Cardiologists urge zero tolerance for alcohol due to health risks

Medical experts are calling for a zero-tolerance approach to alcohol consumption due to its significant impact on cardiovascular and long-term health. Cardiologists, including Professor Volker Schächinger from Klinikum Fulda, highlight that even small amounts of alcohol, such as red wine, can trigger atrial fibrillation and increase cancer risks.

Beyond heart rhythm issues, alcohol consumption is linked to DNA damage via the byproduct acetaldehyde, which is carcinogenic. It also causes oxidative stress, disrupts metabolism leading to fatty liver disease, and negatively affects brain and nerve cells. Furthermore, alcohol severely impairs sleep architecture, specifically REM and deep sleep, and can keep heart rates elevated throughout the night, preventing adequate recovery.

To mitigate cardiovascular risks, experts recommend at least 150 minutes of exercise per week. While official guidelines from the Deutsche Hauptstelle für Suchtfragen suggest lower-risk limits—such as 12 grams of alcohol per day for women and 24 grams for men—medical professionals are increasingly emphasizing that any amount can pose health risks.
