The Impact of Exercise on Sleep: Tips for Better Sleep, Rest and Recovery

In the pursuit of peak performance, two pillars stand above the rest: sleep and exercise. Exercise can improve sleep quality and enhance your overall health exercising for better sleep is essential for maintaining good sleep health... While most of us recognise the importance of staying active, the critical role of sleep in achieving optimal performance is often overlooked, especially regarding physical activity on sleep quality. The truth is, that sleep and exercise are deeply interconnected. Quality sleep enhances your ability to perform physically and mentally, while regular exercise can significantly improve the quality of your sleep.

Have you ever noticed how a good night’s sleep improves and makes your workout easier, or how a day of physical activity helps you sleep better? This isn’t just a coincidence-it’s backed by science. Sleep and exercise influence each other in powerful ways, creating a cycle that can either boost or hinder your overall performance and well-being.

Whether you’re an athlete, a fitness enthusiast, or simply looking to feel your best, understanding this relationship is crucial, especially with recent research highlighting the impact of exercise on sleep quality. We’ll explore how sleep and exercise work together, provide actionable tips to optimise both, and answer common questions like the best time to exercise and what happens when you don’t get enough sleep. Let’s get started and unlock the secrets to achieving peak performance!

How Exercise and Sleep Work Together

Think of exercise and sleep as partners in keeping your body healthy. Just like a car needs fuel and maintenance to run well, your body needs both activity and rest to perform at its best, impacting sleep onset. Research shows that people who exercise regularly, particularly aerobic exercise, generally fall asleep faster and improve sleep quality compared to those who don't. Meanwhile, getting good sleep helps your muscles recover and strengthen after exercise.

What Exercise Does for Your Sleep

When you exercise, several good things happen that help you sleep better, especially moderate aerobic exercise. Your body temperature rises during exercise and then drops afterwards, which can help trigger sleepiness, particularly after late-evening exercise. Exercise also helps reduce stress and anxiety, making it easier to relax and potentially improve sleep duration. The best part is that you don't need to be a professional athlete to get these benefits – even a daily walk can help improve sleep and enhance your overall well-being.

The Best Time to Exercise

When it comes to exercise, timing can play a significant role in performance and sleep quality, especially concerning sleep medicine and adults with insomnia. But is there a “best” time to work out? The answer depends on your goals, schedule, and individual chronotype-whether you’re a morning person, a night owl, or somewhere in between. Let’s break it down.

The Science Behind Timing For most people, the sweet spot for exercise is between 4:00 PM and 7:00 PM. During these hours, your body is at its peak performance level: your muscles are warm and flexible, your reaction time is fastest, and your strength is at its highest. However, everyone’s body clock is different, and your ideal workout time depends on your unique chronotype:

Morning people (early birds): Tend to perform best exercising around noon.
Average chronotypes: Peak around 4:00 PM.
Evening people (night owls): May struggle with sleep disorders like delayed sleep phase syndrome, impacting their health and daily activities due to misaligned sleep-wake cycles. However, they often perform best in the late evening, with peak performance typically around 7:00-8:00 PM.

Morning Workouts For early risers, exercising in the morning can be a great way to kickstart the day. Here’s why:

Boosts energy and mood: Morning exercise increases endorphin levels, leaving you feeling energised and positive, which may also reduce sleep complaints.
Improves consistency: Getting your workout done early reduces the chances of skipping it due to a busy schedule or lack of motivation later in the day.

However, morning workouts aren’t for everyone. If you’re not a morning person, forcing yourself to exercise early can feel like a chore, but late-night exercise might be a better fit for your schedule. Additionally, your muscles may be stiffer in the morning, so it’s important to warm up properly to prevent injury.

Evening Workouts For those who thrive later in the day, evening exercise has its own set of benefits:

Peak physical performance: Your body temperature and muscle strength tend to peak in the late afternoon or early evening, enhancing your performance.
Stress relief is essential, as high stress can negatively affect sleep quality: Exercise can help you unwind after a long day, reducing stress and preparing your mind for rest.
Better flexibility: Your muscles are warmer and more flexible later in the day, improving your range of motion and reducing the risk of injury.

The downside? Intense workouts too close to bedtime can interfere with your ability to fall asleep. If you prefer evening exercise, aim to finish at least 2-3 hours before bed to give your body time to cool down and wind down.

What’s the Best Time for You? The “best” time to exercise ultimately depends on your preferences, lifestyle and chronotype. Here’s how to decide: whether to incorporate exercise at night or stick to morning workouts for better sleep.

