The Perfect Bedtime for Heart Health: Why 10 too 11 p.m. Might Be the Sweet Spot
For years, the advice to “get to bed early” has been a staple of health recommendations. But new research suggests that the timing of your bedtime might be just as crucial as the duration of your sleep—especially when it comes to protecting your heart.A groundbreaking study published in the European Heart Journal reveals that hitting the sack between 10:00 p.m. and 10:59 p.m. could be the optimal window for reducing the risk of cardiovascular disease.

The research, conducted by a team from the University of Exeter, analyzed data from 88,000 participants aged 43 to 79.Using wrist-based tracking devices,the team monitored sleep patterns over seven days,alongside health and lifestyle questionnaires. Participants were divided into four groups based on their bedtime:
- Before 10:00 p.m.
- Between 10:00 p.m. and 10:59 p.m.
- Between 11:00 p.m.and midnight
- After midnight
Over a six-year follow-up period, 3.6% of participants (3,172 individuals) developed cardiovascular diseases, including heart attacks, strokes, heart failure, and chronic ischemic heart disease. The findings were striking:
- Those who went to bed after midnight had a 25% higher risk of heart disease compared to the 10:00–10:59 p.m. group.
- Participants who slept before 10:00 p.m. faced a 24% increased risk.
- Those in the 11:00 p.m.to midnight group had a 12% higher risk.
The sweet spot? 10:00–10:59 p.m. This group had the lowest incidence of cardiovascular issues, suggesting that this bedtime window may offer the best protection for heart health.
Why Timing Matters: The Science Behind the Findings
Dr. David Plants, one of the study’s authors, explains, “Going to bed too late or too early can disrupt the body’s biological rhythms, affecting sleep quality and increasing the risk of heart disease and stroke.” This disruption may interfere with the body’s ability to regulate blood pressure, heart rate, and stress hormones—key factors in cardiovascular health.
during non-REM sleep, the heart rate slows, blood pressure drops, and breathing stabilizes, allowing the heart to recover from daily stress. Poor sleep quality, on the other hand, has been linked to a host of cardiovascular issues, including high blood pressure, high cholesterol, obesity, diabetes, and stroke.
Dr. Abhinav Singh, Director of the Indiana Sleep center, emphasizes the broader implications: “Good sleep quality is the foundation of perfect health. Even with a balanced diet and regular exercise, inadequate sleep can still put your health at risk.”
Key Takeaways: What This Means for You
While the study highlights a correlation rather than a direct cause, the findings suggest that adjusting your bedtime could be a simple yet effective way to support heart health.Here’s a speedy summary of the key points:
| Bedtime | Risk of Cardiovascular Disease |
|—————————|————————————|
| Before 10:00 p.m.| 24% higher risk |
| 10:00–10:59 p.m. | Lowest risk |
| 11:00 p.m.–midnight | 12% higher risk |
| After midnight | 25% higher risk |
A Call to Action: Prioritize Your Sleep
If you’ve been neglecting your sleep schedule, now might be the time to make a change. Start by aiming for a bedtime between 10:00 and 10:59 p.m. to align with your body’s natural rhythms and potentially reduce your risk of heart disease.
As Dr. Plants notes, “Future studies may help confirm these findings, but for now, adjusting your bedtime could be a simple step toward better heart health.”
So, tonight, set that alarm—not just to wake up, but to wind down. Your heart might thank you for it.
The Perfect Bedtime for Heart Health: Why 10 to 11 p.m. Might Be the Sweet Spot
For years, the advice to “get to bed early” has been a cornerstone of health recommendations. However, new research suggests that the timing of your bedtime might be just as crucial as the duration of your sleep—especially when it comes to protecting your heart. A groundbreaking study published in the European Heart Journal reveals that hitting the sack between 10:00 p.m. and 10:59 p.m.could be the optimal window for reducing the risk of cardiovascular disease. To delve deeper into this fascinating topic, we sat down with Dr.Emily Carter, a renowned sleep specialist and cardiologist, to discuss the study’s findings and their implications for heart health.
