Cleansing the Nasal Cavity
Nasal cleansing solutions use physiological osmotic pressure to rinse the nasal cavity, effectively removing dust, pollen, bacteria, and other foreign objects. For those with allergic rhinitis, regular rinsing can reduce allergen retention and relieve sneezing and nasal itching. Common rinsing methods include sprays and irrigation; sprays are more suitable for children or those with sensitive skin.
Moisturizing the Mucous Membranes
Solutions containing sodium chloride or sea salt maintain the moisture of the nasal mucosa, improving nasal crusts and nosebleeds caused by dry rhinitis. For those who spend long periods in air-conditioned environments or dry climates, daily use can prevent nasal cracking. Some products add glycerin or hyaluronic acid to enhance moisturizing effects.
Diluting Secretions
Hypertonic solutions dilute thick nasal secretions, relieving nasal congestion symptoms during sinusitis or colds. By reducing the viscosity of secretions, they promote nasal drainage and reduce the probability of secondary infections. For those with acute rhinitis, combining with warm steam inhalation yields better results.
