Sometimes too much, sometimes probably not enough. Ear infections are pretty common for swimmers, but I made a point of shaking water out of my ears whenever I got out of the pool and swabbing them dry after practice, and I never had any problems. Some people use earplugs, and I guess caps might offer protection for some people (in my experience they didn't keep water out for long.)
