How to prevent deafness? Avoid noise stimulation!
summary
Listening plays a very important role in our life, but there are many factors in our life that can affect our hearing, even cause deafness. So in order to avoid the phenomenon of deafness, we should do a good job in the prevention of deafness, but how to prevent deafness? Let's take a look at the following.
How to prevent deafness? Avoid noise stimulation!
The first is to avoid noise stimulation - exposure to noise for a long time will make the hearing of the elderly who have begun to decline more prone to fatigue. The microvasculature of the inner ear is often in a spasmodic state, so that the blood supply of the inner ear is insufficient, the hearing will rapidly decline, and even noise induced deafness will occur. Research shows that one group of people living in noise environment, hearing loss is 60 dB, while the other group of people living in strong noise environment, hearing loss is 80 dB. Therefore, the elderly should try to reduce noise interference on hearing. When the inner ear is impacted by huge sound waves such as mountain shooting, jet aircraft, firecrackers, thunder and so on, the tympanic membrane can be damaged, resulting in hearing loss. When encountering the above situation, you can wear ear protection plug to deal with the stimulation of strong sound.
Second: beware of ear canal injury and infection - the elderly like to dig their ears with ear scoops and matchsticks. This is because the physiological blood circulation of the elderly is weakened, the secretion in the ear canal is reduced, resulting in a sense of dryness. Sometimes they feel itchy and unbearable. After ear pulling stimulation, they can get temporary relief. But it is easy to damage the ear canal, cause infection, inflammation, and even damage the eardrum. The correct method is to use a cotton swab to dip in a little alcohol or glycerin when the ear canal itches. Can also be oral vitamin E, vitamin C and cod liver oil, inner ear itching can be alleviated. In addition, it is necessary to prevent water from entering the ear. The elderly feel not sensitive enough. When they wash their face, they may bring sewage into their ears, but they do not feel uncomfortable. It is easy to cause infection and inflammation of the external auditory canal, affect the tympanic membrane, and affect their hearing.
Third: use ototoxic drugs with caution - elderly people have more diseases, and they often use antibiotics. However, it should be noted that the use of streptomycin, gentamicin, kanamycin and other ototoxic antibiotics should not be overdosed or used for a long time. They can be used alternately with other drugs, and they can also be treated with traditional Chinese medicine. Appropriate application of vitamin B complex and anti allergic drugs may prevent hearing loss.
matters needing attention
Quit smoking and drink less - because both smoking and drinking will have a certain toxic effect on the auditory nerve, especially nicotine, the harmful substance in smoking, if it enters the blood, it will lead to small vasospasm, blood flow more slowly, blood viscosity will also have a certain increase, it will also lead to insufficient blood supply to the inner ear, leading to the emergence of deafness.
