If you struggle with sleep, you have probably tried many fixes. Magnesium, meditation apps, no screens after 8 p.m. And somewhere in between, someone always tells you to exercise more. But what if the real secret is doing two of these things together?
A new study suggests that combining exercise with sleep coaching works better than either one on its own. The results were surprisingly clear, and they could change how we think about sleep health.
What the researchers did
Researchers followed 112 women between the ages of 18 and 30. All of them had one thing in common: poor sleep quality. The women were split into four groups for eight weeks.
The first group did high-intensity circuit training three times per week. These were short, efficient workouts using bodyweight moves that combine strength and cardio. The second group received sleep coaching. This included personal guidance and a digital program based on cognitive behavioral therapy for insomnia, which targets the habits and thoughts that disturb sleep.
The third group combined both strategies: regular high-intensity workouts plus structured sleep coaching. The final group did not change their routine at all.
How the results were measured
To track results, the team used both subjective and objective measures. Participants reported how they felt about their sleep. Researchers also used wearable devices to capture sleep efficiency, how often people woke up, and how restless they were at night. They even checked markers of heart health, including cholesterol levels.
The group that combined exercise and sleep coaching saw the biggest improvement. This supports a simple idea: physical activity and good sleep habits work as a team. Exercise can tire the body in a healthy way, while coaching fixes the habits that keep the mind awake.
What this means for you
If you want better sleep, do not treat exercise and sleep habits as separate projects. Try a short workout a few times per week and build a calm bedtime routine. Small, steady changes on both fronts may give you the rest you have been missing.
The heart connection
The study also looked at heart health. The team measured cholesterol levels in all four groups. Exercise is already known to support healthy cholesterol and blood pressure. Good sleep may boost these benefits even further.
Many earlier studies have linked poor sleep to a higher risk of heart problems. When you sleep badly night after night, your body stays in a state of stress. Combining regular workouts with a calm bedtime routine may help on two fronts at once: a stronger body and a calmer mind.
