There is also a particular area of sleep called slow-wave sleep. I immediately liked this idea. It turns out this part of sleep is where the brain basically gets into step with itself and gets into this one single phase of these relatively slow brain waves - around 10 Hz or so - and the whole brain 'fires all at once'. This is a brilliant bit of sleep where we consolidate memory and learning, and memory is one of my obsessions really.
I meditate all the time. You know, I don't sleep much - it's a known fact that sleep is required more for the brain than the body because the brain needs sleep to dream. But I dream all the time. I dream when I'm awake, when I create work, with my eyes open. So who needs sleep?
Just as important as getting enough sleep is thinking about sleep in the right way. Stop thinking of sleep and naps as “downtime” or as a “waste of time.” Think of them as opportunities for memory consolidation and enhancing the brain circuits that help skill learning. Nor should you feel guilty about sleep. It's just as crucial a part of successful brain work as the actual task itself.
I was too jitterbuggy happy to sleep, and the whole day kept playing in my brain's little screening room.
Whate'er thy joys, they vanish with the day:
Whate'er thy griefs, in sleep they fade away,
To sleep! to sleep!
Sleep, mournful heart, and let the past be past:
Sleep, happy soul, all life will sleep at last.
So when you're in REM sleep, your brain is very active, our body is quiet, but your brain is really processing a lot of things, a lot of emotions; we dream the most in REM sleep. And then you go back down in the deep stages, and so on and so forth.
We actually don't know the function of sleep all that well yet, but sleep is a time of quiescence in the brain.
Political conflict rests to a very large extent on a universal ignorance of consequences, as the people who are benefited by any particular act or policy are rarely those who struggled for it, and the people who are injured are rarely those who opposed it.
Dream sleep provides a fascinating neurochemical soothing balm. It is during dream sleep and only during dream sleep when our brain shuts off a stress-related neurochemical called noradrenalin.
Sleep paralysis is something that is actually very common. Many people have it, I've had it myself. And what happens is, when you're in that REM stage of sleep, your brain is very active. You're dreaming your most during that stage, you're mind, your eyes are moving, there's a lot going on. It's like fireworks going on in your brain.
It is most important to allow the brain the full measure of sleep which is required to restore it; for sleep is to a man's whole nature what winding up is to a clock.
You're trying to sleep off a debt that you've lumbered your brain and body with during the week, and wouldn't it be lovely if sleep worked like that? Sadly, it doesn't. Sleep is not like the bank, so you can't accumulate a debt and then try and pay it off at a later point in time.
Emily said ... Well, I read that it's important to sleep. While you sleep, the hippopotamus in your brain replays things that happend during the day, e.g. what you studied. So therefore it remembers it for you.
No one knows the complete function of sleep. Is it to reset the brain or give it more of a rest period? Is it for cleaning the brain of all the garbage protein? For me, talking about these things as a non-biologist is fascinating.
Something was causing me not to be able to sleep, and then after a while your brain doesn't want to turn off and go to sleep. And so it was constant battle with that. But as soon as I had the neck surgery, I started sleeping again.
My brain is always whizzing around with worries: could I have done an interview better? Have I prepared enough for the next one? If it's really bad, I'll listen to an audiobook or use the Headspace app, and then my brain usually goes back to sleep.
