- Rinsing your nasal passages with a saline solution within 24 hours of a COVID-19 diagnosis could reduce your chances of being hospitalized by 8.5-fold
- Among people with COVID-19 who used nasal irrigation twice daily, 80% had zero or one mild symptom, compared to 42% of those who irrigated less often
- Only 13% of those who used nasal irrigation still had symptoms at day 28, compared to nearly 50% of those in another study
- Other research also supports the use of nasal irrigation as a “useful add-on to first-line interventions for COVID-19”
- Nebulized hydrogen peroxide diluted with saline, with or without iodine, can also be safely used by most people for prevention of respiratory infections — and in cases of active infection
Simple Way to Reduce Your Risk of COVID HospitalizationNasal irrigation, sometimes referred to as nasal lavage, is a relatively popular method for relieving cold symptoms, often via the use of a neti pot. The practice is an ancient technique with roots in the traditional Indian health care system, however.
They were randomly selected to use either one-half teaspoon of sodium bicarbonate (alkalinization) with an isotonic normal saline (0.9% saline) rinse twice a day for 14 days or to include 2.5 milliliters (roughly a half-teaspoon) of povidone-iodine (PVP-I) 10% solution (antimicrobial) for the same period. The researchers then followed up with each group 14 days after their final intervention.
Those who used nasal irrigation were more than 8.5 times less likely to be hospitalized compared to the national rate, the study found. A dose-response relationship was also found. Among those who irrigated twice daily, 80% had zero or one mild symptom, compared to 42% of those who irrigated less often.
"Our results support that pressurized nasal irrigation reduces the likelihood of hospitalization in high-risk COVID-19 + outpatients, suggesting a safe and over the counter measure with potentially vital public health impact.
The reduction from 11 to 1.3% as of November 2021 would have corresponded in absolute terms to over 1,000,000 fewer older Americans requiring admission. If confirmed in other studies, the potential reduction in morbidity and mortality worldwide could be profound."Senior study author Dr. Richard Schwartz noted, "We found an 8.5-fold reduction in hospitalizations and no fatalities compared to our controls. Both of those are pretty significant endpoints."10 In addition to the featured study, other research also supports the use of nasal irrigation as a "useful add-on to first-line interventions for COVID-19."11
Nasal Wash Findings Render COVID Response UselessDr. Amy Baxter, featured study author and emergency medicine physician at the Medical College of Georgia at Augusta University, said she got inspiration for the study from visits to Southeast Asia, where nasal irrigation is used daily as part of personal hygiene. She explained:12
"What we say in the emergency room and surgery is the solution to pollution is dilution … If you have a contaminant, the more you flush it out, the better you are able to get rid of dirt, viruses, and anything else … One of our thoughts was: If we can rinse out some of the virus within 24 hours of them testing positive, then maybe we can lower the severity of that whole trajectory."That indeed turned out to be the case, a finding that should not come entirely as a surprise. In 2019, researchers with Khon Kaen University in Thailand similarly found that nasal irrigation was an effective treatment for nasal disease, helping to clear nasal secretion, improve nasal congestion and improve sinus pain, headache, taste and smell, and even sleep quality.13
"All the pandemic mitigations were unnecessary. Simply telling newly infected people to rinse their nose with a saline rinse if they got sick would have reduced the hospitalization rates to levels comparable to the flu. The CDC is still not telling people to do this today even though there is no risk to anyone …
This would apply to any other virus or bacteria as well, based on the mechanism of action. It's also extremely safe … This treatment is still being ignored by every mainstream medical institution … Universities should mandate students do nasal washes after getting COVID instead of taking vaccines."
Mouth and Nose Spray Shields Against COVID-19Nasal irrigation is just one tool to help protect against COVID-19. A simple mouth and nose spray containing povidone iodine (PVP-I), a microbicidal agent with a virucidal efficacy of 99.99%,15 could also act as an effective shield to protect against COVID-19.
In this case, the spray formulation was particularly effective because it allowed the active ingredient to diffuse further and reach deeper into the nose and nasopharynx, which is the upper part of the throat behind the nose. The oro-nasal spray acts as a protective layer, coating the nasal and oral mucosa.
Typically, if you're exposed to SARS-CoV-2, it will enter your body through your nose and mouth, remaining there for a time before binding with ACE2 receptors and entering cells. Once inside your cells, the virus has an opportunity to multiply.
Nebulized Hydrogen Peroxide for Respiratory Infections
Remember, the study above shows simple saline nebulization is useful. You don't need much peroxide to enhance the effect of the saline. The video above goes into great detail on how to prepare and implement the hydrogen peroxide solution and how to use the nebulizer.
The KEY here is to have the nebulizer and peroxide solution locked and loaded. You need to have it in your home BEFORE you get sick. Waiting several days to obtain it, if you even can, could radically reduce its effectiveness.
Since early treatment is vital, ideally on day one, you want to have the nebulizer and materials already in your house ready to go. I would avoid using a battery powered hand held nebulizer and rather opt for a unit you plug into the wall.
I've embraced nebulized peroxide since the COVID-19 pandemic broke out and have received many anecdotal reports from people who have successfully used it, even at more advanced stages. Dr. David Brownstein also successfully treated hundreds of COVID-19 patients using immune-boosting strategies such as intravenous or nebulized hydrogen peroxide, iodine, oral vitamins A, C and D, and intramuscular ozone.
Tips for Effective Nasal IrrigationTraditionally, slightly warm saline water — a solution of 2.5 grams of salt in 500 milliliters of water — is recommended for nasal irrigation.21 For additional antimicrobial action, povidone iodine (0.5% to 1%) can be added to the saline solution.
