Co-founder and editor in chief of The Huffington Post Arianna Huffington shows how our cultural dismissal of sleep as time wasted compromises our health and our decision-making and undermines our work lives, our personal livesand even our sex lives in this New York Times bestseller.
We are in the midst of a sleep deprivation crisis, with profound consequences to our health, our job performance, our relationships and our happiness. What we need is nothing short of a sleep revolution: only by renewing our relationship with sleep can we take back control of our lives.
In The Sleep Revolution, Arianna explores all the latest science on what exactly is going on while we sleep and dream. She takes on the sleeping pill industry, and all the ways our addiction to technology disrupts our sleep. She also offers a range of recommendations and tips from leading scientists on how we can get better and more restorative sleep, and harness its incredible power.
The result is a sweeping, scientifically rigorous, and deeply personal exploration of sleep from all angles, from the history of sleep, to the role of dreams in our lives, to the consequences of sleep deprivation, and the new golden age of sleep science that reveals the vital role sleep plays in our every waking moment and every aspect of our healthfrom weight gain, diabetes, and heart disease to cancer and Alzheimer’s.
In today's fast-paced, always-connected, perpetually-harried and sleep-deprived world, our need for a good night’s sleep is more importantand elusivethan ever. The Sleep Revolution both sounds the alarm on our worldwide sleep crisis and provides a detailed road map to the great sleep awakening that can help transform our lives, our communities, and our world.

OUR CURRENT SLEEP CRISIS
Sarvshreshth Gupta was a first-year analyst at Goldman Sachs in San Francisco in 2015. Overwhelmed by the hundred-hour workweeks, he decided to leave the bank in March. He soon returned, though whether this was a result of social or self-inflicted pressure is still unclear. A week later, he called his father at 2:40 a.m. saying he hadn’t slept in two days. He said he had a presentation to complete and a morning meeting to prepare for, and was alone in the office. His father insisted he go home, and Gupta replied that he would stay at work just a bit longer. A few hours later, he was found dead on the street outside his home. He had jumped from his high-rise building.
Death from overwork has its own word in Japanese (karoshi), in Chinese (guolaosi), and in Korean (gwarosa). No such word exists in English, but the casualties are all around us. And though this is an extreme example of the consequences of not getting enough sleep, sleep deprivation has become an epidemic.
It is a specter haunting the industrialized world. Simply put: we don’t get enough sleep. And it’s a much bigger problem—with much higher stakes—than many of us realize. Both our daytime hours and our nighttime hours are under assault as never before. As the amount of things we need to cram into each day has increased, the value of our awake time has skyrocketed. Benjamin Franklin’s “Time is money!” has become a corporate-world mantra. And this has come at the expense of our time asleep, which since the dawn of the Industrial Revolution we have treated like some dull, distant relative we visit only reluctantly and out of obligation, for as short a time as we can manage.
But scientists are resoundingly confirming what our ancestors knew instinctively: that our sleep is not empty time. Sleep is a time of intense neurological activity—a rich time of renewal, memory consolidation, brain and neurochemical cleansing, and cognitive maintenance. Properly appraised, our sleeping time is as valuable a commodity as the time we are awake. In fact, getting the right amount of sleep enhances the quality of every minute we spend with our eyes open.
But today much of our society is still operating under the collective delusion that sleep is simply time lost to other pursuits, that it can be endlessly appropriated at will to satisfy our increasingly busy lives and overstuffed to-do lists. We see this delusion reflected in the phrase “I’ll sleep when I’m dead” has flooded popular consciousness, including a hit Bon Jovi song, an album by the late rocker Warren Zevon, and a crime film starring Clive Owen. Everywhere you turn, sleep deprivation is glamorized and celebrated: “You snooze, you lose.” The phrase “catch a few z’s” is telling: the last letter of the alphabet used to represent that last thing on our culture’s shared priority list. The combination of a deeply misguided definition of what it means to be successful in today’s world—that it can come only through burnout and stress—along with the distractions and temptations of a 24/7 wired world, has imperiled our sleep as never before.
I experienced firsthand the high price we’re paying for cheating sleep when I collapsed from exhaustion, and it pains me to see dear friends (and strangers) go through the same struggle. Rajiv Joshi is the managing director of the B Team—a nonprofit on whose board I serve, founded by Richard Branson and Jochen Zeitz to help move business beyond profit as the only metric of success. In June 2015, he had a seizure at age thirty-one during a B Team meeting in Bellagio, Italy, collapsing from exhaustion and sleep deprivation. Unable to walk, he spent eight days in a hospital in Bellagio and weeks after in physical therapy. In talking with medical experts, he learned that we all have a “seizure threshold,” and when we don’t take time to properly rest, we move closer and closer to it. Rajiv had crossed his threshold and fallen off the cliff. “The struggle for a more just and sustainable world,” he told me when he was back at work, “is a marathon, not a sprint, and we can’t forget that it starts at home with personal sustainability.”
