Long-Term Coffee Drinking Doesn’t Raise Early Death Risk

For years, coffee drinkers have faced conflicting advice: some studies warn that regular coffee consumption might raise the risk of early death, while others praise its benefits. If you’ve been worried that your daily cup—or three—could be silently harming your health, a major new study offers reassuring data.

The short answer? Drinking coffee daily—at moderate levels—does not increase your risk of dying early. In a 19-year study tracking more than 125,000 health professionals, researchers found no link between habitual coffee intake and higher mortality rates among those without prior cardiovascular or cancer conditions.

What the Spanish Study Actually Found

Published in the Annals of Internal Medicine, the research led by scientists at Autonomous University of Madrid analyzed data from 84,000 middle-aged women and 41,000 middle-aged men. All participants were employed in health system jobs, had no history of cardiovascular disease or cancer, and reported regular coffee consumption. The study spanned from 1986 to 2004, making it one of the longest-running investigations into coffee’s long-term health effects on a professional population.

How Researchers Tracked Coffee and Mortality

Participants were monitored over nearly two decades, with researchers recording their coffee intake habits and tracking mortality outcomes. The key finding: individuals who maintained a typical, moderate coffee consumption pattern did not experience an increased risk of death compared to non-drinkers or low-level consumers. The study focused specifically on individuals without pre-existing cardiovascular or cancer conditions, isolating coffee’s effects in a relatively healthy population.

Why Past Studies Raised Concerns

Coffee contains caffeine and other bioactive compounds that can stimulate the nervous system and affect heart rate and blood pressure. Because of these physiological effects, scientists have long debated whether regular coffee consumption might contribute to cardiovascular strain, anxiety, or other health risks that could potentially shorten lifespan. These concerns have fueled decades of conflicting studies on whether coffee is helpful, harmful, or simply neutral.
