What are the dangers of deafness and how to protect it?
Generally speaking, when you discover that you have hearing problems, in fact, your hearing loss may have occurred for several years. In these years, not only your hearing has been slowly declining, but also your brain's ability to distinguish language and language. Analytical skills also begin to deteriorate. In other words, the overall auditory function is deteriorating, and the specific manifestation is the inability to hear and hear other people's speech clearly.
The deterioration of auditory function is difficult to reverse, especially the physiological deterioration of the inner ear tissue structure, which cannot be restored through medical means. In audiology, hearing aids can be used for hearing and speech rehabilitation to help you regain some of your listening and speaking functions. The hearing organ is used or lost.
(1) I can't hear the conversations of leaders and colleagues clearly, and I am always worried because I am afraid that others will misunderstand or affect my work.
(2) When family members talk to you, they often "ignore" you and answer questions incorrectly, which affects the harmonious atmosphere at home.
(3) I often cannot hear clearly when making phone calls or watching TV. I turn up the volume loudly, which makes my family and neighbors noisy.
(4) The elderly cannot hear, the content of sound information input to the brain is reduced, and the brain's ability to distinguish sound information is reduced, further aggravating the hearing impairment, which is manifested in the accelerated speech speed and the brain's ability to distinguish sound information. There is no time to distinguish and process, often hearing sounds and not understanding the meaning. In this way, the elderly are less willing to communicate with others and listen less, which often results in the elderly being lonely, depressed or grumpy, and their quality of life is reduced. Some are even prone to Alzheimer's disease.
(5) Research at home and abroad shows that as long as children have mild to moderate hearing loss, their language development and intelligence development will be affected.
Maintaining good hearing is extremely important. Medical experts point out that paying attention to the following points is very helpful to protect hearing.
1. Avoid all kinds of noise. Being exposed to noisy environment for a long time can easily lead to hearing aging. If you create a quieter working, studying and living environment, you can reduce the negative impact of noise on hearing.
2. Avoid making mistakes. Excessive mood swings can cause spasm and contraction of capillaries throughout the body, causing a severe slowdown of blood flow in the auditory vessels of the inner ear, leading to microcirculation disorders, resulting in hypoxia of the auditory nerve in the inner ear, leading to sudden deafness.
3. Avoid picking your ears randomly. Do not use unclean small wooden sticks, hairpins, etc. to dig your ears to relieve itching to prevent damage to the tympanic membrane deep in the ear canal, causingTraumatic tympanic membrane perforation and suppurative otitis media and other pathological changes occur, resulting in varying degrees of hearing loss.
4. Avoid using ototoxic drugs. Such as streptomycin, gentamicin, kanamycin, neomycin, quinine and its derivatives, etc., to avoid drug-toxic deafness. These drugs are especially prohibited for infants and young children.
5. Avoid the influence of high air pressure around the ears. For example, when participating in sports such as swimming and diving, be careful not to let your ears touch the water first; when setting off firecrackers, stay 3 meters away from the scene or cover your ears with your hands; do not hit people's ears with your palms, etc. All of these are to protect the inner tympanic membrane from being stimulated by air pressure and causing traumatic deafness.
6. Eat less high-fat foods. Excessive cholesterol concentration in the blood causes atherosclerosis in the blood vessel walls. Arteriosclerosis reduces the blood supply to the inner ear and causes malnutrition of the auditory organs, leading to hearing loss or deafness.
7. Actively treat colds. Because colds can affect the ventilation of the Eustachian tube (the tube from the pharynx to the middle ear cavity). In addition, if you blow your nose too hard and improperly, the germs in the nose may accidentally enter the middle ear cavity, easily causing middle ear suppuration and infection, and affecting hearing.
8. Avoid using the Walkman for a long time. High-volume audio sounds can cause fatigue and damage to the hearing organs, leading to hearing loss and even deafness.
Hearing experts recommend:
1. You should pay attention to protecting your hearing from young children. If you have itching in your ears, do not use unclean matches or Use pins to dig out the ears to avoid causing otitis externa. Swimmers can plug the opening of the external auditory canal with cotton soaked in disinfectant Vaseline ointment before entering the water to prevent sewage from infiltrating into the ear. People with colds are often accompanied by acute rhinitis and runny nose. When the nose is stuffy, if you point your nose hard, the pressure of the air will cause the mucus in the nasal cavity to enter the middle ear through the Eustachian tube that is connected to the middle ear, causing otitis media.
2. Elderly people go out more often and listen to natural sounds such as wind, rain, and birdsong. Research shows that these natural sounds can help protect your hearing and improve your mood. If you have limited mobility or time, downloading similar audio from the Internet can have the same effect. However, it is not recommended to wear headphones when listening, and it is best to use low volume loudspeaker mode.
