A nasal shower offers several benefits, as it can remove dust, pollen, and other impurities, and it helps to dissolve mucus, thereby alleviating the symptoms of sinusitis, allergies, colds, and flu. According to the German pharmacists' portal 'Apotheke.de,' when using a nasal shower, 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 amoebas, which can be present in the biofilm on the inner walls of water supply systems and can cause a severe infection. It is also necessary to enrich the nasal shower water with table salt, as salt-free water can irritate the mucous membranes. Special additives are available in pharmacies. Regarding how to use it, 'Apotheke.de' explains that one should bend over the sink and turn the head to the side to prevent any liquid from entering the open mouth, while breathing through the open mouth to prevent the irrigation solution from reaching the throat. Afterwards, the nozzle of the nasal shower device is placed in the upper nostril and washing begins, while the liquid will drain through the lower nostril, then the side is switched. After finishing, the device should be cleaned and dried thoroughly. When using a nasal shower, it is preferable to use only distilled, sterilized, or previously boiled and well-cooled water.
