Short answer
- Build the routine backward from a wake time you can keep every day, including weekends. Allow enough time in bed for the sleep adults are advised to get: the CDC lists 7 or more hours for adults aged 18 to 60, 7 to 9 hours for ages 61 to 64, and 7 to 8 hours for ages 65 and older. In the last hour before bed, slow down, prepare, and settle: dim the lights, put work and screens away at least 30 minutes before bedtime, write tomorrow down on paper, and do something quiet and relaxing. Keep the bedroom quiet, cool, and dark. During the day, get natural light early, stay active but finish exercise a few hours before bed, avoid caffeine in the afternoon and evening, and avoid large meals, alcohol, and nicotine close to bedtime. Keep naps short and early. If you are still awake after about 20 minutes in bed, get up, do something relaxing in low light, and return when you feel sleepy.
Introduction
Falling asleep is a shift, not a switch. The last hour of the day can either carry the day into bed with you, in bright light, late messages, heavy food, and a mind rehearsing tomorrow, or it can give your body a clear, repeated signal that the day is ending. A sleep hygiene wind-down routine is that signal, practiced in the same order often enough that the steps themselves start to feel like the beginning of sleep.
Sleep hygiene means the habits and bedroom conditions that support good sleep. This guide builds a routine for adults from guidance by the Centers for Disease Control and Prevention (CDC), the National Heart, Lung, and Blood Institute (NHLBI), and the National Institutes of Health (NIH). It covers how much sleep adults are advised to get, why light and timing matter, a 60 minute wind-down in three phases, the daytime choices that help or hinder, and when a routine is not enough.
This article is general information only. It is not medical advice, and it does not diagnose or treat insomnia or any other sleep disorder, or any other condition. If sleep problems continue, or if you notice loud snoring, gasping, pauses in breathing, or strong sleepiness during the day, talk with a qualified health professional rather than relying on a routine alone.
How Much Sleep Adults Need, and What Quality Means
The CDC gives adult sleep needs by age: 7 or more hours a night for ages 18 to 60, 7 to 9 hours for ages 61 to 64, and 7 to 8 hours for ages 65 and older. The NHLBI presents the same underlying recommendations in a simpler table, listing 7 to 9 hours a day for adults aged 18 years or older. Read the two together as a floor and a usual range: protect at least 7 hours, expect many adults to do well in the 7 to 9 hour range, and note the narrower CDC ranges at older ages.
These figures are population guidance, not a personal prescription. The NIH notes that sleep needs vary by person and change across life. Judge your nights by daytime function as well as hours. The CDC describes quality sleep as uninterrupted and refreshing sleep, not only a number of hours. Its signs of poor quality are trouble falling asleep, repeatedly waking during the night, and feeling tired even after enough sleep. If those signs are regular, adding time in bed alone may not fix the problem.
The CDC also sets out why enough sleep matters in general terms: it can help you get sick less often, reduce stress and improve mood, improve heart health and metabolism, lower the risk of conditions such as type 2 diabetes, heart disease, high blood pressure, and stroke, and improve attention and memory. Those are population level links over time, not a promise that one good week will produce any one of them for you.
Why a Wind-Down Works: Clocks, Light, and Sleep Drive
Two systems explain why the evening matters, and the NIH describes both. The first is the circadian rhythm, a cycle of about 24 hours controlled by internal clocks and set in part by light, darkness, and sleep schedules. When it gets dark, the brain increases melatonin, a hormone that helps you feel sleepy. As light returns, the body releases cortisol, which helps prepare you to wake. Artificial light can disrupt this by giving a false cue for wakefulness.
The second system is sleep-wake homeostasis, in plain language a sleep drive. The NIH explains that this drive gets stronger for every hour you are awake, and that a compound called adenosine is linked to that growing need for sleep. Caffeine can interrupt the process because it blocks the actions of adenosine. That explains two rules at once: why a full day awake can make sleep come more easily, and why caffeine taken hours earlier can still matter at bedtime.
A wind-down works with both systems. A regular schedule and morning light support the clock, dim light and no screens late in the evening stop sending wakefulness cues, and an early caffeine cutoff protects the sleep drive. None of this forces sleep. It removes signals that argue with sleep and replaces them with cues pointing one way.
Start With a Fixed Wake Time
The CDC advises going to bed and getting up at the same time every day, including on the weekends, and the NHLBI gives the same advice. Wake time is the anchor because bedtime drifts with events and late work, while wake time is usually the time you can protect. When it holds steady, evening sleepiness tends to arrive at a more predictable time.
Work backward in three steps. Pick a wake time you can keep seven days a week. Subtract the sleep you aim for to find a lights out time. Subtract your wind-down length to find when the routine starts. For example, if you wake at 6:30 a.m. and aim for 7 hours and 30 minutes of sleep, lights out is 11:00 p.m., because 6:30 a.m. minus 7 hours and 30 minutes equals 11:00 p.m. the night before. A 60 minute routine for that schedule starts at 10:00 p.m.
