Heart disease is a top cause of death for both men and women. But did you also know that heart disease is linked to hearing loss? Researchers have discovered that a healthy cardiovascular system is healthy for the auditory system too.

According to the Centers for Disease Control (CDC), heart disease is the leading cause of death in both men and women, killing nearly 610,000 people every year in the United States.

Most heart disease is linked to blood vessel damage from high blood pressure (hypertension) and/or stiffened, narrowed arteries (arteriosclerosis) from high cholesterol. These problems can cause blockages, spasms or ruptures of both major or minor vessels, leading to chest pain, a heart attack or stroke. In other cases, disorders of the heart’s muscles, valves or rhythm lead to other types of heart disease, such as heart failure.

An alarming number of people don’t understand how serious the threat of heart disease is to them personally, or how closely intertwined it is with other health conditions, such as hearing health.

The connection between heart health and hearing loss

So what does your heart health have to do with your hearing? It’s all about blood flow. 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’s 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.

Moderate Physical Exercise May Help

Although sensorineural hearing loss is permanent, you may be able to help preserve your hearing by adopting a physician-approved fitness program which includes cardiovascular exercise.

A study by researchers at Miami University discovered a positive relationship between hearing acuity and cardiovascular exercise. The study followed 102 non-smoking volunteers ranging in age from 22-78, whose hearing was evaluated after riding a stationary bicycle. Researchers concluded those with higher cardiovascular fitness levels had better hearing, especially among those age 50 and older.
