Exercise is an important part of sleep hygiene and can improve sleep quality and duration. However, the best time of day to exercise for optimal sleep has been a subject of debate. While some studies suggest that morning exercise helps with weight loss and appetite regulation, others indicate that afternoon or evening workouts may be more effective for improving metabolism. Recent studies have also found that moderate-intensity exercise does not negatively impact sleep quality as long as it is completed at least one hour before bedtime. On the other hand, strenuous physical activity close to bedtime may disrupt sleep.

Morning exercise may help with appetite regulation and energy balance, ultimately supporting weight loss
Morning exercise is beneficial for individuals with obesity and can help with weight loss. It can regulate your appetite by reducing ghrelin, the hunger hormone, and increasing satiety hormones, like peptide YY and glucagon-like peptide-1. Morning workouts can also improve how your brain responds to food cues. For example, in a study where women who exercised in the morning showed a reduced brain response to food photos compared to when they didn't exercise.
Exercising in the morning can also be advantageous for your body's hormonal fluctuations. Cortisol, often called the stress hormone, peaks around 8 a.m. and drops in the evening. Therefore, exercising early can help you feel more energized throughout the day and improve your focus and concentration. Morning exercise may also enhance weight loss independently of daily physical activity levels, as it can impact energy intake behaviours and circadian influences.
Additionally, morning exercise can improve your sleep quality. Light exposure early in the day may help increase melatonin levels at night, aiding in better sleep. However, it is important to note that exercising too late in the day can interfere with sleep for some people. While recent studies suggest that moderate-intensity exercise won't affect sleep if completed at least an hour before bedtime, vigorous workouts too close to bedtime may negatively impact sleep quality.
In summary, morning exercise can help with appetite regulation, energy balance, and sleep, ultimately supporting weight loss. It is important to listen to your body and choose the time of day that works best for you to exercise.

Exercising before bed may affect sleep, but avoiding rigorous exercise can help
Exercise is beneficial for the body and mind, and it can also help you get a good night's sleep. However, for some people, exercising too late in the day can interfere with sleep quality. While the exact mechanism underlying the relationship between exercise and sleep remains unknown, studies have shown that moderate aerobic exercise increases slow-wave sleep, which refers to the deep sleep phase when the brain and body rejuvenate.
Traditionally, experts have advised against exercising at night to maintain good sleep hygiene. However, recent studies have challenged this notion, suggesting that evening workouts may not negatively impact sleep quality. Specifically, moderate-intensity exercise, when completed at least one hour before bedtime, does not disrupt sleep. In fact, it can help individuals fall asleep faster and improve overall sleep quality.
It is important to note that vigorous or strenuous exercise close to bedtime may have adverse effects on sleep. High-intensity interval training, for example, has been associated with longer sleep onset and poorer sleep quality. Strenuous physical activity can stimulate the nervous system and elevate the heart rate, making it challenging to fall asleep. Therefore, it is generally recommended to avoid vigorous exercise within one to two hours of bedtime.
To optimize sleep, it is advisable to maintain a consistent sleep schedule, create a relaxing bedtime routine, and limit exposure to electronic devices and substances like nicotine, alcohol, and caffeine, which can disrupt sleep. Additionally, incorporating light to moderate-intensity exercises, such as stretching or yoga, into your evening routine may promote better sleep by helping you unwind and relax.
Ultimately, the relationship between exercise and sleep is highly individual. While research provides valuable insights, listening to your body and understanding your personal preferences are crucial. The best time to exercise is when it works for you, and choosing an activity you enjoy will help you maintain a consistent exercise routine.

Recent studies suggest that moderate-intensity exercise won't impact your sleep if completed at least 1 hour before bedtime
For a long time, common wisdom held that exercising at night was detrimental to sleep. However, recent studies have found that moderate-intensity exercise won't impact your sleep if completed at least one hour before bedtime. In fact, moderate-intensity exercise can increase sleep quality by reducing sleep onset and decreasing the amount of time spent awake in bed.
Traditionally, experts have recommended avoiding vigorous activity for at least one to two hours before bedtime. This is because high-intensity exercise can increase your core body temperature, stimulating your nervous system and raising your heart rate, which can make it difficult to fall asleep. Additionally, high-intensity exercise can induce a higher level of endorphin activity in the brain, which may keep some people awake.
However, moderate-intensity exercise can be beneficial for sleep. Studies have shown that people who engage in at least 30 minutes of moderate aerobic exercise may see an improvement in their sleep quality that same night. Moderate aerobic exercise increases the amount of slow-wave sleep, or deep sleep, that one gets, giving the brain and body a chance to rejuvenate.
It's important to note that everyone is different, and the best time to exercise is the time that works for you. While moderate-intensity exercise may not impact your sleep if completed at least one hour before bedtime, vigorous workouts in the hour leading up to bed can affect sleep efficiency and total sleep time.

Morning workouts can help you fall asleep faster at night by lowering levels of orexin, a neurotransmitter that promotes wakefulness
Morning workouts are beneficial for a good night's sleep, and this is partly due to the lowering of orexin levels. Orexin, also known as hypocretin, is a neurotransmitter that regulates arousal, wakefulness, and appetite. It is considered the most significant stimulator of wakefulness, and while its role is a relatively recent discovery, it is believed to be central to productive human functioning and a good mood.
Research has shown that exercising in the morning or early in the day can help improve sleep quality. While the exact mechanism is not fully understood, it is known that moderate aerobic exercise increases slow-wave sleep, which refers to deep sleep when the brain and body rejuvenate. Morning workouts can also help stabilize your mood and decompress the mind, aiding in the natural transition to sleep. Additionally, exercising in the morning ensures that you give your body enough time to wind down before bed. It is recommended to finish working out at least one hour before bedtime, and preferably 90 minutes if possible.
Orexin levels in the body are influenced by various factors, including diet and exercise. Consuming less sugar and carbohydrates can help increase orexin levels, as high glucose levels prevent its production. Intermittent fasting and consuming fermented foods that contain lactic acid can also positively impact orexin production. On the other hand, exercising increases the acidification of the blood, which leads to higher orexin levels. Therefore, morning workouts can contribute to increased orexin levels, promoting wakefulness and alertness during the day.
It is important to note that everyone's body is different, and the best time to work out depends on individual preferences and how well one sleeps in response to exercise timing. While morning workouts are generally recommended, some people may find that they can exercise in the evening without negatively impacting their sleep. However, it is advised to avoid vigorous or high-intensity activities close to bedtime, as they can stimulate the nervous system and raise the heart rate, making it challenging to fall asleep.
