Introduction
Seawater refers to physiological seawater nasal sprays or similar seawater preparations used for nasal irrigation. The correct steps for using seawater to wash the nose generally include cleaning and preparation, adjusting posture, aiming at the nostrils, pressing to spray and rinse, and wiping and tidying up. When using seawater to wash the nose, attention should be paid to frequency—usually once or twice daily is sufficient.
Saline solution refers to physiological seawater nasal sprays or similar saline preparations used for nasal irrigation. The correct steps for using saline solution to wash the nose typically include cleaning and preparation, adjusting posture, positioning the nozzle, pressing and rinsing, and wiping and tidying up. Details are as follows:
1. Cleaning and Preparation: Wash your hands thoroughly before use to avoid introducing bacteria into the nasal cavity. Check that the saline product packaging is intact and confirm it is within its expiration date. If using a spray, shake the bottle gently to ensure the solution is evenly mixed, ensuring safe and hygienic use.
2. Adjusting Posture: Tilt your head slightly forward with your chin tucked in. You may also tilt your head to one side so that one nostril faces downward. This position allows the saline solution to flow out smoothly and prevents the liquid from running into the throat, which could cause discomfort. Have tissues ready to wipe away any discharged fluid.
3. Positioning the Nozzle: Hold the saline product and gently aim the nozzle or rinse tip toward the downward-facing nostril. Maintain a slight angle (avoid inserting vertically) and keep the nozzle about 1–2 cm from the nostril to prevent direct contact with the nasal mucosa, reducing the risk of irritation.
4. Pressing and Rinsing: Gently press the spray nozzle or squeeze the bottle according to the product instructions, allowing the saline solution to flow slowly into the nasal cavity. Apply moderate pressure—avoid squeezing too hard, as excessive force may damage the nasal lining. After spraying, maintain the posture for a moment to allow the saline solution to fully moisten the nasal passages and flush out mucus and debris.
5. Wiping and Tidying Up: After rinsing, return your head to a neutral position and gently wipe away any流出 saline solution and secretions with a tissue. Then switch to the other nostril and repeat the same steps. After completion, wash your hands again and store the saline product properly.
When using saline nasal rinses, pay attention to frequency—generally once or twice daily is sufficient. Overuse may disrupt the natural environment of the nasal cavity. If you experience nasal pain, bleeding, or other discomfort after use, discontinue immediately and consult a healthcare professional. Select the appropriate saline product formulation based on age group to ensure proper suitability.
