The Best Time to Drink Coffee for Heart Health, According to a New Study
A new study published in the European Heart Journal reveals that the timing of coffee consumption plays a crucial role in its health benefits. Researchers from Tulane University and Harvard T.H. Chan School of Public Health found that drinking coffee in the morning is linked to a significantly lower risk of cardiovascular disease and all-cause mortality compared to consuming coffee throughout the day.
The study analyzed data from over 40,000 U.S. adults and identified two distinct coffee-drinking patterns. The first group, labeled as morning coffee drinkers, primarily consumed their coffee between 4 a.m. and 11:59 a.m. The second group, described as all-day coffee drinkers, consumed coffee continuously throughout the day.
According to the findings, morning coffee drinkers had a 31 percent lower risk of dying from heart disease and a 16 percent lower risk of all-cause mortality compared to those who drank coffee at different times throughout the day. Researchers suggest that drinking coffee later may disrupt circadian rhythms, leading to negative effects on blood pressure, inflammation, and overall cardiovascular health.
Cardiovascular disease remains the leading cause of death in the United States, making insights into dietary habits and their impact on longevity particularly relevant.
The Impact of Coffee on Blood Pressure
Caffeine affects individuals differently, with some experiencing a temporary rise in blood pressure and heart rate. However, the Mayo Clinic states that regular coffee consumption does not cause a long-term increase in blood pressure or an elevated risk of heart disease. Habitual coffee drinkers develop a tolerance to caffeine, reducing its short-term stimulatory effects.
Studies confirm that moderate coffee intake does not contribute to hypertension. However, those who rarely consume coffee may notice an initial, brief spike in blood pressure after drinking caffeinated beverages.
Coffee’s Role in Reducing Inflammation and Disease Risk
Beyond caffeine, coffee is rich in polyphenols, which are antioxidant and anti-inflammatory compounds that contribute to overall health. Research suggests that diets high in polyphenols can help protect against conditions such as type 2 diabetes, high blood pressure, obesity, and metabolic syndrome.
By reducing inflammation, polyphenols support cardiovascular function and enhance the body’s ability to regulate metabolic processes. Since coffee is one of the richest dietary sources of these compounds, daily consumption may provide long-term health benefits.
Recommended Coffee Intake for Health Benefits
The U.S. Food and Drug Administration advises that up to 400 milligrams of caffeine per day—approximately two to three cups of brewed coffee—is considered safe for most adults. The study also found that the health benefits of coffee peak between two and three cups per day. While higher consumption does not necessarily cause harm, it may not offer additional advantages, especially for individuals sensitive to caffeine.
Researchers also caution that added sugars, syrups, and high-calorie creamers can reduce the health benefits of coffee. Experts recommend consuming coffee with minimal additives or opting for healthier alternatives such as plant-based milk or cinnamon.
Key Takeaways from the Study
This latest research highlights that the timing of coffee consumption is as important as the amount consumed. Drinking coffee in the morning is associated with a lower risk of heart disease and longer lifespan, while consuming coffee throughout the day may interfere with sleep, circadian rhythms, and cardiovascular health.
For those looking to maximize coffee’s health benefits, limiting consumption to the morning hours and maintaining a moderate intake of two to three cups per day may be the most effective approach.
