How can saline nasal spray help prevent colds and flu?

Dr. Mehmet Oz, MD

Airborne pathogens enter through your nose and mouth and begin to encroach on your body’s protective barriers. As they’re absorbed, they can spark an immune reaction and cause a cold or flu. The chances of getting sick are increased if your nasal passages are dry, a common occurrence in cold weather.

Without any lubrication, the nose can’t flush out bacteria, which results in a safe haven for germs. Saline nasal spray is a simple remedy that helps to flush out mucus and bacteria. Adding moisture to the nasal passages also helps to combat stuffiness, congestion, and further infection. Look for a spray that has purified water and sodium chloride to get the purest, most effective spray.
