People are old and have bad hearing.
But nowadays, "deafness" is no longer a patent for the elderly, and more and more young people are beginning to be 'deaf before they are old".
According to data released by WHO, about 1.1 billion young people (between the ages of 12-35) worldwide are currently at irreversible risk of hearing loss.
From 2008 to 2018, hearing loss on the mainland increased from 74 million to 96 million.
Why are more and more young people becoming "little deaf"?
------ this is closely linked to the lifestyle of young people.
After sleeping with headphones on for a long time, the 24-year-old man eventually lost hearing in his left ear
Recently, according to media reports: a 24-year-old man from Xi'an, Shaanxi Province, fell asleep wearing headphones for a long time, resulting in neurogenic hearing loss of the left ear sensory voice.
It is reported that the man has been wearing headphones to sleep for half a year, and the loss of hearing and accompanied by tinnitus symptoms has also caused a great impact on life.
Why does wearing headphones hurt my hearing?
According to national regulations, a volume of more than 50 decibels is noise. It is the presence of these noises that causes the ears to be damaged to varying degrees.
While the maximum volume of an Apple headset can reach 150 decibels, long-term continuous noise and short-term strong noise will cause hearing loss that cannot be reversed, and the noise will destroy the hair cells in the cochlea, resulting in the damaged hair cells can not regenerate.
Therefore, even after long periods of stopped noise exposure, hearing loss cannot be reversed.
Hearing loss eventually affects the understanding of speech and negatively affects the quality of an individual's life.
Compared to visual impairment, hearing impairment is less easily noticeable
People with hearing loss are prone to tinnitus, if you have a regular tinnitus situation, and when the tinnitus is heard, there is still a buzzing sound in the ear.
This indicates that your ear has been damaged, and it is recommended that the patient go to the hospital in time for examination.
Hearing-impaired people will have a decrease in sensitivity to sound, if your sensitivity to sound is not as high as others, you need to go to the hospital for a special examination, do not blindly use drugs, so as not to bring harm to your body.
In addition to noise, poor ear habits are also the main cause of hearing loss
First, make long phone calls
Many young people will like to "cook phone porridge", a dozen is a few hours.
However, frequent or prolonged telephone calls, like headphones, the ear is continuously exposed to noise, which can damage hearing and may also cause neurogenic deafness.
Second, pluck your ears with a hard object
Some people are accustomed to plucking out their ears, especially like to use hard objects to pluck their ears, which is not only easy to damage the ear canal, but also damage the eardrum, and it will be easy to let bacteria enter the ear canal, increasing the possibility of infection, thereby damaging hearing.
Third, regular clubbing, KTV
Studies have shown that 37% of hearing disabilities are closely related to noise impairment, which can slowly and uninterruptedly damage hearing.
Therefore, for entertainment venues with large volumes such as bars and KTV, it is necessary to control the number and time of going as much as possible.
For people with colds or too much fatigue, due to weak immunity at this time, if they are attacked by high decibel noise, they may cause sudden deafness.
Fourth, suck hard or blow your nose
Blowing or sucking hard, the nose will run from the airway to other places, causing the pressure in the ear to change.
Part of the nasal discharge into the sinuses can cause sinusitis, which causes the nose to squeeze into the tear duct and then cause conjunctival infection, and even squeeze into the Eustachian tube to cause otitis media.
It is recommended that patients change these habits as soon as possible and develop good ear habits, which can prevent their hearing from being damaged and make their ears healthier.
Once there is an abnormality, the patient should go to the hospital in time for medical treatment and develop good ear habits, so as to prevent the continuous development of the disease and bring irreversible damage to the ear.
When flying in the event of take-off or landing, it is best to do a swallowing action
Since the aircraft takes off or lands, the air pressure in the cockpit will change accordingly, and the gas containing the air cavity will also expand or shrink.
If the air pressure in the middle ear cavity cannot be quickly balanced, it is easy to cause aviation otitis media.
Therefore, during take-off or landing, it is necessary to take the initiative to do swallowing action, so that the Eustachian tube is in a constantly open state, which is conducive to maintaining the balance of air pressure inside and outside the middle ear.
