Summary

A Tulane University study found that drinking coffee only in the morning is linked to a 16% lower risk of death from all causes and a 31% lower risk of heart disease compared to non-coffee drinkers.

Researchers analyzed data from over 40,000 U.S. adults and suggested morning coffee between 4:00 a.m. and noon aligns with natural sleep-wake cycles, potentially reducing inflammation.

Afternoon and evening coffee showed no benefits, and the study found no link between coffee and reduced cancer mortality.

Experts stress further research is needed before making lifestyle changes.

    The important finding is

    After adjustment for caffeinated and decaffeinated coffee intake amounts, sleep hours, and other confounders, the morning-type pattern, rather than the all-day-type pattern, was significantly associated with lower risks of all-cause (hazard ratio: .84; 95% confidential interval: .74–.95) and cardiovascular disease-specific (hazard ratio: .69; 95% confidential interval: .55–.87) mortality as compared with non-coffee drinking.

    So people who drank coffee ONLY in the morning had significant advantages compared to the non-coffee drinking population. All-day drinkers did not have significant advantages.
