Does Smoking Affect Hearing?

Smoking is well-known for its harmful effects on lung health, heart health, and overall well-being, but did you know it can also impact your hearing? Lung cancer is a well-documented health risk associated with smoking, providing a broader context for the discussion on hearing loss. Research has shown a surprising connection between smoking and hearing loss, raising important questions about how this habit affects your auditory system.

In this article, we answer common questions and find out how and why smoking affects yours hearing, including information on the dangers of passive smoke exposure, and if vaping is really a safer option like its being advertised. 

What Happens When You Smoke a Cigarette?

According to cancer research UK each puff of a tobacco smoke introduces over 5,000 chemicals into your body. These chemicals, including tar, nicotine, and carbon monoxide, reduce oxygen levels in the blood and restrict its flow in vessels going to critical areas of the body, including the inner ear.

​This area relies on a steady supply of oxygen-rich blood to maintain its delicate structures and functions. When this blood flow is compromised, it can damage the tiny hair cells in the cochlea, which are essential for transmitting sound signals to the brain. Unfortunately, once these hair cells are damaged, they cannot regenerate, leading to permanent hearing loss.

​The Surprising Link Between Smoking and Hearing Loss

​Studies have found that smokers are up to 70% more likely to experience hearing loss than non-smokers. While all smokers are at an increased risk, the risk is notably higher for heavier smokers in comparison to lighter smokers. This increased risk that smoking triggers applies to both high-frequency and low-frequency hearing loss.
​
High-frequency hearing loss affects your ability to hear higher-pitched sounds, such as birds chirping or the voices of children, while low-frequency hearing loss makes it harder to detect deeper sounds, like a drumbeat or a person’s voice in a crowded room. The exact mechanisms are still being studied, but it’s clear that smoking’s impact on blood flow and overall health plays a significant role.

How Smoking Impacts Your Hearing Health

The harmful chemicals in tobacco smoke not only affect blood pressure but also contribute to inflammation and oxidative stress, both of which can cause major problems like coronary heart disease as well as harm auditory nerves and other critical parts of the hearing system. Certain components in the inner ear play a crucial role in translating sound vibrations into electrical impulses, which are essential for hearing. Smokers are also more prone to ear infections, which can further exacerbate hearing issues. Smoking long-term weakens the immune system, making it harder for your body to fight off infections that may damage your ears.

Can Passive Smoke Cause Hearing Problems?

Yes, unfortunanlty passive smoking or secondhand smoke can also contribute to health problems and hearing impairment, for this reason smoking was banned in pubs in England on July 1st 2007.  

Children exposed to passive smoke are particularly vulnerable, as their auditory systems are still fragile and to susceptible to develop health problems which could lead to hearing damage. Research has shown that children living in households with smokers are more likely to experience hearing problems later in life. Non smokers beware! adults exposed to secondhand smoke are also at risk, breathing in the chemicals in tobacco smoke can harm the inner ear, middle ear and auditory nerves, even without direct smoking.

​Can Smoking Cause Tinnitus?

​Tinnitus, often described as a ringing, buzzing, or whooshing sound in the ears, has been linked to smoking. The restricted blood and nerve damage caused by smoking cigarettes can contribute to the development of tinnitus. Smokers are more likely to develop tinnitus symptoms than non-smokers, and smoking can worsen existing tinnitus by further damaging the auditory pathways. 

​Will Tinnitus Go Away If I Stop Smoking?
If tinnitus is caused or worsened by smoking, there is a possibility that the symptoms may improve or even resolve after quitting. Improvements in your sense of smell and taste occur shortly after quitting smoking, which can contribute to overall health improvements. The body begins to repair itself when you quit smoking, and blood flow to the inner ear may return to normal.

How Many Cigarettes Would Cause Tinnitus?
​There is no precise number of cigarettes or years smoking that directly causes tinnitus, as susceptibility to the condition varies from person to person. However, the more a person smokes, the greater the risk of developing tinnitus, frequent ear infections or exacerbating existing symptoms. As we mentioned even light smoking or exposure to secondhand smoke can contribute to tinnitus, especially if there is a history of hearing problems or other related health conditions. The toxic substances in cigarette smoke can accumulate in the body over time, making the likelihood of hearing damage and tinnitus higher with prolonged smoking.

Can Smoking Cause Ear Infections to The Inner Ear?
​Cigarette smoke contain harmful substances such as carbon monoxide and nicotine which weakens the immune system and irritates the respiratory system. The Eustachian tube, which connects the middle ear to the throat, can become inflamed due to cigarette smoke exposure, creating an environment where infections can thrive. Chronic ear infections can lead to long-term hearing impairment if left untreated.
​

Is Vaping Safer Than Cigarette Smoke?

While vaping is often marketed as a safer alternative to smoking, it is not without risks. E-cigarettes contain nicotine and other toxic chemicals that can still harm blood circulation and contribute to oxidative stress, potentially affecting hearing health, in the UK the amount of teens exposed to vapes is rising with 18% of all teens aged 11-17 using vapes at least once during 2024.

Preliminary studies suggest that vaping (electronic cigarettes) may also increase the risk of tinnitus and other auditory infections which can lead to hearing loss in the same way as cigarettes can, though more research is needed to confirm these findings. If you’re using vaping as a way to quit smoking, it’s essential to consider your potential to still develop health problems and potential hearing issues even though vaping is portrayed as a reduced risk when compared to cigarettes.

Can Your Hearing Improve After Quitting Smoking?

Quitting smoking is one of the most important steps you can take to protect your hearing and overall health. While some damage to the auditory system, such as the loss of cochlear hair cells, is permanent, quitting smoking can prevent further deterioration and improve your auditory health in several ways. Studies suggest that quitting smoking can enhance blood circulation, which is critical for maintaining the health of the inner ear. Over time, improved oxygen levels in the bloodstream can help repair some of the inflammation and damage caused by smoking.

For most people, quitting before the age of 35 enables the body to largely recover from the harms of smoking, with life expectancy remaining similar to those that do not smoke, although this depends on how much you were smoking and your general health condition.

The Importance of Hearing Tests

Hearing tests are a crucial step in maintaining good hearing health. Regular tests can help detect hearing loss early, allowing for prompt treatment and prevention of further damage. If you’re a smoker, it’s essential to get your hearing checked regularly, as smoking increases the risk of hearing loss. A test can help identify any potential issues, and your healthcare professional can provide guidance on how to protect your hearing. Book a hearing test with us today!

Conclusion

Smoking tobacco and even passive smoke or vaping can significantly impact your hearing health. From increasing the risk of hearing loss and tinnitus to causing or prolonging ear infections, the effects of smoking on your hearing extend far beyond what many people realise.
​
Protecting your hearing is just one more reason to quit smoking and avoid exposure to passive smoke. By taking steps to quit today, plus monitoring your health with regular hearing tests you’ll be safeguarding not only your overall well-being but also your ability to enjoy the sounds of life for years to come.
