There is a bidirectional relationship between sleep and exercise. Engaging in physical activity can improve sleep quality and alleviate sleep-related problems, while getting a good night's sleep can promote healthier physical activity levels during the day. For instance, studies have found that a 30-minute increase in sleep onset was associated with a one-minute decrease in exercise duration the next day. Additionally, exercise increases the production of melatonin, a hormone that regulates sleep, and can act as a natural sleep aid. It is important to note that the timing of exercise also plays a role in improving sleep quality. While some people can exercise close to bedtime without any negative effects, others may find it disruptive. Therefore, it is recommended to finish workouts at least one to three hours before bedtime to allow the body to wind down.

What You'll Learn
Exercise can help you fall asleep faster
Regular physical activity has been shown to improve sleep quality and alleviate sleep-related problems. Engaging in at least 30 minutes of moderate aerobic exercise can improve sleep quality, with an increase in slow-wave sleep, which refers to deep sleep where the brain and body rejuvenate. This can be particularly beneficial for children, older people, and individuals with insomnia or other sleep disorders.
Exercising increases the production of melatonin, a hormone that regulates sleep, and reduces cortisol levels, leading to lower stress levels and better sleep. It also increases the body's need for sleep, making it easier to fall asleep. Additionally, the release of mood and energy-boosting chemicals during exercise can make you less likely to feel sluggish during the day, improving your overall sleep quality.
The timing of exercise is also important. While some people can exercise close to bedtime without any negative effects, others may find it disruptive. It is recommended to finish intense workouts at least one to three hours before bedtime to allow the body to wind down and prepare for sleep.
To optimize your sleep quality, it is essential to create a consistent and enjoyable exercise routine that fits your preferences and daily schedule. This can include a variety of activities such as walking, dancing, cycling, swimming, or yoga, which can help improve both your physical and mental well-being.

It increases the amount of slow-wave sleep
Exercise is closely intertwined with sleep. Studies have shown that physical activity can act as a natural sleep aid, promoting relaxation and reducing hyperarousal associated with insomnia. It is also known to alleviate sleep-related problems and help people get an adequate amount of rest.
While researchers don't fully understand the mechanism that explains how sleep and exercise are related, they do know that moderate aerobic exercise increases the amount of slow-wave sleep. Slow-wave sleep refers to deep sleep, where the brain and body rejuvenate.
Detailed analysis of the sleep electro-encephalogram (EEG) showed significantly increased delta power in slow-wave sleep (SWS) together with increased SWS stability in early sleep phases, based on delta wave envelope analysis. This means that the processes generating slow waves are more efficient after exercise.
The stability of slow waves is evaluated using fast-Fourier transformation, which measures delta (δ) power (typically 0.5-4 Hz) of the EEG. The delta waves can be quantitatively analysed using envelope analysis, which provides a tool for assessing the effect of manipulations on sleep that may otherwise go undetected.
Although vigorous exercise does not lead to a subjective improvement in sleep quality, sleep function is improved based on objective EEG parameters.

Working out can help stabilise your mood
Exercise also releases mood-boosting endorphins, which can create a level of activity in the brain that keeps some people awake. Therefore, it is important to exercise at least 1-2 hours before bedtime, giving endorphin levels time to decrease and allowing the brain to wind down. Low-impact exercises such as yoga and gentle stretching can also help calm the mind and prepare the body for sleep by relieving stress and muscle tension.
Exercising in the morning can make you more prepared to wind down at night, leading to better sleep quality. Engaging in physical activity during the day can also help to reduce stress, as it lowers cortisol levels, which can lead to better sleep.
In addition, creating a consistent exercise pattern that fits into your daily routine can support better sleep quality. Setting realistic goals and choosing enjoyable activities can help you stick to a routine.

It can reduce symptoms of sleep disorders
Exercise can help reduce symptoms of sleep disorders in several ways. Firstly, it increases the production of melatonin, a hormone that regulates sleep. Additionally, moderate aerobic exercise increases the amount of slow-wave sleep, which refers to deep sleep where the brain and body rejuvenate. This can be particularly beneficial for individuals with insomnia, as it promotes relaxation and reduces hyperarousal, making it easier to fall and stay asleep.
Exercising also helps stabilize mood and decompress the mind, which is important for naturally transitioning to sleep. It can reduce stress levels by lowering cortisol, improving overall mood and energy during the day, and enhancing cognitive function. This can be especially beneficial for individuals with insomnia, as it addresses the hyperarousal associated with the condition.
The timing of exercise is crucial when considering its impact on sleep disorders. While some people can exercise close to bedtime without any negative effects, others may find it disruptive. Intensive exercise within three hours of bedtime can increase heart rate, body temperature, and adrenaline levels, interfering with sleep. Therefore, it is recommended to finish workouts at least one to three hours before bedtime to allow the body to wind down.
The type of exercise performed can also influence sleep quality. Low-impact exercises such as yoga, stretching, and meditative runs can calm the mind and prepare the body for sleep by relieving stress and muscle tension. These activities promote relaxation and enhance mental focus, making it easier to transition to sleep.
Overall, exercise can be a powerful tool in managing sleep disorders. By improving sleep quality, increasing slow-wave sleep, reducing stress, and promoting relaxation, exercise can help alleviate symptoms associated with insomnia and other sleep disorders. However, individuals should be mindful of the timing and type of exercise to optimize its benefits for better sleep.

Morning workouts can make you more prepared to wind down at night
According to the National Sleep Foundation, those who exercise regularly report better quality sleep than those who don't work out. A combination of eight hours of sleep and at least 30 minutes of activity every day can also improve your mood, mental focus, and overall health. Morning exercise can help you get your daily workout out of the way and make you feel good. Research has found that people who regularly exercise, even for short amounts of time, feel happier than those who do not.
Exercising in the morning can also help you stick to a consistent routine. Consistency is key when it comes to working out, and morning workouts allow you to set aside a dedicated block of time in your schedule to meet your exercise goals. Morning workouts can also provide you with more access to group workouts and workout classes, which can help keep you motivated and reduce stress.
Additionally, morning workouts can improve your sleep quality by increasing the amount of slow-wave sleep you get. Slow-wave sleep refers to deep sleep, where the brain and body have a chance to rejuvenate. Exercise can also help stabilize your mood and decompress the mind, which is important for naturally transitioning to sleep. It increases the production of melatonin, a hormone that regulates sleep, and reduces the hyperarousal associated with insomnia.
While the specific relationship between sleep and exercise is not fully understood, the available evidence suggests that morning workouts can indeed make you more prepared to wind down at night and improve your overall sleep quality.
