Hearing Health and Sleep Health

If you have sleep apnea, you may want to schedule an appointment to see your hearing care professional, too. A research study of nearly 14,000 people found that hearing impairment was more common among those who had a higher body mass index, snored and had severe sleep apnea. Study participants received in-home sleep apnea studies and on-site audiometric testing. Another, much smaller study found that among people with severe obstructive sleep apnea, those with the lowest oxygen levels were much more likely to have hearing impairment.

What is sleep apnea?

There are several types, but the most common is obstructive sleep apnea (OSA). This type of sleep apnea arises when the muscles and tissues around a person’s airway relax and block breathing. This causes a person to snore and frequently wake up, out of breath. Sleep apnea should be treated, since it not only leads to exhaustion, it strains the heart and increases the risk of heart disease.

How does sleep apnea affect hearing loss?

It’s not known for sure if sleep apnea directly causes hearing loss, but it certainly reduced blood flow to the ears. This causes problems in translating sounds from your cochlea to the brain. Your ear hair is very sensitive, so loud snoring over many years can permanently damage them, causing sensorineural hearing loss.

In addition to increasing your risk of many different types of health disorders, both hearing loss and sleep apnea can have a profoundly negative impact on your personal relationships. Bed partners are often the first to realize a person has sleep apnea, and the snoring and restlessness causes them to lose plenty of sleep, too. Add hearing loss to the mix, and you have a recipe for lots of frustration and poor communication.

Hearing health professionals have known for some time that circulatory issues can cause hearing loss. Research indicates those with heart disease are more than 50% more likely to have some type of hearing impairment. According to the American Diabetes Association, patients with diabetes are twice as likely to have hearing loss as those who do not. Smokers are more likely to develop hearing loss because the habit depletes oxygen levels in the inner ear. Untreated high blood pressure can also contribute to hearing loss as well as tinnitus, which is also known as ringing in the ears.

What about tinnitus and sleep apnea?

It’s well known that tinnitus, or ringing in the ears, can make it hard to sleep and trigger insomnia. But what about its relationship to sleep apnea? There hasn’t been a lot of research on sleep apnea and hearing loss in general—and even less so when it comes to tinnitus. However, a 2017 case-control study in Taiwan did specifically look at the issue and found that “the risk of tinnitus was found to be significantly higher” in middle-aged and older people “with sleep disturbances, especially with sleep apnea.” It’s not known if one causes the other, or if other factors, such as genetics or lifestyle choices, increase a person’s risk for both disorders. We do know that treating sleep apnea increases the chance of a good night’s sleep, thereby reducing exhaustion and stress in a person’s life—which is always a good thing for tinnitus sufferers.
