Post-nasal drip can cause coughing as mucus drips down into the lungs.

“Post-nasal drip is what happens when the sinuses make so much mucus that the mucus runs down the back of your throat, and it can cause a chronic cough known as upper airway cough syndrome (UACS). If you have a cough that won’t go away, along with nasal congestion, dripping mucus in your throat, a hoarse voice or morning “gunk” in the back of your throat, this may be you.” (Source:

But there is something you can do to help clean out the drip before it enters the lungs or an infection worsens. Use the old Utah pioneer treatment of rinsing your nasal passages with saltwater!

“Saltwater washes (saline lavage or irrigation) help keep the nasal passages open by washing out thick or dried mucus. They can also help improve the function of cilia that help clear the sinuses. This can help prevent the spread of infection to the other sinuses and reduce postnasal drip. It also can make the nose feel more comfortable by keeping the mucous membranes moist.

“You can buy saline nose drops at a pharmacy, or you can make your own saline solution:

– Add 1 cup (240 mL) distilled water to a clean container. If you use tap water, boil it first to sterilize it, and then let it cool until it is lukewarm.

– Add 0.5 tsp (2.5 g) salt to the water.

– Add 0.5 tsp (2.5 g) baking soda.

“You can store homemade saline solution at room temperature for 3 days.

“To use homemade saline solution as a nasal wash:

“Fill a large medical syringe, squeeze bottle, or nasal cleansing pot (such as a Neti Pot) with the saline solution, insert the tip into your nostril, and squeeze gently.

– Aim the stream of saline solution toward the back of your head, not toward the top.
The saline wash should go through the nose and out the mouth or the other side of the nose.

– Blow your nose gently after the saline wash unless your doctor has told you not to blow your nose.

– Repeat several times every day.

– Clean the syringe or bottle after each use.”
