And So to Bed: The Ancient Art of Winding Down in a World That Never Sleeps
There is something quietly radical about going to bed. In a culture that celebrates hustle, rewards the sleepless, and treats exhaustion as a badge of honour, the decision to close the day with intention — to say, as Samuel Pepys wrote so simply in his diary, “and so to bed” — feels almost like an act of defiance.
Pepys used that phrase hundreds of times across his famous diary, which he kept from 1660 to 1669. Night after night, after recording the gossip of the court, the terror of the plague, the glow of the Great Fire seen from across the Thames, he would draw his day to its close with those four words. They were not a dismissal of the day. They were a ritual completion of it. A full stop written not in ink but in the drawing of curtains and the snuffing of a candle.
We have largely lost that art. And we are suffering for it.
What We Talk About When We Talk About Sleep
Sleep science has exploded in the last two decades. We now know more about what happens to the brain and body during sleep than at any point in human history, and almost none of it is reassuring if you are currently getting five hours a night and calling it fine.
During sleep, the brain runs a kind of maintenance cycle. The glymphatic system — a network of channels that expands during sleep — flushes out metabolic waste products, including the amyloid proteins associated with Alzheimer’s disease. The hippocampus replays the day’s learning and transfers memories into long-term storage. Hormones that regulate appetite, stress response, immune function, and cellular repair flood the body in carefully timed waves. Growth hormone, which does everything its name suggests and more, is released almost exclusively during deep sleep.
Deprive someone of sleep for long enough and you will impair their cognition, destabilise their mood, compromise their immune system, elevate their blood pressure, and disrupt their metabolism in ways that resemble accelerated ageing. The research on this is not subtle or contested. It is overwhelming.
And yet. We scroll. We watch one more episode. We lie awake rehearsing tomorrow’s anxieties. We treat the hours between midnight and three in the morning as a kind of tax-free zone where normal rules don’t apply, where we can steal time from sleep without consequence.
The consequences, it turns out, are considerable.
The Bedtime Routine: Why It Matters More Than You Think
There is a reason we create bedtime routines for children and then abandon them the moment we become adults. We assume that because we are grown, we have somehow graduated beyond the need for transition rituals. We haven’t.
The human nervous system does not switch from alert to restful at the flip of a switch. It needs a ramp. A gradual descent from the stimulation of the day into the quiet of the night. Children who skip their bedtime routine become overtired and wired, unable to settle. Adults who skip theirs do exactly the same thing, they just have more practice ignoring the signals.
A bedtime routine is not about performing wellness or ticking boxes on a self-improvement checklist. It is about giving your nervous system the cues it needs to begin the transition from wakefulness to sleep. These cues work because of a beautiful piece of biological machinery: the circadian rhythm.
Your circadian clock is approximately twenty-four hours long and is anchored by light, temperature, food, and social cues. As evening falls, your body begins producing melatonin, the hormone of darkness, which signals to every organ in the body that night has arrived. Your core body temperature begins to drop. Your heart rate slows. Your alertness decreases.
This process is both automatic and sensitive. Bright light — especially the blue-wavelength light emitted by phones and laptops — tells the brain it is still daytime and suppresses melatonin production. Stress hormones, activated by an argument, a stressful email, or even an emotionally intense TV drama, push cortisol up at exactly the time the body is trying to bring it down. Eating late keeps the digestive system active during a window it expects to be quiet.
The bedtime routine, in short, is not a luxury. It is the scaffolding that allows your biology to do what it is trying to do.
Building an Evening That Ends Well
So what does a genuinely good pre-sleep routine look like? Not the Instagram version with silk pyjamas and a tower of expensive supplements, but the real thing — the version that works for actual people with actual lives.
The answer varies from person to person, because we are not all the same chronotype, do not all have the same pressures, and do not all have the same sleep challenges. But there are several principles that hold widely, built from both the science and from centuries of accumulated human wisdom about how to end a day well.
Begin earlier than you think you need to. Most people try to start their wind-down about twenty minutes before they want to be asleep. That is not enough. The nervous system needs longer than that, especially if your day has been stimulating, emotionally heavy, or physically demanding. An hour is a more realistic minimum. Two hours is better if you can manage it.
Dim the light in your home. This is one of the highest-return, lowest-effort interventions available to anyone who struggles to fall asleep at a reasonable hour. Bright overhead lights in the evening are a relatively recent invention, and they confuse your circadian clock. Switching to lamps, candles, or simply lowering the brightness of your environment in the last two hours before bed makes a measurable difference to melatonin onset and sleep quality. It also, somewhat magically, makes the evening feel different. More intimate. More like an ending.
Allow your mind to complete the day. One of the primary reasons people lie awake is that the mind has unfinished business. Open loops. Conversations half-processed. Tomorrow’s to-do list spinning. The old practice of journalling before bed — which Pepys understood intuitively, even if he didn’t have the neuroscience to explain it — helps the brain archive the day rather than rehearse it. You don’t need to write at length. A few sentences noting what happened, what you noticed, what you are grateful for, and what is on your mind for tomorrow can be enough to close those loops and give the thinking brain permission to rest.
Lower the temperature. Your core body temperature needs to drop by about one to two degrees Fahrenheit to initiate sleep. A cool bedroom — most sleep researchers suggest somewhere between sixty and sixty-seven degrees Fahrenheit, or around sixteen to nineteen degrees Celsius — supports this. A warm bath or shower an hour before bed counterintuitively helps because it draws blood to the surface of the skin, allowing heat to dissipate rapidly afterwards, which accelerates the temperature drop the body is working toward.
