reflux cough worse at night. An extra pillow can help adults and older children sleep better.
Safety tip: Do not put pillows in a baby’s cot.
7. Suck on Lozenges
Sucking a lozenge increases saliva and soothes a dry, tickly throat. Do not give lozenges or hard sweets to young children because of the choking risk, and check the age limit on the label.
8. Try Turmeric Milk (Haldi Doodh)
A cup of warm milk with a pinch of turmeric is a traditional drink in many homes. It is soothing and safe for most people, but scientific evidence for it is limited, so treat it as comfort rather than treatment.
9. Use a Saline Nasal Spray or Rinse
If your cough comes from mucus dripping down the throat, saltwater nasal sprays or rinses can clear the nose and reduce the drip.
Safety tip: If you make a rinse at home, use distilled water or water that has been boiled and cooled. Never use plain tap water.
10. Avoid Smoke and Other Irritants
Cigarette smoke, incense, strong perfumes, dust and polluted air all prolong a cough. If you smoke, quitting is one of the best things you can do for your lungs. Avoid smoking around children.
What About Cough Syrups and Medicines?
Over-the-counter cough medicines do not work well for most coughs, and they can have side effects. A pharmacist can advise which, if any, suits you. Remember:
- Do not take more than one product with the same ingredient, such as paracetamol.
- Do not give cough and cold medicines to young children, especially under 6, without asking a doctor or pharmacist.
- Do not give aspirin to children or teenagers.
- Antibiotics do not help a cough caused by a virus. Use them only if a doctor prescribes them.
What to Avoid When Using Home Remedies for Cough
- Honey for babies under 12 months
- Leftover or self-prescribed antibiotics
- Smoking, and staying in smoky or dusty rooms
- Very hot drinks and boiling-water steam bowls
- Unproven “miracle” remedies, especially ones sold online
- Ignoring a cough that does not go away
How Long Should a Cough Last?
| Type | Duration | What to Do |
|---|---|---|
| Short-term (acute) cough | Up to about 3 weeks | Home remedies and rest are usually enough |
| Lingering cough | 3 to 8 weeks | See a doctor if it is not improving |
| Long-term (chronic) cough | More than 8 weeks in adults, more than 4 in children | See a doctor for tests |
When to See a Doctor
Get urgent medical help if you or your child has difficulty breathing, noisy or fast breathing, chest pain, coughing up blood, blue lips, a cough after choking on something, or a cough with a very high fever or confusion.
Please also see a doctor if:
- The cough lasts longer than 2 to 3 weeks, especially with fever, night sweats or weight loss, because tuberculosis (TB) needs testing and treatment
- You are coughing up thick green, yellow or bloody phlegm
- You wheeze, or you have asthma, heart disease or lung disease
- A baby under 3 months, or a young child, has a cough with fever or fast breathing
- A child has a “whooping” sound after coughing, or vomits after coughing fits
- You have swelling in the ankles, or you are a smoker with a cough that is changing
How to Prevent a Cough
- Wash your hands often with soap and water.
- Avoid smoke and polluted air, and wear a mask in very dusty places.
- Keep up with vaccines, such as the yearly flu vaccine, as advised by your doctor.
- Stay away from people who are unwell where possible.
- Support your body with sleep, activity and good food. See our guide on how to boost immunity naturally.
Frequently Asked Questions
What is the fastest home remedy for cough?
Honey in warm water (for people over one year old), warm fluids and moist air give the quickest comfort for many people. None of them cures the infection, but they can ease the cough.
Are home remedies for cough safe for children?
Some are, such as fluids, rest and moist air. Honey is safe only after 12 months, lozenges are not suitable for young children, and cough medicines should not be given to young children without medical advice.
Why is my cough worse at night?
Lying flat lets mucus drip down the throat and acid rise from the stomach, and the air in bedrooms is often dry. Extra pillows and a humidifier can help.
How long can a cough last after a cold?
A cough can last up to three weeks after the other cold symptoms have gone. See a doctor if it lasts longer or you feel worse.
Is a cough contagious?
If it is caused by an infection, yes. Wash your hands, cover your mouth when you cough and stay home while you have a fever. For related symptoms, see our guides on sore throat home remedies and home remedies for cold and flu.

Most coughs get better by themselves, and home remedies for cough such as honey for those over one year old, warm fluids, moist air, extra pillows and avoiding smoke can make you more comfortable while you heal.
