Exercise Can Help Improve Sleep
Regular exercise has been shown to have a positive impact on both sleep quality and duration. Physical activity creates more adenosine, a chemical in the brain that makes us feel sleepy.12 The harder we exercise, the more adenosine is produced, driving the body’s need for sleep12. Exercise also helps maintain a healthy circadian rhythm, priming the body for better sleep at night13.
While high-intensity exercise close to bedtime may delay sleep onset12, moderate exercise throughout the day or evening can improve sleep quality and efficiency12. In fact, a 2021 review found that regular physical activity improves sleep patterns in adults with insomnia and obstructive sleep apnea symptoms13. Additionally, a 2020 randomized controlled trial showed that high-intensity interval training may improve sleep quality for middle-aged adults with low physical activity levels13.
Exercise Creates More Adenosine in the Brain
The more we exercise, the more adenosine our bodies produce, which in turn makes us feel sleepy.12 This increase in adenosine levels can help us fall asleep faster and experience better quality sleep throughout the night12. Furthermore, a 2021 study suggested that exercising vigorously in the evenings might enhance slow-wave sleep, improving overall sleep quality13.
While the relationship between high-quality sleep and physical activity levels is established, research has not definitively proven that better sleep leads to an increase in physical activity levels12. However, it is clear that incorporating regular exercise into your routine can have a significant positive impact on your sleep patterns and overall sleep health13.
“Exercise relieves stress and anxiety, building sleep pressure and altering body temperature to regulate the sleep/wake cycle.”14
In conclusion, making exercise a consistent part of your lifestyle can be a powerful tool for improving your sleep quality and duration. By understanding the connection between exercise and adenosine production, you can optimize your workout routine to support better sleep and overall health121314.

Sleep and Muscle Recovery
Adequate sleep is crucial for optimal muscle recovery and growth. During sleep, the body produces growth hormone, which is essential for repairing and building muscle tissue29. The National Sleep Foundation recommends adults get between 7 and 9 hours of sleep per night for optimal recovery from exercise29. Increasing sleep time by just one hour per night is equivalent to having an extra night’s worth of sleep over a week29. Growth hormone, crucial for tissue repair, is primarily produced during stage 3 of non-rapid eye movement (NREM) sleep, emphasizing the importance of adequate sleep for muscle regeneration.
Without sufficient sleep, the body is unable to fully recover and adapt to exercise, potentially leading to decreased muscle strength and endurance29. One gram of glycogen in muscle cells can store three to four grams of water. This process occurs during sleep, contributing to muscle growth and recovery29. Insufficient sleep can lead to higher levels of catabolic hormones, hindering tissue repair and muscle growth29. Missing out on sleep can result in heightened sympathetic nervous system activity and elevated cortisol levels, impacting muscle growth and overall exercise performance.
Ensuring sufficient sleep duration and quality is vital for athletes and fitness enthusiasts to maximize the benefits of their training and reach their performance goals29. Inadequate sleep can cause a delay in reflexes, poor judgement, and increase the risk of training injuries, highlighting the importance of sleep for exercise safety29. Outside of traumatic injury, illness is the second leading cause of missed playing time for athletes, emphasizing the crucial role of sleep in promoting immune function29. Overtraining due to excessive exercise and insufficient sleep can hinder fitness goals, potentially leading to injuries that impede physical activity.
Planning workouts based on the quality of sleep one can achieve can optimize exercise performance, with high-intensity workouts best scheduled following nights of ample rest29.
| Key Benefits of Sleep for Muscle Recovery | Supporting Evidence |

| Replenishment of muscle glycogen and restoration of energy sources occur during quality sleep, contributing to muscle recovery. | 30 |
| Sleep and muscle growth are closely linked, with studies showing that sleep deprivation can lead to loss of muscle mass. | 30 |
The importance of sleep for muscle recovery and athletic performance is well-documented31. One night of sleep deprivation decreases treadmill endurance performance31. Sleep interventions have been designed to improve athletic performance and recovery31. Effects of one night’s sleep deprivation on anaerobic performance the following day have been studied31. Trends and factors associated with insomnia and sleep apnea in all United States military service members from 2005 to 2014 have been analyzed31. The acute effects of twenty-four hours of sleep loss on the performance of national-caliber male collegiate weightlifters were investigated31. Altered sleep-wake cycles have been linked to physical performance in athletes31. The role of a short post-lunch nap in improving cognitive, motor, and sprint performance in participants with partial sleep deprivation has been explored.
