A cough can interrupt sleep and leave your throat feeling sore. Home care may make a mild cough more comfortable, but it does not treat every possible cause. The most useful starting point is to check for warning signs, then choose simple measures suited to your age and symptoms.
Get urgent medical advice if you cough up blood, have chest pain, find breathing difficult, or feel very unwell. Call your local emergency number for severe breathing difficulty, blue or grey lips, or sudden confusion. Do not wait for a home remedy to work.

What can help a mild cough at home?
1. Rest and drink fluids
Rest while you feel unwell and drink water regularly. Warm drinks can be comforting; let them cool enough to sip safely. These are supportive measures, not a cure for the infection or another condition causing the cough.
2. Try honey if you are at least one year old
Honey may ease a cough, although evidence is limited. Adults can try a warm drink with one or two teaspoons of honey and some lemon if desired. Never give honey to a baby younger than 12 months. Do not give hot drinks to small children. Honey is an optional comfort measure, not an antibiotic or a way to eliminate an infection.
3. Use saline for a blocked nose
If a cold also causes nasal congestion, saline nasal spray or drops may help with that symptom. Choose an age-appropriate product and follow its instructions. Treating a blocked nose does not establish why you are coughing.
4. Consider a clean cool-mist humidifier
A clean humidifier or cool-mist vaporizer is another option for cold symptoms. Follow the manufacturer’s cleaning instructions. There is no need to improvise a steam treatment with a bowl of boiling water.
5. Soothe an accompanying sore throat
Adults can gargle with half a teaspoon of salt dissolved in a glass of warm water, then spit it out. This is for throat discomfort; it is not a proven treatment for the underlying cough. Children should not try this. Lozenges may also soothe the throat, but do not give them to children under four because of choking risk.
6. Avoid smoking
Smoking can worsen respiratory symptoms. Avoid smoking while recovering, and ask a healthcare professional for support if you would like help stopping.
Remedies we no longer recommend as established cough treatments
An earlier version of this article presented 18 remedies as effective treatments. That overstated what the evidence supports. It included claims that vinegar balances the body’s pH and that foods, herbs, or essential-oil mixtures fight the infection causing a cough. Those claims and treatment recipes have been removed.
Avoid leaning over bowls of hot or boiling water. NHS burns specialists warn that spills can cause serious scalds, particularly in children. They also report little evidence of meaningful benefit from steam inhalation. We have removed the previous towel-over-the-head instructions.
We also no longer recommend homemade essential-oil chest rubs or herbal dosing recipes here. If you are considering a herbal product, ask a pharmacist whether it is suitable, especially during pregnancy or when taking other medicines. “Natural” is not a substitute for checking safety and evidence.
Should you take cough medicine or antibiotics?
A pharmacist can help you choose a product appropriate to your symptoms and age. Some medicines offer temporary symptom relief; they do not cure the illness. Read the label and check suitability with a professional rather than combining several products yourself.
The CDC advises against over-the-counter cough and cold medicines for children younger than six. Product age restrictions vary, so ask a child’s clinician or pharmacist for guidance. Do not use an adult medicine or dose for a child.
Antibiotics do not treat viruses. A clinician may prescribe them when a bacterial infection or another specific indication is identified. A lingering cough alone is not a reason to use leftover antibiotics.
When should a cough be checked?
The NHS notes that many coughs clear within three to four weeks, but recommends seeing a clinician if yours lasts more than three weeks. Arrange an assessment sooner if it is worsening, you are losing weight without trying, or your immune system is weakened.
For cold-like illness, seek advice for dehydration, fever lasting more than four days, symptoms that do not improve after ten days, or symptoms that improve and then return or worsen. People at higher risk from flu or COVID-19 should contact a clinician promptly because treatment can be time-sensitive.
Coughs can also be associated with reflux, allergies, smoking, or mucus draining down the throat. Repeatedly switching home remedies can delay finding the cause. Tell your clinician how long the cough has lasted and what other symptoms you have.
