40 分钟Welcome to Huberman Lab Essentials,
where we revisit past episodes for the most potent and actionable science-based tools for mental health,
physical health, and performance.
And now, my discussion with Dr. Matt Walker.
Let's start off very basic.
What is sleep?
Sleep is probably the single most effective thing you can do to reset your brain and body health.
Sleep as a process, though,
is an incredibly complex physiological ballet sleep is broadly separated into these two main types and we've got non-rapid eye movement sleep on the one hand and then we've got rapid eye movement sleep on the other when you go into REM sleep you are completely paralyzed you are locked into a physical incarceration of your own body amazing the brain paralyzes the body so that the mind can dream safely
Because think about how quickly we would have all been popped out of the gene pool.
If I think I'm one of the best skydivers who can just simply fly and I get up on my apartment window and I leap out.
you're done you're done now of course the involuntary muscles thankfully aren't um paralyzed so you keep breathing your heart keeps beating you go through these bizarre what we call autonomic storms there are only two voluntary muscle groups that are spurred from the paralysis bizarre one Your extraocular muscles,
because if they were paralyzed, you wouldn't be able to have rapid eye movements.
And the other that we later discovered was the inner ear muscle.
Some people have argued that the reason the eyeballs are spurred from the paralysis is
because if your eyeballs are left for long periods of time inactive,
you may get things such as oxygen sort of issues in the aqueous or vitreous humor.
Eyeballs have to keep the drainage systems of the anterior eye are made to require movement.
Exactly.
People with glaucoma have deficits in drainage through the anterior chamber.
