Researchers have uncovered something fascinating in a narrative review published in Circulation Research: the pattern of our daily lives, influenced by the cycle of day and night, may have a significant impact on our heart's health. This discovery opens up new possibilities for supporting heart health.

Understanding the Review
The researchers analyzed how the timing of myocardial ischemia (heart events), heart function progression, and the effectiveness of various approaches are influenced by our internal biological clocks.
They focused on circadian molecular mechanisms within the heart and explored novel approaches aligned with our body's natural rhythms, such as light exposure, timing of medication (chronotherapy), and meal timings.
Key Findings
The review highlighted some fascinating insights into how our circadian rhythms may affect heart health. These include:
Circadian Rhythms and Heart Events: The severity of heart events can vary based on the time of day, with morning events potentially being more impactful than those occurring at night.
Influence on Risk and Recovery: Our internal body clock may significantly influence the risk and recovery process from cardiovascular concerns.
Light Exposure: This approach aligns with our circadian rhythms and uses intense light to support heart health, offering a non-invasive option.
Chronotherapy: This approach schedules heart health medication according to the body's natural rhythms to potentially enhance effectiveness and reduce side effects.
Meal Timing: Eating in sync with our circadian rhythms could support prevention and recovery outcomes for heart health, emphasizing the importance of not just what we eat, but when we eat.
Personalization of Approaches: The impact of circadian rhythms on heart health may vary by sex and age, suggesting that approaches may need to be customized to individual needs.
What This Means For You
- Optimized Medication Timing: By taking heart medications in alignment with your circadian rhythms—such as blood pressure pills in the morning—you may enhance their effectiveness and minimize side effects. This mindful timing uses the natural peak and trough cycles of your body’s biological clock to potentially improve outcomes.
- Light Exposure for Heart Health: Regular exposure to intense light may simulate the beneficial effects of natural sunlight, helping to reset your internal clock and support heart function. This can be an easy lifestyle adjustment to incorporate into your daily routine.
- Scheduled Meal Times: Eating your meals at consistent times that align with your circadian rhythm can help support heart health. For instance, having a hearty breakfast and avoiding late-night meals may reduce stress on your heart by syncing with your body’s natural metabolic cycles, thereby enhancing nutrient utilization and reducing nighttime heart strain.
Functional Lab Tests For Sleep Disturbances
Understanding your circadian rhythms and their impact on your heart might involve tracking your body's patterns or undergoing specific tests. Hormones like cortisol and melatonin follow circadian patterns, which may influence cardiovascular health. Testing these levels at different times can reveal disruptions in circadian rhythms.
Some examples of these tests offered through Rupa Health are: Diurnal Cortisol by Ayumetrix, UDH II by ZRT Laboratory and Comprehensive Melatonin Profile by Genova Diagnostics.

Key Takeaways
- Acknowledge your body's natural rhythms for better heart health. It's not just about what you do for your heart, but when you do it.
- Integrating light exposure into your routine could be a simple yet effective way to support your heart, aligning your body's rhythms with natural light patterns.
- Aligning your eating and medication schedules with your circadian rhythm could enhance treatment effectiveness and support your heart, underlining the powerful connection between your body clock and heart health.
