I know it seems crazy if you haven't tried it. It looks like it must hurt or feel like drowning... but it doesn't. It doesn't at all actually. It feels good to gently help whatever is irritating your sinuses to move on it's way out. It is a great help for allergies as well. The stream of salty water keeps things moving so your body doesn't have to work so hard to keep it's pathways clear.
Personally, I like the plastic squirt bottle version made by NeilMed. I was going to put a link to the product but here's a video about it... they are so much better than pictures, and I think it's funny to see people do this so calmly. I like the squirt bottle better as I feel less awkward pouring water through my face this way... personal preference. And one more note, I know in both of these videos they are selling you their product, which you do not need to buy to achieve this treatment. The salt water mixture is simply 1 teaspoon non-iodized salt to 16 ounces water, and if you feel comfortable trying it, you can sniff it... although to me that seems scary, for now, I'll stick to the squirt bottle method. Here's the other video, enjoy and hope you're well xxtbone
