Jakarta – A new large-scale study is challenging conventional wisdom about coffee consumption, suggesting when you drink your coffee may be just as important as how much. Researchers analyzing data from over 40,000 U.S. adults have found a correlation between the timing of coffee intake and health outcomes, particularly regarding mortality risk and cardiovascular health. The findings indicate that enjoying coffee in the morning may offer distinct advantages over spreading consumption throughout the day, prompting a reevaluation of long-held beliefs about this popular beverage.
A large-scale study is shedding new light on the simple habit of drinking coffee and its surprisingly significant impact on health. The timing of coffee consumption, as well as the amount, may play a crucial role in realizing its benefits.
Researchers analyzed data from tens of thousands of adults in the United States and found distinct differences in health outcomes between those who drank coffee in the morning versus those who consumed it throughout the day.
The study explored participants’ coffee-drinking patterns, revealing a notable correlation between when coffee was enjoyed and potential health advantages. This research opens a new discussion about how the body’s natural rhythms and caffeine intake timing can influence mortality risk and cardiovascular health.

Recent research suggests that the time of day you enjoy your coffee can impact its health benefits. The study, involving over 40,000 adults in the United States, identified two distinct coffee-drinking patterns.
Coffee consumption was categorized into three periods: morning (4:00 AM – 11:59 AM), afternoon (12:00 PM – 4:59 PM), and evening (5:00 PM – 3:59 AM).
The first group consisted of those who drank coffee before noon, and the second group consumed coffee throughout the day. Results showed that morning coffee drinkers had a 16% lower risk of death compared to those who did not drink coffee.
Additionally, those who regularly drank coffee in the morning had a 31% lower risk of dying from heart disease. These findings suggest that consuming coffee in the morning may have a greater health impact than drinking it throughout the day.

Unlike morning coffee drinkers, those who consumed coffee throughout the day did not show a reduction in the risk of death or heart disease.
The research also highlighted that higher coffee consumption was significantly linked to a lower risk of death, but only within the group that drank it in the morning. Researchers speculate that drinking coffee into the afternoon or evening may disrupt the body’s circadian rhythm and decrease the production of hormones like melatonin, which regulates sleep.
Sleep disturbances can trigger changes in blood pressure and inflammation, impacting cardiovascular health.

Dr. Lu Qi of Tulane University, the lead author of the study, explained that this research is the first to investigate the relationship between the timing of coffee consumption and health risks. He noted that coffee has long been known not to increase the risk of heart disease and may even lower the risk of several chronic diseases.
However, the timing of coffee consumption has not been studied in depth until now. Dr. Qi added that consuming coffee in the afternoon or evening could potentially disrupt biological rhythms and affect hormone levels, negatively impacting cardiovascular risk factors.
He emphasized the need for further studies to test the impact of changing the timing of coffee consumption on health.
4. Experts Recommend Morning Coffee for Greater Benefits

Professor Thomas Lüscher of Royal Brompton and Harefield Hospitals in London, England, stated that many all-day coffee drinkers experience sleep disturbances. He believes that the current scientific evidence strongly suggests that drinking coffee in the morning is better for health.
He noted that coffee consumption remains safe, but timing is important. Similar findings were observed in both caffeinated and decaffeinated coffee drinkers. Researchers observed that morning coffee drinkers tended to consume less coffee overall than those who drank it throughout the day.
However, this pattern was associated with greater health benefits. These findings suggest that future recommendations regarding coffee consumption may need to consider the timing of intake, not just the amount of coffee or caffeine.
