Is your nightcap actually helping your sleep?
A lot of people think alcohol “helps” them sleep, but that couldn’t be further from the truth.
Alcohol is a sedative; it numbs the part of your brain that responds to stimuli and slows your reaction time.
Falling asleep faster does not mean sleeping better.
In fact, even moderate amounts of alcohol can decrease sleep efficiency.
Here’s why it matters:
✴︎ Drinking alcohol within 3 hours of bed…
✴︎ Decreases REM and deep NREM sleep - the stages essential for recovery, cognition, metabolism, and emotional regulation.
✴︎ Increases light sleep, which is far less restorative.
✴︎ Increases nighttime awakenings - micro-awakenings, early-morning waking, tossing and turning, and fragmented sleep.
✴︎ Acts as a diuretic - hello, 2 AM bathroom trip.
✴︎ Spikes next-day anxiety (“hangxiety”).
✴︎ Impairs cognition, decision-making, and emotional stability.
The bottom line: No, your nightcap is not helping your sleep at all.
It’s disrupting the very stages your brain and body need to function at a high level.
While eliminating alcohol completely may not be your goal, try reducing the amount and the frequency, and pay attention to how your sleep changes.
And when you’re looking for something to unwind with, try:
- herbal tea
- sparkling water
- a low-sugar mocktail
You might be surprised at how little you miss the real thing once your sleep starts to improve.