Morning larks: If you naturally wake up early and feel energised, schedule your workouts before work or school.
Night owls may benefit from exercise in the evening to help regulate their sleep patterns: If you’re more alert and motivated in the evening, opt for late afternoon or early evening workouts.
Somewhere in between: If unsure, experiment with different times and pay attention to how your body responds.

Remember, consistency is key. Whether you choose morning or evening, a regular exercise routine will yield the best results for your fitness and sleep health.

What Happens When You Don't Get Enough Sleep

Sleep is not a luxury-it’s a necessity for maintaining good health and preventing issues like obstructive sleep apnea. When you skimp on sleep, your body and mind pay the price. For athletes and fitness enthusiasts, the consequences of sleep deprivation can be particularly damaging. Let’s explore what happens when you don’t get enough sleep and how it impacts your exercise performance and overall health.

Short-Term Effects of Sleep Deprivation Even one or two nights of poor sleep can affect your body and mind. You might notice: improved sleep health and better focus after incorporating regular physical activity into your routine.

Your workouts feel harder than usual: Lack of sleep depletes your glycogen stores, leaving you feeling fatigued and sluggish during exercise.
You get tired more quickly if you experience insomnia or poor sleep quality, affecting your daily performance: Sleep deprivation reduces energy levels, making it harder to sustain intensity during workouts.
Your reaction time slows down: Poor sleep impairs cognitive function, increasing the risk of mistakes or injuries.
You feel more irritable: Sleep deprivation affects your mood, making it harder to stay motivated and focused.
You have trouble focusing, which can impact sleep and overall health: Lack of sleep impacts your ability to concentrate, which can hinder both physical and mental performance.

Long-Term Effects of Sleep Deprivation When sleep problems continue for weeks or months, the effects become more serious:

Increased risk of injury: Poor sleep impairs coordination and balance, making you more prone to accidents and injuries during exercise.
Slower muscle recovery: Without adequate sleep, your body struggles to repair muscle tissue, prolonging recovery time and increasing the risk of overtraining.
Reduced strength gains: Sleep deprivation limits the production of growth hormone, which is essential for muscle repair and growth.
Weakened immune system: Chronic lack of sleep compromises your body’s ability to fight off infections, making you more susceptible to illness.
Trouble controlling blood sugar can be exacerbated by insomnia, making it crucial to address both issues for better health and reducing sleep complaints: Sleep deprivation disrupts insulin sensitivity, energy levels and overall health.
Weight gain: Poor sleep disrupts hormones that regulate hunger (ghrelin and leptin), leading to increased appetite and cravings for unhealthy foods.
Mental health issues: Chronic sleep deprivation is linked to anxiety, depression, and mood disorders, which can further impact your motivation to exercise.

The Impact on Athletic Performance For athletes and fitness enthusiasts, sleep deprivation can be a major setback, as found that exercise on sleep quality is essential. Studies have shown that the effect of exercise on sleep is significant, leading to better sleep efficiency and overall health.

Sleep-deprived athletes experience a 20-30% reduction in aerobic capacity.
Reaction times can slow by up to 50%, affecting performance in sports requiring precision and quick reflexes.
Muscle recovery is significantly slower, increasing the risk of overtraining and injury.

Breaking the Cycle If you’re struggling with sleep deprivation, it’s important to take action before it takes a toll on your health and performance. Start by evaluating your sleep habits using the Sleep Quality Assessment Tool and free resources that can help identify potential sleep issues and improve sleep quality. For guidance, consider exploring resources that address sleep issues and the effect of exercise on sleep.

How Sleep Helps You Recover from Exercise

Sleep isn't just rest-it's when your body does some of its most important repair work, which is crucial for regular physical exercise. During deep sleep, your body:

Repairs Muscle: Your body releases growth hormone, which helps fix damaged muscle tissue and build stronger muscles.
Restores Energy: Your brain and muscles restock their energy supplies, like filling up a gas tank for the next day.
Fights Inflammation: Sleep helps calm inflammation that happens after exercise.
Strengthens Memory: Your brain practices new movement patterns you learned during physical exercise, helping you with sports and activities.

The Power of Naps

A well-timed nap can be like a mini battery recharge for your body. The best naps are:

20-30 minutes long
Taken in the early afternoon (between 1:00 PM and 3:00 PM)
Not too close to bedtime, especially if you have sleep apnea.

Naps can help you feel more alert and perform better during afternoon or evening workouts, especially if you didn't sleep well the night before.

