Drinking coffee may be good for your hearing, a new study suggests. Women who consumed higher amounts of caffeine were found to be less likely to have tinnitus, which is a steady ringing or buzzing in the ears.
The research included more than 65,000 American women aged 30-44, who did not have tinnitus in 1991 and were followed for 18 years. Women who consumed less than 150 mg of caffeine per day (about 1.5 cups of coffee) were 15% more likely to develop tinnitus than those who consumed 450-600 mg daily. Most of the caffeine consumed came from coffee, according to the study published in the August issue of The American Journal of Medicine.
While the exact reason why caffeine seems to have this effect is unknown, it is known that it stimulates the central nervous system and has had a direct effect on the inner ears of animals in previous studies.
