Heavy Coffee Drinkers With Severe Hypertension Face Higher Death Risk, Study Finds

A new Japanese study has highlighted a potential risk for heavy coffee drinkers with severe hypertension. Researchers found that those consuming large amounts of coffee near me faced double the risk of dying from cardiovascular disease. The findings add to ongoing discussions about how caffeine affects heart health.

Coffee's relationship with blood pressure has been debated for decades. Earlier research suggested caffeine caused long-term hypertension, but recent studies show only a temporary spike. A typical cup can raise systolic pressure by 3–15 mmHg and diastolic by 4–13 mmHg, lasting one to three hours. Meta-analyses in journals like the American Journal of Clinical Nutrition and Nutrients now confirm no lasting risk for people with high blood pressure.

Guidelines from the European Society of Hypertension and the American Heart Association have adjusted accordingly. Instead of strict limits, they recommend testing individual tolerance, allowing moderate intake of three to four cups daily. Coffee also contains beneficial compounds like melanoidins and quinic acid, which may support blood vessel function and fluid balance.

Genetics play a role in how much coffee a person drinks. Variations in brain reward systems and caffeine metabolism influence consumption habits. Despite this, research shows no direct link between coffee and developing hypertension. Global coffee intake has steadily risen, averaging nearly two kilos per person annually.

The study underscores the need for awareness, particularly among those with severe hypertension. Experts advise knowing personal health risks, monitoring caffeine's short-term effects, and considering moderation. For most, coffee remains safe in reasonable amounts, but individual responses can vary.
