It's beautiful how it's designed.
I'm fascinated how it works.
The pulsing of the heart causes a vibration of the arteries inside the brain.
And with each pulse, the fluid that lives around them, like a sleeve around the blood vessel, it gets pushed into the brain milieu.
brain environment.
And then on the venous side, the fluid which rinses the brain and collects any junk or trash, things like the metabolic byproducts of chemical reactions that need to be cleared, or things like amyloid, which is a hallmark of Alzheimer's disease, gets cleared, gets rinsed with each pulse, and gets collected in the sleeve around the vein,
And then it goes to the top of the brain and gets cleared through what's called the sinus and the lymphatic system to get out of the brain.
So with each pulse, your brain gets clean.
And for some reason, this happens better and more effectively during sleep than during the day.
When you don't get enough sleep, you are preventing this rinsing process.
You're preventing the garbage collection that happens in your brain throughout the night.
And imagine if there was no garbage collection in New York for a month.
Just imagine what an ugly environment situation would be because dirt that doesn't get collected actually affects the neurons.
And so it's extremely important to sleep seven to eight hours a night because you need to have that process to happen in order for your brain to remain fresh and vibrant.
When you don't get enough sleep, all the junk accumulates.
It affects brain cells.
The brain cells can't function when it's dirty around them.
They can't function when there's too much magnesium, calcium, all the different enzymes.
They need to be cleared.
Neurons are very fragile and very delicate.
