Of all the deadly consequences the body suffers from smoking, hearing loss is not one that is frequently discussed. While most of the focus is on the damage smoking can do to the heart and lungs, hearing loss is certainly something that will result from prolonged smoking. The nicotine in cigarettes causes the restriction of blood vessels, which is why many people who smoke for years suffer heart attacks. The sensory organ of the ear is the cochlea, which needs a constant flow of blood from a specific blood vessel in order to function properly. When you smoke on a regular basis, you restrict blood flow to the cochlea and deprive this organ of much needed oxygen. The small capillaries that bring blood to the ear become damaged, and hearing loss results. Each time you smoke a cigarette, the blood flow to the inner ear is slowly being reduced.
4. Working on the Job
Chances are that you are so accustomed to the sounds around your workplace that you don’t even realize they are doing damage to your hearing. This phenomenon is like the person who moves into a house along the railroad tracks. The first few weeks are brutal, as they struggle to fall asleep because of the loud noise every night. After a few months, however, they become so used to the noise that they need it to sleep, and many times after they move they have difficulty when it is too quiet because they are so used to the noises. Toxic noises at your job could be injuring the cochlea and slowly leading to hearing loss. Many construction workers, musicians, firemen, and factory workers are at a much higher risk to extended exposure to these loud noises. Being exposed to constant sounds of 70-90 decibels will slowly decrease the quality of your hearing permanently. These loud noises damage the fragile hair cells inside the cochlea, which instead of bending to sounds now violently snap and break off.
