The New York Times has an article on what it calls a neti pot - what you use to irrigate your nose. It's certainly not called a neti pot here, but I don't know the word, so... I remembered that there was one among my late mother-in-law's things, and decided that it was time to try it out. I watched a YouTube video on how to do it -- only the person in the video used something called 'neti pot salt', while I used the salt that we have, which is iodised. Will I get cancer?
Anyway, it's done. I didn't like it -- the water ran out of my nose and down the side of my face, and when I bent over afterward and snorted as directed, it came out of my nose and my mouth, and it was pretty much like being in the ocean and getting seawater in your nose. My nose does feel clean and all, though, so maybe I'll try it again sometime.
This is our family neti pot (that's a very small flower):
