These sleep-related breathing difficulties occur when soft tissues collapse and block the upper airway. In more serious cases, individuals suffer momentary lapses in breathing, followed by micro-awakenings that interrupt the progression of the sleep stages. After a few drinks, these increased adenosine levels send us into a deep sleep.
You reach for a coffee or another stimulant to give you energy for the day. This can lead to insomnia, or having a hard time falling asleep the next night.
Allen RP, Faillace LA, Wagman A. Recovery time for alcoholics after prolonged alcohol intoxication. No single neurotransmitter system is sufficient for ensuring normal sleep. Rather, normal sleep depends on a complex interplay of numerous neurotransmitter systems and sleep factors , many of which are also affected by alcohol.
A summary of nocturnal sleep changes in alcoholic patients as determined across various polysomnographic studies of acute alcohol administration and withdrawal. The studies measured sleep characteristics at baseline, after drinking, and during acute alcohol withdrawal. Note that the size of the bars indicates only the direction, but not the magnitude, of the changes. Both after drinking and during withdrawal, sleep latency increases and total sleep time decreases, compared with the response at baseline. Both the percentage of deep sleep, or slow-wave sleep , and the rapid eye movement sleep latency increase during drinking and return to baseline levels during withdrawal. Although SWS% returns to baseline values during withdrawal, researchers should note that baseline values of SWS% in alcoholics are still lower than values from control subjects.

Sleep apnea is a common but serious sleep disorder where your airway is partially or completely blocked while you sleep. Obstructive sleep apnea can create or worsen other comorbidities of OSA such as high blood pressure, diabetes, and even erectile dysfunction. A sleep disorder is often the main culprit of sleep disruption. Unfortunately, if you have a sleep disorder and drink alcohol at night, you may be unintentionally adding to your sleep problems. Alcohol relaxes the muscles in your throat, which can make it more likely for your upper airway to become obstructed or collapse. This increases how much the soft tissue in your throat vibrates while you breathe, causing the familiar sound of snoring. If you just have one or two drinks, you may not notice any disruptions in your sleep, so you’ll be more likely to think alcohol is helping you sleep.
But it can actually end up robbing you of a good night’s rest — or worse, could cause some challenging sleep problems. Drink alcohol as you’re eating a meal — since you’re likely eating a few hours before bed, this is a good way to keep drinking in check. Wagman AM, Allen RP. Effects of alcohol ingestion and abstinence on slow wave sleep of alcoholics. Gross MM, Hastey JM. The relation between baseline slow wave sleep and the slow wave sleep response to alcohol in alcoholics. Increased REM sleep density at admission predicts relapse by three months in primary alcoholics with a lifetime diagnosis of secondary depression. Several so-called sleep factors also have been implicated in the initiation and maintenance of sleep.
A night of alcohol-induced poor sleep can kickstart a cycle of drinking caffeine in the morning and throughout the day to help you stay alert. A feeling of wanting alcohol again at night to help you fall asleep.
“The take-home message is not to resort to alcohol as a go-to sleep aid. If you’re having trouble sleeping, wean off alcohol, especially if you’re having problems maintaining sleep,” said Gamaldo. When sleep is disrupted a person is more susceptible to depression disorders and a decrease in cognitive abilities. Studies show that normal memory function is dependent on adequate sleep.
Moreover, it can take one hour for your body to process one serving of alcohol. Verywell Health articles are reviewed by board-certified physicians and healthcare professionals.

Sleepwalking and parasomnias —You may experience moving a lot or talking while you’re sleeping. There’s a chance you’ll physically act out your dreams in your sleep, or evensleepwalk. If you have alcohol in your system when you hit the hay, you may not sleep very deeply, or for very long, on and off throughout the night. That’s because as alcohol starts to metabolize, the sedative effect wears off. If you experience consistent snoring and any one of the symptoms listed above, it may be time to talk to someone about your sleep issues. Allow at minimum three hours between your last drink and the time you go to bed. Nighttime hypoxemia is increased in abstaining chronic alcoholic men.

