Believe it or not, When you fall asleep, you are really brainwashed. Scientists at Boston University took an unprecedented picture of the cleaning process, here you can see the picture below:
During sleep, the brain cleans itself and detoxifies, and it becomes stupid if it is not cleaned and detoxified sufficiently.
Red is blood and blue is cerebrospinal fluid. What’s amazing is that it hasn’t been discovered before, and the blood will flow out of the brain periodically. Whenever a large amount of blood flows out, the cerebrospinal fluid takes the opportunity to launch a wave of attacks.
After entering the cerebrospinal fluid, it clears toxins, such as Beta-amyloid, which causes Alzheimer’s disease.
And this kind of cleansing can only be done after falling asleep, so that people wake up and have a refreshing brain; when they are not asleep, the cerebrospinal fluid does not have a full opportunity to enter.
In addition, the researchers also discovered the relationship between brain electrical activity and the cleaning process, which means that brain waves direct the movement of liquids.
When we are awake, the brain neurons cannot be closed and opened at the same time, the blood flow of the brain cannot be reduced to a low enough level, and the cerebrospinal fluid cannot take advantage of the opportunity to pour in to complete the tasks of brain cleaning and detoxification.
So, white collar workers, remember to sleep more and don’t stay up late. Brainwashing can’t be finished, maybe you will really become stupid.
Why can you brainwash only when you fall asleep?
When you fall asleep, the brain goes through several different stages: After falling asleep, light sleep, deep sleep and sound sleep, we will enter the rapid eye movement (REM) sleep period, which is a state of easy dreaming.
Scientists collectively refer to the first four stages as the \”non-rapid eye movement
period.\” This new research focuses on the non-REM stage, which is a very important stage for the brain to retain memory (Memory Retention).
In fact, studies have proved that during sleep in mice, toxins like Beta amyloid are eliminated from the brain, that is, the cleanser for the brain is called cerebrospinal fluid.
The question is, how did it get rid of? Why can it be cleared only when sleeping?
Scientists did an experiment in which 13 humans put on EEG caps and slept in an MRI machine. An electroencephalogram will show which state of sleep a person is in; and MRI will measure blood oxygen levels and show how much cerebrospinal fluid flows in and out.
Then a strange phenomenon is found:
The blood oxygen concentration in the brain has obvious major periodic changes. In other words, blood flows out of the brain on a large scale and periodically.
At this time, cerebrospinal fluid will take the opportunity to rush into the brain, filling up the space left for it.
After waking up, the major cycle is gone, and there is no way for the cerebrospinal fluid to rush into the brain in large quantities to complete an effective cleaning.
When a large number of neurons stop firing together, there is no need for so much blood to transport oxygen, which gives the opportunity for cerebrospinal fluid to flow in. In this way, we have the scene we saw at the beginning.
This finding is very important. It tells us that sleep has a very special function:
When we are awake, neurons don’t turn on and off at the same time. Therefore, there is no way to reduce the blood volume of the brain to a sufficiently low level when awake.
Only after falling asleep, when there is not so much blood in the brain, can the cerebrospinal fluid circulate freely and remove metabolic byproducts such as Beta amyloid.
The in-depth research has also opened up new treatment ideas for the treatment and prevention of neurological diseases such as Alzheimer’s disease (Alzheimer’s disease) and autism.
Previously, drug development for Beta amyloid has been in trouble frequently, but now, scientists have pointed out that perhaps not focusing on specific molecules that work, but focusing on increasing the total amount of \”brainwashed\” cerebrospinal fluid will become an effective solution.

As the proverb goes, “No one knows the value of health until loses it.” In other words, nothing is more than health. Therefore, I give here the advice to all white-collar workers never to stay up late, otherwise, you’ll really become stupid! If you get ill, it is nearly impossible for your career effective. much less make your dreams come true. We should always keep the point in mind: Health is very important to us all. Those who are rich but lose their health are more unfortunate than those who are poor.
