Nyet to Neti Pots

When the hay fever gets intense and when the pills and inhalers don't provide relief, allergy sufferers can rinse their nasal passages with saline solution. However, the appliance of choice, the neti pot, now comes with a warning from the CDC: [bold added]

Neti pots are one of the better known tools of nasal rinsing. They look like small teapots with long spouts, and usually are made of ceramic or plastic.

Users fill them with a saline solution, then pour the liquid in one nostril. It comes out the other, draining the nasal passage of allergens and other bothersome contaminants...

More than a decade ago, health officials linked U.S. deaths from a brain-eating amoeba — named Naegleria fowleri — to nasal rinsing. More recently, they started to note nasal rinsing as a common theme in illnesses caused by another microscopic parasite, Acanthamoeba.

Acanthamoeba causes different kinds of illness but is still dangerous, with a 85% fatality rate in reported cases...

This amoeba can be found naturally all over the environment — in lakes, rivers, seawater and soil.

It can cause diseases of the skin and sinuses, and can infect the brain, where it can cause a deadly form of inflammation. The microorganism also has been connected to non-fatal, but sight-threatening, eye infections, sometimes through contaminated contact lens solution.

U.S. health officials have identified about 180 infections from the single-cell organism since the first one was diagnosed in 1956.

In the vast majority of cases, researcher don’t know exactly how people became infected. But in reviewing cases in recent decades, CDC researchers increasingly received information that a number of the cases had done nasal rinsing, Haston said.

Research also has indicated it’s common in tap water. A study done in Ohio in the 1990s found more than half of tap water samples studied contained the amoeba and similar microorganisms.

I use a neti pot occasionally, and warm tap water brings relief when nasal passages are swollen. However, I'm going to switch to distilled or pre-boiled water. I've lost enough brain cells already.
