Have you ever noticed how you feel more tired after a long day of playing or exercising? Well, that’s not just your body being tired—your brain benefits too. Recent studies have shown that regular exercise can help improve sleep, even for people who have trouble sleeping.
A recent study showed that exercise can help people sleep better, whether or not they have sleep problems. The research explains that exercise affects sleep in different ways depending on things like your age, fitness level, the type of exercise you do, and when you do it.
Why Timing Matters
When you think about exercise and sleep, you might wonder when’s the best time to exercise. The truth is, when you exercise matters. Exercise helps most people sleep better if it’s done at the right time. Moderate exercise in the early evening can improve your sleep, but if you exercise too close to bedtime, it might actually make it harder to fall asleep.
Here’s why: when you exercise, your body’s temperature goes up. If you exercise too late, your body might still be too warm to relax, which makes it harder for your brain to produce melatonin, the hormone that helps you fall asleep.
Moderate evening exercise may be okay for healthy young people, but if you’re older or have sleep issues, it might be better to exercise earlier in the day.
Types of Exercise That Help Sleep
Exercise comes in many different forms, and each has its own benefits. Let’s break down the types of exercise and how they help with sleep:
- Aerobic Exercise – These activities make your heart beat faster and make you breathe harder. Examples include walking, swimming, and cycling. Aerobic exercise helps improve your heart health and overall fitness, which can lead to better sleep.
- Anaerobic Exercise – This includes things like weightlifting and sprinting. Anaerobic exercise focuses on building strength and muscle. While it’s great for muscle building, it doesn’t seem to have the same effects on sleep as aerobic exercise.
- Stretching – Stretching exercises can help you feel more relaxed and improve flexibility. However, the research is mixed on whether stretching alone can prevent sleep problems.
- Dynamic Exercise – This type involves moving your joints, like during yoga or dance. It helps improve blood flow and lower blood pressure, which can help you relax and sleep better.
The Benefits of Exercise
Exercise isn’t just about feeling good while you’re doing it. It has long-lasting benefits that affect both your mind and body. Here’s why exercise is so powerful:
- Regulates Weight – Regular exercise helps control your weight by balancing the calories you take in and burn. This can prevent obesity, which can be linked to poor sleep.
- Reduces Risk of Health Problems – Exercise helps lower your chances of getting diseases like diabetes, high blood pressure, and depression, which are all linked to poor sleep.
- Improves Heart Health – Exercise strengthens your heart and helps it recover faster, which is important for sleep quality.
- Boosts Mood – When you exercise, your body releases endorphins (the “feel-good” hormones), which help you feel happier and more relaxed.
- Helps Sleep – Exercise reduces stress, lowers anxiety, and increases melatonin levels, all of which are important for falling asleep and staying asleep.
Exercise helps make sleep more efficient, which means you spend more time actually sleeping and less time tossing and turning. Here’s how:
- Faster Sleep Onset: People who exercise tend to fall asleep faster because their bodies and minds are more relaxed.
- Longer Sleep Time: Regular exercise can help you stay asleep longer.
- Better Sleep Quality: With regular exercise, people report better sleep quality, which means deeper, more restful sleep.
- Improves Sleep Habits: Regular exercise helps people get into a consistent sleep schedule, which makes it easier to fall asleep and wake up at the right times.
Exercise isn’t just for people who sleep well—it can also help people who have trouble sleeping. Let’s look at some common sleep problems and how exercise can help:
• Insomnia: Insomnia is when you can’t fall asleep or stay asleep. Regular exercise, like aerobic exercise, can help you sleep better by reducing the time it takes to fall asleep, making your sleep deeper, and helping you wake up less during the night.
• Restless Leg Syndrome (RLS): RLS causes a strong urge to move your legs, making it difficult to fall asleep. Exercise helps by improving blood circulation, which reduces the symptoms of RLS.
• Sleep Apnea: This is a serious condition where your breathing stops and starts during sleep. Regular exercise, especially when combined with weight loss, can reduce the symptoms of sleep apnea and help you sleep better.
How Much Exercise Do You Need?
The timing and amount of exercise you do matters for sleep. To get the most benefit, exercise should be done regularly. But, how much exercise do you need?
• Moderate Exercise: For the best results, try to exercise for at least 30 minutes most days of the week. This could be as simple as walking, swimming, or cycling. Make sure to finish exercise at least 4 hours before bed to avoid disrupting your sleep.
• Intensity: If you’re doing intense workouts, like running or weightlifting, it’s important to do them earlier in the day. Intense exercise too close to bedtime can make it harder for you to fall asleep.
The Best Time to Exercise for Better Sleep
If you’re thinking about exercising later in the day, it’s important to time it right. As a general rule, it’s best to finish moderate exercise at least 4 hours before bed to improve your sleep quality. Light exercise done closer to bedtime may be okay for younger people, but it can still have a mild effect on sleep. If you’re older, you should aim for earlier workouts to ensure good rest.
Conclusion: Can Exercise Replace Sleep Medication?
Exercise has proven to be a powerful tool in improving sleep quality. In fact, some studies suggest that regular exercise can improve sleep just as much as sleep medications—but with fewer side effects. It’s a natural way to help treat sleep problems like insomnia, restless leg syndrome, and sleep apnea.
Exercise should be seen as a key part of your sleep routine, not just something to do to get fit. So, if you’re struggling with sleep, consider adding regular exercise to your day. Whether it’s a walk in the park, a swim in the pool, or cycling around the neighborhood, exercise can make a huge difference in how well you sleep.
Start small and gradually make it a regular part of your routine. Over time, you’ll notice a difference—not just in how you feel during the day, but in how well you sleep at night.
