How Alcohol Affects Sleep—and What to Record

How Alcohol Affects Sleep—and What to Record

Feeling sleepy after drinking does not mean the night will be restful. NHLBI explains that alcohol can make it easier to fall asleep while making sleep lighter and nighttime waking more likely. If sleep is a concern, include drinking in the conversation with your healthcare professional.

Look beyond the time you fell asleep

Notice awakenings, when you got up, how you felt during the day and whether your schedule changed. Alcohol is one possible influence among others, including stress, medicines, caffeine and the sleep environment. Your experience cannot establish which factor caused a particular night.

We removed precise “sleep quality” percentages and a fixed recovery deadline from the previous article because those statements exceeded the evidence we could verify. There is no universal number of alcohol-free nights after which this guide can promise normal sleep.

Keep a useful sleep record

NHLBI suggests a sleep diary when preparing for an assessment. Note sleep and waking times, naps, daytime sleepiness, caffeine or alcohol, and exercise. Record estimates as estimates, including nights you did not drink. A short note is more useful than filling missing days with guesses.

Use observations to ask for help

If sleep problems affect daily life or persist, discuss them with a health professional. Ask about medicines and other possible causes rather than using alcohol as a sleep remedy or adjusting prescriptions yourself. Our appointment guide can help prepare questions.

Suddenly stopping after prolonged heavy drinking can cause dangerous withdrawal. Seek medical advice about stopping if this may apply to you. A diary does not assess withdrawal risk or calculate a personal safe drinking threshold.
