Most sore throats are caused by viral infections and will resolve on their own within five to seven days. In the meantime, several remedies can meaningfully reduce your pain and discomfort. What works best depends on whether you’re dealing with inflammation, dryness, or a bacterial infection, so it helps to understand what’s actually happening in your throat before reaching for relief.
Why Your Throat Hurts
When a virus takes hold in your throat, your immune system launches an inflammatory response. Your body produces pain-signaling molecules, including bradykinin, that directly stimulate nerve endings in the throat tissue. This is why a sore throat can feel raw and burning even when there’s no visible damage. The swelling and increased blood flow that come with inflammation make nerve endings even more sensitive, so swallowing, talking, or even breathing dry air can amplify the pain.
Understanding this helps explain why the most effective remedies work on multiple fronts: reducing inflammation, numbing nerve endings, or physically coating and protecting irritated tissue.
Salt Water Gargle
A warm salt water gargle is one of the simplest and most effective things you can do. Mix half a teaspoon of salt into one cup of warm water, gargle for 15 to 30 seconds, and spit it out. The salt draws excess fluid out of swollen throat tissue through osmosis, which reduces inflammation and eases pain. It also loosens mucus and can flush out irritants. You can repeat this several times a day as needed.
Honey
Honey coats and soothes the throat, and it has mild antibacterial and anti-inflammatory properties. A systematic review published in BMJ Evidence-Based Medicine found that honey provided meaningful symptom relief for upper respiratory infections compared to usual care. Its thick consistency forms a protective layer over irritated tissue, which is partly why it works well stirred into warm tea or taken by the spoonful. It performed comparably to the active ingredient in many over-the-counter cough syrups in studies, though the evidence wasn’t strong enough to say it’s clearly superior.
One important caveat: never give honey to children under one year old due to the risk of botulism.
Over-the-Counter Pain Relief
Standard pain relievers like ibuprofen and acetaminophen work well for sore throats because they target the inflammatory process itself. Ibuprofen is particularly effective since it reduces both pain and swelling. For sore throats specifically, many people find that alternating between the two provides steadier relief throughout the day, since they work through different mechanisms.
Throat lozenges containing numbing agents like benzocaine provide temporary local relief by blocking pain signals from the nerve endings in your throat. The numbing effect kicks in within minutes and lasts through the time it takes the lozenge to dissolve. These are especially useful right before meals if swallowing is painful. Lozenges without a numbing agent still help by stimulating saliva production, which keeps the throat moist and washes away irritants.
Zinc Lozenges
If your sore throat is part of a cold, zinc lozenges started within the first 24 hours of symptoms may shorten the overall duration of illness. The effective dose in studies is 75 to 100 milligrams of elemental zinc per day, divided into doses every two to three hours while awake, for up to five to seven days. Check the label for “elemental zinc” content, since the total milligrams of zinc gluconate or zinc acetate listed on the package is not the same number. Zinc lozenges can cause nausea on an empty stomach and leave a metallic taste, so they’re not for everyone.
Keep Your Throat Moist
Dry air is one of the biggest aggravators of a sore throat, especially overnight. A humidifier in your bedroom can make a noticeable difference. The Mayo Clinic recommends keeping indoor humidity between 30% and 50%. Higher than that encourages mold and dust mite growth, which can make things worse. If you don’t have a humidifier, a hot shower before bed serves a similar purpose for the short term.
Staying well hydrated matters too. Warm liquids like tea, broth, and warm water with lemon are particularly soothing because the warmth increases blood flow to the throat tissue and the liquid keeps the mucous membranes from drying out. Cold liquids and ice pops work differently but can also help by temporarily numbing the area. Avoid alcohol and caffeine, which are dehydrating.
Herbal Throat Coaters
Some herbs contain a gel-like substance called mucilage that physically coats the throat when you swallow, creating a protective barrier over irritated tissue. Marshmallow root and slippery elm are the two most widely available options, typically sold as teas or lozenges. The coating effect is temporary but can provide noticeable relief, especially for that dry, scratchy feeling. These work well combined with honey in a warm tea.
When a Sore Throat Might Be Bacterial
About 70% to 80% of sore throats in adults are viral and don’t need antibiotics. Strep throat, caused by group A streptococcal bacteria, is the main bacterial concern. Doctors use a simple scoring system to estimate the likelihood of strep based on four features: fever above 100.4°F, swollen and tender lymph nodes at the front of the neck, white patches or swelling on the tonsils, and the absence of cough. A person with none or one of these features has roughly a 7% to 12% chance of having strep. Someone with all four has about a 57% chance, which is why a rapid strep test is still needed to confirm the diagnosis even when symptoms look suspicious.
If you have a cough, runny nose, and hoarseness along with your sore throat, a virus is almost certainly the cause. Strep tends to come on suddenly with throat pain and fever but without the typical cold symptoms.
Red Flags That Need Immediate Attention
Most sore throats are harmless, but a few warning signs point to something more serious. Difficulty breathing, a high-pitched whistling sound when inhaling, drooling because you can’t swallow, a muffled or “hot potato” voice, or the inability to open your mouth fully all suggest a possible airway emergency like epiglottitis or a peritonsillar abscess. These conditions can worsen rapidly and require emergency care. A sore throat that is only on one side, is getting significantly worse after three to four days instead of better, or comes with a persistent fever above 101°F also warrants a call to your doctor.
