Alcohol is commonly used as a sleep aid–that is, an agent for initiating sleep. Alcohol consumed in the evening has generally predictable effects on REM sleep, slow wave sleep, and sleep time and continuity, but effects on sleep latency are more variable . Sleep researchers have performed experiments with healthy non-alcoholic subjects using alcohol doses ranging from 0.16 to 1.0 g/kg , yielding breath alcohol concentrations as high as 105 mg percent . REM reduction becomes less pronounced with continued alcohol use, but a REM rebound often appears with alcohol cessation. Slow wave sleep increases after moderate to high bedtime alcohol use, but the effect of lower doses on slow wave sleep are again less certain. Slow wave sleep effects diminish with repeated nights of alcohol consumption . The effects of alcohol on sleep continuity and total sleep are quite variable but appear to be dose related.
People with sleep apnea are also prone to loud, disruptive snoring. Some studies have suggested that alcohol contributes to sleep apnea because it causes the throat muscles to relax, which in turn creates more resistance during breathing. This can exacerbate OSA symptoms and lead to disruptive breathing episodes, as well as heavier snoring. Additionally, consuming just one serving of alcohol before bed can lead to OSA and heavy snoring even for people who have not been diagnosed with sleep apnea. If you are having trouble sleeping, talk to your doctor about how to improve your sleep quality. He or she may be able to rule out underlying sleep disorders like sleep apnea and suggest appropriate sleep aids.
A newer study found that one dose of alcohol had no effect on the circadian rhythm in rodents. However, the researchers proposed that perhaps these effects on the circadian rhythm are only seen after several consecutive days of alcohol consumption. In support of the alcohol-melatonin connection, researchers have noticed that individuals suffering from severe alcohol withdrawal tend to have less pronounced melatonin levels and release.

Science does not know what function REM sleep performs for the body, but it seems to be required for restoration. Some studies have found that when laboratory rats are deprived of REM sleep it can result in death within a few weeks.

The liver acts as a filtering system for the body, helping metabolize food and chemicals , and pulling toxins from the bloodstream. Like nearly all of the body’s organs, the liver functions according to circadian rhythms. Alcohol interferes with these circadian rhythms regulating the liver, and can contribute to compromised liver function, liver toxicity, and disease. Miller M. B., Van Reen E., Barker D. H., Roane B.

When you stop drinking alcohol, not only does your mood improve and your skin clear up, but your sleep quality may also get better. Although many people rely on a glass of wine to relax and fall asleep, even just one drink greatly diminishes the quality of that sleep, says neuroscientist Kristen Willeumier, PhD. The daytime caffeine makes it hard for you to sleep, so you drink alcohol in the evening to help you fall asleep, and once again have a poor night’s sleep.
Armeen Poor, MD, is a board-certified pulmonologist and intensivist. He specializes in pulmonary health, critical care, and sleep medicine. With higher doses, especially over long-term consumption, alcohol may have even worse effects on sleep.8 Higher doses of alcohol have been shown to disrupt sleep, particularly during the second half of the night. When you are getting restful sleep, it’s easy to take sleep for granted. However, if you’ve ever struggled with insomnia, you may have a deeper appreciation for how vital sleep is to your overall health and wellbeing.
This vicious cycle of insomnia, caffeine, and alcohol can make it even harder to get the sleep your body needs. The sleep of individuals with depressive and/or anxiety disorders resembles the sleep of persons with alcoholism . Similar REM sleep changes occur during withdrawal in alcoholics with and without secondary depression . Polysomnography is not helpful in differentiating among these disorders or their treatment, and thus should not be considered a primary diagnostic instrument for patients with psychiatric disorders and sleep complaints. Overall, an accurate clinical history is a better indicator of alcohol-related insomnia.
- People who abuse alcohol long-term don’t seem to display the deep recovery sleep that most people show after sleep deprivation, suggesting that the homeostatic drive is no longer functioning as it should.
- Sleep apnea can really take a toll on your physical and mental health.
- Some studies have suggested that alcohol contributes to sleep apnea because it causes the throat muscles to relax, which in turn creates more resistance during breathing.
- The most common type of sleep apnea is obstructive sleep apnea , and it occurs when the tissues in the mouth and throat relax and block the airway during sleep.
Research indicates that a moderate dose of alcohol up to an hour before bedtime can reduce melatonin production by nearly 20 percent. Alcohol has a direct effect on circadian rhythms, diminishing the ability of the master biological clock to respond to the light cues that keep it in sync. Those effects of alcohol on the biological clock appear to persist even without additional drinking, according to research. However, persons who consume alcohol in excessive amounts suffer from poor sleep quality and patients with alcohol use disorders commonly report insomnia.

Without the right level of this hormone, your kidneys store less water and put more into your bladder for urination.

Sleep apnea is a disorder where the muscles in your throat relax during sleep, blocking your airways and momentarily stopping your breathing. Your brain realizes that oxygen levels are dropping, and briefly wakes you up to tighten the muscles and restart the breath. People don’t always realize this is happening, and in the morning, you might not remember waking up during the night. Our bodies are regulated by a 24-hour master biological clock that governs our circadian rhythm, which alcohol tampers with.
The circadian rhythm regulates our bodies’ processes — metabolism, cardiovascular, brain power,depression and moods, sleep, etc., so when we drink alcohol, we’re tampering with our bodies’ systems. Therefore, we conducted this study to examine the effects of alcohol consumption on sleep quality and to provide recommendations for improving sleep quality. Among patients with diagnosed alcohol dependence, the rate of sleep disturbance is higher than the general population.

People who consume alcohol before bed don’t wake up as often during the first few hours of sleep. “Sleep is essential for the preservation of brain energy, facilitation of learning and memory, support of cognitive capacity, emotional regulation, and clearance of toxic waste,” says Dr. Willeumier. “Alcohol consumption disrupts restorative sleep and can result in impaired immune, cardiovascular, and cognitive health. Furthermore, insomnia increases your risk for mood disorders and substance abuse.”
“It’s hard to overstate the importance of sleep, in terms of both quality and quantity,” adds Prof. Myllymäki. That extra glass of wine could make your sleep less restful and regenerative. Moreover, it can take one hour for your body to process one serving of alcohol. Verywell Health’s content is for informational and educational purposes only.

So, you’ll likely need to get up in the middle of the night to use the bathroom. “That sense of a hangover is actually from intense dehydration from your body getting rid of all that alcohol,” said Gamaldo. Alcohol can lead to excessive relaxation of the muscles in the head, neck, and throat, which may interfere with normal breathing during sleep.
