The negative effects of drinking too much are pretty well advertised. Less obvious is that drinking too much over both the short-term and long-term can also cause hearing issues.
Believe it or not, too much alcohol in the bloodstream can cause stress on the tiny hairs inside the ears that send electronic signals to the brain. One of the reasons hearing loss is common in many older people is because these hairs stop regenerating. And alcohol can cause the same kind of damage.
On the other hand, this one is not so hard to believe — alcohol affects the brain. This includes the auditory cortex, where the sound transmitted from the ears is processed. Long-term drinking can shrink the auditory cortex.
Temporary or permanent tinnitus — an incessant ringing in the ears — can also result from alcohol consumption. This is due to the increased blood flow that drinking causes, which throws the inner ear mechanism awry. And since that blood is full of alcohol, the fluid within the ear that is an important part of its functioning is infused with alcohol. This has a number of repercussions, including altering one’s sense of balance — which is why the room starts to spin and “falling down drunk” is a thing.
And there’s a term for getting oblivious about how loud an environment is. It’s called “cocktail deafness.” Getting drunk at a concert or in a loud bar can result in basically forgetting to process how loud it really is. This leads to one of the worst things for hearing health — prolonged exposure to high-decibel sound that can do permanent damage.
Hearing health, another reason to be mindful of your alcohol consumption.
