A good night’s sleep does not always begin when your head touches the pillow. It is often influenced by the choices you make throughout the day, the routine you follow before bed and the environment in which you sleep.
These habits and conditions are collectively known as sleep hygiene.
Good sleep hygiene can make it easier to fall asleep, remain asleep and wake feeling refreshed. It can also help you maintain a more consistent sleep schedule instead of alternating between restless nights, late mornings and attempts to catch up on missed sleep.
Sleep problems are common. According to a 2024 report from the Centers for Disease Control and Prevention’s National Center for Health Statistics, 30.5% of U.S. adults averaged less than seven hours of sleep per day. Only 54.8% reported waking well-rested most days or every day. The report also found that 15.4% regularly had trouble falling asleep and 18.1% regularly had trouble staying asleep.
What Is Sleep Hygiene?
Sleep hygiene refers to the daily habits, routines and environmental conditions that support healthy sleep.
It includes more than simply going to bed early. Your sleep hygiene can be affected by:
- When you go to bed and wake up
- What you do during the hour before bed
- Your exposure to light and electronic screens
- When you consume caffeine, alcohol and large meals
- Your level of physical activity
- The temperature, noise and light inside your bedroom
- The comfort and condition of your mattress, pillows and bedding
The CDC and the National Heart, Lung, and Blood Institute recommend habits such as maintaining a consistent sleep schedule, creating a quiet and relaxing bedroom, limiting evening light exposure and avoiding caffeine or large meals close to bedtime.
Sleep hygiene is not a single treatment or product. It is the combination of behaviors that encourages your mind and body to recognize when it is time to become alert and when it is time to rest.
Why Good Sleep Hygiene Matters
Sleep is an active biological process rather than a period when the body simply shuts down. During sleep, the brain processes information and supports learning and memory. Sleep also contributes to physical recovery, immune function, emotional regulation and the ability to concentrate during the day.
Good sleep hygiene matters because it helps create the conditions your body needs to complete these processes consistently.
It supports sufficient, good-quality sleep
The American Academy of Sleep Medicine and Sleep Research Society recommend that healthy adults sleep at least seven hours per night on a regular basis. Individual needs differ, and some adults function best with more than seven hours.
Time in bed is not always the same as time asleep. A person may spend eight hours in bed but still receive poor-quality sleep if they struggle to fall asleep, awaken repeatedly or remain uncomfortable through the night.
Healthy sleep hygiene supports both the amount and continuity of sleep.
It can improve daytime performance
Poor or insufficient sleep can make it more difficult to focus, think clearly, learn new information and form long-term memories. It can also affect reaction time, judgment and the ability to complete ordinary daily activities safely.
A consistent sleep routine does not guarantee that every day will feel effortless, but it can reduce some of the preventable habits that contribute to daytime tiredness.
It supports long-term health
Regularly sleeping fewer than seven hours has been associated with an increased risk of health problems including obesity, diabetes, high blood pressure, heart disease, stroke, anxiety and depression. Insufficient sleep can also contribute to motor vehicle crashes and workplace errors.
These associations do not mean that one restless night will cause a chronic illness. They do show why healthy sleep deserves the same ongoing attention as nutrition and physical activity.
It reinforces the body’s internal clock
Your sleep-wake cycle is influenced by the body’s internal timing system, commonly called its circadian rhythm. Going to sleep and waking at dramatically different times from day to day can make it harder for the body to anticipate when it should feel sleepy or alert.
A National Sleep Foundation expert panel concluded that consistent bedtimes and wake times are associated with better alertness and improved mental, cardiovascular and metabolic health.
A large observational study involving more than 60,000 UK Biobank participants also found that greater sleep regularity was associated with a lower risk of premature death. Because this was an observational study, it cannot prove that an irregular schedule directly caused the difference in risk, but it supports regularity as an important part of overall sleep health.
How to Practice Good Sleep Hygiene
Healthy sleep habits do not have to involve an elaborate routine. Simple behaviors practiced consistently are usually more useful than a complicated plan that is difficult to maintain.
1. Keep a consistent sleep schedule
Try to go to bed and wake up at approximately the same time every day, including weekends.
The NHLBI recommends limiting the difference between weekday and weekend sleep schedules to about one hour when possible. Sleeping very late on days off may temporarily feel helpful, but large schedule changes can disrupt the body’s regular sleep-wake rhythm.
Begin by choosing a realistic wake-up time. Then work backward to establish a bedtime that gives you enough opportunity to obtain at least seven hours of sleep.
2. Create a relaxing transition into sleep
The hour before bed should help your body move from daytime activity to nighttime rest.
A calming routine might include:
- Taking a warm shower or bath
- Reading a printed book
- Listening to quiet music
- Stretching gently
- Preparing clothing or lunches for the next day
- Practicing slow breathing
- Writing down tomorrow’s tasks so you do not have to mentally rehearse them in bed
Following a similar sequence each evening can become a cue that the active portion of the day is ending. Government sleep guidance recommends using the hour before bedtime for quiet activities while reducing bright light and vigorous activity.
3. Make the bedroom comfortable, dark and quiet
Your bedroom should communicate that it is a place for rest.
The CDC and NHLBI recommend keeping the sleep environment quiet, relaxing, dark and comfortably cool. Blackout curtains, an eye mask, earplugs or a steady fan may help when outside light or noise cannot be controlled.
