A Sleep Routine You Can Keep: Schedule, Wind-Down and Log

A habit-based approach to sleep built on CDC and NIH guidance: a steady schedule, a short wind-down, daytime adjustments and a simple log. Not medical advice.

A sleep routine is a habit like any other: a set of behaviors tied to cues, repeated until they run with little effort. The difference is that the stakes feel higher, and the advice online is often contradictory, product-driven or both.

This guide sticks to what US federal health agencies actually recommend, the CDC and the National Heart, Lung, and Blood Institute, and treats it as a habit-building problem: pick a schedule, build a short wind-down, adjust a few daytime habits and keep a simple log so you can see what is working.

This is general information, not medical advice. If you have ongoing sleep problems, a health care provider is the right person to talk to.

How much sleep the CDC recommends

The CDC's About Sleep page lists recommended daily sleep by age. For adults it recommends:

Ages 18 to 60: 7 or more hours.
Ages 61 to 64: 7 to 9 hours.
Ages 65 and older: 7 to 8 hours.

For teens aged 13 to 17 the recommendation is 8 to 10 hours. The CDC also stresses that quality matters, not just hours. It describes quality sleep as uninterrupted and refreshing, and lists trouble falling asleep, repeatedly waking up during the night and feeling sleepy or tired even after getting enough sleep as signs of poor sleep quality.

These numbers give you a target for your schedule. If you need to be up at 6:30 and you want at least 7 hours of sleep, you need to be asleep by 11:30, which usually means being in bed somewhat earlier.

Anchor on a consistent schedule

The first habit on both agencies' lists is the same. The CDC lists going to bed and getting up at the same time every day. NHLBI recommends the same, and adds that you should try to keep the same sleep schedule on weeknights and weekends, limiting the difference to no more than about an hour. It explains that staying up late and sleeping in late on weekends can disrupt your body clock's sleep-wake rhythm.

From a habit perspective, a fixed wake time is a useful anchor. Psychologists Benjamin Gardner, Phillippa Lally and Jane Wardle, writing in the British Journal of General Practice in 2012, suggest tying a new habit to a time and place you encounter every day of the week, and a wake time fits that description: it is easy to notice and everything else in the morning can follow from it. A fixed bedtime gives your evening routine a clear endpoint.

Build a short wind-down

A wind-down is a mini-routine that starts at the same point each evening and ends with you in bed. NHLBI suggests using the hour before bed for quiet time, avoiding intense exercise and bright artificial light, such as from a TV or computer screen, because the light may signal the brain that it is time to be awake. The CDC suggests turning off electronic devices at least 30 minutes before bedtime. NHLBI also mentions a hot bath or relaxation techniques before bed.

A hypothetical wind-down for someone with an 11:00 bedtime:

10:00: after I set my alarm, I plug my phone in outside the bedroom.
After I plug in my phone, I dim the lights and take a shower.
After I shower, I read a paper book in bed until I feel sleepy.

Keep it short and repeatable. The point is for the first step to become a cue that the night is ending.

Adjust daytime habits that affect the night

Several of the agencies' recommendations are about what happens long before bedtime:

Caffeine. The CDC suggests avoiding caffeine in the afternoon or evening. NHLBI notes that caffeine's effects can last up to 8 hours, so a cup of coffee in the late afternoon can make it hard to fall asleep at night, and lists caffeinated soda, tea and chocolate as sources alongside coffee.
Nicotine. NHLBI notes that nicotine is also a stimulant that can interfere with sleep.
Meals and alcohol. The CDC suggests avoiding large meals and alcohol before bedtime. NHLBI says to avoid heavy or large meals within a few hours of bedtime, adding that a light snack is okay.
Daylight and activity. NHLBI recommends spending time outside every day when possible and being physically active. The CDC lists exercising regularly and maintaining a healthy diet.
Naps. NHLBI says that if you have trouble falling asleep at night, limit naps or take them earlier in the afternoon, and that adults should nap for no more than 20 minutes.

You do not have to change all of these at once. Pick the one that seems most relevant to you and treat it as a habit project of its own.

Set up the bedroom

The CDC recommends keeping your bedroom quiet, relaxing and at a cool temperature. NHLBI recommends keeping it quiet, cool and dark, noting that a dim night light is fine if needed. Environment design helps here, too: if your phone charges on the nightstand, it is cueing you to check it. Moving the charger is a one-time change that removes a nightly decision.

Keep a simple sleep log

A log turns a vague sense of "I slept badly this week" into something you can act on. The CDC describes a sleep diary that a provider may ask you to keep, recording when you go to bed, wake up during the night, wake up in the morning, take naps, exercise, drink alcohol or caffeinated drinks and take medications. A personal version can be simpler:

Bedtime and wake time.
Did I follow my wind-down? Yes or no.
Caffeine after noon? Yes or no.
How rested I feel, from 1 to 5.

After two weeks, look for patterns. How much do your bed and wake times vary? Do the nights you skipped the wind-down look different? A useful personal metric is schedule consistency: how many days this week your wake time was within an hour of your target. If you ever need to see a provider, a log also gives them real information to work with.

Shift work and when to get help

NHLBI notes that some people, such as shift workers, have schedules that conflict with their internal body clocks. Its suggestions for shift workers include naps to increase available sleep time, bright lights at work, limiting shift changes, limiting caffeine to the first part of a shift and removing sound and light distractions from the bedroom during daytime sleep. If you still cannot sleep or adapt, it advises talking with your doctor about other options.

More broadly, the CDC notes that some people have health conditions, called sleep disorders, that prevent them from getting enough quality sleep no matter how hard they try, and lists insomnia, restless legs syndrome, narcolepsy and sleep apnea as common examples. It advises talking to your health care provider if you regularly have problems sleeping or notice signs of a sleep disorder. If poor sleep comes with feelings of crisis or hopelessness, call or text 988 in the US.

Key takeaways

The CDC recommends 7 or more hours of sleep for adults aged 18 to 60, with slightly different ranges for older adults.
A consistent bed and wake time, within about an hour on weekends, is the anchor for everything else.
A short, repeatable wind-down with screens off and lights low helps signal the end of the day.
Caffeine, large meals, alcohol, nicotine and long naps are daytime habits worth reviewing.
A simple log shows patterns; regular sleep problems are a reason to see a health care provider.
