Can Exercise Help You Sleep Better?

If you’ve ever struggled to fall asleep, stay asleep, or wake up feeling rested, your nighttime routine may not be the only thing worth looking at.

Your circadian rhythm, physical activity, stress, light exposure, and daily habits all influence when your body feels alert and when it begins preparing for sleep.

And one surprisingly powerful tool for supporting better sleep happens long before your head hits the pillow:

Exercise.

What Is Your Circadian Rhythm?

Think of your circadian rhythm as your body's internal 24-hour clock.

It helps regulate your sleep-wake cycle along with physiological processes such as melatonin release, body temperature, and cortisol rhythms.

Light is the strongest environmental signal for this system, but physical activity can also influence circadian timing.

Research suggests that exercise can affect circadian physiology while also supporting sleep quality.

How Exercise Supports Better Sleep

The evidence here is strong.

A large 2025 systematic review and meta-analysis encompassing 81 randomized controlled trials and more than 6,000 participants found that exercise significantly improved both subjective sleep quality and objective sleep efficiency.

Regular physical activity may support sleep by:

• Improving sleep quality: People who exercise regularly tend to report better overall sleep.
• Supporting sleep efficiency: Exercise may help you spend more of your time in bed actually sleeping.
• Influencing circadian rhythms: Exercise can affect physiological rhythms involved in the sleep-wake cycle.
• Supporting mental well-being: Movement can help manage everyday stress and provide another foundation for healthy sleep.

The important point is that exercise isn't simply making you tired.

Regular movement can actually support the biological systems involved in healthy sleep.

What Type of Exercise Is Best?

There's no single workout you have to do to support better sleep.

In fact, several different forms of exercise have demonstrated benefits.

🏃 Aerobic Exercise

Examples: Walking, jogging, cycling, swimming

Aerobic exercise has some of the strongest evidence for improving sleep. A recent large meta-analysis found aerobic exercise particularly effective for improving objective sleep efficiency.

Try: A brisk walk, bike ride, swim, or run that fits naturally into your day.

💪 Resistance Training

Examples: Weights, squats, push-ups, resistance bands

Resistance exercise has also been studied as a way to support sleep quality.

You don't need an elaborate strength program. Consistently incorporating resistance exercise into your routine can be another way to support both physical health and healthy sleep.

🧘 Mind-Body Exercise

Examples: Yoga, Pilates, tai chi

These may be particularly interesting for people who have trouble mentally winding down.

A 2024 network meta-analysis of randomized controlled trials found significant improvements in sleep quality with Pilates, yoga, and traditional mind-body exercises compared with no exercise.

🌀 Mix It Up

You don't necessarily have to choose one.

Research also supports combinations of aerobic and resistance exercise, so the best approach may simply be one you can consistently maintain.

Does Exercise Timing Matter?

Yes but probably less than you've been told.

You've probably heard that exercising at night will keep you awake.

Research doesn't support such a simple rule.

Systematic reviews have found that evening exercise generally does not negatively affect subsequent sleep in healthy adults. Even high-intensity exercise performed a few hours before bedtime doesn't appear to substantially disrupt most sleep measures.

There is one important exception:

Very vigorous exercise ending close to bedtime may interfere with sleep for some people.

So instead of following a rigid rule, pay attention to how your own body responds.

Morning: A great option if it works with your schedule.

Afternoon or evening: Also perfectly reasonable for most people.

Right before bed: If intense exercise leaves you feeling wired, move your workout earlier.

Consistency matters more than chasing the “perfect” workout time.

Better Sleep Starts Before Bedtime

Sleep isn't something your body suddenly starts working on when you get into bed.

What you do throughout the day matters.

Regular exercise, consistent sleep and wake times, appropriate light exposure, nutrition, and your nighttime environment all contribute to healthy sleep.

That's why someone struggling with sleep should look beyond just their bedtime routine.

Where Does Scientific Sleep Support Fit?

Lifestyle should form the foundation of healthy sleep.

But sometimes you're already exercising, maintaining a regular routine, and creating a good sleep environment—and falling asleep or getting restful sleep is still difficult.

That's where targeted sleep support may complement those habits.

Scientific Sleep Support was designed with ingredients selected based on their researched roles in sleep onset and sleep quality.*

It's not meant to replace healthy sleep habits.

It's designed to support them.

The Bottom Line

If you're struggling with sleep, don't only focus on what happens in the hour before bed.

Look at your entire day.

Regular physical activity is one of the most well-supported lifestyle approaches for improving sleep quality, and you don't need an extreme exercise program to benefit.
