How Insomnia Affects Your Hearing
We all know that sleep is crucial to
our physical health and mental wellbeing, giving body and mind the chance to
rest and recharge. And we all know how it feels when you don’t get a good
night’s rest – sluggish, exhausted, and just out of it. Those with insomnia may
feel this every day—and face a higher risk of developing side effects like
depression, heart disease, high blood pressure, stroke, diabetes, and obesity.
Insomnia can also be detrimental to your hearing health, leading to hearing
loss and worsening tinnitus symptoms.
Poor
cardiovascular health
Perhaps the biggest link between
lack of sleep and diminished hearing is the effect of insomnia on the
cardiovascular system. Insufficient sleep is known to cause poor blood circulation
throughout the body, including your ears. Since the tiny hair cells in the ear
that detect sound waves and translate them to the brain depend on strong blood
flow to function properly, any cardiovascular issues can damage these fragile
cells and cause hearing loss.
Connection
to sleep apnea
Another factor could be sleep apnea.
About 43 percent of people with insomnia also have sleep apnea, which causes
patients breathing issues that often wake them up repeatedly throughout the
night. Since studies have revealed that people with sleep apnea often have
larger amounts of plaque in their blood vessels, the condition might further
constrict blood flow to the hair cells and damage hearing.
Effects
on tinnitus sufferers
Hearing loss isn’t the only way
insomnia can affect your hearing health—it can also worsen the symptoms of
tinnitus, or the phantom ringing, buzzing, humming, or whistling some people
experience. One study found that insomnia can have a negative effect on those
with tinnitus, increasing the perceived severity of
tinnitus, decreasing their tolerance of the condition, and worsening
its functional and emotional toll. It can often be a vicious cycle, as focusing
on the tinnitus can make it difficult to fall asleep, and lack of sleep makes
tinnitus seem much worse.
Just as with hearing loss, the
longer you put off seeking treatment for insomnia, the more drastic its effects
can be. That’s why it’s important to talk to a doctor about your insomnia
and what you can do to get a better night’s sleep. And if you already have hearing
loss or tinnitus, schedule an appointment with a hearing care professional to find the best course
of treatment.
