Published March 5, 2025 · 8 min read · Updated April 2026
Reviewed for accuracy by licensed clinical professionals.
Recent large-scale studies challenge the belief that moderate drinking protects the heart. WHO and leading cardiology organizations no longer recommend drinking for heart health.
How alcohol damages the heart
Chronic heavy drinking causes cardiomyopathy, arrhythmias, hypertension, and stroke risk. Even moderate drinking elevates blood pressure.
Binge drinking
Particularly dangerous, producing acute blood pressure spikes, arrhythmias, and sudden cardiac death risk.
Bottom line
No level of alcohol is recommended for cardiovascular health. Any potential benefits are outweighed by cancer, liver, and addiction risks.