If your current schedule is far from the target, shift it gradually, by about 15 to 30 minutes every few days. That pacing is a practical suggestion, not a medical rule. The CDC occupational guidance adds an ideal to aim toward: going to bed early enough that you do not need an alarm to wake up. Most people will still use one. Treat it as a backstop, and still get up at the set time after a poor night, because that consistency is part of how the clock steadies.
The 60 Minute Wind-Down in Three Phases
Divide the last hour into three phases: 30 minutes to slow down, 20 minutes to prepare, and 10 minutes to settle: 30 plus 20 plus 10 equals 60. The NHLBI advises using the hour before bed for quiet time, avoiding exercise and bright light in that hour. The CDC occupational guidance suggests starting to prepare about 1 hour and 30 minutes before bedtime if you can. If your evening allows the longer version, start the same phases earlier. Order matters more than perfection.
Phase one, 30 minutes: slow the day down
Dim the lights first. Move from overhead lights to lower lamps and let the rooms get visibly darker. The CDC advises avoiding artificial light especially within a few hours of bedtime, and its occupational guidance advises transitioning to dim lighting during the preparation period, including not using a bright light in the bathroom.
Put work away and close the day on paper. Stop checking work messages and write a short list for tomorrow: the top tasks, anything you fear forgetting, and any worry that keeps returning. The point is not to solve those items at night, but to store them outside your head so your mind does not rehearse them in bed. Keep the list on paper, in another room if you can, rather than on your phone.
Choose a quiet activity for the rest of this phase. The NHLBI suggests a hot bath and relaxation techniques, and the NIH lists reading or listening to music as part of a bedtime ritual. Gentle stretching, a paper book, calm music, or a warm shower can all fit. The CDC occupational guidance advises avoiding excitement such as an action film or upsetting news in this period.
Phase two, 20 minutes: prepare the bedroom and tomorrow
Make the room quiet, relaxing, and cool, in the CDC words, and quiet, cool, and dark, in the NHLBI words. For darkness, close curtains or blinds fully, cover small indicator lights where you safely can, and use an eye mask if streetlights enter the room. The CDC occupational guidance advises a very dark room, opaque window coverings if needed, and an eye mask when outside light is hard to avoid.
For temperature, that guidance gives about 65 to 68 degrees Fahrenheit for most people, with covers added to stay warm. Treat it as a starting point, and adjust bedding, sleepwear, or a fan to feel comfortably cool. For quiet, close the door, silence nonessential alerts, and use soft earplugs or a fan or white noise machine if traffic, pets, or a partner disturb you, as the CDC occupational guidance suggests. Turn the clock face away so you do not repeatedly look at the time.
Charge devices outside the bedroom, or at least across the room. That removes scrolling in bed and notification lights and sounds, and leaves a book as the easier choice. If your phone is your alarm, set it in this phase, turn on Do Not Disturb, and leave it alone. Use a few minutes here for tomorrow too: lay out clothes and pack a bag, so nothing essential surfaces after lights out.
Phase three, 10 minutes: settle with the same steps
Keep the final steps short and identical each night: wash your face, brush your teeth, change into sleep clothes, get into bed, read a few pages if reading is part of your ritual, and turn the lights out. The CDC occupational guidance names these routine steps as helping you relax. Repetition is the mechanism: the same sequence teaches your brain what comes next.
Slow breathing can fill the last minutes for some readers: breathe in slowly through your nose and out slowly through your mouth, letting the out breath run a little longer. This is a relaxation practice, not a treatment. If it makes you more alert, drop it and keep the rest of the ritual.
Keep the bed for sleep as far as your home allows. The CDC occupational guidance advises using the sleep space only for sleep and intimacy, and not watching television, reading, or working in the bedroom, so the brain associates it with relaxation and sleep. In a small home, adapt the rule: do evening activities in a chair where you can, and let the bed remain the final step.
Screens: A Practical Plan, Not a Ban
The CDC advises turning off electronic devices at least 30 minutes before bedtime. The NIH goes further, advising readers to try not to look at a computer, phone, or television an hour or so before bed, because the light makes the brain think it is time to be awake. Either cutoff is workable. Pick one, set an alarm for it, and protect it.
Use night settings as support, not as a substitute. The CDC suggests a blue light filter when artificial light cannot be avoided, and the NIH notes that night mode may help reduce the impact of devices. Neither presents a filter as permission to scroll until lights out. Content matters as well as light: an absorbing argument or a feed offering one more item can keep you awake whatever color the screen is.
