It's official, Harvard Medical School put out a newsletter this month suggesting that nasal irrigation is the "first line of defense" for sinus problem. So all my friends that thought I was weird and disgusting were wro... okay, maybe they were right but at least they can't say I wasn't practical.
Anyways, here's a link to the article that Harvard Medical school put out about "What to do about sinusitis". It's also got a really nice diagram of the head showing and explaining the different sinuses.

Happy nasal irrigating!
