In the past 16th national "love ear day", this year's "love ear day" theme is "safe use of the ear, protect hearing The theme of this year's Ear Care Day is "Safe Ear Use, Protect Your Hearing". This year's theme is "Safe Ear Use, Protect Your Hearing." This theme addresses hearing damage caused by noise. This type of hearing damage is common and preventable throughout the world and should be taken seriously.
Noise is a major cause of hearing disability.
Studies have shown that noise is a major cause of hearing disability. Many young people like to go to noisy entertainment occasions to release themselves, such as bars, KTV, square dancing, etc. If they are in such an environment for a long time, it is easy to cause hearing damage. Others like to listen to music with headphones on all the time, often turning the volume up extra loud to immerse themselves in the world of music.
Experts say in fact this behavior is inappropriate, it is best to pay attention to listen to the time control within an hour, the duration of no more than 45 minutes.
, first of all, to have a sense of prevention of noise deafness. Noise damage to hearing can be divided into acute acoustic damage and chronic acoustic damage of two kinds, the former is mainly due to high-intensity impulse noise caused by transient exposure to auditory damage, most often seen after the blast, also known as blast deafness. Acute acoustic injury can be treated according to sudden deafness, while chronic acoustic injury is due to long-term persistent noise stimulation caused by auditory damage, it is difficult to cure, can only rely on prevention. Therefore, it is important to establish the awareness of noise damage to hearing.
Second, pay attention not to stay in the noisy entertainment environment for a long time. When you go to KTV to sing, you can reduce the intensity of the music and microphone, and control the volume and time when listening to music on headphones. If you live in a noisy environment, you can properly install some soundproof materials at home to reduce noise pollution. Again, to improve their own quality, do not let themselves become a source of noise, affecting the people around them, such as public **** occasions to play music, driving indiscriminately honked the horn and so on.
Watch out for drug abuse leading to deafness.
Clinical some drugs can damage hearing, produce dizziness, tinnitus, deafness and other symptoms, these drugs are often called ototoxic drugs. Antibiotics are now known as ototoxic drugs in the more common class, such as aminoglycoside antibiotics in streptomycin, kanamycin, neomycin, gentamicin, etc., as well as antipyretic and analgesic drugs such as aspirin, and other common ototoxic drugs such as contraceptives, anesthesiologists, antidiabetic drugs.
Most of the side effects of ototoxic drugs are irreversible and should be used with caution. In fact, many ototoxic drugs can be replaced by alternative medications. In addition, adult medication is different from children's medication, some drugs are fine for adults, but the side effects of children's use can be significant. For example, the treatment of otitis media drug of oxfloxacin, adult use will be very good therapeutic effect, but minors under 18 years of age is not suitable for use, parents should not take it for granted to give the child to use the drug, to avoid the child's hearing suffered damage.
In addition, there are many people who believe that deafness in old age is a natural phenomenon, neither to check, not to seek treatment. Experts pointed out that such a concept is not scientific, because the elderly frail may need to take medication often, in addition to antibiotics, aspirin, anti-inflammatory drugs, etc., should be taken correctly under the guidance of a doctor.
Hollowing out the ear is easy to damage the ear canal.
Pulling out the ears is often in our daily life to carry out the "activities", not only to clean, but also because of pulling up particularly comfortable, addictive. Many people also like to pull out each other's ears, but it's easy to damage the skin of the outer ear canal and bring bacteria into the ear canal.
The skin of our outer ear canal is very delicate, and the cartilage membrane is very close, the subcutaneous tissue is less, the blood circulation is poor, pulling out the ear when the force is not appropriate will cause damage to the outer ear canal, infection, resulting in inflammation of the outer ear canal, ulceration, and even affect the opening of the mouth and eating. Some people's ears itch, but also casually with a hairpin, matchstick, ear scooper, etc. very deep, very hard to pull out the ears. Our tympanic membrane is a very thin membrane, this hollowing out is very easy to injure the tympanic membrane or auditory ossicles, resulting in perforation of the tympanic membrane, affecting hearing, and even lead to otitis media.
Earwax is medically known as cerumen, which is formed when the normal secretions of the skin of the ear canal are combined with dander. Generally a small amount of flaky cerumen will be discharged on its own with the vibration and jaw movement during exercise. Large hardened cerumen should be removed by an otologist with a specialized tool, and should not be pulled out by yourself. If it is really itchy, you can use your hand to gently rub the outside of the ear, or gently rub with a cotton swab, but don't reach too far in.
