How to Prevent Swimmer’s Ear

In the perfect world, swimmer’ ear would be a large muscular appendage on either side of the head and capable of propelling its owner through water at a hight rate of speed. In the real world, alas, it is an ear infection, often caused when more water enters the ear canal than leaves the ear canal. Geezer knows it well.
Now comes the Boston Globe’s health answer person, Judy Foreman, with some advice about how to prevent swimmer’s ear. 
One way to prevent "swimmer’s ear," Foreman says, is to use earplugs to keep
water out. You can also rinse your ears after swimming with white
vinegar, alcohol, or a half-and-half solution you can make at home. And
you can also buy over-the-counter products such as Swim Ear (mostly
alcohol) or prescription acetic acid drops for use after swimming.  Foreman warns that if you do get swimmer’s ear, see
your doctor, who will likely prescribe antibiotic drops.
