Sleep is very important to me for both health and beauty reasons.

Always the revolutionary, I've recently been wondering whether I might be better off having my time at work be the last 8 hours of my day, rather than the first. Id est, I would sleep from 6pm - 2am, wake up, tend to my personal life, have breakfast and lunch, and then go to work (and have dinner during my lunch break). Since I'm so tired after work, which can lead to wasted time in my personal life, I thought such a schedule would properly prioritize and value my personal life over my working life. Plus, it would allow me to sleep for over 8 hours and still get to work on time, should I so desire.

The problem with this proposal is that the rest of the world operates on a different clock, so accomplishing any tasks that involve other people could be hard. The internet solves some of that (I can go shopping anytime), and there is a 24-hour eatery in my backyard, but there still could be some monkey wrenches.

Choice Excerpts from "The Sleep-Industrial Complex:" A [long-ass]New York Times Magazine Article

"Sleep hygiene," a concept discussed in the below article, really appeals to me. Like dental hygiene, I aspire to have good sleep hygiene. The article also critically discusses sleep from a historical/cross-cultural perspective.

About 33% of it focuses on the mattress industry, and 10% focuses on pharmaceuticals. I didn't find those parts to be as relevant, so I cut them out.

Here 'tis:

Our misunderstandings about sleep have been centuries in the making. As has already happened in the food and nutrition businesses, some sectors of our new sleep-industrial complex will surely find it profitable to clear up our confusion, while others will simply exploit it. But as mattress companies and sleeping-pill makers both barrel into the marketplace to sell us a good night’s sleep, it’s tough to know where in the jumble of science and storytelling the truth about sleep lies.

All good nights of sleep are alike. Each miserable night of sleep is miserable in its own way. You either close your eyes and, many hours later, open them, or you endure an idiosyncratic epic of waiting, trying, failing, irritation, self-sabotage and despair, then stand up at sunrise racked with war stories you don’t have the energy to tell.

Sleep research is a young field and still doesn’t have a definitive picture of what “normal” sleep is, making discussions of abnormal sleep imprecise. The National Institutes of Health can define insomnia only very broadly, as “complaints of disturbed sleep in the presence of adequate opportunity and circumstance for sleep.” Insomnia can be transient — a few off nights — or horrifically chronic. Complaints may be about difficulty falling asleep or about waking up during the night. But it’s hard to know exactly what those complaints should be judged against. Nor has research determined which objective measures — total time slept, percentage of time spent in the various stages of sleep, etc. — correlate to a person’s subjective feeling of having slept well or poorly. Some people whose sleep looks normal in the lab complain bitterly; some whose sleep looks terrible never do.

Even something as empirical-seeming as how long we sleep becomes problematic. In studies, insomniacs almost invariably overestimate how long it took them to fall asleep and underestimate how long they slept; in one, more than a third of the participants consistently thought they’d slept at least an hour less than their brain-wave activity indicated. Yet in a way, this hardly matters. Wallace Mendelson, past president of the Sleep Research Society, explained to me, “When a patient comes to a doctor, he doesn’t say, ‘I’m here to see you because my EEG shows an insufficient number of minutes of sleep.’ He comes to you saying: ‘I don’t feel like I’m getting enough. I’m tired.’ ” Thus, while insomnia is frequently linked to another, distinct physiological disease or disorder, its diagnosis and treatment often remain, much like pain, locked in the realm of our own inscrutable reports.

Fewer than half of Americans say they get a good night’s sleep every night or almost every night, according to a 2005 poll by the National Sleep Foundation. The N.S.F. is a nonprofit largely financed by the pharmaceutical industry and one of many groups — including the American Academy of Sleep Medicine and the Better Sleep Council, a nonprofit supported by the mattress industry — that have pushed the value of sleep, and the perils of sleep deprivation and disorders, into public view. (You can mark the change in seasons with their press releases. End of summer: “From Zzzs to A’s: Healthy Sleep Is Key for Back-to-School Success.” Daylight Savings Time: “Fall Back Into Bed and Catch Up on Your Sleep.”)

Some of America’s dissatisfaction likely boils down to poor “sleep hygiene” — basic bad habits like not keeping a regular bedtime; overconsumption of alcohol or coffee; or winding ourselves up with work or television before bed. There is a sometimes-stunning failure to see sleep’s cause-and-effect relationship to what we do while awake. One therapist told me he cured a man’s insomnia by suggesting he stop eating spicy Indian curry late at night. Bils says, “Most sleep problems are self-inflicted by sleepers not knowing how to sleep.” Moreover, doctors have long warned that Americans are suffering from self-caused sleep deprivation without even realizing it. The most damaging and persistent delusion we’ve acquired about sleep is that the vital human function is optional. As one psychologist puts it, “You don’t have people walking around figuring out how to get by on less air.”

The story of our ruined sleep, in virtually every telling I’ve heard, begins with Thomas Edison: electric light destroyed the sanctity of night. Given more to do and more opportunity to do it, we gave sleep shorter and shorter shrift. But the sleep that we’re now trying to reclaim may never have been ours to begin with. “It’s a myth,” A. Roger Ekirch, a professor of history at Virginia Tech, told me. “And it’s a myth that even some sleep experts today have bought into.”
. . .
More surprising still, Ekirch reports that for many centuries, and perhaps back to Homer, Western society slept in two shifts. People went to sleep, got up in the middle of the night for an hour or so, and then went to sleep again. Thus night — divided into a “first sleep” and “second sleep” — also included a curious intermission. “There was an extraordinary level of activity,” Ekirch told me. People got up and tended to their animals or did housekeeping. Others had sex or just lay in bed thinking, smoking a pipe, or gossiping with bedfellows. Benjamin Franklin took “cold-air baths,” reading naked in a chair.

