Health effects

Liver

Regular alcohol consumption stresses the liver. From ~30g/day (women) or ~60g/day (men) the risk of fatty liver and cirrhosis rises significantly.

Cancer risk

Alcohol is a class 1 carcinogen (IARC). No level of consumption is entirely risk-free. Risk increases linearly with the amount consumed.

Cardiovascular

Regular consumption above guideline limits raises blood pressure, increases arrhythmia risk, and raises stroke risk.

Sleep & recovery

Alcohol impairs sleep quality, suppresses REM sleep, and increases daytime fatigue even after moderate consumption.