Although some studies documented a return to normal REM% at 3 to 9 months, REM% may remain elevated for 27 months. These inconsistent findings regarding REM sleep may reflect differences in alcoholic subtypes in the different studies. Thus, persistent REM sleep abnormalities were most evident in depressed alcoholics (Gillin et al. 1990a; Moeller et al. 1993) and alcoholics who subsequently relapsed (Gillin et al. 1994; Brower et al. 1998). Having a glass of wine or a nightcap before bed is a common nighttime ritual. In fact, approximately 20% of the U.S. adult population drinks alcohol to help them fall asleep. Alcohol may increase the number of times you stop breathing during the night. Essentially, this means your SA is more severe when you drink alcohol.
Incidents of apnea followed by awakening can occur hundreds of times during the night, significantly reducing sleep time. Chronic alcohol use appears to be linked to an increased risk for sleep apnea, especially among drinkers who snore. Over time, the drink before bedtime works even less effectively. With continued consumption, studies found alcohol’s sleep-inducing effects decrease, while its sleep disturbance effects increase. It’s estimated that between 35% and 70% of people who drink alcohol live with insomnia. It’s a little bit of a chicken and an egg situation — troubles with insomnia can be made worse by alcohol consumption.
The investigators found that patients with poor outcomes had significantly lower levels of baseline SWS% than did patients with good outcomes. Likewise, preliminary data collected by Aldrich and colleagues suggested that relapse was related to low levels of SWS%. However, these findings could not be replicated in a larger sample (Brower et al. 1998). Finally, several other clinical outcome studies detected no relationship between SWS measures and relapse (Clark et al. 1998; Drummond et al. 1988; Gillin et al. 1994). Numerous neurotransmitter systems and other substances are involved in the regulation of sleep and various sleep stages.
You need a specific amount of REM sleep and NREM sleep each night to feel rested in the morning. Alcohol imbalances how long you spend in each sleep stage at night, causing poor sleep quality and short sleep duration. The more you drink at night, the more your sleep quality will likely suffer. However, even a single alcoholic drink or two in the evening can have negative effects on your sleep, especially if they’re consumed too close to bedtime. Your CNS controls most of your bodily functions, including your breathing, your heart, and your brain activity— which includes your sleep. In fact, sleep disorders are common in people with a depressed central nervous system. If you drink a glass of wine before bed, you notice you fall asleep easier.
Finally, proteins produced by the immune system (i.e., cytokines) have known effects on sleep and are altered in alcoholic individuals (Ehlers 2000; Krueger et al. 1999). Another excitatory neurotransmitter whose activity is altered by alcohol and which may contribute to withdrawal symptoms is noradrenaline. Noradrenaline activity is enhanced during alcohol withdrawal (Hawley et al. 1985), which likely contributes to increased arousal alcohol and sleep during the early withdrawal phase. Therefore, HRV measurements enabled the researchers to assess the quality of the participants’ restful state. The scientists examined the participants’ first 3 hours of sleep after drinking alcohol. A new study assesses the effect of alcohol consumption on the restorative quality of sleep. The findings might make you want to change your drinking — and implicitly, your sleeping — habits.
At the same time, alcohol consumption, through its effects on brain chemicals (i.e., neurotoxicity), may lead to sleep disturbance. Sleep disturbance is also a risk factor for developing alcohol-use disorders (i.e., alcohol abuse and alcohol dependence). Treatment of these disorders can lead to abstinence, but sleep disturbances may persist even during recent and sustained abstinence. Sleep disturbances at the time of treatment are risk factors for relapse to drinking. In turn, relapse contributes to alcohol neurotoxicity and persistent sleep disturbances. The question mark represents the untested hypothesis that treatment of sleep disturbances as an adjunct to alcoholism treatment can facilitate abstinence and decrease the risk of relapse.
Unfortunately, only one study (Tan et al. 1985) calculated the proportion of control subjects with an apnea index greater than 5. However, the number of those control subjects (i.e., 12 persons, out of whom none had an apnea index greater than 5) was too small to provide an adequate comparison across the three studies. In addition to psychiatric comorbidity, such as depression, researchers have identified other variables that can influence sleep measures in recently abstinent alcoholic patients. The gold standard for objectively measuring sleep is polysomnography. The term “sleep latency” refers to the time between going to bed and sleep onset. Similarly, the term “REM sleep latency” refers to the time between sleep onset and the onset of the first episode of REM sleep.
