Does someone have some scientific source on that topic? I couldn't find something linked in the article.

Because you’re doing long-term damage to your brain? Now, it’s possible that you’re not, and the brain can heal itself, but that’s why I try and get enough sleep. It disturbs me to think that the impossibly complex biomechanical machine in my head is slogging through excess waste products to try and crank out acceptable performance.
Most of these studies tend to be focused on temporary effects, including this one. Most of that "damage" can be undone with a good nights sleep. But even if some amount is permanent, so what? Does my brain need to be in mint condition? If the cost of getting more enjoyment out of life is a little brain damage, so be it. I hold no ego about my brain being perfect. Performance is only one aspect of life and not one I s…
I was referring to evidence that chronic sleep deprivation can increase the risk of Alzheimer’s and other dementias by allowing the brain less time to flush out amyloid proteins that can aggregate.

...But everyone’s brain is different, and if you don’t feel your enjoyment of life is being affected, then it’s entirely possible your brain is getting all its maintenance needs met in the time you sleep.
I didn’t mean to sound moralizing or judgmental— these decisions are of course entirely ours to make for ourselves.

If you are X% less productive you will be able to charge X% less for your work, on average, so you would need to work longer hours for the same pay. You might also be shortening your life by not sleeping enough, perhaps by a larger amount than you're gaining by sleeping less. That is clearly the case in the limit of not sleeping at all -- you would shorten your life to a month at best, not to mention that the quality…
> If you are X% less productive you will be able to charge X% less for your work, on average, so you would need to work longer hours for the same pay. That's making the huge assumption that you're willing to constantly seek your maximum pay and that you get paid solely for your measurable productivity output, which is in my experience very rarely the case. More often than not you get paid based on capabilities and re…
>To my knowledge, sleep dep hasn't actually killed people directly like this, they simply start sleeping.
Actually, there is at least one example, surely there are more: http://www.huffingtonpost.com/2012/06/27/man-dies-11-days-no...

About 1.5 years, give or take. I pretty much require 9 hours on a monophasic schedule to feel as sharp.
Yeah, I worry, this only gets rid of tiredeness but not fulfill the whole 8-9 hours of sleep.
From my experience, I'm better rested now than I was before I went bi-phasic.
I personally believe sleep is simply a cleaning cycle for the brain, waiting 16 hours between cleaning cycles may be deleterious.

Actually, studies have shown that hunter-gatherer societies spent much less than 40h/week "working" and had more leisure time than we do. It's just recent history that's an anomaly...
Not only that, but the 40h/week ignores commutes. For some people that's an additional 15h/week. Also hunger-gatherers lived right beside the people they knew. They just had to step outside to meet up with friends to socialize.
> with friends to socialize
Or, sometimes, rival tribes to fight with and kill -- not everything is (necessarily) hunky-dory in every tribal society.

Why is it important that studies have shown a particular result?
Some people feel that humans have evolved over millions of years to do well in hunter-gatherer tribes and we have not genetically adapted yet in 6,000? years of civilization. If we think returning some habits of hunter-gatherer tribes would be beneficial, then we need to know what they are/were and not just wild-ass guess based on the Nobel Savage myth.
Many of the habits of hunter-gatherers would likely be absolutely unacceptable in today's culture. They were likely violently clannish/racist, completely male-dominated, hierarchical based on physical strength and appearance, and believed in gods/supernatural phenomenon.

#67I'm much more interested in why a body needs an amount of sleep, what processes it is conducting, and how you can affect those processes. What happens in the 7th hour that didn't happen in the 6th? If it's a fourth REM cycle, why do we need 4? What does the fourth do that the third didn't? Why do REM cycles take that long? Can you make them take more or less time? Can you determine lack of sleep from a brain scan? Ca…
This article doesn't try to, but this comment section would be a fine place for those smarter than me to drop knowledge bombs on us :D

#68Not a single study or piece of research referenced by the article. "Some professor with a book says..." is not very convincing.
This is not a news article, and is not journalism. This is an advertisement for a book.

#69But do I need to be more productive? It's a tradeoff - I can go home and spend more social time, leisure time and put more personal time into my projects if I sleep less. The 2-3 hours of extra time I get by sleeping like crap allows me to do things I wouldn't otherwise get to do. Productivity couldn't improve these if there's no time left in the day to do them. It costs me at work, I'm sure of it, but it hasn't gott…
> It costs me at work, I'm sure of it, but it hasn't gotten me fired or even significantly prevented me from doing my job, so why would I change it?
That's exactly it, it's a lose-lose. Honestly, I think it's the number one thing I look for when weighing a job offer: if I spend 5 hours a day writing high quality code, will anyone care if I take off after? I'd rather have time to go home, go to the gym, relax, and get 9 hours of sleep. I hate the feeling of just being at the office because I feel like I should. It makes me happier and honestly, over the long-term, my work output is better than when I was working 10 hour days.

#70This is one of the reasons I hate the eight-hour work day. Between that and all of the other shit you have to do in a day (commute, chores, eating, exercise etc.), it seems like there's little to no opportunity to just have a life. I know it sounds like first world problems (people used to work 100 hour weeks), but I think our culture needs to change before we can really put the onus on people to improve their sleepi…
I'm with you all the way!
I hear people talk about optimizing one's day to be more productive and "get more done in your day" so often...but honestly, between work, family responsibilities, working out a little in the gym, getting involved in side projects (either "working on the car", or working on side dev project), maybe some civic community involvement, social visits (the occasional beer with a buddy), etc...it just feels like something has to give...and in my case, its the number of hours of sleep.
Perhaps i'm naive or too idealistic, but will the coming hordes of robots and associated automation help society by giving us all more time to ourselves - either for more/appropriate hours of sleep, or to spend on the activities i noted above? Or...maybe society - or should i say our capitalistic society - will "see" the unused bandwidth of our days made available by these robots, and insert more commitments to "fill our days"?
Sorry, i didn't get enough sleep last night, so am a little cranky. ;-)