According to a recent Gallup poll, 40 percent of all American adults are sleep-deprived, clocking significantly less than the recommended minimum seven hours of sleep per night. Getting enough sleep, says Dr. Judith Owens, the director of the Center for Pediatric Sleep Disorders at Boston Children’s Hospital, is “just as important as good nutrition, physical activity, and wearing your seat belt.” But most people hugely underestimate their need for sleep. That’s why sleep, says Dr. Michael Roizen, the chief wellness officer of the Cleveland Clinic, “is our most underrated health habit.” A National Sleep Foundation report backs this up: two-thirds of us are not getting enough sleep on weeknights.
The crisis is global. In 2011, 32 percent of people surveyed in the United Kingdom said they had averaged less than seven hours of sleep a night in the previous six months. By 2014 that number had rocketed up to 60 percent. In 2013, more than a third of Germans and tw-thirds of Japanese surveyed said they do not get sufficient sleep on weeknights. In fact, the Japanese have a term, inemuri, which roughly translates as “to be asleep while present”—that is, to be so exhausted that you fall asleep in the middle of a meeting. This has been praised as a sign of dedication and hard work—but it is actually another symptom of the sleep crisis we are finally confronting.
The wearable-device company Jawbone collects sleep data from thousands of people wearing its UP activity trackers. As a result, we now have a record of the cities that get the least amount of sleep. Tokyo residents sleep a dangerously low 5 hours and 45 minutes a night. Seoul clocks in at 6 hours and 3 minutes; Dubai, 6 hours and 13 minutes; Singapore, 6 hours and 27 minutes; Hong Kong, 6 hours and 29 minutes; and Las Vegas, 6 hours and 32 minutes. When you’re getting less sleep than Las Vegas, you have a problem.
Of course, much of this can be laid at the feet of work—or, more broadly, how we define work, which is colored by how we define success and what’s important in our lives. The unquestioning belief that work should always have the top claim on our time has been a costly one. And it has gotten worse, as technology has allowed a growing number of us to carry our work with us—in our pockets and purses in the form of our phones—wherever we go.
Our houses, our bedrooms—even our beds—are littered with beeping, vibrating, flashing screens. It’s the never-ending possibility of connecting—with friends, with strangers, with the entire world, with every TV show or movie ever made—with just the press of a button that is, not surprisingly, addictive. Humans are social creatures—we’re hardwired to connect. Even when we’re not actually connecting digitally, we’re in a constant state of heightened anticipation. And always being in this state doesn’t exactly put us in the right frame of mind to wind down when it’s time to sleep. Though we don’t give much thought into how we put ourselves to bed, we have little resting places and refueling shrines all over our houses, like little doll beds, where our technology can recharge, even if we can’t.
Being perpetually wired is now considered a prerequisite for success, as Alan Derickson writes in Dangerously Sleepy: “Sleep deprivation now resides within a repertoire of practices deemed essential to survival in a globally competitive world. More so than in the time of Thomas Edison, depriving oneself of necessary rest or denying it to those under one’s control is considered necessary to success in a 24/7/365 society. Americans have a stronger ideological rationale than ever to distrust any sort of dormancy.”
And Americans are anything but dormant. From 1990 to 2000, American workers added the equivalent of another full workweek to their year. A 2014 survey by Skift, a travel website, showed that more than 40 percent of Americans had not taken a single vacation day that year. Much of that added work time has come at the expense of sleep. Dr. Charles Czeisler, the head of the Division of Sleep and Circadian Disorders at Brigham and Women’s Hospital in Boston, estimates that in the past fifty years our sleep on work nights has dropped from eight and a half hours to just under seven. Thirty percent of employed Americans now report getting six hours of sleep or less per night, and nearly 70 percent describe their sleep as insufficient. Getting by on less than six hours of sleep is one of the biggest factors in job burnout.
And for far too many people in the world, the vicious cycle of financial deprivation also feeds into the vicious cycle of sleep deprivation. If you’re working two or three jobs and struggling to make ends meet, “get more sleep” is probably not going to be near the top of your priorities list. As in the case of health care, access to sleep is not evenly—or fairly—distributed. Sleep is another casualty of inequality. A 2013 study from the University of Chicago found that “lower socio-economic position was associated with poorer subjective sleep quality, increased sleepiness and/or increased sleep complaints.” But the paradox here is that the more challenging our circumstances, the more imperative it is to take whatever steps we can to tap in to our resilience to help us withstand and overcome the challenges we face. There’s a reason we’re told on airplanes to “secure your own mask first.”
