There is a really short path between your nasal cavities and your brain which makes it relatively easy for infections to pass from the nasal cavity into the brain. The last thing you want is for microbes from tap water getting into your brain. Treating brain infections is really hard due to the blood-brain barrier potentially blocking antibiotics from reaching the brain and swelling of the brain due to white blood cells flooding the area as your immune system reacts to the infection is really bad because there is not much room in the skull cavity for your brain to swell.
Meningitis is the infection and inflammation of the fluid and membranes surrounding the brain and spinal cord and even if you survive it it can have serious long lasting side effects like brain damage and months of physical therapy.
