The Alcohol Sleep Paradox

Alcohol is a sedative that helps you fall asleep faster. But sedation is not the same as sleep. While unconscious, your brain doesn't cycle through sleep stages properly.

What Alcohol Does to Sleep

🧪 Study finding: Just one drink before bed reduces sleep quality by 9.3%. Three or more drinks reduce it by 39.2%.

The 3-Hour Rule

If you do drink, stop at least 3 hours before bed. This allows your body to metabolize most of the alcohol before sleep begins.

Better Evening Alternatives

Replace the evening drink ritual with: herbal tea (chamomile, valerian), sparkling water with lime, or a relaxing activity like reading or stretching.
