Coffee lovers worldwide may want to rethink their caffeine schedules. According to a recent study published in the European Heart Journal, drinking coffee in the morning could significantly benefit heart health compared to sipping it throughout the day. The research, led by Dr Lu Qi, Director of the Tulane University Obesity Research Centre, provides compelling insights into how coffee timing affects cardiovascular well-being and overall mortality risk.
The Study at a Glance
The study analyzed data from over 40,000 adults who participated in the National Health and Nutrition Examination Survey (1999–2018) in the U.S. Participants detailed their coffee consumption habits, including the amount they drank and the times of day they enjoyed their brew. Over a follow-up period of nearly 10 years, researchers recorded 4,295 deaths, of which 1,268 were due to cardiovascular disease. The findings were revealing:
- Morning coffee drinkers had a 16% lower risk of death from any cause.
- They also exhibited a 31% lower risk of dying from heart disease compared to non-coffee drinkers.
- Individuals who drank coffee throughout the day did not share the same reduced risks.
Why Morning Coffee May Be Better
Dr Qi explained that the timing of coffee consumption could influence the body’s circadian rhythm, the natural 24-hour cycle that regulates sleep, hormones, and metabolism. Drinking coffee later in the day might disrupt this rhythm, affecting melatonin production and other hormonal balances critical for health.

“Coffee consumed later in the day may interfere with the body’s natural rest cycle, potentially affecting cardiovascular health outcomes,” noted Dr. Qi. This disruption could lead to higher inflammation levels and increased blood pressure, both of which are linked to heart disease.
Interestingly, morning coffee drinkers in the study tended to consume less coffee overall and were more likely to drink tea or caffeinated sodas compared to those who drank coffee all day.
What This Means for Coffee Drinkers
While the study does not conclusively prove that coffee itself is responsible for the health benefits, the findings align with growing evidence about the importance of circadian health. Drinking coffee earlier in the day aligns with the body’s natural rhythm and may reduce the potential cardiovascular risks associated with disrupted sleep and hormonal imbalances.

The Case for More Research
Dr Qi emphasized that additional clinical trials are necessary to confirm whether shifting coffee consumption to earlier hours could be a practical recommendation for heart health. For now, the research highlights the potential benefits of timing your coffee intake to maximize health benefits.
Practical Tips for Coffee Lovers
- Start Early: Enjoy your first cup of coffee in the morning to align with your body’s natural rhythm.
- Limit Late-Day Caffeine: Avoid coffee in the afternoon and evening to prevent interference with sleep and hormone regulation.
- Moderation Matters: Keep your coffee intake moderate, as excessive caffeine can have adverse effects.
Bottomline
While coffee remains a beloved beverage for many, this study underscores the importance of timing your caffeine intake. Morning coffee drinking appears to have distinct advantages for heart health, potentially reducing the risk of cardiovascular disease and overall mortality. By making simple adjustments to your coffee routine, you could not only enjoy your favorite brew but also protect your heart in the process.
