Nasal irrigation is a thing, a good thing. I usually get severe sinus infections. Last time I asked the doc how to avoid them. I was told to do a nasal irrigation (neti pot, etc. ...) once a week.
Guess what, over three years of weekly nasal irrigation and no sinus infections at all for me. I must stress that one should use only distilled water (tap water is no bueno).
And during allergy season (March through October), I’ll do it more frequently as needed.
It is like a power wash to get the boogies and other cruft out of one’s nasal cavity.
Never thought I’d mention nasal irrigation and boogies on a hunting forum, but yet here I am.
