The “Abonit.d” website reported that nasal douches have many benefits, as they can remove dust, pollen, and other impurities, and also help dissolve mucus, and thus can relieve the symptoms of sinusitis, allergies, colds, and influenza.
The website, which is the official portal for German pharmacists, explained that when using a nasal douche, it is preferable to use only distilled, sterilized, or previously boiled and well-cooled water.
Tap water is not suitable, as it may contain small amounts of germs such as aquatic amoeba, which may be found in biofilms on the interior walls of water supply systems, which may cause severe infections.
Nasal douche water should also be enriched with table salt, because salt-free water may irritate the mucous membranes. Special additives are available in pharmacies.
How to use
Regarding how to use, Abonit.D explained that one should bend over the sink and move the head to the side to prevent any liquid from entering the open mouth, while breathing through the open mouth to prevent the lye solution from reaching the throat.
After that, the nozzle of the nasal douche device is placed on the upper nostril and the washing begins, while the liquid will drain through the lower nostril, then the side is switched. After completion, the device should be cleaned and dried well.