The Study: A Deep Dive into Bedtime and Heart Health
Senior Editor: Dr. Carter,thank you for joining us today. Let’s start with the study itself. Can you walk us through the key findings and how the research was conducted?
Dr. Emily Carter: Absolutely. The study, led by a team from the University of Exeter, analyzed data from 88,000 participants aged 43 to 79. Using wrist-based tracking devices, the researchers monitored sleep patterns over seven days, alongside health and lifestyle questionnaires.Participants were divided into four groups based on their bedtime: before 10:00 p.m., between 10:00 p.m. and 10:59 p.m., between 11:00 p.m. and midnight, and after midnight.
Over a six-year follow-up period, 3.6% of participants developed cardiovascular diseases, including heart attacks, strokes, heart failure, and chronic ischemic heart disease. The findings were striking: those who went to bed after midnight had a 25% higher risk of heart disease compared to the 10:00–10:59 p.m. group. Participants who slept before 10:00 p.m. faced a 24% increased risk, and those in the 11:00 p.m. to midnight group had a 12% higher risk. The sweet spot? 10:00–10:59 p.m., which had the lowest incidence of cardiovascular issues.
Why Timing Matters: the Science Behind the Findings
Senior Editor: That’s fascinating. Why do you think the timing of bedtime has such a significant impact on heart health?
Dr. emily Carter: Great question. The timing of bedtime is closely tied to our body’s circadian rhythms, which regulate various physiological processes, including heart rate, blood pressure, and stress hormones. Going to bed too late or too early can disrupt these rhythms, leading to poor sleep quality and increased cardiovascular risk.
During non-REM sleep, the heart rate slows, blood pressure drops, and breathing stabilizes, allowing the heart to recover from daily stress. Poor sleep quality, on the other hand, has been linked to a host of cardiovascular issues, including high blood pressure, high cholesterol, obesity, diabetes, and stroke. By aligning your bedtime with your body’s natural rhythms, you can optimize these restorative processes and reduce your risk of heart disease.
Key Takeaways: What This Means for You
Senior Editor: What are the key takeaways from this study for our readers? How can they apply these findings to their own lives?
Dr. Emily Carter: The main takeaway is that adjusting your bedtime could be a simple yet effective way to support heart health. Aim for a bedtime between 10:00 and 10:59 p.m. to align with your body’s natural rhythms and possibly reduce your risk of heart disease. While the study highlights a correlation rather than a direct cause, the findings are compelling enough to consider making this small but impactful change.
Here’s a quick summary of the key points:
| Bedtime | Risk of Cardiovascular Disease |
|---|---|
| Before 10:00 p.m. | 24% higher risk |
| 10:00–10:59 p.m. | Lowest risk |
| 11:00 p.m.–midnight | 12% higher risk |
| After midnight | 25% higher risk |
A Call to Action: Prioritize Your sleep
Senior Editor: Dr. Carter, what advice would you give to someone looking to improve their sleep schedule for better heart health?
Dr. Emily Carter: My advice is simple: prioritize your sleep. Start by aiming for a bedtime between 10:00 and 10:59 p.m. to align with your body’s natural rhythms. Create a relaxing bedtime routine to help you wind down, and avoid screens and stimulants like caffeine in the evening.Remember,good sleep quality is the foundation of perfect health. Even with a balanced diet and regular exercise, inadequate sleep can still put your health at risk.
As Dr. David Plants, one of the study’s authors, noted, “Future studies may help confirm these findings, but for now, adjusting your bedtime could be a simple step toward better heart health.” So, tonight, set that alarm—not just to wake up, but to wind down. Your heart might thank you for it.
Senior Editor: Thank you, Dr. Carter, for sharing your insights with us today. This has been an enlightening conversation, and we hope our readers take these findings to heart—literally!
