Common sense of ear care 1. Several measures to protect ears (physical knowledge)

In order to prevent frostbite and trauma, the ear shell is exposed on both sides of the skull. Except for the earlobe, it is composed of movable cartilage and skin, and the blood supply is poor. Winter and spring and cold areas are prone to ear frostbite, so pay attention to protection. Fighting, car accidents and other accidents, or parents discipline their children, often hit their ears with their hands, resulting in auricle tearing or tympanic membrane perforation.

After traumatic tympanic membrane perforation, it is forbidden to wash or drip medicine. Plug the ear hole with a sterile cotton ball and take anti-inflammatory drugs orally. Strict disinfection and aseptic operation must be carried out when piercing needle, cyst puncture or piercing eyes to avoid periostitis.

2。 Correct the bad habit of digging ears. There are sebaceous glands, cerumen glands and bristles in the ear canal, often accompanied by germs.

Some people like to dig their ears with hairpins, matchsticks and fingers. , causing skin damage to the external auditory canal, and abscess and periostitis are easy to occur after infection. Being hit by others when digging ears is easy to cause tympanic membrane rupture, and otitis media will affect hearing after infection.

As the saying goes, "you are not deaf unless you dig your ears" has some truth. 3。

Prevent ants, flies and insects from entering the ear. When children sleep outdoors in summer, small insects, centipedes, etc. Often mistakenly enter the ear canal. Patients with otitis media have a foul smell in their ears, which is easy to attract flies. They should be guarded by someone to protect themselves. In case of dripping oil or anesthetic into the ear, let it suffocate and die, then take it out and treat it according to the condition to avoid inflammation and deafness caused by infection.

4。 When swimming, prevent water from choking. When swimming, after the ear canal is filled with water, you can tilt your head to one side and jump a few times, and the water will automatically flow out.

When swimming, diving or diving, the nasal cavity coughs and chokes, and enters the middle ear cavity through the eustachian tube, which is easy to cause otitis media. People who have not mastered the essentials of the game had better not do diving and diving, and people with tympanic membrane perforation due to otitis media should be more cautious.

5。 Infant feeding and drinking water can prevent cough and suffocation. The eustachian tube is short, thick, straight and low.

Therefore, feeding and drinking water should not be rushed, and the position of the head should not be too low, otherwise it is easy to cough and choke, and secretions and milk enter the middle ear cavity through the eustachian tube, which is easy to cause infection in the middle ear cavity and affect future hearing. 6。

To prevent noise and explosive deafness, people who work in a noisy environment for a long time (noise is greater than 85 decibels) can cause sensorineural deafness; Loud knocking or sudden changes in atmospheric pressure can lead to inner ear damage and deafness. Preventive measures: reduce the intensity of sound source, operate at a distance or outside the barrier, and use muffler, air extractor and sound absorber when possible; You can also wear earplugs to reduce working hours or get rid of noisy environment.

Don't stay in noisy environment or where there is loud knocking at the door. 7。

Prevention of drug-induced deafness At present, there are at least 90 kinds of people who know that drugs and chemicals can cause deafness. Drug-induced deafness is more common, accounting for only 3% of acquired deafness in the 1950s, 35% in the 1970s, 43% in the early 1990s and 54% in the late 1990s. Common drugs causing deafness include kanamycin, gentamicin, streptomycin sulfate and neomycin.

Especially young children and the infirm are more likely to cause deafness. If drug-induced deafness can be found early and treated actively, some hearing can be restored, but most of them can not be cured in the later stage.

Drug-induced deafness is mainly prevention. For young children, the above drugs should be banned or used with caution, and should be used in accordance with the provisions of the Pharmacopoeia in case of emergency, and must not exceed the dose.

During the treatment, the children's response to noise should be carefully observed, or objective hearing examination should be done, such as acoustic impedance, auditory evoked potential, cochlear electrogram, auditory brainstem response, otoacoustic emission and so on. 8。

Exercise to prevent respiratory diseases. Exercise regularly, enhance resistance and immunity, and prevent the occurrence of respiratory diseases. Infectious diseases of upper respiratory tract such as influenza, whooping cough and scarlet fever are easy to induce acute catarrhal otitis media, suppurative otitis media, labyrinthitis and even deafness in severe cases.

After the children get the above diseases in the onset season, they should not only actively treat the primary disease, but also pay attention to the hearing situation of the children and go to the hospital for treatment in time. 9。

If diseases in any part of the ear are not treated in time, they may cause deafness of different degrees and durations, such as cerumen embolism, ear canal abscess, otitis media and sudden deafness. Should be treated in time to minimize hearing loss. Some systemic diseases, such as mumps, meningitis, septicemia, leukemia and aplastic anemia, can damage hearing.

Pay attention to hearing protection while treating the primary disease, and go to the otology department for examination and treatment in time. .

2. How to maintain your ears in your daily life?

There are three ways to maintain China ancient ears, all of which belong to the intersection of heart and kidney, that is, to coordinate the relationship between heart fire and kidney water, so as to achieve the purpose of health preservation.

Heart-kidney intersection method, as the name implies, needs heart-kidney communication. Ear points are substitutes for kidney qi, so this is the external manifestation of kidney.

The heart is mainly used at Laogong point on pericardium meridian, representing the heart. When it comes to the hand, we will say that our arms walk along the pericardium meridian, close to the midline of the body, and the fingertip of the middle finger is the well point of the pericardium meridian.

When we make a fist gently, the palm of our hand pointed to by the well point of the middle finger tip is Laogong point. In Chinese medicine, acupoints are empty places.

There is an important point of Taoist health preservation in the ear-hearing points, not acupuncture.

