Summary
Multi-domain evidence is consistent: alcohol shortens REM, elevates cortisol/HR, shrinks hippocampal volume in imaging cohorts, raises inflammatory markers, and accelerates multiple epigenetic-clock measures. 2023 Lancet re-analysis and WHO 2023 statement shifted the field toward 'no safe level.' Effect magnitudes are dose-dependent; heavy/daily use drives most harm.
