Why Is Sleep Important?

As couples, historically it appears we never grasped how practical it was to sleep in separate beds.

Framing separate sleeping arrangements as a form of marital dissolution is actively harmful.

Did you know that back in the '50s, twin beds were marketed as "doctor-recommended"?

In Downton Abbey, there is a room in the mansion simply referred to as “Lady Cora's bedroom.” Lord Grantham? He has his own as well. But no one weeps or thinks this smacks of a lack of intimacy between the two. If you watched the series or caught the movie spinoffs, the couple is, by all accounts, devoted to one another. The arrangement? Perhaps it’s one that might be called... civilized.

Thing is, it appears that we never quite grasped how civilized it was in terms of what we spend a huge chunk of our lives doing—sleeping.

For most of human history, bedroom and bed-sharing had everything to do with economics and square footage and very little to do with love. It was about the wealth of space. Rich folks had it. Most others did not. So they used it. Often the two rooms were connected by a dressing room or a shared bath. Of course, the wealthiest couples each had their own set of servants as well.

The working class was crammed into small cottages and urban tenements. Like children of the Great Depression, they shared beds out of necessity. Sometimes they even shared their beds with their children. And the most destitute may have even shared them with strangers. It was about having a place to sleep. Separate sleeping was, perhaps, a privilege. And yet somewhere along the way, we took the whole thing and turned it on its head, deciding that sharing a bed was the truest measure of a healthy marriage.

While I could go into the history of all this, many of us never knew that the twin bed was introduced as a health reform. Doctors at that time genuinely believed that a weaker sleeper would drain the vitality of a stronger one, and that separate beds were the hygienic, modern solution. By the early 20th century, furniture catalogs were even marketing his-and-her beds as "doctor recommended.”

Twin beds for married couples were represented throughout the 1950s and even early ‘60s in TV shows like I Love Lucy and The Dick Van Dyke Show primarily because of Hollywood decency standards. That is, until the emphasis on "togetherness" flipped the script entirely. Sample an image of the 1950s depicted in the movie Pleasantville—where people shrieked as they walked by a furniture store displaying a scandalous double bed.

By the early 1970s, twin beds became old-fashioned and prudish—even vaguely suspicious, as if they were a referendum on the relationship itself. Truth be told, we are still living inside that cultural void. And it’s costing us sleep—especially those of us past age 55. Science tells us that sleep changes with age, and not in our favor. After 60, it becomes lighter, more fragmented, and less restorative. The deep sleep we experienced in our younger years was the kind that repaired the body and even consolidated memory. But that quality of slumber decreases measurably with each passing decade. Nearly half of adults over 60 report insomnia symptoms at some point, which is perhaps why melatonin and CBD sleep gummies are flying off shelves—perhaps even why Ambien addiction is an issue. In fact, just one night of poor sleep in adults older than 61 can accelerate the aging process at a cellular level. Nope. We are not imagining it. The body genuinely makes sleep harder to come by as we get older.

Now add a partner to the equation—that person you pledged undying love for who snores, runs hot, keeps different hours, has restless legs, or needs to fall asleep watching TV. These recurring nightly habits do not a peaceful night’s sleep make. It’s not about character flaws. These are simply the normal afflictions of two aging bodies trying to share the same mattress or even the same room. Yet even empty nesters with vacant bedrooms in their homes often silently endure years of less-than-optimum sleep rather than suggest an alternative. Why? Because the suggestion itself can feel like an accusation.

Rand Corporation sleep researcher Wendy Troxel spent her career studying couples and sleep and puts it bluntly: Chronic sleep deprivation erodes mood, empathy, and patience—the very things a relationship runs on. What’s ironic about it is that couples resist, staying in the same bed to preserve the appearance of intimacy as if there might become a line in one another’s eulogies someday. What they won’t talk about is that they may have been chronically exhausted and so irritable that intimacy had gone by the wayside long before. At one point it wasn’t so much about “waking up together” as it was “getting up on the wrong side of the bed” because of lack of sleep.

Whoever termed “sleep divorce" should be sentenced to a decade of someone else's snoring, flopping, opposed bedtime hours, and continuous recordings of toilet-flushing. Framing separate sleeping arrangements as a form of marital dissolution is not only wrong—it's actively harmful, shaming couples out of a practical solution before they've even considered it.

What the research does tell us is that relationship quality and sleep quality are deeply intertwined in both directions. It is, however, primarily because of the way each person in the couple frames it. Those who feel emotionally connected sleep better. Those who sleep better are kinder to each other during the day. The arrangement that supports both—the bed you share, or the room you don't—is the right one. There is no universal answer, and there is no reason to feel guilt or shame for opting for a better night’s sleep if that means a separate bed or bedroom.

Face it: physical intimacy and sleep are entirely separate activities. Can you recall, however, when hearing “they slept together” only meant sex? How about “made passionate love”? In the 40s, it meant “necking”—a term today’s millennials laugh out loud at. By the ‘60s, it was tearing each other’s clothes off.

All those lovely pheromones released by the closeness of a body next to yours and whispered conversations in the dark? None of them require spending eight hours in the same bed. Couples who sleep apart while maintaining nightly rituals delight in reading, talking, a proper goodnight, and often report that the separation actually sharpens their appreciation for those special intimate moments rather than diminishes them. Warmth without the sleep deprivation. Just think of it.

Perhaps the affluent couples of Downton and Gilded Age America understood something we've since romanticized away: that rest is not a rejection of love. The person who sleeps well is a better partner, a more patient companion, a more present human being.

The “marital bed” was never the point. The marriage and quality of life was.