Scientific Support Research published in the Journal of Sleep Research (2015) highlights the benefits of short naps for improving alertness and cognitive performance. For more details, you can read the full study here.

Travelling and Exercise: Dealing with Jet Lag

When you travel across time zones, your body's internal clock gets confused. This confusion, called jet lag, can affect sleep and exercise performance. Your body typically needs one day to adjust for each time zone you cross. So if you fly from New York to London (a 5-hour difference), it might take about 5 days to feel normal again.

To help your body adjust:

Start shifting your sleep schedule a few days before travelling
Get morning sunlight in your new location
Exercise at the right time for where you are
Be patient with your body as it adjusts

Sleep Tips for Better Exercise Performance

These simple changes can make a big difference in how well you sleep and exercise:

1. A consistent sleep schedule can significantly improve sleep quality and well-being. Your body thrives on routine. Going to bed and waking up at the same time every day—even on weekends—helps regulate your circadian rhythm. Aim for 7-9 hours of sleep per night.

2. Create a Sleep-Friendly Environment Your bedroom should be a sleep sanctuary. Consider the following recent research:

Keep it cool to promote better sleep health and enhance your exercise performance: The ideal sleep temperature is between 60-67°F (15-19°C).
Eliminate noise: Use earplugs or a white noise machine to block disturbances.
Darken the room: Invest in blackout curtains or an eye mask to create a pitch-black environment.

3. Avoid Stimulants Before Bed Caffeine, nicotine, and even heavy meals can interfere with your ability to fall asleep. Avoid consuming these at least 4-6 hours before bedtime. Instead, opt for a calming herbal tea or a light snack if you’re hungry.

4. Improving sleep quality can be essential for evening people (night owls) to feel more energised during the day. Incorporate Relaxation Techniques to enhance your total sleep time. Stress and anxiety are common sleep disruptors that can impact sleep onset. Try incorporating relaxation techniques into your bedtime routine, such as:

Meditation: Apps like Calm or Headspace can guide you through mindfulness exercises.
Deep breathing can enhance sleep health and improve your overall well-being: Practice slow, deep breaths to calm your nervous system.
Stretching or yoga: Gentle stretches can help relax your muscles and prepare your body for sleep.

5. Limit Screen Time Before Bed The blue light emitted by phones, tablets, and computers can suppress melatonin production, making it harder to fall asleep. Avoid screens at least an hour before bed, or use blue-light-blocking glasses if you must use devices.

6. Exercise Regularly-But Time It Right While exercise is great for sleep, timing matters. Intense workouts too close to bedtime can raise your heart rate and body temperature, making it harder to wind down. Aim to finish vigorous exercise at least 2-3 hours before bed. If you prefer evening workouts, opt for low-intensity activities like yoga or walking.

7. Track Your Sleep Patterns Understanding your sleep habits is the first step to improving them, particularly dealing with sleep apnea. Use tools like the American Academy of Sleep Medicine guidelines to enhance sleep health. Sleep Quality Assessment Tool and resources can help you understand the bidirectional relationship between exercise and sleep. Evaluate your sleep patterns and identify areas for improvement. This approach can help you make targeted changes to enhance sleep quality and sleep duration.

8. Seek Professional Help if Needed If you’ve tried everything and still struggle with sleep, consider seeking professional guidance. Sleep coaching can provide tailored strategies to overcome sleep challenges, and enhance performance and recovery.

Understanding Your Body's Daily Rhythm

Your body follows a 24-hour cycle that affects everything from your temperature to energy levels. Working with this natural rhythm, instead of against it, can help you get better sleep and physical exercise results.

During a typical day: Early Morning: Your body temperature starts rising Mid-morning: Coordination and reaction time improve Afternoon: Muscle strength and flexibility peak Evening: Body temperature peaks Night: Body temperature drops, making sleep easier

Making It All Work Together

The key to getting the most from sleep and exercise. Start by:

Tracking your energy levels throughout the day can help you find your best workout times, which may improve sleep quality and reduce the time it takes to fall asleep.
Setting a consistent sleep schedule that gives you 7-9 hours of rest may help in reducing sleep complaints.
Planning your harder workouts for when you know you'll be well-rested
Being flexible – sometimes life gets in the way, and that's okay, but maintaining a routine can help improve sleep efficiency.

Remember, small changes can lead to big improvements. You don't have to change everything at once. Pick one or two things to focus on, like setting a regular bedtime or adding a short walk to your daily routine, and build from there.
