Sleep hygiene means the everyday habits and surroundings that support good sleep. It includes when you sleep, how you wind down, what your bedroom is like, and how caffeine, alcohol, meals and activity fit into your day.
It is a practical starting point, not a measure of willpower. Work hours, caregiving, discomfort and health conditions can all affect sleep. The aim is to make rest easier within your circumstances, not to follow a perfect bedtime routine.
Why sleep hygiene matters
Getting enough good-quality sleep supports attention, memory, mood and physical health. Both the amount and quality of sleep matter. Spending enough hours in bed is useful, but regularly struggling to fall asleep, waking repeatedly or feeling very sleepy during the day can signal that your sleep needs attention.
The CDC’s overview of healthy sleep explains how sleep needs vary with age and describes habits that can help. For adults aged 18 to 60, its general recommendation is seven or more hours per night. Individual needs and circumstances still matter.
The main parts of good sleep hygiene
A steady sleep schedule
Choose a wake-up time you can maintain on most days, and allow enough time for sleep before it. A fairly consistent schedule helps support your body’s sleep-wake rhythm. Try to keep differences between workdays and days off modest rather than repeatedly shifting your routine by several hours.
A room that supports rest
A quiet, dark and comfortably cool room can make it easier to settle. Adjust bedding to your comfort, reduce light where practical and deal with the most disruptive noise first. You do not need a particular gadget or an exact temperature to start.
A quieter end to the day
Use the last part of the evening for activities that help you slow down. You might read, shower, listen to quiet music or prepare a short list for tomorrow. Reduce bright light and stimulating screen use when possible, especially if they keep pushing bedtime later.

Daytime habits that fit your needs
Spend time outdoors when you can and build regular physical activity into your day. If intense exercise close to bedtime makes it harder to settle, move that session earlier and choose something gentler in the evening.
How naps fit in
A nap can give a short-term boost in alertness, but long or late naps may make nighttime sleep harder for some people. The NHLBI’s general guidance recommends limiting adult naps to no more than 20 minutes. If you have trouble sleeping at night, try limiting naps or taking them earlier.
Shift work and other unusual schedules may call for a different plan. If you are regularly so sleepy that you cannot function safely, do not rely on naps alone to address the problem.
Review caffeine, alcohol and evening meals
Caffeine’s effects can last up to eight hours. An afternoon or evening coffee, strong tea or energy drink may be worth reconsidering if you have trouble falling asleep. Choose a cutoff that gives you enough time to wind down, and adjust it to your sensitivity.
Alcohol can make you feel sleepy at first while disturbing sleep later in the night. It is better to build a comfortable routine than use alcohol as a sleep aid.
Avoid going to bed immediately after a large, heavy meal if it leaves you uncomfortable. A light snack is fine when you are hungry. Our guide to food and sleep explains practical choices and the limits of sleep-food research.
Sleep hygiene is not the same as insomnia treatment
Good habits can support sleep, but a persistent sleep problem is not proof that you are doing something wrong. Talk with a healthcare professional if difficulties continue, interfere with your day or occur with concerning symptoms.
For long-term insomnia, cognitive behavioral therapy for insomnia, or CBT-I, is usually the first treatment recommended. It combines several approaches tailored to sleep difficulties; it is more than a list of hygiene tips. Other sleep disorders need their own assessment and care.
A simple way to get started
- Identify one obstacle. Is it a late coffee, a bright room, an inconsistent schedule or work continuing right up to bedtime?
- Choose a realistic adjustment. Move that coffee earlier, reduce the light, set a steadier wake time or give work a stopping point.
- Notice the pattern over several days. Keep brief notes about your nights and daytime energy instead of judging the whole plan after one night.
