Avoid Alcohol Within 4-8 Hours of Bed

Skip alcohol in the evening, especially in the 4–8 hours before sleep, and ideally avoid using it as a nightcap or sleep aid. Alcohol may make you feel drowsy, but it fragments sleep and suppresses REM and slow-wave sleep, leading to poorer sleep architecture and lower-quality rest.

“And alcohol, before we go to sleep, will do that. Until we've metabolized alcohol and put it out of our bodies, it will affect our sleep badly.”
