Why might I be unable to sleep after drinking alcohol and how can I improve my sleep?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Alcohol can disrupt sleep by fragmenting sleep cycles and triggering restless leg movements at night. While a drink may feel relaxing, alcohol reduces REM sleep, increases nighttime awakenings, and can worsen conditions like restless legs syndrome. To improve sleep quality, avoid alcohol for at least 3–4 hours before bedtime.

If poor sleep, restless legs, or nighttime symptoms are affecting your daily life, it's worth understanding the root cause. Sleep disturbances can stem from many factors beyond alcohol, including underlying health conditions that benefit from early attention. Take a free, instant, online symptom check to get personalized insight into your symptoms and clear guidance on next steps—so you can stop guessing and start sleeping better.

Explanation

Drinking alcohol can affect your sleep in several ways. It might seem like alcohol helps you fall asleep faster, but it can actually cause sleep problems during the night. One study found that alcohol consumption is linked to sleep issues, such as waking up often or feeling tired in the morning.

Another study showed that alcohol can cause your legs to move a lot while you sleep, which can wake you up. This is called periodic limb movements. This makes it hard to stay asleep and get good rest.

To help improve your sleep:

Avoid alcohol before bed: Try not to drink alcohol close to bedtime.
Create a bedtime routine: Go to bed at the same time every night and do calming activities like reading.
Make your bedroom comfortable: Keep your room dark, quiet, and cool.

If you keep having trouble sleeping or experiencing other concerning symptoms, you can check what might be causing them with a free symptom checker and talk to a healthcare provider for personalized guidance.
