To his credit, he decided to test his theory. By not sleeping. During FINALS WEEK. He said, by the third day, he saw Tom Sawyer and Huck Finn walk across the pages of the book he was reading, and decided it was time to take a nap.
But, hey, I tried smoking banana peel, ala the Anarchist's Cookbook, so I don't have any room to talk.
I think the longest I ever made it was 70 hours. Maybe 80. I had two finals on consecutive days so I stayed up to cram for the second. Fibbed to my parents about when I was available to come home for the holidays, so I went to the computer lab to binge games with a couple friends, never made it to sleep that night.
I went to bed when the blue background on the computer terminal started to swim. That’s enough internet for me today.
The older you get the more dangerous it is to do this. You can start dying sometime between 70 and 120 hours. And the quality of whatever you’re doing is declining rapidly after 30 or so. Go to bed.
Which surprises me because I thought we were all taught that REM is the best kind of sleep (and the hardest to induce). But also doesn't Ambien reduce the amount of time in REM and increase NREM.
I'm confused again. Someone better educated than me care to explain?
It's unfortunately more complicated than this: we also clear out the same waste products in our brain during wakefulness. Mostly at a higher rate, too. Perhaps there's some unique way in which this happens during sleep but this certainly isn't the "key" (if there is in fact one) to why we need to sleep.
Now we basically do: sleep is when you clear out waste products in your brain. As someone who definitely doesn't understand all the details, it's when "channels" it your brain get opened up so these waste products can be swept away. This study (based on the title) claims to show the mechanism for doing that:
1. Norepinephrine-mediated: norepinephrine is a neurotransmitter, so this is saying it's responsible for the mechanism of action.
2. slow vasomotion - you can Google what vasomotion means, but it's essentially a rhythmic change it the walls of blood vessels - this is essentially the "sweeping away" part I mentioned above.
3. glymphatic clearance - the glymphatic system in the brain is that network of fluid filled spaces in the brain, and it's what clears away brain waste products, so glymphatic clearance means allowing the glymphatic system to "wash away" those waste products.
So, this study claims to explain the mechanism by which waste products get cleared from the brain during sleep, and the larger context is that it is indeed why we need sleep in the first place.
