Sleep schedules differ among people, with some naturally preferring to go to bed early and others preferring to stay up late Trusted Source National Library of Medicine, Biotech Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information. See Full Reference . In everyday terms, people with a tendency to stay up late are often referred to as “night owls,” and those who sleep and wake early are called “early birds”.

A person’s sleep schedule preference is closely tied to their circadian rhythms, which are natural physical processes that follow similar patterns about every 24 hours Trusted Source National Institute of Neurological Disorders and Stroke (NINDS) NINDS aims to seek fundamental knowledge about the brain and nervous system and to use that knowledge to reduce the burden of neurological disease. See Full Reference . Since circadian rhythms are influenced by light exposure, meal timing, and exercise Trusted Source National Library of Medicine, Biotech Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information. See Full Reference , people can use these factors to naturally shift their sleep schedules.

Multiple studies suggest that a later sleep time Trusted Source National Library of Medicine, Biotech Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information. See Full Reference is associated with many health issues. But simply waking up early might not solve the problem. People who tend to stay up late can accumulate a sleep debt if they force themselves to wake up early without developing an earlier bedtime. However, shifting a night owl’s schedule, so they go to sleep and wake up earlier, may benefit them in several ways.

Compatible Sleep and Social Schedules

Work and school commonly begin early, which creates a mismatch with night owls’ sleep-wake schedules. This conflict between sleep and social obligations, like rigid work hours, can negatively affect both the health and work performance of people who naturally tend to stay up later.

People who prefer to stay up late may develop “social jet lag.” This involves waking up early for social reasons, like work or school, despite keeping a late bedtime. These late nights and early mornings result in an inadequate amount of sleep, which the person might try to make up for by sleeping more on their days off. While getting more sleep on weekends can be helpful, it is likely better for people to maintain a consistent sleep schedule every night of the week.

When a person’s sleep schedule does not align with their social requirements, they might perform poorly at school or work, experience anxiety, and have personal relationship complications. Shifting the sleep schedule earlier may help a person avoid some of the negative effects of inconsistent sleep and sleep that misaligns with social schedules.

If shifting a person’s sleep schedule earlier allows them to sleep more, it could have additional positive consequences. Sleep deficiency is associated with health problems Trusted Source National Heart, Lung, and Blood Institute (NHLBI) The NHLBI is the nation's leader in the prevention and treatment of heart, lung, blood and sleep disorders. See Full Reference such as heart disease, high blood pressure, diabetes, and depression, as well as a higher risk of accidents and injuries.

Improved Mental Health

Research shows that people who tend to sleep and wake later are more likely to experience anxiety and depression Trusted Source National Library of Medicine, Biotech Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information. See Full Reference than those who sleep and wake earlier.

However, a recent study suggests that people who prefer a late bedtime may be able to reduce their mental health risks by adjusting the time they sleep. In this study, those who shifted their sleep schedules earlier by about two hours reported lower levels of depression and stress compared to those who did not shift their sleep schedules. More research may determine if changing one’s sleep schedule could help treat such disorders.

Improved Performance

Early birds and night owls not only sleep on different schedules, they also experience peak performance at different times of day. For example, those who stay up late tend to perform worse Trusted Source National Library of Medicine, Biotech Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information. See Full Reference in the morning at both physical and mental tasks.

One study found that shifting a night owl’s sleep time can improve performance and change their peak hours, perhaps by decreasing their daytime sleepiness. In this study, people who shifted their sleep schedules earlier by about two hours exhibited faster reaction times and increased grip strength.

Time for Morning Exercise

Shifting to an earlier sleep-wake schedule can open up time for morning exercise. Exercising regularly is often recommended as a low-cost treatment option Trusted Source National Library of Medicine, Biotech Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information. See Full Reference for getting more and better-quality sleep. Studies show that, compared with evening exercise, morning exercise Trusted Source National Library of Medicine, Biotech Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information. See Full Reference improves sleep quality in people who have trouble sleeping. Exercising close to bedtime, however, can have a negative impact on sleep.

Time for Breakfast

Waking up earlier provides more time to prepare a healthy breakfast. Healthy, high-protein breakfast options Trusted Source National Library of Medicine, Biotech Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information. See Full Reference with low sugar content have been shown to improve energy levels throughout the day. People who eat breakfast feel more alert in the morning and tend to be in a better mood than those who skip this meal.

Tips for Waking Up Early

Sleeping and waking up early may feel difficult for night owls. But with some guidance, they can successfully make the transition.

Make Gradual Changes

Instead of abruptly beginning an entirely new sleep schedule, ease into an earlier wake time Trusted Source National Heart, Lung, and Blood Institute (NHLBI) The NHLBI is the nation's leader in the prevention and treatment of heart, lung, blood and sleep disorders. See Full Reference over a few days. Start by going to sleep and waking up about 15 minutes earlier than normal. Then continue adjusting your schedule by 15 minutes each night until you reach the wake-up time you desire.

Get Morning Light

Since light and darkness affect circadian rhythms, you can help shift when you naturally want to wake up by being strategic with light exposure. Bright light exposure in the early morning helps people wake up and go to sleep earlier. Try taking a morning walk or spending time in sunshine early in the day to help reinforce your new sleep schedule.

Avoid Evening Light

Just as morning light exposure can shift your sleep schedule earlier, exposure to bright light in the evening can shift it later. Try to limit or avoid light exposure in the evening to avoid making your body want to stay up later.

UpToDate delivers evidence-based clinical decision support that is clear, actionable, and rich with real-world insights. See Full Reference in the hours before bed, since they can interfere with the ability to fall asleep.

Exercise Early

If you have trouble waking up as early as you would like, consider exercising earlier in the day. Research demonstrates that early-morning exercise can help a person shift to an earlier sleep schedule. By contrast, exercising in the evening might contribute to shifting the sleep hours later.

Time Your Meals

Like morning exercise, eating an early breakfast is another factor that may help a person keep an earlier sleep-wake schedule. In one study, researchers had people eat breakfast as soon as they woke up in order to help them shift to sleeping and waking earlier.

More research is needed, but some studies suggest that meal timing affects circadian rhythms, including when a person feels alert or ready to sleep. In addition to eating breakfast upon waking, try to eat lunch and dinner at the same time each day and avoid eating meals late in the evening.

Limit Caffeine

Research shows that caffeine Trusted Source National Library of Medicine, Biotech Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information. See Full Reference can impair a person’s ability to sleep, even if they consumed it six hours before bedtime. As you work toward going to sleep and waking up earlier, try to avoid coffee, tea, and other sources of caffeine later in the day.

Reward Yourself

Habit formation can be facilitated by rewards Trusted Source National Library of Medicine, Biotech Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information. See Full Reference . As you first shift your schedule, give yourself an incentive to help make going to sleep and waking up earlier feel worthwhile. Treat yourself to something special or enjoyable each time you fall asleep and wake up early.

Practice Healthy Sleep Habits

Practicing healthy sleep habits Trusted Source National Library of Medicine, Biotech Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information. See Full Reference can help people obtain higher-quality sleep. Try incorporating these healthy sleep habits to help you fall asleep more easily as you go to sleep earlier:

  • Go to sleep and wake up at the same times every day
  • Keep the bedroom dark, cool, and quiet
  • Remove computers, phones, and TVs from the bedroom
  • Avoid large meals, alcohol, and caffeine near bedtime
