I almost never get 8 hours of sleep any more.

And I almost never set an alarm.

Which means I feel really, really tired most of the time, because I need at least 9 hours to be fully rested.

I don't think I've gotten enough sleep on a regular basis since I worked a 4-midnight shift.  I blacked out my windows so it would be completely dark in my bedroom all the time, and I usually went to bed around 4-5 am.

Pharmdawg: CEOs, politicians and other high achievers (we're looking at you, Hillary Clinton) may only need an insane three to five hours of sleep a night

That explains a great deal about their decisions.


I know, right? How much sleep do you need to get in order to marry an ambitious, powerful man and then ride his coat-tails?

taurusowner: GDubDub: I'm fed up with the people who "only sleep [some number way under 8] hours a night and feel great!" types.

They are like vegans.
Or gluten-free people.
Or people who don't own TVs.


Think the new person you just meet might [be vegan]|[be gluten-free]|[not own a TV]|[only sleep 3 hours a night and feel great]?  Don't worry, you'll know in 5 minutes.

Or people who do CrossFit. Don't get me wrong, CrossFit is a great workout program (though some gyms emphasize the competitive aspects too much to the detriment of safety) and I have tried it myself. But anytime you get a group of people together who are into exercise, if there's a CrossFit zealot around he will make his presence known quickly. It makes me wonder if when you start going to a gym for a decent amount of time they don't actually tell the members to go out a proselytize.


Marathon runners too.  It's like the old joke is: How can you tell if someone has run a marathon?  Don't worry, they'll tell you.
 
2014-07-23 07:59:10 AM

hubiestubert: I generally run my best on 5-6 hours. I broke habit, and stayed up last weekend on a marathon reading session to finish a damn book, and was up until 6am or so, and wound up sleeping until nearly 7:45pm, and given the extended sunlight, didn't realize how late it was until I checked the clock after getting some coffee. I went to bed again at my usual 1am or so, and was up by 6am the next day.

I sleep as long as my body deems fit. Sometimes it's longer, sometimes it's less. There's enough to do that if I do wake up, it's not some mass tragedy that I "lost" time somewhere. And if I sleep in, that's not exactly a terrible thing either--though at this point, 7am is considered "sleeping in"...


heh, what book were you reading? I must know!

sleep activity of about 450 elderly women

Well, that explains the findings: all of your cited research was done with biased samples. You shouldn't apply it to real-world situations.

Farking journalists.

8 hours is about the norm for me. I have to get up at 4 every morning so I am usually asleep by 8-ish on weekdays. What sucks though is my circadian clock is now set for that schedule so on weekends no matter how late I stay up or how much I let loose I wake up at 5 in the morning. I'd murder to be able to sleep in until like, noon, just once.
 
2014-07-23 08:00:23 AM
Sleep is supposed to be at the body's need, not crammed into whatever arbitrarily-imposed schedule that some sadistic, puritanical overlords would put it in. Not everyone is meant to sleep the same way, in the same amount or with the same clockwork regularity as has been supposed and even enforced by tradition. Other cultures seem to understand this, but in the U.S., and much of the West since the Industrial Revolution, not so much. Once, believe it or not, it was commonly accepted that there were two sleep periods per night, and sometimes a Siesta in the afternoon. The total amount of sleep wasn't necessarily much longer than the "8 straight hours", but it was more organic, and probably that allowed for better regulation of things like blood pressure, metabolism and hydration and at the cellular level meant better housekeeping in the lymphatic and endocrine systems which can prevent a host of diseases. And yeah, if you're an adult and need to sleep for an overly-long time all the time, you probably have something wrong that really should be addressed medically.


There was a time when I slept well, with vivid, golden dreams that lingered fully long after waking.

But now -- Don't look at me that way! -- In my old age, infirmity, apnea and insomnia, I sleep the way old men pee; sometimes all at once, sometimes drop by drop. ...I sleep erratically. Often enormously. And my dreams evaporate utterly upon waking.

...Like a vampire meeting the sunrise.

As someone who suffered from total insomnia for a span of a couple months thanks to some farked up hormones, that first night I was able to lie down and not get immediately jerked wide awake by overactive adrenals was freakin' glorious.

