Just a reminder: don’t use tap water when you do your sinus rinse/flood. Whether you’re a firm believer in a daily rinse or keep it in your back pocket for when you’re ill, make sure you don’t use water from the tap in your sinuses.
Naegleria fowleri has now been found as far north as Minnesota—so our geographic understanding has changed. It survives in warm fresh water, but is thwarted by salt and chlorine. Early symptoms include headache, nausea, vomitting, and changes in taste and smell.
Since fowleri started appearing a few years ago, scientists have rushed to improve treatment and diagnosis. In a few years, it likely won’t be as scary.
For now, just stick to swimming in clean, well maintained pools. And for yor sinus rinses, use either purified water (this doesn’t include all bottled water—read the label!) or an antimicrobial liquid like colloidal silver.
If you go the colloidal silver route, we’ve collected everything you need into one handy kit. A sinus bulb, two bottles of MesoSilver, xylitol to make the pH nose comfortable, and 7 cups for 7 rinses. They’re great to have on hand for when you fall ill!
