Sinus Rinse COVID-19 Information
There is emerging research suggesting that hypertonic nasal irrigation* is safe to use and possibly effective in decreasing the viral burden of SARS-CoV-2, as well as reducing the duration of symptoms and infection.** The studies observed that physically removing mucus through nasal irrigation helps to decrease viral burden and that NaCl has been found to have antiviral effects. Thus, research suggests that hypertonic nasal irrigation should be encouraged for patients and especially healthcare workers. To avoid possible infection with COVID-19 during nasal irrigation, users of nasal irrigation devices must practice good hand hygiene, decontaminate surrounding surfaces (e.g. sinks and counters) and thoroughly clean the devices prior to use.
The research is not conclusive and more studies are needed.
