Tell me more about nasal sprays as protection against the coronavirus

I'm spending more time indoors and want more protection against the virus. A few years ago nasal sprays were claimed to be effective against the virus, either by creating a protective barrier or killing the virus. Was this hype and marketing or is it true? What's the sentiment on this forum?

Could I just make my own 0.5% povidone-iodine nasal spray?

The intended use would be to use the spray shortly before and after spending time indoors with other people, and when I notice that I'm sick. So it needs to be cheap and unproblematic with frequent use.

I'm also thinking about getting the Novavax vaccine.

I'm hoping that this will limit the risk of long covid and damage done to the body.

 

I believe this is true. I think even stuff like Vicks First Defence helps lessen the risk of infection. https://www.southampton.ac.uk/news/...ld-keep-colds-and-flu-at-bay-study-finds.page

 

We have a thread on this somewhere. Dr Bansal recommended me a specific type of nasal spray. I'll find the thread and add it as an edit.

Bear in mind, though, that if you're laughing, coughing, yawning, preparing to sneeze, or slightly out of breath, you will breathe in through your mouth. We probably do this more than we think.

That's how I got it (at least twice, possibly three times). There's a lot of craic and laughter and I also have to gulp air deep into my lungs in a split second while playing fast tunes, so I've no chance of dodging it.

 

I have no illusions about avoiding the virus entirely, but maybe I can avoid a portion of future infections and lessen the severity and risk of long covid.

 

See #3 which includes link to research study on this topic.

 

A couple of years ago I considered buying a saline nasal/sinus irrigator (Navage) that is often advertised on tv. A doctor advised to rinse only using filtered or sterilized water. Tap water is safe for drinking because our stomach acid kills any bacteria, but if you use tap water in a nasal rinse, the bacteria can continue to thrive and can cause infections, in rare cases, travel to the brain.

 

Yep, same reason people who wear hard contact lenses need to make sure no tap water ever splashes into their soaking solution.
