If you’ve ever spent the night tossing and turning, you know how frustrating and exhausting chronic insomnia can be. Up to 12% of Americans suffer from persistent sleep difficulties, often turning to cognitive behavioral therapy for insomnia (CBT-I) or sleep medications for relief. Some sleep aids often fail to mimic natural sleep cycles and come with unwanted side effects.
But what if there was an alternative that’s accessible, affordable, and beneficial for overall health? According to new research, exercise may be the answer.
Can Exercise Improve Sleep? What the Research Says
A recent meta-analysis of randomized controlled trials (RCTs) explored the impact of exercise on sleep quality. Researchers analyzed 19 studies involving 1,233 participants diagnosed with insomnia but without other sleep-related disorders. Unlike studies that combined exercise with other treatments, this review focused on exercise as a standalone intervention.
How Exercise Affects Sleep
The study assessed both objective (measured with sleep tracking devices) and subjective (self-reported) sleep outcomes:
✅ Improved Sleep Efficiency – Participants spent more of their time in bed actually sleeping.
✅ Less Wakefulness During the Night – People who exercised woke up less frequently after initially falling asleep.
✅ Higher Sleep Satisfaction – Even when objective measurements showed little change in sleep duration, participants felt like they slept better and woke up more refreshed.
However, exercise didn’t lead to falling asleep faster (sleep onset latency) or increased total sleep time. This means people weren’t necessarily sleeping longer, but their sleep quality improved significantly.
The Role of Exercise Intensity
The study also found that:
📌 Higher-intensity exercise produced greater improvements in sleep quality.
📌 Older adults and women benefited the most—potentially due to lower fitness levels at baseline.
Interestingly, most of the included studies used low-to-moderate intensity exercise (such as light walking or cycling). This suggests that even small amounts of movement can positively impact sleep—though higher-intensity workouts may lead to even better results.
Limitations and What We Still Don’t Know
While this study highlights the potential of exercise as a natural sleep aid, there are still some unanswered questions:
🔹 How much exercise is ideal? The study didn’t pinpoint a specific “exercise prescription” for insomnia.
🔹 Does exercise work better when combined with other treatments? More research is needed to explore how exercise interacts with CBT-I or other interventions.
🔹 Will people who are already active see additional sleep benefits? The study didn’t examine whether adding more exercise improves sleep for those already exercising regularly.
The Bottom Line: Move More, Sleep Better
When you’re exhausted from lack of sleep, working out might be the last thing you want to do. But staying sedentary can worsen the cycle of poor sleep and fatigue. The good news? Even light exercise can help improve sleep quality—so if you’re not active yet, starting small can still make a difference.
If you’re struggling with insomnia, consider adding consistent physical activity to your routine. Whether it’s a short walk, a yoga session, or strength training, movement can be a powerful, drug-free tool to support better sleep.
If pain is limiting your ability to exercise, seeing a chiropractor may help you regain mobility and comfort. Misalignments, muscle tension, or joint restrictions can make movement difficult, leading to further inactivity and worsening symptoms. Chiropractic care focuses on realigning the spine, reducing inflammation, and restoring function—helping you move pain-free. By addressing the root cause of discomfort, you can get back to your workouts, improve your sleep, and enhance your overall well-being.
