Lights Out Used to Be Enough. Now We've Turned Sleep Into a Second Job.

Lights Out Used to Be Enough. Now We've Turned Sleep Into a Second Job.

At some point in the recent past — hard to pin down exactly, but somewhere in the mid-2010s feels right — going to bed stopped being something you just did and became something you had to prepare for. There's the wind-down routine. The blue light blocking glasses. The white noise machine. The weighted blanket. The magnesium supplement. The sleep tracking app that will tell you in the morning, with the authority of a disappointed coach, that your deep sleep was suboptimal and your resting heart rate was elevated.

Your grandmother, who slept eight hours every night until she was ninety-two, did none of these things. She just turned off the light.

Sleep Before It Became a Lifestyle Category

For most of American history, sleep was treated the way breathing was treated: as something the body handled on its own, without much human supervision. You got tired. You went to bed. You woke up. If you slept badly for a few nights, you chalked it up to stress or too much coffee and waited for it to resolve. The idea that sleep required optimization, ritual, and consumer products would have struck most mid-century Americans as genuinely bizarre.

This wasn't because earlier generations were sleeping perfectly. Insomnia has existed as long as humans have. But it was largely treated as either a temporary annoyance or a medical problem serious enough to warrant a doctor's visit — not a lifestyle challenge requiring a thirty-step evening protocol and a subscription app.

The bedroom itself reflected this simplicity. A mattress, a pillow, maybe a box fan for white noise in the summer. Alarm clocks were analog. The closest thing to a sleep supplement was warm milk or, for some households, a small glass of whiskey. Neither came with dosage instructions.

How Sleep Got Medicalized — Then Monetized

The clinical study of sleep is actually older than most people realize. Sleep research began in earnest in the 1950s when scientists identified REM sleep and started mapping the sleep cycle. By the 1970s and 80s, sleep disorders like sleep apnea and narcolepsy were being formally diagnosed and treated. This was genuinely important medicine — sleep apnea, left untreated, carries serious cardiovascular risks.

But the leap from clinical sleep medicine to consumer sleep culture happened much later, and it happened fast.

The fitness tracker boom of the early 2010s was the accelerant. Devices like the original Fitbit gave everyday people access to data about their own bodies — steps, heart rate, and eventually sleep. The sleep data was crude by clinical standards, but it was data, and Americans have always loved data about themselves. Suddenly, millions of people who had never thought much about their sleep architecture were staring at charts showing their light sleep versus deep sleep versus REM, and finding reasons to be concerned.

The supplement industry was watching. Melatonin sales, already growing, exploded. New products entered the market: magnesium glycinate, L-theanine, ashwagandha, GABA. Sleep gummies became a staple of every pharmacy end cap. By 2023, the global sleep economy — supplements, devices, apps, mattresses, and sleep coaching services — was valued at well over $80 billion. The United States accounted for a substantial portion of that figure.

The Paradox Nobody Wants to Talk About

Here's where things get genuinely strange. Despite all of this investment — the technology, the supplements, the content, the coaching — Americans are not sleeping better. By most measures, they're sleeping worse.

The CDC has described insufficient sleep as a public health epidemic. Surveys consistently show that a significant portion of American adults regularly get less than the recommended seven hours. Rates of diagnosed insomnia have climbed. Anxiety about sleep — a condition sometimes called orthosomnia, where the obsession with achieving perfect sleep actually prevents sleep — has become common enough that therapists are treating it as a distinct presenting problem.

The harder people try to optimize their sleep, in other words, the more anxious they become about it, and the worse they sleep. It is a feedback loop that the sleep industry has, perhaps inadvertently, helped create. Every product that promises better sleep implicitly confirms that your current sleep is inadequate. Every morning report from your tracker that grades your night reinforces the idea that sleep is a performance to be evaluated rather than a process to be trusted.

What Actually Changed

It would be easy to blame the apps and the supplements and leave it there. But the sleep crisis has roots that go deeper than consumer technology.

Work culture changed dramatically. The smartphone effectively abolished the boundary between work hours and personal time, meaning that the mental state required for sleep — disengagement, decompression, a sense that the day is actually over — became harder to achieve. Chronic stress and financial anxiety, both of which have risen measurably over the past few decades, are among the most well-documented disruptors of sleep quality.

Screen time extended the day in ways that disrupted the body's natural light cues. Social media created a form of low-grade, constant stimulation that didn't exist before and that the human nervous system was never designed to handle at 11 PM.

The sleep industry didn't cause these problems. But it did respond to them by selling solutions that often address the symptom — the inability to fall asleep — rather than the underlying causes. A melatonin gummy doesn't fix the fact that you checked work email at 9:30 PM. A sleep tracker doesn't resolve the financial stress that's keeping you awake.

The Simplest Advice Is the Oldest Advice

Sleep researchers — actual clinical ones, not influencers — will tell you that the fundamentals of good sleep haven't changed much: consistency in your sleep and wake times, a cool and dark room, limiting alcohol and caffeine in the hours before bed, and reducing exposure to bright screens in the evening. These recommendations don't require a subscription or a wearable device. They're also, notably, more or less what your grandparents did by default, without knowing the science behind it.

The irony of the modern sleep moment is that the path back to sleeping well might involve doing considerably less, not more. Fewer products. Less tracking. Less performance anxiety about hitting the right percentages on an app that may not be measuring much of clinical value anyway.

Sometimes the most radical thing you can do is turn off the light and let your body remember what it already knows how to do.
