Or is that just a guess?&lt;p&gt;It could possibly and simply be the fact you swam every day. A few years ago I bought my first house with a pool and have had a pool since. I swam every day for a couple years (~8 months&amp;#x2F;year), then this year I&amp;#x27;m having a ton of swimmer&amp;#x27;s ear &amp;amp; sinusitis issues. My pool water is about as clean as it gets for outdoor swimming. And for me at least has been more correlated with frequency of contact with water than anything else. If my ears or sinuses act up, I take a week off from the pool and it gets better.</text><parent_chain><item><author>consumer451</author><text>This rule applies to any water near land. You get runoff from dog, cat, bird defecation among whatever chemicals may be found on land. This is even if storm water sewage does not overflow.&lt;p&gt;I lived in Key West for half of my life. I got addicted to swimming daily and would always go, no matter what. Now I have sinusitis caused cluster headaches. When I trace back events, the first one happened about a year into the swimming. Now they are truly debilitating.&lt;p&gt;I would even add not swimming during an out-going tide if the water passes by nasty land. (nasty = like seemingly lovely mangroves where birds live or bird poo covered rocks)&lt;p&gt;Now I always check water quality reports to find the cleanest water on vacation as well.

It&amp;#x27;s one of those things that should be in a random stupid things not to do in your like rulebook that should exist.&lt;p&gt;I have a few of these rules, that I picked up at random points in my life that either saved my life later on or caused permanent damage because I was young and stupid and didn&amp;#x27;t bother listening to my elders experiences.</text><parent_chain><item><author>consumer451</author><text>This rule applies to any water near land.
