The time of day you drink a cup of coffee may lower the risk of an early death, new research suggests. The study found that people who drank coffee in the morning had a lower risk of dying from cardiovascular disease and had a lower mortality risk than all-day coffee consumers - but the research could not prove whether coffee was the sole cause.

Americans who drank coffee in the morning had a lower overall mortality compared with those who drank coffee later in the day.

A first-of-its-kind study found that morning coffee drinkers have a lower risk of all-cause mortality and cardiovascular disease-related death compared to those who drink coffee throughout the day or not at all.
