Studies have shown that good circulation plays a role in maintaining good hearing health. Conversely, inadequate blood flow and trauma to the blood vessels of the inner ear can contribute to hearing loss.
That is because the delicate hair cells in the cochlea, which play an important role in translating the noise your ears collect into electrical impulses for the brain to interpret as recognizable sound, rely on good circulation. Poor circulation robs these hair cells of adequate oxygen, causing damage or destruction. Because these hair cells do not regenerate, it results in permanent hearing loss..
Research has been published that was conducted over 60 years on cardiovascular health and its influence on hearing health. Their findings confirm that impaired cardiovascular health negatively affects both the peripheral and central auditory system, especially in older adults.
Charles E. Bishop, AuD, Assistant Professor in the University of Mississippi Medical Center's Department of Otolaryngology states that
"Hearing health should not be assessed in a vacuum," said Bishop. "There is simply too much evidence that hearing loss is related to cardiovascular disease and other health conditions. It's time we maximized the information we have in order to benefit the individual's overall well-being."

Hearing loss is a common problem caused by aging, disease, heredity, and noise exposure.
Hearing loss is about twice as common in adults with diabetes compared to those who do not have the disease, according to a new study funded by the National Institutes of Health (NIH).
Researchers have discovered that the higher rate of hearing loss in those with diabetes after analyzing the results of hearing tests given to a nationally representative sample of adults. The link between diabetes and hearing loss was evident across all frequencies, with a stronger association in the high frequency range.
Adults with pre-diabetes, whose blood glucose is higher than normal but not high enough for a diabetes diagnosis, had a 30 percent higher rate of hearing loss compared to those with normal blood sugar tested after an overnight fast.
The study, published early online June 17, 2008, in the Annals of Internal Medicine, was conducted by researchers from the NIDDK, the National Institute on Deafness and Other Communication Disorders (NIDCD), components of the NIH, and Social & Scientific Systems, Inc., which provides support on public health topics to NIH and other government agencies.
Diabetes may lead to hearing loss by damaging the nerves and blood vessels of the inner ear, the researchers suggest. Autopsy studies of diabetes patients have shown evidence of such damage.
"Hearing loss may be an under-recognized complication of diabetes. As diabetes becomes more common, the disease may become a more significant contributor to hearing loss," said senior author Catherine Cowie, Ph.D., of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), who suggested that people with diabetes should consider having their hearing tested. "Our study found a strong and consistent link between hearing impairment and diabetes using a number of different outcomes."
