Tinnitus, otherwise known as ringing in your ears, plagues about one in five people. Yes, it’s annoying. Now comes a study suggesting that a cure for tinnitus is so simple that it too is annoying: coffee. HealthDay reports that researchers at the Harvard Medical School followed 65,000 aged 30 to 44 who did not have tinnitus, for 18 years. The researchers found that women who drank less than 150 milligrams a day of caffeine (found in about one-and-a-half 8-ounce cups of coffee) were 15 percent more likely to develop tinnitus than those who consumed 450 mg to 599 mg a day of caffeine. What’s up with that? The short answer is: more research is needed.
