Choose a comfortable temperature and avoid liquids that are hot enough to burn your mouth or throat.
The key takeaway: adequate hydration can help make thick secretions easier to manage, but drinking excessive amounts of water will not necessarily eliminate persistent mucus.
3. Gargle With Warm Salt Water
Gargling with salt water is a simple home remedy that may relieve throat irritation and help clear mucus from the surface of the throat.
It is particularly useful when mucus is accompanied by a scratchy feeling, mild soreness, or irritation associated with a respiratory infection.
How to prepare a saltwater gargle
-
Pour approximately 240 milliliters, or one cup, of warm water into a clean glass.
-
Add about half a teaspoon of salt.
-
Stir until the salt dissolves.
-
Take a small mouthful and gargle gently.
-
Spit the solution out rather than swallowing it.
You can repeat this as needed if it feels helpful.
Use warm water rather than very hot water, and do not force yourself to gargle if it causes discomfort.
Young children and anyone who cannot reliably gargle and spit should not use this method because of the risk of swallowing or choking.
Why might it help?
Saltwater gargling can help soothe irritated tissues and wash away some mucus and other material from the throat's surface.
It does not remove mucus from the lungs, treat every cause of postnasal drip, or eliminate the underlying cause of a persistent cough.
Nevertheless, it is inexpensive, easy to prepare, and may provide temporary relief.
If your throat symptoms are severe, persist, or occur alongside fever or difficulty swallowing, do not rely on gargling alone.
4. Try a Saline Nasal Spray or Rinse
If you frequently feel mucus dripping down the back of your throat, the problem may originate in your nose or sinuses rather than in your throat itself.
In that case, a saline nasal spray or rinse may be more helpful than repeatedly trying to cough up the mucus.
Saline solutions help moisturize the nasal passages and wash away some mucus, allergens, and irritants. They may be particularly useful for people with nasal congestion, allergies, or postnasal drip.
Saline spray
A commercially prepared saline spray is a convenient option.
Follow the product instructions and avoid sharing the spray bottle with other people.
Saline sprays are generally used to moisturize the nasal passages and help loosen secretions without the medication ingredients found in some decongestant sprays.
Nasal irrigation
Nasal irrigation uses a saline solution to flush mucus and debris from the nasal passages.
If you use a neti pot, squeeze bottle, or another irrigation device, water safety is essential.
Use distilled or sterile water, or water that has been boiled and then allowed to cool. Do not use untreated tap water for nasal irrigation.
Prepare the solution according to the device instructions, clean the equipment properly after use, and allow it to dry.
If you have recently undergone nasal surgery, have significant nasal blockage, or are unsure whether irrigation is suitable for you, ask a healthcare professional first.
When is nasal rinsing most useful?
It may help when throat mucus occurs alongside:
-
A blocked or runny nose.
-
Sneezing or allergy symptoms.
-
A feeling of drainage behind the nose.
-
Nasal congestion after a cold.
-
Sinus discomfort associated with mucus buildup.
If the sensation persists despite appropriate nasal care, consider whether allergies, reflux, or another condition may be contributing.
5. Use Honey to Soothe Throat Irritation
Honey is a familiar home remedy for coughing and throat discomfort.
Its thick texture can coat the throat temporarily, and some people find that it reduces the urge to cough, particularly when symptoms interfere with sleep.
You can try a small spoonful of honey on its own or mix it into warm water or caffeine-free tea.
Lemon can be added for flavor if you enjoy it, although lemon is not necessary for honey to provide soothing effects.
What honey can and cannot do
Honey may help soothe an irritated throat and relieve some cough symptoms. However, it is not a proven treatment for every cause of excess mucus.
It does not eliminate bacterial infections, cure chronic sinusitis, or reliably resolve mucus caused by acid reflux.
If you have diabetes or need to limit sugar intake, remember that honey is still a source of sugar and should be included accordingly.
Important safety warning: Never give honey to a child younger than 12 months because of the risk of infant botulism.
For older children and adults, honey can be a reasonable comfort measure when used appropriately.
