Most coughs from colds and upper respiratory infections clear up on their own within one to three weeks, and simple home treatments can make that wait far more comfortable. The goal is to soothe irritated airways, thin out mucus so your body can clear it, and get better sleep while you heal. Here’s what actually works.
Honey: The Best-Studied Home Remedy
Honey is one of the few home cough remedies with real clinical data behind it. In a trial of 105 children with upper respiratory infections, buckwheat honey reduced cough frequency, cough severity, and sleep disruption more effectively than no treatment. It also performed on par with the active ingredient in most over-the-counter cough syrups. Children who received honey saw roughly twice the improvement in combined symptom scores compared to those who got nothing at all.
For children ages 1 and older, half a teaspoon to one teaspoon of honey is the effective dose. You can give it straight or stir it into warm water, tea, or juice. Adults can take a tablespoon the same way. Honey coats the throat, which likely calms the nerve endings that trigger the cough reflex.
One firm rule: never give honey to a baby under 12 months. Honey can contain spores that cause infant botulism, a rare but serious form of food poisoning. The CDC advises against adding honey to a baby’s food, water, formula, or pacifier.
Stay Hydrated With Warm Fluids
Fluids thin mucus, and warm fluids do it a bit better than cold ones. Warm water, broth, herbal tea, or diluted juice all help loosen congestion in the chest and nose so you can cough it up more easily. Staying well-hydrated also keeps the throat moist, which reduces that dry, scratchy feeling that triggers coughing fits. There’s no magic number of cups per day, but if your urine is pale yellow, you’re drinking enough.
Salt Water Gargle for Throat Irritation
A salt water gargle draws excess fluid out of swollen throat tissue and helps flush away irritants. The ratio is simple: half a teaspoon of salt dissolved in one cup of warm water. Gargle for 15 to 30 seconds, spit it out, and repeat at least four times a day for two to three days. This won’t stop a deep chest cough, but it’s effective for the scratchy, post-nasal-drip type of cough that originates in the throat.
Humidity and Steam
Dry indoor air, especially in winter, irritates airways and thickens mucus. The EPA recommends keeping indoor humidity between 30 and 50 percent. A cool-mist humidifier in your bedroom can make a noticeable difference overnight. Clean it regularly to prevent mold and bacteria from building up in the water tank.
Steam can offer short-term relief from congestion, but the safest approach matters. Burns specialists at the NHS have warned against leaning over bowls of boiling water, noting that even a momentary slip can cause serious scalds. If you want steam therapy, sit in a closed bathroom with a hot shower running for 10 to 15 minutes instead. You get the same moist air without the burn risk.
Ginger Tea for Inflammation
Ginger contains compounds that work against inflammation in a way similar to common anti-inflammatory pain relievers. It blocks the production of chemical signals that drive swelling and irritation in the airways. Some of its active compounds also show antimicrobial properties in lab studies. To make ginger tea, slice a thumb-sized piece of fresh ginger, steep it in boiling water for 10 minutes, and strain. Adding honey gives you two remedies in one cup.
How to Stop Coughing at Night
Nighttime coughing is often the most disruptive part of being sick, and gravity is the main reason. When you lie flat, mucus from your sinuses drains down the back of your throat, triggering the cough reflex. The Cleveland Clinic recommends elevating your head as the single best adjustment for sleep. An extra pillow or a wedge under your mattress keeps drainage from pooling in your throat. Just don’t stack pillows so high that you wake up with neck pain.
A few other nighttime strategies help. Run a humidifier in the bedroom. Take a spoonful of honey shortly before bed. Keep a glass of water on the nightstand so you can sip if a coughing fit wakes you. And if your nose is congested, a saline nasal rinse before bed can reduce the post-nasal drip that’s feeding the cough in the first place.
What Not to Bother With
Over-the-counter cough suppressants are widely used but not strongly supported by evidence. In the clinical trial comparing honey to the standard OTC cough suppressant, the drug didn’t perform significantly better than no treatment at all in children. That doesn’t mean these products never help, but it does suggest they’re not clearly superior to honey and fluids for a typical viral cough. For children under six, most medical organizations recommend avoiding OTC cough and cold medicines entirely due to the risk of side effects.
Signs Your Cough Needs Medical Attention
Home remedies are appropriate for uncomplicated coughs from colds and mild respiratory infections. But certain symptoms signal something more serious. Contact a doctor if your cough lasts more than a few weeks or comes with any of the following:
- Thick, greenish-yellow phlegm
- Wheezing or shortness of breath
- Fever
- Ankle swelling or unexplained weight loss
- Fainting
Go to an emergency room if you’re coughing up blood or pink-tinged phlegm, having trouble breathing or swallowing, experiencing chest pain, or choking and vomiting. These can indicate pneumonia, a pulmonary embolism, or other conditions that need immediate treatment.
