Researchers from a 2020 study concluded that those with AUD need at least 5–9 months of abstaining from drinking in order to normalize their sleep duration and rhythm, so try to be patient with yourself during this time. Circadian rhythms affect how the body responds to alcohol, depending on the timing of alcohol intake. Long-established research shows the body metabolizes alcohol differently at different times of day. Studies have shown the body is more effective at processing alcohol at certain times of the day than others. Long-term heavy drinkers may be predisposed to developing an anxiety disorder.

Drinking alcohol before bed can increase the suppression of REM sleep during the first two cycles. Since alcohol is a sedative, sleep onset is often shorter for drinkers and some fall into deep sleep rather quickly. As the night progresses, this can create an imbalance between slow-wave sleep and REM sleep, resulting in less of the latter and more of the former. This imbalance decreases overall sleep quality, which can result in shorter sleep duration and more sleep disruptions. Alcohol is highly effective at suppressing melatonin, a key facilitator of sleep and regulator of sleep-wake cycles. Research indicates that a moderate dose of alcohol up to an hour before bedtime can reduce melatonin production by nearly 20 percent.

Alcohol has been linked to reduced rapid eye movement (REM) sleep. Alcohol-induced anxiety can last for several hours, or even for an entire day after drinking. Alcohol changes levels of serotonin and other neurotransmitters in the brain, which can worsen anxiety. Alcohol is a sedative and a depressant that affects the central nervous system.

The relationship between sleep apnea and alcohol has been researched fairly extensively. To understand how alcohol impacts sleep, it is important to understand the different stages of the human sleep cycle.

Alcohol interferes with these circadian rhythms regulating the liver, and can contribute to compromised liver function, liver toxicity, and disease. If you’re having trouble falling or staying asleep often, see your healthcare provider. They can rule out any underlying cause for your insomnia and recommend the best treatment for you.

Ask your doctor if moderate alcohol consumption is suitable for you. But even if you thud into dreamland, there’s a good chance that too much alcohol will mean a fitful night of sleep. That’s because alcohol disrupts what’s known as your sleep architecture, the normal phases of deeper and lighter sleep we go through every night.

It’s true, sleep may happen more quickly after consuming a drink or two. Alcohol often does reduce sleep onset latency—the time it takes to fall asleep. Depending on how much alcohol is consumed, however, what seems like falling asleep may be something closer to passing out. And we quickly build a tolerance for the sedative effects of alcohol, which means you may need to drink more to have the same initial sleep-inducing effects.

Obstructive sleep apnea (OSA) occurs due to physical blockages in the back of the throat, while central sleep apnea (CSA) occurs because the brain cannot properly signal the muscles that control breathing. As your body metabolizes the alcohol and the sedative effects wear off, it can interfere with your circadian rhythm, and cause you to wake up frequently or before you’re properly rested. In the first half of the night, when the body is metabolizing alcohol, studies show people spend more time in deep, slow-wave sleep and less time in REM sleep. Sleep architecture is biologically driven and finely calibrated to meet the body’s needs during nightly rest—changes to the natural, typical structure of sleep aren’t generally good for health or well being. REM sleep, which gets shortchanged in the first half of the night under the influence of alcohol, is important for mental restoration, including memory and emotional processing.
