Nasal rinsing has become a trusted ritual for many seeking relief from congestion, allergies, and sinus discomfort. However, health authorities are once again reminding the public that how you rinse matters just as much as what you rinse with.
Recent advisories highlight a rare but serious risk:
Using untreated tap water in neti pots or nasal irrigation devices can introduce harmful microorganisms, including Naegleria fowleri - a “brain-eating” amoeba that can enter the body through the nasal cavity. While infections are extremely rare, they are often fatal.
To ensure safe sinus care, always use:
- Distilled or sterile water (store-bought or boiled for at least one minute and cooled),
- Properly cleaned devices, and
- Hygienic handling practices between uses.
Nasal irrigation remains a highly effective method for improving airway health when done correctly. Education around safe technique is essential in transforming a simple wellness habit into a clinically sound practice.
