What is a recommended practice to improve the efficacy of nasal irrigation?

Cleaning irrigation equipment with distilled water is recommended to improve the efficacy of nasal irrigation because it helps prevent the introduction of potentially harmful microorganisms present in regular tap water. Distilled water is free from impurities and pathogens, thereby reducing the risk of infections or other complications when performing nasal irrigation. Regular cleaning of the devices also ensures that any residual nasal secretions or contaminants are eliminated, further enhancing the safety and effectiveness of the irrigation process.

Using regular tap water can introduce bacteria and other harmful substances, while rinsing only once a month would not maintain the cleanliness of the equipment, making it less effective. Sharing irrigation devices can lead to cross-contamination, increasing the likelihood of infections as well. Therefore, utilizing distilled water for cleaning is the best practice to maximize the benefits of nasal irrigation.