“Ensuring sufficient sleep duration and quality is vital for athletes and fitness enthusiasts to maximize the benefits of their training and reach their performance goals.”
Impact of Sleep on Weight and Obesity
Adequate, quality sleep is a crucial factor in maintaining a healthy weight and preventing obesity. Research has shown that sleep deprivation can have a significant impact on the body’s hormones that regulate appetite, leading to increased hunger and cravings for unhealthy, high-calorie foods.32 Sleep-deprived individuals are also more likely to make poorer dietary choices and be less physically active during the day32.
Chronic sleep loss has been linked to a higher risk of obesity and other metabolic disorders32. For instance, children who do not get enough sleep increase their risk of becoming overweight or obese.32 Additionally, children who go to bed later have worse diet quality, consuming more nutrient-poor foods and fewer fruits and vegetables compared to those who go to bed earlier.32
The connection between sleep and weight management is further highlighted by the fact that obesity is seven times more common in individuals with obstructive sleep apnea, a condition that can disrupt sleep.32 Furthermore, obesity increases the risk of developing conditions like gastroesophageal reflux disease (GERD) and asthma, which can also contribute to sleep disturbances.32
Interestingly, exercise can improve sleep quality and reduce symptoms in conditions like obstructive sleep apnea, independent of weight loss.32 Similarly, maintaining a balanced diet can potentially improve sleep quality.32 By prioritizing adequate, quality sleep along with a healthy diet and regular exercise, individuals can better manage their weight and reduce the risk of obesity-related health issues323334.
“Sleep loss is associated with growth hormone deficiency and elevated cortisol levels, both linked to obesity.”32
The impact of sleep on weight and obesity is a complex and multifaceted issue. Numerous studies have highlighted the various ways in which sleep deprivation can contribute to weight gain and obesity3334.
- Restricted sleep duration causes a greater tendency to select high-calorie foods, increasing the risk of weight gain32.
- Adults not getting sufficient sleep engage in less exercise compared to those who do, possibly due to sleepiness and fatigue during the day32.
- Obstructive sleep apnea, a condition that can disrupt sleep, is seven times more common in individuals who are obese32.
- Obesity increases the risk of developing conditions like gastroesophageal reflux disease (GERD) and asthma, which can also contribute to sleep disturbances32.
To maintain a healthy weight and prevent obesity, it is essential to prioritize quality sleep, in addition to a balanced diet and regular exercise323334.
Sleep Disorders and Exercise
Maintaining a healthy sleep schedule is crucial for overall fitness and well-being, but for some individuals, sleep disorders can pose a significant challenge35. Research conducted in the United Kingdom included over 92,000 adults between 40 and 73 years old, and participants were monitored over a period spanning from 2013 to 2015 to track exercise and sleep patterns35. The findings revealed that regular exercise was associated with reduced risk of death, even in cases where individuals slept less than six hours per night35. Completing 150 minutes of moderate or vigorous physical activity per week was highlighted as potentially offsetting health risks related to inadequate sleep35. Engaging in physical activity, such as short walks or stationary bike rides, was recommended as beneficial even in small doses.
Insomnia and Exercise
Individuals struggling with insomnia often find it difficult to fall asleep or stay asleep, leading to daytime fatigue and reduced exercise performance36. Research has shown that sleeping less than six hours a night harms more than just the brain for most people, as it is linked with a fivefold increased risk for stroke and double the risk for heart disease and death when combined with other common conditions like diabetes or high blood pressure36. However, studies have demonstrated that exercise can be as effective as prescription sleep medication in improving sleep quality37. Physical activity increases the body’s sleep drive, promoting better sleep at night, and the brain’s release of feel-good chemicals during exercise can combat stress and anxiety, which can contribute to insomnia.
Sleep Apnea and Exercise
Sleep apnea is a condition characterized by interrupted breathing during sleep, which can impair exercise capacity and recovery36. People with higher levels of physical activity and who slept between six and eight hours per night had better cognitive function as they aged, while being less physically active and sleeping poorly were independently associated with worse cognitive performance over time36. Engaging in regular exercise has been shown to help improve the symptoms of sleep apnea, underscoring the importance of addressing both sleep and physical activity for overall health.
