I can't really know for sure because I've only gotten COVID once. Even with that in mind, they are low risk. It's not the first time I've tried nasal irrigation. It's given me relief every time I had performed it during the times I had a cold or even just a stuffy/runny nose. This goes way back to when I was a child. The supplements I take have a lot of data points as far as their benefits. If you Google these things individually: nasal irrigation, vitamin c/d and zinc and add filter "before:2020", you will see all the pre-COVID data points. I'm not just jumping into some fringe left COVID hipster trend.