Physical comfort matters as well. A mattress that sags, creates uncomfortable pressure or no longer supports your preferred sleep position may cause you to shift frequently during the night. Your pillow should also support your head and neck without pushing them into an uncomfortable angle.
The goal is not to create a picture-perfect showroom. It is to remove avoidable sources of light, noise, heat and physical discomfort.
4. Reduce screen use before bed
Phones, tablets, televisions and computers can interfere with a bedtime routine in several ways. Their light may increase evening alertness, while messages, videos, games and social media can keep the brain mentally engaged long after you intended to stop.
The CDC recommends turning off electronic devices at least 30 minutes before bedtime.
Research also supports paying attention to how screens are used. A systematic review of adolescents and young adults found that digital media use, particularly at bedtime or during the night, was associated with shorter sleep duration and poorer sleep quality.
Another 2024 study found that screen use after getting into bed was associated with impaired sleep, especially when the activity was interactive or involved multitasking.
A practical first step is to charge your phone away from the bed and use a separate alarm clock. This removes the temptation to check one more notification after turning out the light.
5. Be mindful of caffeine
Caffeine can remain active in the body for hours. Coffee, tea, cola, energy drinks, chocolate and some medications may therefore affect sleep even when consumed well before bedtime.
The CDC recommends avoiding caffeine during the afternoon or evening.
Individual sensitivity varies. Someone who has difficulty sleeping may need to move their final caffeinated drink earlier in the day and observe whether their sleep improves.
6. Avoid heavy meals and alcohol near bedtime
Going to bed immediately after a large or heavy meal can cause discomfort that makes sleep more difficult. Alcohol may initially produce sleepiness, but it can interfere with sleep later in the night.
CDC and NHLBI guidance recommends avoiding large meals and alcoholic drinks close to bedtime.
When you are genuinely hungry before bed, a light snack may be more comfortable than either a large meal or trying to sleep while hungry.
7. Get daylight and physical activity during the day
Daytime habits help prepare the body for nighttime rest.
Regular physical activity is associated with better overall health and can support healthy sleep. Natural morning and daytime light also helps reinforce the distinction between the active part of the day and the sleeping period.
The NHLBI recommends spending time outside when possible and being physically active during the day. It also recommends avoiding intense exercise and bright light during the quiet period immediately before bed.
8. Use naps carefully
A brief nap can be helpful when you are tired, but long or late-afternoon naps may make it more difficult to become sleepy at your usual bedtime.
The NHLBI advises adults who have trouble sleeping at night to limit naps or take them earlier in the afternoon. Its general guidance suggests keeping adult naps to no more than about 20 minutes.
People who work overnight or irregular shifts may require a different strategy. Their sleep schedule should be designed around their working hours rather than conventional nighttime sleep.
9. Do not turn sleep into a nightly performance test
Trying to force yourself to sleep can make bedtime feel stressful. Avoid repeatedly checking the clock or calculating how many hours remain before morning.
Instead, focus on the habits you can control: your schedule, evening routine, bedroom environment and daytime choices. Sleep hygiene works best as a consistent pattern rather than a test you must pass every night.
An occasional poor night does not mean that your routine has failed. Travel, illness, stress, caregiving and unexpected events can disrupt anyone’s sleep.
10. Change one or two habits at a time
Attempting to rebuild your entire daily schedule overnight can be difficult to sustain.
Start with the habit that is creating the most obvious disruption. That might mean:
- Establishing a regular wake-up time
- Moving the phone away from the bed
- Stopping caffeine earlier
- Darkening the bedroom
- Replacing an uncomfortable pillow
- Beginning a 30-minute wind-down routine
Practice the change consistently before adding another. A simple sleep diary can help you identify patterns involving your bedtime, wake time, caffeine, exercise, screen use and how rested you feel in the morning.
Is Sleep Hygiene Enough to Treat Insomnia?
Good sleep hygiene provides a healthy foundation, but it is not a cure for every sleep problem.
Chronic insomnia, sleep apnea, restless legs syndrome, medication side effects, pain and other medical conditions may continue to disrupt sleep even when a person follows an excellent routine.
For adults with chronic insomnia, the American College of Physicians recommends cognitive behavioral therapy for insomnia, usually called CBT-I, as the initial treatment. CBT-I includes several behavioral and cognitive techniques, with sleep-hygiene education forming only one part of the broader program.
Speak with a healthcare professional when you regularly struggle to sleep, continue feeling exhausted despite allowing enough time for sleep or experience symptoms such as:
- Loud, frequent snoring
- Gasping or choking during sleep
- Breathing that repeatedly stops and restarts
- Severe daytime sleepiness
- Persistent difficulty falling or staying asleep
- Sleepiness while driving or performing safety-sensitive work
Snoring, gasping, interrupted breathing and excessive daytime sleepiness can be symptoms of sleep apnea and should not be addressed through sleep-hygiene changes alone.
Better Sleep Begins Before Bedtime
Sleep hygiene is the collection of everyday habits that prepares your mind, body and bedroom for rest. It includes maintaining a consistent schedule, creating a calming evening routine, limiting screens and stimulants, staying active during the day and making the bedroom comfortable.
You do not need to perfect every habit at once. Begin with one manageable change and repeat it consistently. Over time, those choices can create a stronger and more predictable foundation for healthy sleep.
A supportive sleep environment is only one part of sleep hygiene, but it is an important one. When discomfort, sagging or inadequate support repeatedly causes you to shift positions or wake during the night, it may be time to evaluate whether your mattress and pillow still suit the way you sleep.
