What are some of the movie clips that can be automatically dubbed in the mind?
The first ---- that Dr. Xiaokang thought of was the dialogue between Charlotte and the great uncle in "Charlotte Troubles":
Of course, in addition to laughing, it is natural to "diagnose" this uncle as the back of the ear.
All along, everyone believes that when people are old, their ears are naturally not good, after all, the elderly will have senile deafness in all likelihood.
However, from the data of recent years, it can be seen that today's "deafness" is no longer exclusive to the elderly.
At present, 1.1 billion young people around the world will become "little deaf people"
According to a set of data released by WHO in February this year, about 1.1 billion young people aged 12-35 years old are currently at irreversible risk of hearing loss.
As can be seen from the data, from 2008 to 2018, the number of people with hearing loss in China increased from the original 74 million to 96 million.
Who predicts that without action, 630 million people worldwide will suffer from disabling hearing loss by 2030, and in 2050, this number will rise to more than 900 million.
Why are your ears bad at a young age?
1. Bad ear habits
Headphones have become one of the best ways for young people to avoid socializing.
However, long-term wearing of headphones, high-frequency noise in headphones will cause irreversible hearing loss.
According to a survey in China, the current headphone use rate of college students has reached 99.8%, and after long-term use of headphones, 28% of students have noise-induced hearing impairment, and 13.4% of students have chronic tinnitus.
What's even more frightening, however, is that people are often unaware of hearing loss.
2. The ear is caused by trauma
If the ear suffers from external injury, it will also directly affect the person's hearing.
Many people whose ears are hit or injured do not attract attention and eventually lose their hearing.
If you usually do not pay attention to protecting your ear health, so that the external ear canal is scratched, or a strong impact, it will also cause the eardrum to be injured, and over time, a serious ear canal disease will be formed, resulting in hearing loss.
This happens more often in life.
There is also a situation that when you use an ear scoop to clean the ear, you will use too much force, or do not pay attention, so that the ear scoop hurts the eardrum, which will also lead to hearing loss.
3. Unhealthy ear picking habits
In fact, normal ear droppings do not affect the health of the ears.
Ear feces are mainly from the skin of the external ear canal Sebaceous glands normal secretion, it can form a protective film in the ear canal, it will isolate microorganisms, small insect volume and other stimuli.
However, if you repeatedly pluck the ear, or use some hard objects to pluck the ear, such as a metal ear scoop, etc., the already delicate external ear canal skin and periosteum are damaged.
Mild cases may cause ear pain, bleeding, etc., and in severe cases, it may cause middle ear infections and ear pus, causing hearing loss.
In addition, KTV, bars, nightclubs, video game cities and other places that young people like, high decibel noise stimulation will also continue to damage hearing.
Once the hearing is damaged, it is really irreversible
Regardless of the length of time, as long as the ear is exposed to a huge high-decibel noise, it will cause fatigue of the auditor's sensory cells, and then temporary hearing or tinnitus.
However, if the exposure is prolonged or the volume is particularly large, it may last for a long time, which will trigger permanent damage to other structures of the sensory nucleus, resulting in irreversible hearing loss.
Gradual loss of hearing can affect speech comprehension, which can negatively affect an individual's quality of life.
Therefore, I would like to advise young people to protect their little hearing.
Keep the volume low, use the right headphones, limit the amount of time you spend each day using your personal audio equipment, pay attention to the level of hearing safety, wear earplugs in noisy places, etc.
All these details can prevent our hearing from suffering greater damage.
As the saying goes: look at the six ways, listen to the eight directions.
Whether it is hearing or vision, we all need to guard it well.