In college I could sleep 12 hours a day easy.  No matter how late into the afternoon I slept, I'd have to force myself to get up like I'd been drugged.  The drugs probably didn't help but still.  I had one incident where, at around 1pm, my roommate came in and woke me up.  I tried to get up but I couldn't move or speak...I could see him walking around but I was paralyzed...scared the crap out of me.

Yep. Wait till they're teenagers and riding a motorcycle, backpacking solo across Central America, or any of those other wonderful life experiences you may have had yourself at that age, and you'll realize that there will always be phases of a parent's life when it's more difficult to sleep than usual.

Dadoody: Why do we even need sleep anyways?

Would be great if we were awake our whole lives.


Well, you'd save on bedroom furniture and have extra space for that music room you've always wanted, anyway.

Y'know, it'd be even better if we only had to eat and poop once a fortnight, too. Also if we could go months without water or revive from being frozen solid or desiccated. Having skin that could regenerate entirely and slough off old, damaged sections would be good. Growing back entire body parts that had been severed and having the option of asexual reproduction via fragmentation would be cool, too. Having prehensile feet would be good, but only if it didn't make it more difficult to walk. And a prehensile penis could help, especially when you've got two hands full of bags of groceries and need to fish out your keys to unlock your car or when you're shampooing your hair and need to adjust the shower temperature. Having a full set of new teeth grow in every ten or fifteen years, having eyes with reflective and nictitating membranes, the ability to grow extra rods and cones or re-grow entire eyes, and visual pre-processors behind the retina instead of long optic nerves would be good. Also, being able to store vast amounts of oxygen in big muscles so holding one's breath for an hour was no problem. Oh, and bird-like lungs that allow for circular rather than tidal breathing. But no gills. Gills are gross and often get parasites and junk stuck in them.

I am an insomniac, and the most I ever sleep at a time is about 5 hours.  I also can't sleep when I know it's light out, even when I'm sick and need the bedrest.  On the other hand, although I don't sleep long, I do sleep deep, and that's gotta count for something, right?

But everybody knows that before the Industrial Revolution, human life expectancy was about 38 years, and so this can't possibly be true because people died way younger than we do now.

Well, if you click the link to the study in TFA and read the abstract, it says:

"controlling simultaneously for demographics, habits, health factors, and use of various medications."

so yeah, they thought of that one.

Correlation != causation.

Maybe people with underlying health issues (even minor ones) need more sleep. Thus people who sleep more also have a higher rate of issues.

opiumpoopy: Lsherm: I absolutely cannot stand correlation "studies," especially ones that require disclaimers like this in the articles describing them:  Still, doctors caution against scaring folks away from sleeping longer, pointing out that self-reported sleeping patterns from the various studies could be inaccurate, and that, depending on factors including age, state of health and genetics, optimal sleep time can vary with each individual.

I know! The whole field of epidemiology kicked off in the 1960s with a correlation suggesting smoking was bad for you.

What a load of rubbish that turned out to be!


Earlier than that. Before germ theory, there was a high incidence of new mothers dying if the doctor had been messing with corpses before attending a birth. So hand washing led to fewer mothers dying. They figured out it was bacteria much later.

Obviously you can't, but self-reported health is different from having a diagnosis. I doubt that in studies of hundreds of thousands of people that really creates a bias. Nonetheless, I'm merely pointing out that OPs suggestion that "because sick people are more tired" is clearly something the CDC and other researchers have considered and tried to account for.

I have always been an 8+ hour person, no matter what. Anything less than 8 and my brain would not function well all day. When i was at my most fit, I was sleeping 8-9 hours a night and regularly woke up at 5:30 with or without an alarm so I could work out before work. When I was ill with what turned out to be anemia and T2 diabetes, I was sleeping closer to 10 hours a night and needed an alarm to wake up.

BTW: my family have all been long sleepers and my grandparents average age at death was 91 (one grandfather threw off the average by drinking himself to death at 78) and my great grandparents' average was 86. My father died at 79 but Mom is still going strong at 94.

I think the point we are missing here is you should go to sleep when you get tired and wake up when you feel like it. All of this getting up because an alarm goes off because you have to be at some job is what's killing everybody.