Our conception of sleep as an unbroken block is so innate that it can seem inconceivable that people only two centuries ago should have experienced it so differently. Yet in an experiment at the National Institutes of Health a decade ago, men kept on a schedule of 10 hours of light and 14 hours of darkness — mimicking the duration of day and night during winter — fell into the same, segmented pattern. They began sleeping in two distinct, roughly four-hour stretches, with one to three hours of somnolence — just calmly lying there — in between. Some sleep disorders, namely waking up in the middle of the night and not being able to fall asleep again, “may simply be this traditional pattern, this normal pattern, reasserting itself,” Ekirch told me. “It’s the seamless sleep that we aspire to that’s the anomaly, the creation of the modern world.”

In fact, many contemporary, nonindustrialized cultures contentedly pass portions of the night in the same state of somnolence, says Carol Worthman, an anthropologist at Emory University who is one of the first to look at how other societies sleep. Sleep and wakefulness are rarely seen as an either/or, but rather as two ends of a wide spectrum, and people are far more at peace with the fluidity in between. Among the Efe in Zaire, and the !Kung in Botswana, for example, someone who wakes up in the middle of the night and cannot sleep “may begin to hum, or go out and play the thumb piano,” Worthman and a colleague have written. Others might wake up and join in. “Music or even a dance may get going.”
--
Worthman says, “In our culture, quality sleep is going into a dark room that is totally quiet, lying down, falling asleep, doing that for eight hours, and then getting up again.” She calls it the “lie down and die” model. “But that is not how much of the world has slept in the past or even sleeps today.” In some cultures sleep is more social, with crowds crammed together on little or no bedding, limbs entangled, while a steady traffic comes and goes. And while it all sounds unbearable, Worthman notes that science has never looked empirically at whether our more sophisticated arrangements actually benefit us. For children, learning to sleep amid all that stimulation may actually have developmental advantages.

Still, we can’t afford the same equanimity about not sleeping through the night as the Efe and !Kung; the flipside is that men and women in those cultures are content to pull a cloth over their faces and doze off during the day if necessary. Our peculiar preference for one well-organized hunk of sleep likely evolved as a corollary to our expectation of uninterrupted wakefulness during the day — as our lives came to be governed by a single, stringent clock. Eluned Summers-Bremner, author of the forthcoming “Insomnia: A Cultural History,” explains that in the 18th century, “we start overvaluing our waking time, and come to see our sleeping time only as a way to support our waking time.” Consequently, we begin trying to streamline sleep, to get it done more economically: “We should lie down and go out right away so we can get up and get to the day right away.” She describes insomniacs as having a ruthless ambition to do just this, wanting to administer sleep as an efficiency expert normalizes the action in a factory. Certainly all of us, after a protracted failure to fall asleep for whatever reason, have turned solemnly to our alarm clocks and performed that desperate arithmetic: If I fall asleep right now, I can still get four hours.

Nevertheless, while it may be at odds with our history and even our biology, lie-down-and-die is the only practical model for our lifestyle. Unless we overhaul society to tolerate all schedules and degrees of sleepiness and attentiveness, we are stuck with that ideal. Perhaps the real problem is that we still haven’t come to terms with the unavoidable imperfection of this state of affairs.
Electric light didn’t obliterate nighttime so much as reinvent it. Our power to toggle between light and dark encouraged us to see night as an empty antithesis to day — an unbroken nothing-time that begins the instant we flip off the switch. And this significantly reshaped and rigidified our expectations of how we ought to be spending it. All of this leaves us — regardless of the circumstances or how poor our sleep hygiene is — insisting that we go out, and stay out, like a light.

Our expectation of perfect sleep may not always be biologically feasible . . . it’s not uncommon to discover that a particularly implacable case of insomnia snowballed out of a single stretch of poor sleep — even one with a clear, unavoidable cause, like stress over a new job. While most people eventually shrug off their trouble, the insomniac “forgets what brought about the sleeping problem in the first place,” Morin said. “They worry about not sleeping and how it will impact their daytime functioning, and they start to do things that make sleep more difficult.”

They take naps, throwing their schedule out of whack. Or they become too determined — Morin described patients taking a bath or getting into their pajamas at 7 o’clock, “just to get ready” — and that anticipation turns into performance anxiety. Lying there, they may monitor their progress too vigilantly or worry about the ramifications the next day of not falling asleep right away. This can produce a physiological reaction. Body temperature and blood pressure rise. Metabolism speeds up. Heart rate and brain waves quicken. In other words, the body can respond to the threat of not getting a good night’s sleep the same way it does to most threats: by becoming hyperaroused. “It’s a vicious cycle,” Morin said.

. . . But whatever its cause, this feedback loop of agony, effort and failure plays out like an escalation of the kind of self-sabotage we’ve all probably experienced when we felt pressure to sleep well and be sharp the next day. “Most of the beliefs these people develop and strategies they employ are very logical and sensible,” Jack Edinger, a psychologist at Duke University and the V.A. Medical Center in Durham, North Carolina, told me. But “unlike most things in life where, the harder you try, the better you do, with sleep the harder you try the worse you do.

Edinger and Morin have been influential in the use of cognitive behavioral therapy, or C.B.T., to treat chronic insomnia. Studies have arguably shown it to be the most successful treatment for the problem and an astonishingly effective method of weaning insomniacs from sleeping pills — even those who have taken them every night for decades. C.B.T. Therapists work to establish good sleep habits but also to rewrite an insomniac’s unhelpful beliefs about sleep. One of the most typical and debilitating ones, Morin explained, is “that eight hours of solid, uninterrupted sleep is a must every night — and otherwise, without it, you can’t function during the day.” Fixating on that as a requirement only undoes a person. Besides, Morin added, a universal need for eight hours is simply “untrue.”