Guard the last thirty minutes jealously. This is the time most worth protecting. Whatever helps you feel calm, unhurried, and at peace with the day belongs here. Reading a physical book is one of the most recommended activities, and not just because screens are absent. The rhythm of reading — the slow, self-paced absorption of language — is itself calming. But it could be gentle stretching, listening to music you love, sitting quietly with a cup of herbal tea, or having a quiet conversation with someone you live with. The content matters less than the quality of presence it brings.
The Trouble With Screens (And Why We Keep Using Them Anyway)
It would be dishonest to write about bedtime routines without confronting the central difficulty most people face, which is that their phone is in their bedroom and they know they should not look at it and they look at it anyway.
The phone is not simply a source of blue light. It is a portal to an environment specifically engineered for engagement. Every notification, every scroll, every piece of content optimised for maximum attention capture is working directly against the process of winding down. Social media feeds, in particular, are designed to provoke emotional responses — outrage, envy, curiosity, amusement — that activate the nervous system rather than settling it.
This is not a willpower problem. It is a design problem. You are not weak for finding it difficult to put your phone down at ten o’clock at night. You are a person with normal human psychology encountering a device built by teams of engineers whose sole objective was to make it as hard as possible to put down.
The most reliable solutions are structural rather than aspirational. Charging your phone outside the bedroom removes the temptation entirely and forces you to own an actual alarm clock, which is a small price to pay for reliable sleep. Setting a specific time after which you do not open social media apps — and using the screen time controls on your device to enforce it — works better than relying on in-the-moment willpower. Telling someone you live with what you are trying to do and asking them to hold you to it works better still.
None of this is new information. But knowing something and doing something about it are different skills, and the latter usually requires changing your environment more than changing your mind.
What the Past Understood That We Have Forgotten
Pre-industrial sleep was different from ours in ways that are still being studied and debated. Before artificial light, people generally went to bed not long after dark, slept for several hours, woke naturally in the middle of the night for an hour or two of quiet wakefulness — what historians call “the watch” — and then slept again until dawn.
During the watch, people would pray, think, have conversations, make love, or simply lie in the dark with their thoughts. It was not insomnia. It was a different architecture of the night, suited to a different relationship with darkness.
The historian Roger Ekirch, who spent two decades researching this, found hundreds of references to “first sleep” and “second sleep” in pre-industrial literature and documents. The expectation that sleep should be one unbroken eight-hour block is, historically speaking, a very recent idea. One that may have created a great deal of unnecessary anxiety in people who wake naturally in the middle of the night and assume something is wrong with them.
If you are someone who wakes between two and four in the morning and cannot easily return to sleep, you may not have a sleep disorder. You may have an older kind of sleep. The recommended response — rather than lying in bed growing increasingly frustrated — is to get up, do something quiet and not too stimulating for thirty to sixty minutes, and then return to bed. Fighting it makes it worse. Working with it, as people once did naturally, can make it bearable or even, in its own strange way, pleasant.
The Ritual of Ending
There is something to be said for treating the end of the day with the same care and attention we bring to its beginning. Most of us have some kind of morning ritual, even if it is just coffee and a few minutes to gather ourselves before the day begins. The evening deserves equal respect.
Pepys understood this. His diary entries were themselves the ritual: the act of reviewing the day, finding its shape, recording its texture, and then formally closing it. The phrase “and so to bed” was not just a sign-off. It was a ceremony of completion.
We might not keep a diary. But we can find our own version of that ceremony. It might be as simple as washing your face at the same time each night, making the same small cup of tea, turning off the same lights in the same order, saying the same quiet thing to yourself or to whoever shares your home. Rituals do not have to be elaborate to be meaningful. They have to be consistent and intentional. They have to carry the weight of your attention.
That is what Pepys was doing, night after night, in the flickering candlelight of seventeenth-century London. Paying attention to the end of the day. Treating it as something that deserved to be noticed. Saying, in effect: this day happened, I was in it, and now it is done.
The Sleep You Actually Need
Before we close, it is worth being plain about what adequate sleep actually looks like for most adults. The research is consistent: seven to nine hours for most people, with individual variation at the margins. Teenagers need more. Young children need considerably more. The elderly often sleep less, but that appears to reflect a reduced ability to generate sleep rather than a reduced need for it.
Quality matters as well as quantity. Alcohol, which many people use as a sleep aid, is in fact a significant disruptor of sleep architecture. It helps you fall asleep but fragments your sleep later in the night and suppresses REM sleep, which is the stage most involved in emotional processing and memory consolidation. The sleep you get after several drinks is lighter, more broken, and less restorative than the sleep you get sober, even if it arrives more quickly.
Consistency of sleep and wake times is, if anything, more important than the total number of hours. Your circadian clock works best when it can predict when sleep is coming. Sleeping in on weekends to compensate for a sleep debt accumulated during the week is only partially effective and comes at the cost of what chronobiologists call “social jet lag” — the misalignment between your biological clock and your social schedule that leaves you feeling perpetually slightly off.
And So to Bed
At the end of the day, the most profound thing about sleep is how ordinary it is. It is not a hack. It is not an optimisation strategy. It is the thing your body has been doing for your entire life, and the thing it will do well if you get out of its way.
The invitation, then, is simply this: take the end of your day seriously. Give it some ceremony. Dim the lights. Put the phone down. Let the day close.
Say, in whatever words mean it for you, and so to bed.
And then go.
