A bad cough usually improves with a combination of home remedies, the right over-the-counter medication, and a few changes to your environment and sleeping setup. Most acute coughs from colds or bronchitis clear up within three weeks, but there’s plenty you can do in the meantime to get relief, especially at night when coughing tends to be worst.
Start With Honey and Warm Liquids
Honey is one of the most effective home remedies for cough, and it’s not just folk wisdom. A systematic review covering 934 patients found that honey was more effective than no treatment and at least as effective as over-the-counter cough suppressants. A single dose of about two teaspoons (10 grams) taken before bedtime is the approach most commonly studied, and it works well for nighttime cough relief. You can swallow it straight, stir it into warm tea, or mix it into warm water with lemon.
Warm liquids in general help thin out mucus sitting in your throat and chest. Soup, broth, and tea all work. Staying well hydrated throughout the day keeps secretions thinner and easier to clear, which reduces that heavy, rattling feeling in your chest.
One important exception: never give honey to a child under 12 months old. It carries a risk of infant botulism.
Choose the Right Over-the-Counter Medication
Cough medicines fall into two main categories, and picking the wrong one can work against you. Suppressants reduce the urge to cough, while expectorants thin your mucus so you can cough it up more easily. If your cough is dry and hacking with no mucus, a suppressant (the active ingredient is usually dextromethorphan, labeled “DM”) can help you rest. If your cough is wet and productive, an expectorant like guaifenesin helps loosen that congestion so your body can clear it out.
Avoid combination products that bundle both a suppressant and an expectorant together. That’s counterproductive: one ingredient is trying to stop your cough while the other is trying to make it more productive.
Cough Medicine and Children
The FDA does not recommend over-the-counter cough and cold medicines for children younger than 2 due to the risk of serious, potentially life-threatening side effects. Manufacturers voluntarily label these products with a warning not to use them in children under 4. The FDA also warns against homeopathic cough products for young children, noting reports of seizures, allergic reactions, and difficulty breathing in children under 4 who took them.
Soothe Your Throat With Saltwater
Gargling with warm saltwater draws fluid and irritants out of swollen throat tissue, which can calm the tickle that triggers coughing. Mix a quarter to half teaspoon of table salt into eight ounces of warm water, gargle for 15 to 30 seconds, and spit. You can repeat this several times a day. The salt creates a mildly concentrated solution that pulls moisture (and with it, debris and potentially viral particles) out of the inflamed cells lining your throat. There’s also evidence that the chloride ions in salt help immune cells produce a natural disinfectant, giving your body a small boost in fighting off infection.
Adjust Your Environment
Dry air irritates an already inflamed airway and makes coughing worse. A humidifier in your bedroom can help, but keep indoor humidity between 30% and 50%. Going above 50% encourages mold and dust mites, which can trigger more coughing. If you don’t have a humidifier, running a hot shower and sitting in the steamy bathroom for 10 to 15 minutes offers temporary relief.
Remove other airway irritants while you’re sick. Cigarette smoke, strong cleaning products, scented candles, and even cooking fumes can trigger coughing fits. Keep windows cracked if outdoor air quality is decent, and avoid anything with a strong chemical smell.
Fix Your Sleep Setup
Coughing almost always gets worse when you lie down. Gravity stops helping drain mucus from your sinuses and airways, so it pools in the back of your throat and triggers coughing. Propping your head and upper body up makes a noticeable difference. You can stack a few pillows, place a folded towel under your regular pillow, sleep in a recliner, or use an adjustable bed frame if you have one. The goal is to keep your head elevated enough that mucus drains down rather than sitting in your throat.
Sleeping on your side also helps, especially if you’re congested. If one nostril is more blocked than the other, sleep with the congested side facing up. So if your left nostril is stuffed, sleep on your right side. This simple positional trick can open up airflow and reduce the post-nasal drip that feeds nighttime coughing.
Address What’s Causing the Cough
If your cough has hung around longer than a typical cold, two common culprits are post-nasal drip and acid reflux (GERD). Both can cause a persistent cough that doesn’t respond to standard cold remedies.
Post-nasal drip happens when excess mucus from your sinuses drips down the back of your throat. Saline nasal sprays or a neti pot irrigation can thin out thickened secretions and flush irritants from your nasal passages. An expectorant like guaifenesin also helps make the mucus less sticky. Drinking warm liquids, especially soup and tea, keeps things moving.
Acid reflux causes coughing when stomach acid creeps up into your esophagus and irritates your throat, sometimes without any heartburn at all. If your cough is worse after meals or when lying down, reflux is worth considering. Practical steps that help: stop eating and drinking at least three hours before bed, elevate the head of your bed six to eight inches (not just your pillow, but the whole upper portion of the mattress or bed frame), cut back on caffeine and alcohol, and lose excess weight if that applies to you. Over-the-counter antacids or acid reducers can also make a difference.
Know When a Cough Needs Medical Attention
A cough lasting eight weeks or longer in adults, or four weeks in children, is classified as chronic and warrants a visit to your doctor. But you don’t need to wait that long if something feels off. Seek care sooner if your cough brings up blood or thick discolored sputum, disrupts your sleep night after night despite home remedies, or interferes with your ability to work or go to school. A cough paired with a high fever, significant shortness of breath, or chest pain also deserves prompt evaluation, as these can signal pneumonia or other conditions that need more than home care.