Where we live can also affect our sleep. “I have never seen a study that hasn’t shown a direct association between neighborhood quality and sleep quality,” said Lauren Hale, a Stony Brook University professor of preventive medicine. If you’re living in a neighborhood with gang warfare and random acts of violence, sleep will inevitably suffer—yet another example of sleep deprivation’s connection with deeper social problems.
THE COST OF LOST SLEEP
It is industrialization, for all its benefits, that has exacerbated our flawed relationship with sleep on such a massive scale. We sacrifice sleep in the name of productivity, but, ironically, our loss of sleep, despite the extra hours we put in at work, adds up to more than eleven days of lost productivity per year per worker, or about $2,280. This results in a total annual cost of sleep deprivation to the US economy of more than $63 billion, in the form of absenteeism and presenteeism (when employees are present at work physically but not really mentally focused). “Americans are not missing work because of insomnia,” said Harvard Medical School professor Ronald C. Kessler. “They are still going to their jobs, but they’re accomplishing less because they’re tired. In an information-based economy, it’s difficult to find a condition that has a greater effect on productivity.”
Sleep disorders cost Australia more than $5 billion a year in health care and indirect costs. And “reduction in life quality” added costs equivalent to a whopping $31.4 billion a year. A report, aptly titled “Re-Awakening Australia,” linked lack of sleep with lost productivity and driving and workplace accidents. In the United Kingdom, a survey showed that one in five employees had recently missed work or come in late because of sleep deprivation. The researchers estimated that this is equivalent to a loss of more than 47 million hours of work per year, or a £453 million loss in productivity. And almost a third of all UK employees reported feeling tired every morning. Yet, though awareness is spreading, few companies have given sleep the priority it deserves, considering its effects on their bottom line. In Canada, 26 percent of the workforce reported having called in sick because of sleep deprivation. And nearly two-thirds of Canadian adults report feeling tired “most of the time.”
It turns out that women need more sleep than men, so the lack of sleep has even more negative mental and physical effects on them. Duke Medical Center researchers found that women are at a greater risk for heart disease, Type 2 diabetes, and depression. “We found that for women, poor sleep is strongly associated with high levels of psychological distress, and greater feelings of hostility, depression and anger,” said Edward Suarez, the lead author of the study. “In contrast, these feelings were not associated with the same degree of sleep disruption in men.”
As women have entered the workplace—a workplace created in large measure by men, which uses our willingness to work long hours until we ultimately burn out as a proxy for commitment and dedication—they are still stuck with the heavy lifting when it comes to housework. The upshot is that women end up making even more withdrawals from their sleep bank. “They have so many commitments, and sleep starts to get low on the totem pole,” says Michael Breus, the author of Beauty Sleep. “They may know that sleep should be a priority, but then, you know, they’ve just got to get that last thing done. And that’s when it starts to get bad.”
According to Dr. William Dement, the founder of the Stanford Sleep Disorders Clinic (the first of its kind), working mothers who have young children at home have seen an additional 241 hours of work and commuting time added to their lives annually since 1969.
Sarah Bunton, a mother and cognitive-skills trainer, described her experience on The Huffington Post: “Do you ever have one of those days where you want to hit pause? Let me rephrase: do you ever have a day where you don’t want to hit pause? . . . There really isn’t an end of the day for most moms, working or otherwise. There’s usually not a beginning, either, just a continuation of whatever chaos preceded the momentary silence . . . Mommy wants a nap.”
“Let’s face it, women today are tired. Done. Cooked. Fried,” wrote Karen Brody, founder of the meditation program Bold Tranquility. “I coach busy women and this is what they tell me all the time: ‘I spent years getting educated and now I don’t have any energy to work.’ ”
Dr. Frank Lipman, the founder of the Eleven Eleven Wellness Center in New York, sees so many patients who are sleep-deprived and exhausted that he came up with his own term for them. “I started calling these patients ‘spent,’ because that was how they seemed to me,” he writes. He compares this to his time working in rural South Africa: “There I saw many diseases arising from poverty and malnutrition but I didn’t see anyone who was ‘spent,’ as I do today in New York.”
The world is too much with us; late and soon,
Getting and spending, we lay waste our powers . . .
For this, for everything, we are out of tune.
—William Wordsworth, “The World Is Too Much with Us”
