A neti pot is a small, teapot-shaped device used to flush saline solution through your nasal passages. Originally an Ayurvedic health tool from India, it has become one of the most widely used home remedies for nasal congestion, sinus pressure, and allergies. The basic idea is simple: you pour saltwater into one nostril, and it flows through your nasal cavity and out the other nostril, washing away mucus, allergens, and irritants along the way.
How Nasal Irrigation Works
The neti pot works primarily as a mechanical cleaning tool. Saline solution softens and dislodges the mucus lining your nasal cavity, physically flushing it out. Along with the mucus, the rinse removes inflammatory compounds (like those that cause swelling and congestion) and allergens that trigger reactions. A low-salt or isotonic rinse also reduces the number of bacteria and other microbes living in the nasal passages, which can help your body recover faster from infections.
The salt and other minerals in the solution play supporting roles. Magnesium promotes cell repair and limits inflammation. Potassium has anti-inflammatory effects. Baking soda, often added to homemade solutions, helps reduce mucus thickness so it’s easier to clear. Together, these ingredients support the health of the cells lining your nasal passages, not just the cleaning process itself.
What It Helps With
People typically reach for a neti pot when they’re dealing with sinus congestion from colds, chronic sinusitis, or seasonal allergies. The rinse can relieve stuffiness, reduce postnasal drip, and ease sinus pressure without medication. It’s also commonly used by people with dust or pollen sensitivities to wash irritants out of their nose at the end of the day. Some people use it daily as a preventive measure, while others use it only when symptoms flare up.
How to Make the Saline Solution
You can buy premixed saline packets, but making your own is straightforward. Start with one cup of distilled, sterile, or previously boiled water (cooled to lukewarm). Stir in half a teaspoon of non-iodized salt, such as sea salt, and half a teaspoon of baking soda until both dissolve completely. The baking soda buffers the solution so it’s gentler on your nasal lining. If you skip the salt or get the ratio wrong, the rinse will sting.
How to Use a Neti Pot
Lean over a sink and tilt your head to one side at roughly a 45-degree angle. Place the spout of the neti pot snugly into your upper nostril. Breathe through your mouth, then pour the solution steadily. It will flow through your nasal cavity and drain out your lower nostril. Use about half the solution on one side, then switch to the other nostril. Gently blow your nose afterward to clear any remaining liquid.
The process feels strange the first time, but it shouldn’t be painful. If you feel pressure in your ears, you’re tilting your head too far forward. If the solution burns or stings, reduce the amount of salt or double-check that the water has cooled enough. After each use, rinse the neti pot itself with distilled, sterile, or previously boiled water and let it air dry completely.
The Water You Use Matters
This is the single most important safety rule: never use plain tap water in a neti pot. Tap water contains low levels of bacteria, protozoa, and amoebas that are harmless when swallowed because stomach acid destroys them. But inside your nasal passages, these organisms can survive and cause serious infections.
The most dangerous of these is a brain-eating amoeba called Naegleria fowleri, which causes a rare but almost always fatal brain infection called primary amebic meningoencephalitis. The CDC has documented fatal cases linked specifically to nasal irrigation with contaminated tap water. While these infections are extremely rare, they are entirely preventable.
Safe water options include:
- Distilled or sterile water purchased from a store (the label will say “distilled” or “sterile”)
- Boiled tap water that has been boiled for 3 to 5 minutes, then cooled to lukewarm. Previously boiled water can be stored in a clean, closed container for up to 24 hours.
- Filtered water passed through a filter rated at 1 micron or smaller, or labeled NSF 53, NSF 58, or “cyst removal”
Side Effects and When to Skip It
The most common complaint is a mild burning or stinging sensation. This usually means the salt concentration is too high or the water is too warm or too cool. Adjusting the amount of salt and making sure the water is lukewarm typically solves it.
You should avoid nasal irrigation entirely if you have an ear infection, pressure in one or both ears, a completely blocked nostril, or have had recent surgery on your ears or sinuses. If your symptoms aren’t improving after regular use, or if you develop a fever or headache, that’s worth a conversation with your doctor, as it may signal an infection that needs different treatment.