3. What are the listening tips to protect your ears?

One: Develop scientific eating habits.

Eating more foods rich in zinc, iron and calcium can reduce the lack of trace elements, thus helping to dilate microvessels, improve the blood supply to the inner ear and prevent hearing loss;

Two: use drugs with caution.

Some anti-inflammatory drugs, such as streptomycin, gentamicin, kanamycin and so on. If used improperly, it may have an irreversible effect on the auditory nerve.

Three: avoid long-term exposure to high-decibel noise.

Long-term exposure to high decibel noise will damage auditory hair cells and inner ear, which will lead to noise deafness.

Four: Overcome the bad habit of picking your ears.

Pulling out the ear is easy to damage the skin of the external auditory canal and bring bacteria into the external auditory canal to cause inflammation, which is not only difficult to treat but also painful. If periosteal perforation is caused, it will affect hearing.

Five: Beware of the bad influence of "neighbors"

Cold, upper respiratory tract infection, sinusitis, pharyngolaryngitis, epidemic cerebrospinal meningitis, Japanese encephalitis ... These diseases of ear "neighbors" may induce ear inflammation and lead to hearing loss, so mothers must not ignore their children's minor problems, and should find them in time and deal with them as soon as possible.

Six: It's best to blow your nose through your nostrils separately.

If the nose is stuffy, remember to blow your nose together, because the ear, nose and throat are connected together, and the pressure in the nose may cause inflammatory secretions to flow into the sinus or middle ear, which may easily cause otitis media.

Seven: Always * * ears to ensure blood circulation * * * can promote blood circulation in the inner ear and promote the effect of ear health care. For example, * * * auricle, pinching earlobe, and * * * Fengchi point are recessed on both sides of the hairline behind the neck. You can also close your eyes, insert the index fingers of your hands into the ear holes respectively, and then pull them out quickly, and do this for 10 times in a row.

4. How to protect our ears

(1) Avoid Noise If we want to protect our ears, we should stay away from noise in our daily life, which will harm our ears for a long time.

If people are exposed to the roar of machines, the noise of vehicles, the noise of human voices and other noises for a long time, the hearing that begins to decline is more likely to be tired, and the hearing will drop sharply, and even cause noise deafness. Therefore, avoiding or reducing noise interference as much as possible is the first priority for the elderly to protect their hearing.

(2) Don't dig around, and don't dig your ears often. It may be comfortable to dig your ears, but don't dig your ears often, it will do great harm to your ears. Frequently using an ear spoon and a match stick to pull out the ear, it is easy to knock against the ear canal, causing infection and inflammation, and may also damage the eardrum.

When the ear is itchy and uncomfortable, you can gently wipe the ear canal with a cotton swab dipped in a little alcohol or glycerin, or take vitamin B, C and cod liver oil orally. (3) Use drugs with caution and try to avoid ototoxic drugs, such as gentamicin, streptomycin, kanamycin and neomycin. Because the detoxification and excretion functions of the elderly are low, the use of these drugs can easily cause ototoxicity and damage hearing.

(4) * * Always * * ears in daily life to promote the blood circulation of ears, which is conducive to protecting the health of ears. * * * Yifeng point (the depression between the earlobe and the high bone behind the ear) and Tinghui point (the depression before and after the tragus and the posterior edge of the mandibular joint process) can increase the blood circulation of the inner ear and protect hearing.

Take * * * once every morning and evening for 5~ 10 minutes each time. Long-term persistence will be effective. (5) If the elderly who put out the liver fire are often in a state of impatience and irritability, the autonomic nerve will lose its normal regulatory function, causing ischemia, edema and auditory neurotrophic disorder in the inner ear, which may lead to a sharp decline in hearing or an outbreak of deafness.

Therefore, the elderly should try to keep themselves relaxed and happy. (6) Kidney-tonifying Chinese medicine believes that hearing loss is closely related to kidney deficiency.

Therefore, under the guidance of doctors, the elderly can take some drugs to tonify the kidney, such as Liuwei Dihuang Pill, Jinkui Shenqi Pill and Guiling Pill. And they can often drink walnut porridge, sesame porridge, peanut porridge, pig kidney porridge and so on. It is quite beneficial to protect hearing. .

5. How to protect your ears by listening to music with headphones?

In order to protect your ears and avoid hearing loss when listening to music with headphones, you need to pay attention to the following points: 1. Control the listening volume: when listening to music with headphones, pay attention to reducing the volume, which is soft and not harsh.

Listening to music with headphones should follow the "66" rule. Take MP3 as an example, that is, when listening to MP3, don't turn the volume to more than 60% of the maximum volume, and try to turn the volume to 40~60 decibels (generally a little lower).

2. Control the time of listening to music: Don't listen to MP3 for more than 60 minutes at a time. After using the walkman for a long time, you should rest your ears for a while to avoid hearing fatigue.

Experts suggest that adults should not use headphones for more than 3~4 hours a day, and teenagers should not use headphones for more than 1 ~ 2 hours a day, because their hearing organs are not yet mature. When listening to music with headphones, you can chew food or gum. Otolaryngology experts believe that chewing gum while listening to music with headphones can relieve the air pressure between the middle ear and the outside world and protect hearing. 4. It is best not to use a walkman for exercise, because aerobic exercise makes blood flow to the limbs, and the inner ear is more vulnerable to loud noise.

When listening to the walkman in downtown, in order to cover up the noise around, the volume is often turned up very loudly, which is more likely to damage the hearing. Therefore, experts advise not to use walkman in the street. If you have to listen, it is recommended to use closed or earphone type. 6. Choosing a good pair of headphones is also the best prevention method.
