Your Hearing Isn’t an Island

There’s a tendency in this era of specialization to see the functions of the body as operating in isolation. Maybe even more so hearing loss, since it is treated with very specialized and high-tech devices like hearing aids.

But recent studies make it pretty clear that overall physical health is good for your hearing — and may even put off the need for a hearing aid at all.

Studies have shown that hearing health, especially in people over age 50, is markedly better when that person’s cardiovascular health is better. In fact, data shows that people over 50 who are in good shape are likely to still have a level of hearing commonly found in people in their 30s.

The reason is that a healthy cardiovascular system will include greater blood flow to a person’s head. And healthy blood flow is crucial to the functioning of the inner ear, especially the fine hairs that are part of the cochlea, the contact point where sound waves are translated into what humans hear.

And although the term “cardiovascular health” may bring up images of gym workouts, what is required isn’t too daunting. The benchmark is large muscle movement, the kind that takes place in activities such as walking, cycling, and swimming. The time commitment to that kind of exercise is for 20 to 30 minutes, 5 days a week.

Even with busy modern lives, that’s not too much of a commitment. Especially since the benefits of maintaining a healthy circulatory system are so far-reaching, including deep into the inner ear.
