Does Nasal Irrigation Effectively Fight the Common Cold?

As the winter season progresses, so does cold season.

When we come down with a cold, we try different methods to relieve our cold symptoms.

However, using a simple saline or saltwater solution can help reduce the duration of these symptoms.  

A pilot study conducted in 2019 found that flushing the nose with a 3% saline solution, which is higher than the standard 0.9% concentration, can reduce cold symptoms in approximately two days.  

Additionally, researchers say that saline nasal drops may help reduce transmission rates of cold viruses.  

In the same 2019 study, 93% of participants reported that the 3% saline solution made a difference in their symptoms, and 61% indicated that they would use it again during another cold.  

Most people may catch a cold two or three times each year, as the cold virus spreads easily via contaminated droplets. Saline solution is an affordable, easy-to-use treatment that may help slow down the spread of the cold virus between family members.  

Saline nasal drops may also help to clear up a runny nose. The solution may help reduce viral load, the amount of the virus in a person’s system, by flushing out the nasal passages.  

Saline nasal drops help flush out mucous and inflammatory mediators, which are chemical messengers that play a crucial role in initiating and regulating the body’s inflammatory response. This can improve cold symptoms and give the immune system a better chance to fight the infection.  

When you are looking to buy saline nasal drops or sprays, it is important to look for a saline percentage or the words “hypertonic” or “extra-strength” on the label. Many brands of saline solutions sell 3% hypertonic nasal spray, but it is important to read the labels carefully to confirm the product does not contain other added medications.  

You can also make a saline solution at home with salt, baking soda, and water. It is important to only use distilled or boiled and cooled tap water when preparing the solution, as the quality of tap water varies, and there may be things such as bugs and germs present.  

To make the saline solution, combine three tablespoons of salt and one teaspoon of baking soda. Avoid any salts that contain iodine, preservatives, or anti-caking agents because these can irritate your nose. Put one teaspoon of the salt-baking soda mixture into eight ounces of distilled or boiled water. Baking soda helps reduce irritation; however, you may still experience some irritation in the nose or throat after using the saline solution.  

Although hypertonic nasal drops or sprays could be prepared correctly, they can still irritate the nose and throat. Some people may even experience a temporary burning sensation. Use the hypertonic saline solution as tolerated. It is important to talk to your healthcare provider about alternative cold remedies if the saline solution doesn’t work well for you and if your cold symptoms persist or get worse.
