1. Wear headphones correctly:
The principle of “60-60-60” shall be followed when wearing headphones. That is, the volume shall not exceed 60% of the maximum volume, and the continuous wearing time shall not exceed 60 minutes. When using, the external sound environment should not exceed 60 dB. This is because wearing headphones for a long time will compress the external auditory canal, resulting in swelling and pain due to poor blood circulation. In addition, due to air tightness, the ear canal becomes damp and muggy, resulting in external auditory canal inflammation. Second, when the volume exceeds 85 dB, it will cause a certain degree of hearing damage, while the maximum volume of general mobile phones will reach 115-120 dB.
2. Use earplugs correctly:
Earplugs are also harmful to hearing. It is recommended not to use earplugs as far as possible. However, the use of earplugs in noisy environment can reduce the damage of noise to hearing. For example, in noisy places such as sports venues, performance sites, fitness squares and construction sites, due to long-term exposure to the noise environment, the microvessels in the inner ear will have spasmodic contraction. If it is not alleviated, it will also affect the blood supply and oxygen supply of the inner ear, resulting in a sharp decline in hearing.
3. Be optimistic and relaxed:
In daily life, we should relax and be optimistic to avoid excessive mental tension or constant anger, because when people are nervous or angry, the level of adrenaline in the body will rise. As soon as adrenaline rises, the arterioles in the ear will contract spasmodically, and the blood in the ear will be slow, causing ischemia and hypoxia, leading to sudden deafness.
4. Pay attention to nutritional balance:
Vitamins A, B and C can protect your ears. Pay attention to eating more foods rich in vitamins A, B and C in your daily life. Foods with more vitamin A, such as carrots, spinach, green peppers, eggs, milk, animal liver, etc; Foods with more vitamin B, such as egg yolk, malt and some coarse grains; Foods with more vitamin C, such as fresh jujube, kiwi fruit, pineapple, cauliflower, Toona sinensis, etc.
5. Early diagnosis and treatment:
Check regularly. If any abnormality is found in the ear, go to a regular hospital for diagnosis and treatment as soon as possible, so as to achieve early detection, early diagnosis and treatment without delaying the condition.
Earwax can protect the skin in the external auditory canal, block dust and prevent ear canal dryness.Dig the ear is a bad habit. When digging the ear, it is easy to damage the skin of the external auditory canal, cause external auditory canal damage, and even cause infection; In addition, there is a membrane in the ear that separates the outer ear from the middle ear, which is called tympanic membrane. Its function is to protect the middle ear and inner ear, transmit and improve sound. The tympanic membrane is very thin. If you accidentally pierce the tympanic membrane, causing tympanic membrane perforation, it will cause middle ear and inner ear infection and damage hearing.
2. Don’t blow your nose by mistake:
When some people blow their nose, or some parents help their baby blow their nose, they often pinch their nostrils on both sides and blow hard or let their baby blow hard. In fact, this will make the bacteria in their nose flow back into the middle ear, which is in danger of causing otitis media.
3. Don’t lie down to feed:
“Eustachian tube” is a tube connecting the oral cavity, pharynx, nose and middle ear. The tube of the baby is short, flat and straight. If mother is lying feeding, when the baby chokes, the milk is easy to be injected into the baby’s middle ear and cause otitis media. So no matter how tired you are, don’t lie down and feed!
4. Don’t give your baby medication:
If the baby is unwell, please do not take medicine for the baby by yourself, because you are not a doctor. Some drugs are particularly damaging to the ear. Taking them indiscriminately will cause permanent deafness of the baby, such as streptomycin, etc.
