After staying up late, my head was groggy and dizzy
You must be familiar with such a feeling
What's going on in the head?
There is water in the brain, it is true
Medically it is called: cerebrospinal fluid
Don't underestimate it,
Can help you
"Brainwashing"
It's not some kind of 3D surround,
A lingering mysterious power
It's really cleaning the brain of "garbage."
Cerebrospinal fluid, constantly functioning
It can take away the metabolic waste products produced by nerve cells
At the same time, nutrition is provided
Especially after you fall asleep
Blood flows out of the brain
Just give the cerebrospinal fluid "free" the ground
Ability to carry out "cleaning tasks" more freely[1]
That's why I woke up
Will feel refreshed:
pi
p = 3.14159 26535 89793 23846
It seems to be able to memorize dozens of decimal places in an instant
(*At this time, it is exaggerated, and it is normal not to be able to recite it)
But the night before, you stayed up late
The "garbage" in the head could not be transported away
You will feel dizzy and doubt life
So it's important to sleep well
Brother Dian can't persuade you not to stay up late
They are all hit workers, they all understand
How busy your body also needs to be recharged, love yourself!
Say two more words about the water in your head
Those willing to watch can continue
Cerebrospinal fluid, don't look at the amount is not much
Total cerebrospinal fluid in adults
Approx. 150 ml[1]
Equivalent......
But it keeps the brain safe
The brain and spinal cord are fragile
Hardly withstands any squeeze[2]
Cerebrospinal fluid is like a "liquid pad" between the brain and spinal cord.
It plays a role in buffering vibration and dispersing pressure
Otherwise, you accidentally prostrate your head
Maybe it's a coincidence that I'm dying
Water in the brain is good stuff!
Final Myths:
Where does the water in my brain come from?
It's not something you drink into
Nor did you go in in the shower
It comes from our incredibly intelligent brains
One of them is called the lateral ventricular choroid plexus
And finally it went back into the bloodstream
Cerebrospinal fluid is a colorless, transparent fluid
As for whether it is "tasteless", let's not be curious
After all, I didn't have the chance to taste it
The brain is very "exquisite"
Updated every 6 to 8 hours[3]
Work 24 hours a day, all day, all day!
Committed to creating a fresh "water source"
When someone angrily says to you:
"You don't have water in your head?"
"The brain is not in the water??"
"Is there water going in?"?"
At this point, you just have to calmly go back
"Yes! There's water in everyone's head!
In life, there will always be all kinds of people
When questioned and insulted
Fight back with knowledge
Leave the other person speechless
The water in the brain is all wisdom
"Like, share, watch" a bit
