I use a version* of a net-pot to flush out my sinuses after surfing. If I don't, especially if I surf in a red tide, I get a nasty sinus infection (surfers sinusitis or acute sinusitis). I even had sinus surgery to reduce my turbinates and increase my sinus ducts which helps, but still doesn't prevent the problem. * I use NeilMed's sinus flush which basically is a sealed bottle with a straw I can use to force flush my sinuses, vs. just using gravity.
