Another thinker concerned with the 24/7 lifestyle is Jonathan Crary, a distinguished art historian at Columbia University who has just published a book titled, well, 24/7. Crary sees sleep as one of the few remaining areas that have resisted colonization by the ominous forces of that faceless chimera, neoliberalism. “The huge portion of our lives that we spend asleep, freed from a morass of simulated needs, subsists as one of the great human affronts to the voraciousness of contemporary capitalism,” he writes. (Yes, Crary's prose can be sleep-inducing. In his defense, it's a book about the virtues of sleep!)
Many fascinating anecdotes and statistics follow. The Pentagon, always in the vanguard of innovation, is spending millions to free soldiers from the burden of sleep altogether. We are almost there anyway: According to Crary, today the average North American adult sleeps approximately six and a half hours a night, compared with eight hours a generation ago and 10 hours a century ago. What's not to like about Crary's message? Yes, even you can subvert modern capitalism: by sleeping more! #Occupythebedroom.
Oddly, Crary says nothing about lifehacking—a glaring omission, when one of its many branches, “sleep hacking,” is specifically dedicated to tinkering with one's sleep. A common goal for many “sleep hackers” is to spend less time in a phase known as “light sleep,” shifting it to high-quality phrases such as “deep sleep” or “rapid eye movement sleep.” (The staying-awake phase right before you fall asleep is prized by Crary but apparently dreaded by many “sleep hackers.”)
Sleephackers go to bed with sensors on their wrists and foreheads and maintain detailed electronic sleep diaries, which they often share online. To shift between sleep phases, sleephackers experiment with various diets, room and body temperatures, and kinds of pre-sleep physical exercise. For example, Ferriss also wrote The 4-Hour Body, in which he offers plenty of advice on getting high-quality sleep—and faster. A typical nugget reads: “Consumed within three hours of getting under the sheets, meals of at least 800 milligrams of cholesterol (four or more large whole eggs) and 40 grams of protein produced dramatically faster time-to-sleep scores than meals of lower volume or lower protein and fat.”
Crary is correct to note that “within the globalist neoliberal paradigm, sleeping is for losers”—especially if Timothy Ferriss, munching eggs on his way to the bedroom, is the paragon of success—but he seems unaware of just how quantification and self-tracking, often in their most aggressive, Taylorist mode, have already invaded our bedrooms. This space is no longer as pristine as Crary claims. Researching this column, I stumbled upon a blog post—a typical one, it turned out—by one of the keen practitioners of sleephacking. It features as many graphs and percentage points as a PowerPoint from McKinsey. Reflecting on a sleep experience that totaled 7.27 hours—of which 52 percent was spent on light sleep, 29 percent on REM sleep, and 19 percent on deep sleep—the author calls this “inefficient sleep” and complains that it “contains a lot of wasted time.”
At first—as is the case with most lifehacking endeavors—sleephacking sounds wonderful: Why not improve the quality of your sleep with sophisticated sensors and scrupulous tracking? After all, most of us have accepted the comfort that comes with fancy mattresses. The problem— as the title of Ferriss's The 4-Hour Body indicates— is that once you accept the argument that “quality sleep is not about quantity,” it is tempting to use that knowledge to cut on out sleep altogether. And once the tools and techniques for sleephacking are cheap and universally accessible, how could you explain your irresponsible insistence on sleeping longer rather than, well, “better” either to yourself or to your boss? Why have six hours of mediocre sleep if you can get the same numbers from three hours of good sleep?
Time for a lifehacking revolution, perhaps? What we want, to paraphrase Marx, is to “lifehack in the morning—in order to nap in the afternoon and criticize after dinner.” What we get right now—to “lifehack the morning—in order to skip naps in the afternoon and work after dinner”—is a raw deal. “Get busy—or get bed to bed”—now, that is a fitting slogan for a modern-day revolutionary movement.
