The role of Nasal Douche

Physical cleaning and allergen removal --
Nasal Douche can effectively remove dust, pollen, bacteria, viruses and mucus secretions in the nasal cavity through the flow of physiological saline or special irrigating fluid, and reduce the retention of allergens and pathogens. For example, patients with allergic rhinitis can remove pollen and dust mites attached to the nasal mucosa by irrigating, reducing the frequency of allergic reactions. The mechanical flushing effect of the irrigating fluid directly removes particles and inflammatory mediators in the nasal cavity, such as histamine and leukotrienes, and relieves symptoms such as nasal itching and sneezing. Improve the function of nasal mucosal cilia. The cilia of the nasal mucosa help expel foreign matter by swinging, but their function is impaired during inflammation or infection. Flushing can dilute viscous secretions, restore the swinging ability of cilia, and accelerate nasal self-cleaning.

Reduce inflammation and promote repair --
Nasal irrigation can reduce the concentration of inflammatory factors in the nasal mucosa, relieve mucosal edema and congestion, and improve nasal congestion. For example, flushing can reduce purulent secretions and speed up the opening of the sinus opening in patients with acute sinusitis. Studies have shown that regular flushing can improve nasal symptoms by 27.66% and reduce medication use by 62.10%. Flushing can reduce the frequency of nasal hormone use and reduce drug side effects. For postoperative patients, flushing can remove blood scabs and secretions and promote wound healing.
