- A 2025 study suggested that the time of day you drink coffee may affect your mortality risk, especially from cardiovascular disease.
- A recent study found that moderate consumption of caffeinated coffee (2 to 3 cups) or tea (1 to 2 cups) may reduce dementia risk and slow cognitive decline.
- Other research shows that moderate coffee consumption (3 to 5 cups) may help lower the risk of major diseases, such as cardiovascular disease, diabetes, stroke, and certain cancers.
Coffee is one of the most widely consumed beverages globally. Over 60% of people in the United States consume coffee daily.
A 2025 study analyzed patterns of coffee drinking and whether the time of day it is consumed affects mortality outcomes. The study found that people who consumed coffee primarily in the morning, rather than throughout the day, had a lower mortality risk than non-coffee drinkers.
A study published on February 9 in JAMA investigated the effects of consuming caffeinated coffee or tea on dementia risk, cognitive decline, and cognitive function preservation.
Other research has also shown that coffee may have various other health benefits. However, the addition of cream and sugar may reduce these benefits.
Heart health benefits of morning coffee
The 2025 study showed that people who drink coffee in the morning, rather than throughout the day or not all, may have a reduced risk of death from cardiovascular disease, as well as a lower overall mortality risk.
“Drinking coffee in the morning shows a better beneficial relation than all-day drinking with cardiovascular and all-cause mortality,” Lu Qi, MD, PhD, lead author of the study, HCA Regents Distinguished Chair and Professor at the Celia Scott Weatherhead School of Public Health and Tropical Medicine at Tulane University, told Healthline in an earlier interview.
The study involved more than 40,000 adults from the National Health and Nutrition Examination Survey (NHANES) and 1,463 adults from the Women’s and Men’s Lifestyle Validation Study.
Both of these surveys included lifestyle and health data from a cross-section of adults in the United States. This included questions about coffee and caffeine consumption.
Around 48% of the participants were non-coffee drinkers. The remaining participants were divided into two groups, based on their coffee consumption patterns.
About one-third of the participants were “morning-type coffee drinkers.” This means they consumed almost all coffee before noon, rarely consuming it in the afternoon or evening.
Around 16% of participants were in the second, “all-day-type” coffee drinkers. This means they consumed coffee throughout the day and into the evening.
Only the morning coffee group demonstrated significant risk reduction in all-cause mortality and cardiovascular disease-related death.
“At most, one can say if you are a coffee drinker, consider limiting it to AM hours, but this study is not designed or powered to talk about causality,” said Abha Khandelwal, MD, a professor of cardiovascular medicine at Stanford Medicine who wasn’t affiliated with the study.
