Alcohol Next-Morning HRV Dip
An alcohol next-morning HRV dip is lower heart-rate variability after modest drinking—often visible on wearables before hangover symptoms appear.
An alcohol next-morning HRV dip is the common drop in heart-rate variability on wearables after one to three drinks—even when you do not feel hungover. Sympathetic load stays elevated while the liver clears ethanol and sleep stays shallow.
Compare to your baseline, not a friend's score. Use dips as a moderation signal, not moral judgment.
