Regular practice of nasal irrigation with salt water is presented as an essential tool for eliminating allergens, reducing the frequency of respiratory infections, and maintaining optimal sinus hygiene, especially in dusty environments.

The scientific community strongly agrees on this practice, which is considered an effective lever for respiratory comfort. Scientifically, saline nasal irrigation is a recognized practice for helping to clear mucus and irritants (dust, pollen), which is supported by various systematic reviews (such as Cochrane) confirming an improvement in symptoms for chronic rhinosinusitis. While the effect on comfort is well-documented, the notion that it systematically prevents viral infections remains nuanced, as the evidence is variable depending on the context and frequency. It is crucial to note that the major risk lies in water quality: the use of untreated water (tap water) is formally advised against by health authorities to avoid rare but serious contamination by amoebas, validating the members' insistence on distilled or boiled water. The addition of baking soda is a common practice to adjust pH, although its impact is more a matter of comfort during rinsing than a strict therapeutic necessity. In short, the method is sound for maintenance and relief, as long as drastic hygiene precautions are respected.
