Their research findings show that tinnitus, that awful persistent ringing, chirping or hissing in the ears, may be reduced by caffeine, a stimulant most often associated with coffee. The rate of tinnitus was 15 percent lower among participants who consumed between four and six cups of coffee compared with those who drank a cup and a half each day. The study followed over 65,000 women over 18 years and asked them to self-report their lifestyle, caffeine consumption and medical history.
Although researchers from Boston have not found enough evidence to explain the results, previous studies indicate that caffeine’s stimulant effects on the nervous system also benefit the inner ear. Approximately one in six adults suffer from tinnitus, which may stem from an underlying condition, such as an ear injury, excessive noise exposure or hearing loss.
