Make your own nasal spray with salt and water.
Help clear up that sinus infection with an easy-to-make saline remedy. It works by helping rid you of excess mucus and allergens in your nostrils.
Start off by mixing three teaspoons of iodide-free salt with one teaspoon of baking soda, and a cup of lukewarm distilled water.
Next, grab a rubber ear bulb syringe and fill it up with the solution. Tilt your head and squeeze the solution into your nostril – it should come out the opposite nostril. Then apply the solution to the other nostril.
Make sure to see a doctor if your nasal congestion lasts longer than 10 days, comes with a high fever or if you notice green discharge.