Restless Legs Syndrome and Exercise
Restless legs syndrome, a condition that causes an uncomfortable urge to move the legs, can disrupt sleep and negatively affect exercise routines36. Sleeping less than six hours a night was linked with a faster rate of cognitive decline over time, and highly active people in their 50s and 60s who slept on average less than six hours a night had the same cognitive levels as people who didn’t exercise after 10 years36. However, research has shown that regular exercise can help improve the symptoms of restless legs syndrome, providing a potential avenue for managing this sleep disorder.
In conclusion, addressing sleep disorders and incorporating regular exercise can have a significant impact on overall fitness and health. By understanding the connections between sleep, exercise, and conditions like insomnia, sleep apnea, and restless legs syndrome, individuals can take proactive steps to optimize their sleep and physical activity for long-term well-being.

Ideally, both sleep and exercise should be prioritized for optimal health and fitness. However, when time is limited, sleep should take priority, especially if sleep deprivation has been an issue. Without sufficient sleep, the body is unable to properly recover and adapt to exercise, undermining the benefits of physical activity. Skipping a workout is better than skipping sleep, as sleep-deprived individuals tend to have poorer exercise performance and increased risk of injury. While exercise is important, getting the recommended 7-8 hours of sleep per night should be the primary focus for improving overall health and fitness.
How can you improve sleep quality and duration?
Improving sleep quality and duration can be achieved through various lifestyle changes. Avoiding large meals and caffeine too close to bedtime can help the body wind down and prepare for sleep. Regular exercise during the day can increase adenosine levels in the brain, promoting sleepiness. Exposure to natural light, particularly in the morning, can also help regulate the body’s circadian rhythm for better sleep. Incorporating these sleep-promoting habits into your daily routine can lead to improved sleep, which in turn supports exercise recovery and overall health.
What is the recommended sleep duration for adults?
According to sleep experts, most healthy adults require 7-8 hours of sleep per night for optimal health and performance. However, over 30% of Americans are not getting the recommended amount of sleep. Insufficient sleep has been linked to a variety of health problems, including increased risk of chronic diseases, reduced cognitive function, and impaired exercise performance. Prioritizing proper sleep duration is crucial for maintaining physical and mental wellbeing, as well as achieving fitness goals.
How does sleep impact muscle recovery and growth?
Sleep plays a crucial role in muscle recovery and growth. During sleep, the body produces growth hormone, which is essential for repairing and building muscle tissue. Without adequate sleep, the body is unable to fully recover and adapt to exercise, potentially leading to decreased muscle strength and endurance. Ensuring sufficient sleep duration and quality is vital for athletes and fitness enthusiasts to maximize the benefits of their training and reach their performance goals.
How does sleep deprivation affect weight and obesity?
Sleep deprivation can have a significant impact on weight and obesity. Lack of sleep affects the body’s hormones that regulate appetite, leading to increased hunger and cravings for unhealthy, high-calorie foods. Sleep-deprived individuals are also more likely to make poorer dietary choices and be less physically active during the day. Chronic sleep loss has been linked to a higher risk of obesity and other metabolic disorders. Prioritizing adequate, quality sleep is an important factor in maintaining a healthy weight and preventing obesity, in addition to a balanced diet and regular exercise.
How do sleep disorders affect exercise and fitness?
Sleep disorders can have a significant impact on exercise and overall fitness. Individuals with insomnia often struggle to fall asleep or stay asleep, which can lead to daytime fatigue and reduced exercise performance. Sleep apnea, a condition characterized by interrupted breathing during sleep, can also impair exercise capacity and recovery. Restless legs syndrome, which causes an uncomfortable urge to move the legs, can disrupt sleep and negatively affect exercise routines. However, research has shown that regular exercise can help improve the symptoms of these sleep disorders, underscoring the importance of addressing both sleep and physical activity for overall health.
How does the timing of exercise impact sleep?
The timing of exercise can impact sleep quality and duration. Morning or afternoon exercise may be more beneficial for sleep, as it helps regulate the body’s circadian rhythm and prepares the body for better sleep at night. High-intensity exercise close to bedtime, however, may delay sleep onset due to increased heart rate and body temperature. For those who struggle with sleep, it’s recommended to avoid vigorous exercise in the evening and instead opt for lower-intensity activities like yoga or light stretching. Experimenting with different exercise schedules can help individuals find the optimal timing that supports both their fitness goals and sleep quality.
