Five bad habits that lead to hearing loss

1. Listening to the MP3 music player for a long time

Young people wearing headphones and listening to MP3 are now almost always on the road and on the bus, which is an important cause of hearing loss in many young people. When listening to music for a long time with headphones, it will stimulate the distal end of the auditory nerve, causing abnormal hearing and nerves, which may cause hearing fatigue. In addition, the earphones are close to the eardrum, which can increase the sound signal much, and the long time will cause damage to the eardrum. Hearing damage, moderate to above will cause deafness. It has been reported that any sound above 90 decibels can cause a certain degree of hearing loss if the contact time is too long. Experts said, “MP3 plays mostly more than 100 decibels, and can even be as high as 120 decibels. This volume is almost equivalent to the noise of a jet plane taking off.”

2. Abuse of antibiotics

Hearing loss caused by drug poisoning has become one of the main causes of hearing loss in developing countries. The survey showed that many patients with deafness were caused by the abuse of antibiotics. There are many drugs that are easy to cause hearing loss of drug poisoning, including clinically used anti-inflammatory drugs, such as streptomycin, gentamicin, kanamycin, small noromycin, lincomycin, etc. belong to this category. In addition, there are some diuretics, chemotherapeutics and so on. It usually causes the drug poisoning to be absorbed through the intact skin and mucous membrane. Therefore, the poisoning pathway is mostly caused by injection, and reaches the inner ear through blood circulation, causing poisoning of the inner ear nerve receptor, causing deafness or dizziness. Among them, the most serious hearing damage should be led by aminoglycoside antibiotics. Therefore, these drugs should be given enough attention. Do not abuse drugs at random. If you must use them, you must use them under the guidance of a doctor. Modern research has shown that drug sensitivity may be family-inherited, so children of such patients should also pay attention to the hearing loss of drug poisoning.

3. Calling mobile phone for a long time

Although the radiation of the mobile phone is invisible, it causes great damage to the ear. According to the research, the wavelength of the electromagnetic wave emitted by the mobile phone is 900MHz-1800MHz. The mobile phone is closest to the ear during the call, and the radiation received by the ear is also the strongest. The longer the electromagnetic radiation, the louder the volume, the greater the harm to the ear. Especially for adolescents with growth and development. Electromagnetic wave radiation can cause short-term tinnitus, ear suffocation, memory loss, and can cause thermal reactions such as headache, cerebral blood supply disorder, burning of facial skin, and burning of the ear and ear around the skin, and can cause sleep-like methods. Change, elevated blood pressure, cognitive dysfunction, etc.

4. Improper cleaning of the ears

Improper digging of the ear can easily damage the skin of the external auditory canal and bring bacteria into the ear canal. The skin of the external auditory canal is very delicate, the connection with the perichondrium is very tight, the subcutaneous tissue is small, the blood circulation is poor, and improper force on the ear can cause damage and infection of the external auditory canal, resulting in inflammation, ulceration of the external auditory canal, and even affecting the mouth and eating. Some people have itchy ears, and the eardrum is a very thin film, so that it can easily damage the gluten or listen to small bones, causing perforation of the eardrum and affecting hearing. If there are large deafness in the ear, ask a professional otolaryngologist to take it out with a special tool. Do not handle it yourself.

5. Regular smoking

People who smoke are more likely to develop ear infections or have reduced hearing under the influence of loud noise than people who do not smoke. The survey shows that smokers are about three times more likely to have otitis media than non-smokers. In addition, the nicotine in the smoke enters the blood, causing the small blood vessels to sputum and increase the viscosity, and the micro-arteries supplied to the inner ear are hardened, which may cause insufficient blood supply to the inner ear, seriously affecting hearing, and may even directly cause deafness. At the same time, carbon monoxide poisoning caused by smoking can damage the spiral ganglion, vestibular ganglia and brainstem nucleus. These tissues are the key parts related to hearing.
