Exercise is known to promote relaxation, reduce anxiety, and stabilize your mood, all of which can help you sleep better. However, the conventional wisdom has been that exercising too close to bedtime can interfere with sleep. Recent studies have challenged this notion, suggesting that moderate-intensity exercise can help you fall asleep faster and improve sleep quality, even when performed in the evening. Nevertheless, vigorous exercise within an hour of bedtime can raise your heart rate and body temperature, making it harder to fall asleep. Therefore, the key to exercising before sleep is to be mindful of the timing and intensity of your workout.

What You'll Learn
- Strenuous exercise before bed may negatively impact sleep quality
- Moderate-intensity exercise can help you fall asleep faster
- Exercise raises your core body temperature, which may delay sleep
- Exercise timing depends on personal preference and sleep goals
- Aerobic exercise may be better for reducing nighttime awakenings
Strenuous exercise before bed may negatively impact sleep quality
Research indicates that high-intensity exercise close to bedtime can increase alertness and make it challenging to fall asleep. This is because strenuous physical activity stimulates the nervous system, raises the heart rate, and increases core body temperature, making it harder to fall asleep and potentially leading to more nighttime awakenings.
To avoid these negative impacts on sleep quality, it is advisable to leave at least 90 minutes between a vigorous workout and bedtime. This allows the body sufficient time to wind down, with endorphin levels and core body temperature returning to levels that are conducive to sleep. During this period, a proper cool-down routine involving gentle stretching and deep breathing can help calm the mind and soothe the body.
While the timing of exercise is important, the type of exercise and individual factors also play a role in sleep quality. Some people may find that any evening exercise keeps them up, while others may benefit from moderate aerobic or resistance workouts in the early evening to reduce nighttime awakenings. Ultimately, the key is to listen to your body and maintain a consistent exercise schedule.

Moderate-intensity exercise can help you fall asleep faster
Exercise has long been thought to help people sleep better. However, it was traditionally believed that exercising too late in the day could disrupt sleep. Recent studies have challenged this notion, suggesting that moderate-intensity exercise can help you fall asleep faster without compromising your sleep quality.
A 2020 study published in Sports Medicine examined 23 studies that evaluated sleep onset and quality in healthy adults who performed a single session of evening exercise. The researchers found that not only did evening exercise not negatively impact sleep, but it actually helped people fall asleep faster and spend more time in deep sleep. Similarly, a 2022 review found that low- to moderate-intensity workouts helped people fall asleep faster and increased slow-wave sleep, or deep sleep.
Moderate aerobic exercise increases the amount of slow-wave sleep you get, which refers to deep sleep when the brain and body rejuvenate. It can also help stabilize your mood and decompress the mind, which is important for transitioning to sleep. Additionally, regular exercise can promote relaxation, reduce anxiety, and normalize your internal clock.
However, it is important to be mindful of the timing and intensity of your workout. Experts recommend avoiding vigorous exercise within one to two hours before bedtime to allow time for your body to cool down and endorphin levels to decrease. Strenuous physical activity can stimulate your nervous system and raise your heart rate, making it difficult to fall asleep. Instead, opt for a brisk walk or another lower-intensity activity if you are exercising close to bedtime.

Exercise raises your core body temperature, which may delay sleep
To avoid this, it is recommended that you finish exercising at least one hour before bedtime. This will allow your body enough time to wind down and your core temperature to drop. For example, if you go to bed at 11 pm, finish your workout by 10 pm at the latest. The closer it is to your bedtime, the less vigorously you should exercise. So, if you only have an hour before bed, a lower-intensity activity like a brisk walk is a safer choice.
If you are unable to exercise earlier in the day, moderate-intensity exercises are still possible closer to bedtime without disrupting sleep. A 2020 study found that moderate aerobic exercise increases slow-wave sleep, and a 2022 review found that low- to moderate-intensity workouts helped people fall asleep faster and improved sleep quality.
While the time of day does not seem to matter for some people, others find that exercising too late interferes with their sleep. Therefore, it is important to listen to your body and know your limits. If you find that exercising before bed keeps you up at night, try shifting your workouts to earlier in the day.

Exercise timing depends on personal preference and sleep goals
Charlene Gamaldo, M.D., the medical director of Johns Hopkins Center for Sleep at Howard County General Hospital, encourages people to listen to their bodies and see how well they sleep in response to their workout timing. She notes that while there is solid evidence that exercise helps people fall asleep faster and improves sleep quality, the mechanism behind this relationship is not fully understood.
Recent studies have found that moderate-intensity exercise does not negatively impact sleep as long as it is completed at least one hour before bedtime. This allows time for endorphin levels and core body temperature to return to levels that are conducive to sleep. However, high-intensity exercise close to bedtime can raise core body temperature, heart rate, and adrenaline levels, making it difficult to fall asleep and potentially causing poor sleep quality.
To improve sleep health, it is recommended to aim for at least 30 minutes of moderate-intensity aerobic activity during the day or evening. Regular exercise is key to better sleep, and it can help treat sleep disorders. Additionally, a consistent exercise schedule is vital, as exercising at different times can cause sleep disturbances.
In summary, the best time to exercise depends on individual preferences and sleep goals. Moderate-intensity exercise is generally recommended, and it is best to avoid vigorous activity for at least one hour before bedtime to ensure a good night's sleep.

Aerobic exercise may be better for reducing nighttime awakenings
Exercise has long been thought to negatively impact sleep quality if performed too close to bedtime. However, recent studies have challenged this notion, suggesting that moderate-intensity exercise can be performed in the evening without disrupting sleep. In fact, it may even improve sleep quality.
That being said, vigorous exercise performed within an hour of bedtime can negatively impact sleep. Such exercise can stimulate the nervous system and increase the heart rate, core body temperature, and adrenaline levels, making it difficult to fall asleep. Thus, it is recommended to leave at least an hour between vigorous exercise and bedtime.
Aerobic exercise, in particular, has been found to improve sleep quality. It increases slow-wave sleep, which refers to deep sleep where the brain and body rejuvenate. Additionally, aerobic exercise can stabilize mood, reduce anxiety, and normalize the internal clock, all of which contribute to better sleep.
For those who frequently wake up during the night, adding an evening exercise routine may be beneficial. Specifically, light aerobic exercise performed in the early evening can help reduce nighttime awakenings. This is possibly due to the benefits of exercise being imparted without excessively raising body temperature, which can disrupt sleep.
In summary, while vigorous exercise should be avoided within an hour of bedtime, moderate-intensity aerobic exercise performed in the evening can improve sleep quality and reduce nighttime awakenings. Listening to your body and experimenting with different exercise schedules can help determine what works best for you.
