Exercise and sleep are closely intertwined, and there is growing evidence that physical activity can improve sleep quality and duration. Regular physical activity can lead to reduced sleep latency, improved sleep quality, and better overall sleep health. The effects of aerobic exercise on sleep are similar to those of sleeping pills, and even a 10-minute workout during the day can lead to a deeper, more satisfying night of sleep. However, the timing of exercise is also important, as exercising too late in the day can interfere with sleep for some people.

What You'll Learn
Morning exercise may be better for sleep than evening exercise
Exercise is closely associated with better sleep. Regular physical activity can lead to improved sleep quality, reduced sleep latency, and better overall sleep quality. However, the time of day one exercises may also play a role in the quality of sleep.
Some studies suggest that morning exercise may be better for sleep than evening exercise. People who work out in the morning, especially outdoors, are said to sleep more hours each night, have deeper sleep cycles, and spend more time in restorative stages of sleep than those who exercise at other times of the day. Morning exercise contributes to the natural decline in blood pressure at night, allowing the body to heal, restore, and recover during deep sleep. Additionally, morning workouts allow the body temperature to drop and energy-raising endorphins to leave the system before bedtime, promoting sleepiness.
Exercising in the morning can also help regulate circadian rhythms, which are essential for maintaining a healthy sleep-wake cycle. Disruptions to this cycle can lead to sleep disorders like insomnia. Adjusting workout schedules to fit one's circadian rhythm may help alleviate sleep disturbances. For individuals with insomnia, cardio workouts or aerobic exercises performed in the morning can be beneficial, improving sleep quality and reducing symptoms.
While morning exercise may have benefits for sleep, it is important to note that individual preferences and responses vary. Some people may find that exercising close to bedtime does not interfere with their sleep. Listening to one's body and understanding how exercise timing affects sleep quality can help determine the optimal time of day to work out.

Exercise can reduce stress and lower cortisol levels
Exercise can help reduce stress and lower cortisol levels, which can improve sleep quality. Cortisol is known as the "stress hormone", and high levels of it can impair sleep quality and duration. According to a 2021 research review, physical activity, such as brisk walking or high-intensity interval training (HIIT), can effectively reduce cortisol levels. The intensity of the workout seems to be a factor, with higher-intensity exercises potentially having a greater impact on cortisol levels.
Regular physical activity, especially of moderate intensity, has been linked to improved sleep quality and reduced sleep disorders. This is due to the decrease in stress hormones and the promotion of relaxation. Additionally, moderate-to-vigorous exercise can aid in weight management, reducing the risk of obesity-related sleep issues such as obstructive sleep apnea (OSA).
The timing of exercise can also play a role in its effectiveness in reducing stress and improving sleep. Some people may find that exercising too late in the day interferes with their sleep due to increased endorphin levels and core body temperature, which can make it difficult to wind down. However, for those with insomnia, exercising in the evening may not be an issue, as studies suggest that evening exercise does not disrupt sleep quality. Nonetheless, it is generally recommended to finish workouts at least one to two hours before bedtime to allow the body to relax and prepare for sleep.
Overall, exercise, particularly of moderate intensity, has been shown to reduce stress and lower cortisol levels, which can promote better sleep. The relationship between exercise and sleep is complex, and individual factors, such as timing and exercise type, can influence the effectiveness of exercise in improving sleep quality.

Exercise can help treat insomnia
The effects of aerobic exercise on sleep appear to be similar to those of sleeping pills. However, more research is needed to compare physical exercise to medical treatments for insomnia. It is important to note that unlike healthy people, exercising six or more times a week could lead to poor sleep quality among insomnia patients. Three months or less of physical exercise was more effective in improving sleep quality than longer periods.
Exercising in the morning can enhance sleep potential and boost cardiovascular conditioning. Morning workouts contribute to achieving a nighttime decline in blood pressure, allowing the body to heal, restore, and recover during deep sleep. Additionally, exercising outdoors in the morning provides exposure to bright sunlight, which helps regulate circadian rhythms.
The type of exercise also plays a role in improving sleep quality. Cardio workouts or aerobic exercises, such as swimming, biking, jogging, or walking, are recommended for treating insomnia. Aerobic exercises increase the amount of slow-wave sleep, which refers to deep sleep where the brain and body rejuvenate. Yoga and other forms of breathing or stretching exercises are excellent choices for evening workouts as they encourage relaxation.
Overall, exercise is a promising approach to managing insomnia and improving sleep quality. However, it is essential to tailor the exercise regimen to the specific needs of individuals with insomnia.

Aerobic exercise increases slow-wave sleep
Exercise is known to promote better sleep. Researchers have found that moderate aerobic exercise increases the amount of slow-wave sleep one gets. Slow-wave sleep refers to deep sleep, during which the brain and body rejuvenate. This is the quietest and most restful phase of sleep, which helps with muscle and bone repair and strengthens the immune system.
Aerobic exercise causes the body to release endorphins, which create a level of activity in the brain that may keep some people awake. Therefore, it is recommended that individuals who find that exercising close to bedtime keeps them up at night should exercise at least 1-2 hours before going to bed, giving their brain time to wind down.
The effects of aerobic exercise on sleep are similar to those of sleeping pills. However, more research is needed to compare physical exercise to medical treatments for insomnia. A 2021 study found that exercising vigorously for 1 hour in the evenings might enhance the slow-wave sleep phase, improving overall sleep quality. However, another study found that vigorous exercise does not lead to a subjective improvement in sleep quality.
Overall, aerobic exercise is beneficial for increasing slow-wave sleep, and individuals should experiment with different timings to find what works best for them.

Exercise can decrease sleep complaints
Regular physical activity can lead to improved sleep quality, reduced sleep latency, and better overall sleep quality. Moderate-intensity physical activities are the most effective, while high-intensity physical activities, especially in the evening or close to bedtime, may lead to difficulty sleeping. For instance, aerobic exercises increase the amount of slow-wave sleep, or deep sleep, that one gets. Slow-wave sleep is when the brain and body rejuvenate.
Exercising in the morning is the perfect time to enhance sleep potential and boost cardiovascular conditioning. People who work out in the morning sleep more hours each night, have deeper sleep cycles, and spend more time in restorative stages of sleep than those who exercise at other times of the day. Morning workouts also contribute to achieving a nighttime decline in blood pressure, which is crucial for the body to benefit from sleep.
Exercising outdoors in the morning provides the added benefit of exposure to bright sunlight, which helps regulate circadian rhythms. Circadian rhythms are the body's internal clock, telling the body when it is time to fall asleep and wake up. Adjusting one's workout schedule to fit their circadian rhythm may help support their body clock and alleviate sleep disturbances.
