As if we didnt have enough reasons to get at least eight hours of sleep, there is now one more. Neurons are still active during sleep. We may not realize it, but the brain takes advantage of this recharging period to get rid of junk that was accumulating during waking hours.
Sleep is something like a soft reboot. We knew that slow brainwaves had something to do with restful sleep; researchers at the Washington University School of Medicine in St. Louis have now found out why. When we are awake, our neurons require energy to fuel complex tasks such as problem-solving and committing things to memory. The problem is that debris gets left behind after they consume these nutrients. As we sleep, neurons use these rhythmic waves to help move cerebrospinal fluid through brain tissue, carrying out metabolic waste in the process.
In other words, neurons need to take out the trash so it doesnt accumulate and potentially contribute to neurodegenerative diseases. Neurons serve as master organizers for brain clearance, the WUSTL research team said in a study recently published in Nature.
Human brains (and those of other higher organisms) evolved to have billions of neurons in the functional tissue, or parenchyma, of the brain, which is protected by the blood-brain barrier.

(49,992 posts)Idiopathic hypersomnia is an uncommon sleep disorder that causes you to be very sleepy during the day even after a full night of good sleep. Its cause is unknown. It also often causes difficulty waking up after you've been asleep. If you take a nap, you generally don't feel refreshed and you may wake up confused and disoriented.
The need to sleep can strike at any time, including when you're driving a car or working, which makes idiopathic hypersomnia potentially dangerous.
The condition often develops gradually. Diagnosing idiopathic hypersomnia requires ruling out more-common sleep disorders. The aim of treatment is to control symptoms with medication.

I posted below that I listened to this podcast a couple weeks ago. Then today, I found this article. Weird coincidence.

I've started taking afternoon naps lately when I just can't keep my eyes open.

(7,113 posts)Up until the last 100 years or so, I'd imagine most people routinely got 8 or 9 or 10 or more hours of sleep. Those who had to get up at dawn to milk cows and such probably went to bed early, not long after the last meal of the day was done.

(3,504 posts)I've worked night shift most of my adult life. And you can 'trick' your body into believing that daytime is really night time -- when i would come home after work, a while after dawn, I would have my 'supper' and go to bed with black curtains over the bedroom windows and turn on some white noise so that I wouldnt be disturbed by neighbors mowing their lawns.
But, of course, weekends screw with that deception; your wife and kids are NOT going pretend that 10AM is the middle of the night!
Like all lies, the ones you tell your body DO catch up to you!

(4,399 posts)So they slept while it was dark but usually got up for an hour or two in the middle of the night and then overall still got 8 or so hours of sleep. That gave them a chance to put more wood on the fire, do some quiet chores, and make more babies given lots of families only had one or two beds and all slept in the same room.

(36,109 posts)sleep all he wants once he's in prison. He suffers early dementia and severe narcissistic disorder. So there's no rehabilitating that brain.
Right now as a criminal defendant, like it or not, he must behave himself and honor court justice.

(8,053 posts)Thanks for this post. As I've progressed in years (a.k.a. gotten older-LOL) I'm sleeping a lot more! I normally take a nap (that's at least an hour-and I've read that in some cases it's healthier to limit one's naps to about 30 minutes -but anyhow) I've been sleeping at least eight hours a night and sometimes nine....

(4,544 posts)Now that I am retired from working outside my home and do all my work online from home and mostly at night, it is less of a problem, but I have been plagued with this and perpetually sleep-deprived most of my life. I have come to the conclusion that my (and my daughter's) circadian rhythm is just different.
I recently was traumatized by a technician at a "sleep study" my doctors wanted me to do. It was from 7pm to 5am. I told them I didn't think I would be able to sleep much, if any. They said I should try it anyway.
I went prepared to give it my best shot. I have a Kindle on my tablet that I have set to black background with pale cream text, with brightness as low as it will go and a blue light blocker turned on. Reading is my best bet to lull my brain to shut the hell up, and it usually works with the Kindle. I had told the tech I would need to read on my Kindle to get sleepy. He didn't say I couldn't.
So, I was doing this, but around 11:30pm, he came in my room to yell at me and told me I had to "turn off all lights, no electronics, relax, and go to sleep" because he had a study to do. I told him
it wasn't even near my usual bedtime, and tried to explain again what I needed to do, but he wouldn't listen.
He told me if I didn't do what he said, he would report me as "uncooperative." WTF? I even asked him, "You work nights, right? Could you do what you are telling me to do?" He said, "No," but still insisted that I had to obey his commands. Or else.
So, I did what he insisted and laid there unable to sleep (and now I was freaked out and angry) all night. He reported me as "uncooperative" anyway, said that I used "bright electronics all night," and "refused to go to sleep." More WTF??!!
I'm in the process of reporting him and trying to get that language struck from my medical record because it's untrue. I get really tired of being discriminated against and shamed (people think we're "lazy" ) because I'm different. This was a horrible experience.

(4,015 posts)For example, Last night, I went to bed very early on purpose, hoping to improve my energy and focus. I ended up getting 12 hours of sleep. Today I'm feeling quite refreshed.

(12,393 posts)Everyone knows that the Sandman tiptoes in to the house, regardless of how many doors are locked, and blows sand in your eyes. That is what puts you to sleep. Then all kinds of variables take place. On certain nights, the bogeyman sneaks out of the closet and you run around for hours from this maniac wielding a chainsaw. Other nights, just as you are comfortably sinking into dreamland, the tooth fairy comes around and starts yanking on your pillow. And once a year those reindeer park on your roof to drop off the fat guy who you never catch, no matter how late you stay awake.
Its a jungle out there.