Replace screens rather than only removing them. Have a paper book, calm music, or the bath or stretching from phase one ready before the cutoff. A cutoff that leaves a bored vacuum is the one people abandon.
Daytime Habits That Shape the Night
Get natural light early. The CDC advises getting enough natural light, especially earlier in the day, and suggests a morning or lunchtime walk. Its occupational guidance advises about 30 minutes outside in sunlight, says bright light in the first hours is particularly helpful, and notes that time outside on a cloudy day is still better than only dim indoor light. The NIH gives the same target: at least 30 minutes of natural sunlight each day.
Set a caffeine cutoff you can calculate. The CDC advises avoiding caffeine in the afternoon or evening. The NIH explains why it needs to be early: the stimulating effects of caffeine in coffee, colas, certain teas, and chocolate can take 8 hours or more to wear off fully. The CDC occupational guidance advises avoiding caffeine, chocolate, and nicotine for 5 or more hours before planned sleep, and longer if you are sensitive. If lights out is 11:00 p.m., 8 hours before is 3:00 p.m., because 11 minus 8 equals 3. Sensitive readers can move the cutoff to early afternoon or noon. Count tea, chocolate, and energy drinks as sources too.
Move during the day, and time it sensibly. The CDC lists regular exercise among the habits that improve sleep, and its occupational guidance notes that even a 10 minute walk will improve sleep, while advising readers to finish exercise at least 3 hours before planned sleep. The NIH advises exercising regularly but not within a few hours of bedtime. Vigorous effort belongs earlier. Gentle stretching or a slow evening walk is a different matter from a hard workout ending just before bed.
Keep naps short and early. The NIH advises not taking naps after 3:00 p.m. and keeping naps to under an hour. Long or late naps spend the sleep drive building all day, leaving you less sleepy at bedtime. If you nap, set an alarm and keep it earlier in the afternoon. Needing frequent naps just to function is different: the CDC lists frequent naps among the reasons to call a doctor when you already spend 7 to 9 hours in bed.
Time meals, alcohol, and nicotine. The NHLBI advises avoiding heavy or large meals within a couple of hours of bedtime and avoiding alcoholic drinks before bed. The CDC occupational guidance advises avoiding heavy or spicy meals 3 hours before bedtime and limiting liquids several hours before sleep. On alcohol, the NIH is direct: alcohol keeps you in the lighter stages of sleep, and you tend to wake in the middle of the night when the sedating effect has worn off. Feeling drowsy after a drink is not sleeping soundly. On nicotine, the NHLBI and NIH both list it among the stimulants to avoid close to bed. This guide offers no advice on quitting methods, which belong with a health professional.
A Sample Schedule You Can Copy and Adjust
Here is the system on one clock, for a reader who wakes at 6:30 a.m. and aims for lights out at 11:00 p.m. Adjust the times to your own wake time with the backward method above, and keep the sequence.
During the day, get outside for about 30 minutes in morning light, finish hard exercise by about 8:00 p.m. on this schedule, keep caffeine to before 3:00 p.m., and finish any nap well before 3:00 p.m.
At 9:30 p.m., begin the longer preparation window if you use it: finish eating, dim the main lights, and put work away. At 10:00 p.m., start the 60 minute wind-down: write the tomorrow list, take a warm shower or bath or stretch gently, and read something calm. At 10:30 p.m., prepare the room, charge the phone outside the bedroom or across the room, lay out clothes, and turn off screens, giving the CDC cutoff of 30 minutes before lights out. At 10:50 p.m., run the settling ritual. At 11:00 p.m., read a few pages if that is part of your ritual, then lights out.
Notice what the sample does not contain: no supplement and no special product. It is a set of times, a darker and cooler room, and the same order repeated.
If You Cannot Sleep, and Other Common Problems
If you are still awake in bed, do not lie there for hours. The NIH advises that if you are still awake after more than 20 minutes in bed, you should get up and do a relaxing activity until you feel sleepy. Keep the light low, read something calm, and return when you feel sleepy. Keep the rule gentle, and avoid counting minutes on a clock.
A racing mind responds best earlier in the evening. The paper list from phase one is the main tool. Some readers add a short worry period after dinner, writing worries and a next step for each, then closing the notebook. If racing thoughts are frequent and distressing, that pattern deserves professional support rather than more sleep tips.
Waking in the middle of the night is common. Keep the night dark and boring: no bright lights, no phone, no repeated clock checks, and the same get up rule if you are fully awake for a long stretch. Frequent waking has many possible causes, and this guide does not sort them out.
Sleeping long enough but still feeling tired points to quality rather than duration. A useful next step that both the CDC and the NIH support is a sleep diary. The CDC says it should include when you go to bed, wake during the night, and wake in the morning, plus naps, exercise, alcohol and caffeinated drinks, and medications. The NIH suggests keeping it for a couple of weeks. It does not diagnose anything. It gives you and a clinician a pattern to discuss instead of a vague memory of bad nights.
