(BWH), women with a higher intake of caffeine had a lower
incidence of unexplained ear ringing.
For the study, the researchers followed more than 65,000
women. They tracked self-reported results regarding lifestyle and medical
history from these women, aged 30 to 44 years and without tinnitus in 1991.
After 18 years of follow up, researchers found 5,289 cases of reported incident
Gary Curhan, a physician-researcher at the Channing Division of Network
Medicine at BWH
in Boston, Massachusetts, said that they observed a
significant inverse relation between caffeine intake and the incidence of
tinnitus among those women.
Significantly, researchers discovered that when compared with women with
caffeine intake less than 150 milligrams/day (one and a half 8-ounce cups of
coffee), the incidence of reported tinnitus was 15 percent lower among those
women who consumed 450 to 599 mg/day of caffeine.
Researchers noted that the majority of caffeine consumed among the women was
from coffee and the results did not vary by age. "We know that caffeine fuels
the central nervous system and previous research has demonstrated that caffeine
has a direct effect on the inner ear in both bench science and animal studies,"
Researchers said that further proof is needed to make any recommendations
about whether the addition of caffeine would improve tinnitus symptoms.
The research was published in the journal American
Journal of Medicine
