Most sore throats are caused by viral infections and clear up on their own within about a week. The good news is that several home remedies and over-the-counter options can significantly reduce your pain while your body fights off the infection. Here’s what actually works.
Why Your Throat Hurts
A sore throat happens when the tissue lining your throat becomes inflamed, usually in response to a viral infection like a cold or the flu. Roughly 85% to 95% of sore throats in adults fall into this category, meaning antibiotics won’t help. The inflammation triggers pain receptors every time you swallow, talk, or even breathe through your mouth. Most symptoms resolve within three to ten days, with viral infections typically clearing within a week.
Bacterial infections, particularly strep throat, account for a smaller percentage. Doctors look for a specific pattern to distinguish strep from a viral cause: fever of 100.4°F or higher, swollen lymph nodes at the front of the neck, white patches or swelling on the tonsils, and the absence of a cough. If you have three or four of those signs, a rapid strep test can confirm the diagnosis. Strep does require antibiotics, so it’s worth knowing the difference.
Salt Water Gargle
Gargling with warm salt water is one of the simplest and most effective things you can do. Mix a quarter to a half teaspoon of table salt into eight ounces of warm water and gargle for 15 to 30 seconds before spitting it out. The salt creates a hypertonic solution, meaning the concentration of salt outside your throat cells is higher than inside them. This pulls excess water, mucus, and debris out of swollen tissue, temporarily reducing inflammation and pain. You can repeat this several times a day as needed.
Honey for Symptom Relief
Honey is more than a folk remedy. A systematic review of 14 studies found that honey improved overall symptom scores, reduced cough frequency, and lowered cough severity compared to usual care for upper respiratory infections. It coats and soothes irritated tissue, and its thick consistency helps calm the persistent tickle that can make a sore throat feel worse. A spoonful stirred into warm tea or taken straight works well. One important exception: never give honey to children under one year old due to the risk of botulism.
Over-the-Counter Pain Relievers
If you need stronger relief, anti-inflammatory pain relievers are your best bet. Ibuprofen reduces throat pain by 32% to 80% within two to four hours of a single dose, and by about 70% at the six-hour mark. It works well for sore throats because it targets both pain and the underlying inflammation causing it. Acetaminophen is also effective for pain but doesn’t address inflammation directly, so it may provide slightly less relief for a throat that’s visibly red and swollen.
Throat sprays and lozenges containing numbing agents offer a more targeted approach. The numbing sensation from a throat spray typically lasts about two hours per application, making them useful for getting through meals or falling asleep. They work best as a supplement to oral pain relievers rather than a replacement.
Keep Your Throat Moist
Dry air is one of the most overlooked aggravators of a sore throat. When indoor humidity drops below 30%, the mucous membranes in your nose and throat dry out, making irritation worse and slowing your body’s ability to trap and clear pathogens. If you’re running a heater or live in a dry climate, a humidifier can help. The ideal indoor humidity range is 30% to 50%. Higher than that encourages mold and dust mites, which create their own problems.
Staying hydrated matters just as much. Warm liquids like broth, tea, or plain warm water soothe the throat and keep mucus thin so it drains more easily. Cold liquids and ice pops can also help by temporarily numbing the area. What you want to avoid is anything that dehydrates you further, like alcohol or excessive caffeine.
Other Strategies That Help
Rest your voice. Talking, whispering (which actually strains the vocal cords more than speaking softly), and clearing your throat all increase irritation. Give your throat as little work as possible.
Sleep with your head slightly elevated if postnasal drip is contributing to your sore throat. Mucus pooling in the back of your throat overnight is a common reason people feel worst in the morning.
Avoid cigarette smoke and other airborne irritants. Smoke directly damages the already-inflamed tissue and can extend your recovery time significantly.
When a Sore Throat Needs Medical Attention
Most sore throats don’t require a doctor’s visit, but certain symptoms signal something more serious. The CDC recommends seeking care if you experience difficulty breathing, difficulty swallowing, blood in your saliva or phlegm, excessive drooling in young children, signs of dehydration, joint swelling and pain, or a rash. A sore throat that doesn’t improve within a few days, or one that gets progressively worse instead of better, also warrants a visit. A fever above 101°F lasting more than a couple of days, particularly with swollen lymph nodes and no cough, suggests strep throat and should be evaluated with a rapid test.
