Most sore throats are caused by viral infections and will clear up on their own within five to seven days. In the meantime, a combination of anti-inflammatory pain relievers, warm or cold liquids, honey, and saltwater gargles can significantly reduce pain and swelling. Here’s what actually works and why.
Anti-Inflammatory Pain Relievers Work Best
If you want the single most effective option, reach for ibuprofen. It’s a nonsteroidal anti-inflammatory, which means it targets both the pain and the swelling at the back of your throat. As Yale Medicine notes, ibuprofen directly reduces inflammation in the pharynx, making it the top choice for viral sore throats. If you can’t take ibuprofen (due to stomach sensitivity or other reasons), acetaminophen is a reasonable alternative. It helps with pain but doesn’t reduce inflammation as effectively.
Saltwater Gargles
Dissolve half a teaspoon of salt in one cup of warm water and gargle for 15 to 30 seconds. The salt draws excess fluid out of swollen throat tissue through osmosis, temporarily reducing puffiness and easing that tight, painful feeling. It also loosens thick mucus and can flush irritants from the throat surface. You can repeat this several times a day. It won’t cure anything, but the relief is fast and essentially free.
Honey Outperforms Some Cough Medicines
Honey coats and soothes irritated throat tissue, and the evidence behind it is stronger than you might expect. A systematic review published in BMJ Evidence-Based Medicine found that honey performed about as well as dextromethorphan (the active ingredient in many cough syrups) for reducing cough frequency and severity. Against diphenhydramine, another common ingredient in nighttime cold medicines, honey actually performed significantly better across all measured symptoms.
A spoonful of honey straight, or stirred into warm tea, is a simple and effective option, especially before bed when throat irritation tends to feel worse. One important exception: never give honey to children under one year old. Honey can contain bacterial spores that cause infant botulism, a serious illness. Older children and adults process these spores without issue.
Hot Drinks, Cold Drinks, or Both
You don’t have to choose between warm and cold. Both work, just through different mechanisms. Cold liquids and ice chips narrow blood vessels, reduce swelling, and numb sore tissue. Warm liquids open blood vessels, improve circulation to the area, and relax the surrounding muscles. A small 2008 study found that a hot drink relieved sore throat symptoms noticeably better than the same drink served at room temperature.
The practical advice is simple: drink whichever temperature feels better to you. Warm broth, herbal tea with honey, ice water, popsicles, or smoothies all keep you hydrated and provide some degree of throat relief. Staying well-hydrated also keeps the mucous membranes moist, which prevents that raw, scratchy feeling from getting worse.
Throat Lozenges and Sprays
Lozenges work in two ways. Some contain local anesthetics like benzocaine or lidocaine, which temporarily numb the throat tissue. These provide real pain relief, though they can also numb your tongue and affect your sense of taste. Menthol lozenges create a cooling sensation and have mild anesthetic properties of their own. Even plain hard candy or cough drops help by stimulating saliva production, which keeps the throat lubricated.
Throat sprays with numbing agents deliver a more targeted dose to the back of the throat. They’re especially useful right before meals if swallowing is painful.
Humidity and Your Environment
Dry air pulls moisture from your throat lining, making soreness worse. Running a humidifier in your bedroom can help, particularly during winter when indoor heating dries out the air. Warm-mist and cool-mist humidifiers are equally effective at adding moisture to the air. By the time the vapor reaches your airways, it’s the same temperature regardless of the type. For households with children, always use a cool-mist humidifier to avoid burn risks from hot water or steam.
Zinc Lozenges for Cold-Related Sore Throats
If your sore throat is part of a cold, zinc lozenges may shorten the duration of your symptoms. The effective dose in clinical research 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. Zinc works best when started within the first 24 hours of symptoms. Look for zinc gluconate or zinc acetate lozenges specifically. Taking zinc on an empty stomach can cause nausea, so keep that in mind.
Herbal Options That Coat the Throat
Marshmallow root tea and slippery elm lozenges contain natural mucilages, gel-like substances that form a thin protective coating over irritated throat tissue. This physical barrier shields raw nerve endings from further irritation and can make swallowing more comfortable. These won’t fight the underlying infection, but they provide a soothing layer that many people find helpful between doses of pain medication. You’ll find both as teas, lozenges, or supplements in most health food stores.
When a Sore Throat Might Be Strep
Most sore throats are viral, but strep throat is a bacterial infection that requires antibiotics. Doctors use a set of clinical criteria to estimate the likelihood of strep: fever above 100.4°F, swollen or pus-covered tonsils, tender swollen lymph nodes at the front of the neck, and the absence of a cough. The more of these signs you have, the higher the probability. Someone with all four criteria plus being between ages 3 and 44 has roughly a 50% chance of having strep. Someone with none of them has about a 1 to 2.5% chance.
If you have a cough, runny nose, and hoarseness along with your sore throat, it’s almost certainly viral, and the remedies above are your best bet. If you have a high fever, no cough, and can see white patches on your tonsils, a rapid strep test can give you an answer in minutes.