Different schedules in one home need negotiation: a dark, quiet room after an agreed time, headphones for late media, and separate blankets if warmth preferences differ. Shift work makes all of this harder. Keep sleep times as regular as your rotation allows, make a daytime bedroom as dark, cool, and quiet as the nighttime version, and protect a wind-down before daytime sleep too. If shift work is seriously affecting your health, mood, or safety, discuss it with a health professional.
How to Start Without Rebuilding Your Evenings
Start with the anchor and one phase. In the first week, hold the wake time steady and run only phase one. In the second week, add the bedroom preparation, screen cutoff, and phone charging spot. Add the settling ritual once the first phases feel ordinary. That staged start is a practical suggestion, not a tested program. A shorter routine kept on a bad night protects the sequence better than skipping it because the full version no longer fits.
When to Seek Professional Help
Sleep hygiene supports sleep. It is not a treatment for a sleep disorder, and continuing problems are a reason to seek care, not to try harder at a routine. The CDC advises talking to your healthcare provider if you regularly have problems sleeping, and notes that a provider can run tests, including sleep studies, to tell if you have a sleep disorder.
The CDC occupational guidance gives thresholds for calling a doctor when you already spend 7 to 9 hours in bed: consistently taking 30 minutes or more to fall asleep, consistently awakening several times or for long periods, frequent naps, or often feeling sleepy at inappropriate times. The NIH lists similar signs, plus a bed partner reporting loud snoring, gasping, choking sounds, or pauses in breathing, creeping feelings in the legs or arms relieved by moving them, legs or arms jerking often during sleep, vivid dreamlike experiences while falling asleep, sudden muscle weakness with strong emotion, or feeling unable to move on waking.
No reader should use a list here to decide that they do or do not have a condition. Bring the pattern, and a sleep diary if you have one, to a qualified health professional.
The Bottom Line
A sleep hygiene wind-down routine is a sequence, not a shopping list. Keep a fixed wake time and work backward to a bedtime that protects at least 7 hours. Spend the last hour slowing down, preparing a quiet, cool, and dark room, and settling with the same steps. Support the night during the day with morning light, regular activity, an early caffeine cutoff, short and early naps, and no large meals, alcohol, or nicotine close to bedtime. Start with one or two changes and seek professional help if problems persist.
Frequently Asked Questions
How long should a wind-down routine be?
About an hour is a workable target. The NHLBI advises using the hour before bed for quiet time, and the CDC occupational guidance suggests preparing about 1 hour and 30 minutes before bedtime if you can. What matters is the protected sequence: dim light, no work, a calm activity, a prepared room, and the same settling steps. On a late night, run a shortened version in the same order, and keep the screen cutoff of at least 30 minutes even then.
What is a good caffeine cutoff time for sleep?
Work it out from your bedtime. The NIH notes that caffeine effects can take 8 hours or more to wear off fully, and the CDC advises avoiding caffeine in the afternoon or evening. For an 11:00 p.m. bedtime, 8 hours earlier is 3:00 p.m. Sensitive readers may do better with a cutoff at early afternoon or noon. Count chocolate and caffeinated soft drinks as sources too.
How cool, dark, and quiet should the bedroom be?
Aim for quiet, cool, and dark, the words the CDC and NHLBI both use. The CDC occupational guidance gives about 65 to 68 degrees Fahrenheit for most people, advises a very dark room with opaque coverings or an eye mask if needed, and suggests earplugs or a fan or white noise machine for noise. If you regularly wake hot, squinting at light, or listening to the street, the room is not yet set up for sleep.
What should I do if I am lying awake and cannot sleep?
Get up rather than staying in bed awake. The NIH advises that if you are still awake after more than 20 minutes in bed, you should get up and do a relaxing activity until you feel sleepy. Keep the light low, avoid screens and bright rooms, and return when drowsiness returns. Avoid watching the clock, because repeated checks raise frustration. If this happens on most nights for several weeks, talk with a health professional.
Does a nightcap help you sleep?
No. The CDC and NHLBI both advise avoiding alcohol before bed, and the NIH explains why: alcohol keeps you in the lighter stages of sleep, and you tend to wake in the middle of the night when the sedating effect has worn off. Drowsiness after a drink is the start of a more broken night, not a sign of better sleep.
Do naps always harm nighttime sleep?
Not always. The NIH advises avoiding naps after 3:00 p.m. and keeping naps to under an hour, because late or long naps spend the sleep drive that builds across the day. A short, early afternoon nap is a different choice from a long evening nap. If you regularly need frequent naps despite enough time in bed, the CDC counts that among the reasons to call a doctor.
