Tobacco leads to hearing loss?

The relationship Between Tobacco and Hearing

The toxicity of the nicotine in cigarettes directly affects the ear (hearing).


It's been said that cigarettes can do 'a lot of harm and a lot of good', but did you know that they also affect your ears (hearing)?

With the revised Health and Wellness Act going into full effect in April 2020, tobacco smoking has been banned indoors as a general rule, and the number of smokers has been decreasing every year.

Although many people are already aware of the dangers of smoking, it has been reported that tobacco, which causes various diseases such as cancer, heart attack and periodontal disease, is actually related to "hearing loss."

The Relationship Between Tobacco and Hearing

So what is it about cigarettes that affects "hearing loss"?

There are two main medical factors that have been identified

  1. The toxicity of nicotine directly affects the ear (hearing)
  2. Smoking increases carboxyhemoglobin/increased blood viscosity and
    The ear (hearing) is affected when the cochlea (the hair cells that sense sound) in the inner ear are ischemic.


In addition, the National Center for Global Health and Medicine reports that smokers have a 60 percent higher risk of hearing loss than non-smokers.

The study followed 50,195 Japanese people aged 20 to 64 years old for up to eight years to determine the relationship between their smoking status and their ear (hearing), and clearly stated the risk of smoking.

  • The more you smoke, the higher the risk of hearing loss.
  • Smokers who smoke 21 or more cigarettes a day have a 60% higher risk of high frequency hearing loss


These risks are not only for cigarettes, but also for heated cigarettes (IQOS, glo, etc.) that contain nicotine.

It's not too late! Hearing care!

It's never too late to quit smoking.
The study reports that after five years of smoking cessation, the risk of hearing loss is the same as for non-smokers.

The study reports that after five years of smoking cessation, the risk of hearing loss is the same as for non-smokers.
This may sound like a bit of a preaching to the choir, but if you're having trouble quitting smoking, why not start by reducing the number of cigarettes you smoke and the amount of nicotine you consume?

Summary (Author's Thoughts)

To be honest, when I learned of this fact, I wondered whether or not to write about it, because there are some people who love smoking.
On the other hand,when I thought about the "impact of hearing loss on dementia," it was a fact that I would like people to know.


I myself am a non-smoker, but there are still many smokers among my generation and older people.
The ear (hearing) is a function that declines with age, just like strength and vision, but it can be taken care of.

I hope that this article will reach as many people as possible and help them become aware of the risks of hearing loss.
