Alcohol and Sleep Efficiency Score

Alcohol and sleep efficiency score ties evening drinks to lower percent of time in bed asleep—often from mid-night awakenings after ethanol clears.

Alcohol and sleep efficiency score links evening drinking to the percent of time in bed actually asleep—wake-after-sleep-onset rises when ethanol fragments the second half of the night. Efficiency below roughly eighty-five percent on multiple nights after social weeks signals a moderation tweak, not more time in bed alone.

Pair efficiency with latency and REM trends.

Common questions

  • Should you extend bedtime if efficiency is low?

    Fix fragmentation causes first—alcohol timing, heat, stress—not only more hours in bed, which can worsen shallow sleep.
