Subject: Earplugs for OWS? I came across the QA below in a FAQ on the website of a commercial SF bay focused swim group. Granted, one of the sponsor's of that site is Mack's so I have to be skeptical, but how necessary if at all are earplugs for OWS (and in particular in the SF bay )? I do understand a little bit about the 7th cranial nerve and the inner ear from my swim days. What about the bacteria issue? Or is all of this just a shill to sell more of their sponsor's goods?
Q: Why do I need earplugs?
A: ALWAYS wear earplugs-- and "Mack’s" are the best. If the inner ear gets cold, it affects your equilibrium and you may become dizzy after leaving the water. Earplugs also help keep your head warm and protect you from bacteria in the water.
