This One COVID Safety Measure Doesn't Work, New Study Finds

But other remedies can actually provide protection against COVID, according to the research.


Throughout the course of the pandemic, there have been plenty of theories and tips circling around about certain home remedies or hygiene habits that may provide a level of protection against coronavirus. One of the most commonly proposed has been nasal saline washes like the neti pot. However, while researchers believed in the potential benefit flushing your nasal passages could have on reducing virus levels and mitigating symptoms of COVID-19, the results of a new study out of Penn State University indicate otherwise.

For the Sept. 2020 study published in the Journal of Medical Virology, researchers set out to determine the efficacy of common 0ver-the-counter mouth and nasal washes in regards to their ability to lessen the amount of the virus in the respiratory systems of patients with COVID-19. Unfortunately, the results showed that neti pots "had no effect on the infectivity of the virus at any incubation time tested."

But don't get discouraged just yet. The study found several products to be quite effective at fighting off COVID in infected patients. So, put the neti pot back in the cupboard for now and turn your attention to these other methods proven to kill COVID.
