Help! My Nasal Rinse Caused a Brain-Eating Amoeba!

    Picture this; You're busy fighting an illness. Your limbs have never felt so sore and every cough feels like sandpaper against your dry throat. Worse of all, it's been four days of this non-stop agony! Today's poison of choice -- your sinuses feel ready to explode. Every sniffle and snort only makes the pressure worse, which doesn't help your intense study session for that test tomorrow. But, your Google searches bring you to a supposed cure-all. You know you have it, so you run upstairs and fill a nasal rinse with tap water. What's the worst it could do?

Little do you know, you have introduced a brain-eating microscopic organism into your head...

Naegleria fowleri, or the "brain-eating amoeba" as it is commonly known, gets access to your brain via the olfactory nerve and easily makes its way through the thin bone plate called the cribriform plate into your nervous system. Here it begins to rapidly eat away at that squishy yet important blob in your head and causes issues like headaches, loss of balance before reaching coma and, soon, death with a 98% mortality rate as the worlds deadliest parasitic infection (Indolfi et al., 2025). 

                                                      

    So... a little scary, right? Well, at least the solution is relatively easy for the average American household. Most of our systems contain adequate chlorine to kill it. But its better to be safe rather than sorry, so anyone dying to try a nasal rinse such as the Neti Pot should also boil water for at least a minute before using it, or filter it using a filter designed for small organisms should do the trick (Indolfi et al., 2025). 

    The next time your sinuses give you the pain we all dread, or you feel that your nose just needs a little rinse, don't forget about the dangers lurking in our water.
