Does putting salt water in your nose kill germs?

Putting salt water in your nose, often referred to as saline nasal irrigation, can help reduce nasal congestion and promote sinus health. The saline solution can flush out mucus and irritants, potentially reducing the presence of some germs. However, it is not a guaranteed method to kill all germs, and it should not replace proper hygiene practices or medical treatments when necessary. Always consult a healthcare professional for persistent issues or infections.
