Are our ears still working while we sleep?

When we sleep, our ears will actually enter a state of rest, but because the ears are very sensitive to sound, if the outside world is very loud when sleeping, it will also cause the ears to react. Therefore, people are often awakened when they are sleeping, because they hear the noise of the outside world. But if these sounds are not particularly loud, they cannot be heard by the ears.

Moreover, the amount of external information that the ears can receive when sleeping and the sensitivity of the ears actually have a lot to do with the depth of the brain entering sleep, generally when the brain enters deep sleep.

, the ears will also rest more thoroughly, and the general sound will not be able to attract the attention of the ears at this time. But if the brain is still in light sleep, a small movement of turning over may be enough to wake people up, and the ears are very sensitive.

Although the ears rest when sleeping, the ears are also considered to be a very responsible organ, and the state of the ears is different at different times. Because the ear can collect information from the outside world, so that people can always keep in mind. Only in deep sleep, the ears can basically block all sounds, but as the degree of sleep weakens, the ears will begin to collect sounds to varying degrees, so the ears are not in a state of rest throughout the whole sleep process, and they still have to do their job a little more than the brain.

And many people in order to ensure the quality of sleep when sleeping, will choose to use earbuds, the use of earbuds to block all the ears, so that you can completely isolate the sound of the outside world, even if the ears wake up before the brain, has begun to work, but due to the role of earbuds, the sound of the outside world can not cause the response of the ear, so the quality of people's sleep will also improve, you can wake up naturally, without being woken up by the noise of the outside world, such a sleep state is the healthiest way for the human body.

It doesn't work, and the ears also need to rest, because when people are sleeping and resting, some sensory organs also need to rest, unless a louder sound will make it work again.

Of course, at work, it is impossible for us to sleep when the ear nerves are also resting, this is impossible, when people are sleeping, the ears are completely awake in the subconscious, otherwise something will come out, shouting and not waking up, it will be over.

When you are not working, you should also rest.

As a general rule of thumb, if you sleep well in your own home, you can sleep peacefully at home; But if you sleep in the wild, you will wake up easily and be more sensitive to the movement around you. In addition to vision, other senses can still play a role in falling asleep.

Human society is a highly complex form of organization, with city-states and rules that dictate what people can and cannot do. With the barrier of the door, outsiders or wild animals can not enter and exit at will, it is a safe environment for people at home, so in their own home, there is generally no and very little external danger, in that environment is generally quieter, people are easy to fall asleep and sleep relatively deeper. When you sleep, you can't see anything except when you close your eyes, except that your eyes need light.

However, because ** can still contact objects, the nose is still breathing, the human body is also dissipating heat, and the ears are generally not blocked and can still receive external sounds (mechanical waves), so there are also touch, smell, hearing, and temperature. After people fall asleep, the activity of subjective consciousness is reduced, and the function of these sensory organs is still playing, they are not controlled by subjective consciousness, but regulated by autonomic nerves, except for plugging and covering our ears, we ourselves have no way to stop hearing function, as long as it is not a loss of hearing function, it can also play a role after falling asleep. How else would we wake up a sleeping man?

Naturally, the sensations are still there.

In terms of biological structure, the nerve center of the auditory system is located in the auditory structure in the brainstem and cerebral hemispheres above the auditory nerve, the brainstem is responsible for collecting information, and the corresponding cortex of the brain interprets the sound information. Therefore, whether people can hear sound after falling asleep may depend on the quality of sleep, in a safe environment tends to sleep to death, the cerebral cortex works very little, the feedback of sound information is not obvious, and not very safe may bring danger to people in the environment, people are sometimes in light sleep, and the auditory system is still more sensitive.

Children fall asleep more obviously, sometimes while the child turns over during sleep, call their name, they will also agree, occasionally can have a vague conversation, but they themselves have no memory of this matter, because in the state of sleep, the activity of various parts of the subjective consciousness is reduced, and when turning over and other activities, the depth of people's sleep will be the first to be affected, so they may be sensitive to sound information.

This has a certain relationship with the evolutionary history of human beings, human beings in history live in caves and tree nests in the wild, and may encounter fierce beasts, which is quite dangerous to human beings, human long-range hearing is not very good, but it is more sensitive to nearby sounds, and human hearing range also covers the sounds that humans may encounter, and the sounds made by animals that are dangerous to humans, if the sensation is abnormal, people will wake up quickly. When some cold water suddenly drops on the face, the person will wake up quickly, and when the sleep is hot, the quilt will be wrapped tightly when it is cold, and the person who is asleep does not know it.

Yes, our body cells are divided and coordinated, part of the work and part of the rest, the same is true of the ears, only loud voices can wake us up.

At work, otherwise the alarm clock would not wake us up in the morning, and something would not wake us up.
