1 cup water (ideally filtered)
1 tsp salt
Bring water to a boil. Boil for 10 minutes to get rid of any impurities.
Mix salt into the water and stir until dissolved.
Let the saline mixture cool.
Use in your nebulizer to assist with breathing issues. The moisture makes breathing easier, and the salt kills bacteria and viruses.
You can also put into a squeeze bottle and squeeze a few drops into each nostril to help clear up congestion.
You can also use this in a neti pot to do nasal irrigation to alleviate sinus issues and congestion in adults.
I did read about adding half a teaspoon of baking soda to the mix, but wasn’t sure about whether or not to add that for nebulizer use (as the store bought stuff is just salt and water), but feel free to add that when doing nasal irrigation with a neti pot.
