Everyday life
We often see some people
Whether it's walking, fitness or brushing up on drama
……
Will wear headphones
Gradually
Headphones have become in our lives
One of the indispensable necessities
But
Do you feel it？
If you wear headphones for a long time
The ears will feel uncomfortable
Why?
What exactly do headphones do to the ear?
Let's take a look
Originally
To listen well
It relies on inner ear hair cells
Its main job is
Transmits external sounds to the auditory nerves
But it's delicate
It belongs to nerve cells
It cannot regenerate after damage
If you wear headphones for a long time
Let the ear receive more than 85 decibels of noise continuously
The hair cells will always be in a working state
Over time, it will "strike in place"
And it can't be fixed yet
Other than that
Plug the headphones into the ear canal for a long time
It is also easy to breed bacteria
Causes infection
So
The effect of headphones on the ear can be imagined
Although headphones can have an effect on the ears
There is no need to discard it
Be careful not to wear headphones for too long
It is best not to continue for more than an hour
Don't make the headphones too loud
It is best not to exceed 60 decibels
If there is hearing loss, tinnitus, etc
Be sure to see a doctor in time!
