Most sore throats and coughs are caused by viral infections and clear up on their own within a week to ten days. In the meantime, a combination of simple home remedies and the right over-the-counter products can make a real difference in how you feel. Here’s what actually works.
Honey for Cough Relief
Honey is one of the best-studied natural remedies for upper respiratory symptoms. A systematic review published in BMJ Evidence-Based Medicine found that honey performed about as well as dextromethorphan, the most common cough suppressant found in drugstore cough syrups. It also outperformed diphenhydramine (the active ingredient in some nighttime cough formulas) for cough frequency, cough severity, and overall symptom scores.
A spoonful of honey coats the throat and can calm a cough for long enough to help you sleep. You can take it straight, stir it into warm water, or mix it into tea with lemon. There’s no established “dose,” but one to two tablespoons at a time is what most studies have used. One critical safety note: never give honey to a child under one year old. Even tiny amounts can cause infant botulism, a rare but serious illness.
Salt Water Gargle
Gargling warm salt water is a simple, effective way to ease a raw throat. Salt draws fluid out of swollen tissues through osmosis, which reduces inflammation and that tight, painful feeling when you swallow. Dissolve half a teaspoon of salt in 8 ounces of warm (not hot) water and gargle for 15 to 30 seconds. You can repeat this several times a day. It won’t cure the infection, but it reliably takes the edge off.
Warm Fluids and Throat-Coating Remedies
Staying hydrated keeps your throat moist and helps thin mucus so it’s easier to clear. Warm liquids like broth, herbal tea, and warm water with lemon tend to feel more soothing than cold drinks, though either works for hydration. The warmth itself can loosen congestion and reduce that scratchy, dry sensation.
If you want something beyond basic fluids, marshmallow root tea is worth trying. Research has found that marshmallow root builds a protective coating over irritated tissue in the mouth and throat, reducing swelling and easing dry cough symptoms. You can find it as a loose tea or in pre-made throat-coat tea blends at most grocery stores. Slippery elm lozenges work through a similar coating mechanism.
Choosing the Right Over-the-Counter Medicine
Not all cough medicines do the same thing, and picking the wrong one means you’re not getting much benefit. The key is matching the product to your type of cough.
- Dry, hacking cough with no mucus: Look for a cough suppressant containing dextromethorphan. It works by quieting the cough reflex in the brain, which is helpful when the cough isn’t productive and is just keeping you up at night.
- Wet, chesty cough with mucus: Choose an expectorant containing guaifenesin. It thins mucus so you can cough it up more easily. You don’t want to suppress a productive cough because clearing that mucus is part of recovery.
For sore throat pain specifically, acetaminophen or ibuprofen will reduce both pain and inflammation. If you use acetaminophen, keep your total intake from all sources under 4,000 milligrams per day. This is easy to accidentally exceed because acetaminophen shows up in many combination cold and flu products. Check the labels of everything you’re taking.
Other Strategies That Help
A few additional approaches can make a noticeable difference, especially at night when symptoms tend to worsen.
Humidifying your air adds moisture that soothes irritated airways. A cool-mist humidifier in your bedroom, or even just spending a few minutes in a steamy bathroom, can loosen congestion and reduce coughing fits. Throat lozenges and hard candy stimulate saliva production, which keeps the throat coated and moist between drinks. Menthol lozenges add a cooling sensation that can temporarily numb throat pain. Propping your head up with an extra pillow at night helps prevent mucus from pooling in the back of your throat, which is often what triggers those middle-of-the-night coughing episodes.
How Long Symptoms Typically Last
A viral sore throat usually improves within three to seven days, though it can linger up to ten. Coughs tend to hang around longer than other symptoms. Even after you feel mostly better, a residual cough can persist for two to three weeks as your airways finish healing. This is normal and doesn’t necessarily mean something worse is going on.
However, certain symptoms signal that you should get checked out. Contact a doctor if your cough lasts more than a few weeks, or if you develop thick greenish-yellow phlegm, wheezing, fever, shortness of breath, or ankle swelling. Seek emergency care if you’re coughing up blood or pink-tinged phlegm, having trouble breathing or swallowing, or experiencing chest pain.
