Saline nasal irrigation is a simple process that involves rinsing the nasal passages with a saltwater solution. This method helps to clear out mucus, allergens, and irritants, making it easier to breathe. It is often used to relieve symptoms of allergies, sinusitis, and colds. The saline solution can be administered using a neti pot, squeeze bottle, or bulb syringe. Regular use of saline nasal irrigation can improve nasal hygiene and overall respiratory health. It is generally safe for most people, but those with certain medical conditions should consult a healthcare professional before starting.
