Yes, smoking can contribute to hearing loss as it affects various parts of the ear. Read below to find out how.
How does cigarette smoke affect the inner ear?
Nicotine and carbon monoxide found in cigarette smoke can cause hearing damage. This occurs when harmful chemicals affect the structures of the inner ear and can cause sensorineural hearing loss.
The Cochlea
The cochlea in the inner ear is home to thousands of tiny hair cells that are vital for hearing. The health of these hair cells depends on good blood flow to the cells. These chemicals in cigarette smoke reduce the amount of oxygen in the blood vessels of the cochlea and narrow the blood vessels in the cochlea. Without this supply of oxygen, the hair cells are damaged. Hair cells cannot generate electrical impulses that affect hearing.
The auditory nerve
The auditory nerve (auditory nerve) in the inner ear is responsible for transmitting information (electrical impulses) from the cochlea to the brain, where the sound is located. The auditory nerve uses neurotransmitters to send this information. The chemicals in cigarette smoke have a negative influence on the function of the "messenger substances". This means that the auditory nerve cannot send effective electrical impulses to the brain, which affects hearing.
Another Reason To Quit Smoking
Damage to the hair cells in the inner ear is irreversible, and therefore hearing loss due to hair cell damage is permanent. It is important to reduce your exposure to cigarette smoke, including secondhand smoke, to reduce the risk of further damage to your hearing. If you're concerned that your habit has already damaged your hearing, call your hearing care professional today for a hearing exam.
