How Does Alcohol Affect Sleep? It’s Worse Than You Think
It can make it harder to get a good night’s sleep and can make your SA worse. In fact, heavy drinking is a common risk factor for OSA, and can even cause apnea events in those who don’t have SA. Making this nightcap an ongoing habit will simply introduce more long-term problems.
- Unfortunately, if you have a sleep disorder and drink alcohol at night, you may be unintentionally adding to your sleep problems.
- The homeostatic drive is responsible for keeping our body balanced, and it’s one of the major mechanisms that regulates the sleep-wake cycle.

- A history of using alcohol to promote sleep, however, does not appear to be a significant predictor of relapse (Brower et al. 2001).
- Similarly, the GABAA agonist diazepam increased polysomnographically measured total sleep time in alcoholic humans (Aubin et al. 1994).
- Furthermore, low alcohol doses, which can be stimulating in humans , have been shown to raise nor-epinephrine levels in the cortex of rats (Rossetti et al. 1992).
Between 10 and 15 percent of cases of chronic insomnia are related to substance abuse, including alcohol abuse. When you’re wound up at the end of a long, stressful day, a nightcap may sound like the perfect way to relax before bed. But while a little alcohol may make you feel sleepy, it can set you up for a restless night. Can you unwind with a late-night drink without winding up fatigued in the morning? Alcohol , found in alcoholic beverages, can exacerbate sleep disturbances. During abstinence, sleep disruption is one of the greatest predictors of relapse.
Alcohols Effects On Sleep In Alcoholics
However, even moderate amounts of alcohol about an hour before bedtime can lower melatonin levels by about 20%. If you have SA, it’s important to know the risks of drinking alcohol with this serious sleep disorder. Is a serious sleep disorder that can lead you to an early grave. If you’ve been diagnosed with this condition, it’s important to work with our providers to help improve your health and manage your condition. One thing that many people ask is whether they can drink alcohol if they’ve been diagnosed with obstructive sleep apnea . This is a question only you and your doctor can answer, but it’s important to know how alcohol can affect you if you have SA.
The circadian rhythm is responsible for keeping the body anchored to a 24-hour cycle. As part of this 24-hour cycle, the body releases a hormone called melatonin to prepare us for sleep in the evening.
Emerging data demonstrate that insomnia may co-exist with SSD and circadian abnormalities. Future studies should unravel these tentative associations in individuals who misuse alcohol.
- However, alcohol affects everyone differently, and for some people even one drink can negatively affect sleep quality.

- Armed with this real knowledge, you may find that you start to prioritize a healthy night’s sleep over imbibing.
- Chronic alcoholism may cause either slowly reversible or irreversible damage to brain systems that regulate sleep.
- Similarly, objective sleep measures, such as low levels of total sleep time (Clark et al. 1998) and sleep efficiency (Drummond et al. 1998) have been found to predict relapse.
Similarly, the GABAA agonist diazepam increased polysomnographically measured total sleep time in alcoholic humans (Aubin et al. 1994). “The Sleep Doctor” Michael Breus, M.D., recommends only 2-3 alcoholic drinks per week, and not before bedtime. One cocktail after work, a beer in the afternoon, or a glass of wine with dinner will metabolize enough ahead of time not to interrupt, or to minimally interrupt, your sleep. For more recommendations on alcohol consumption, symptoms, and signs of alcoholism, visit ouralcohol addiction resource. We’ll summarize some of those major research milestones in this article, as well as debunk myths about alcohol as an antidote for sleep disorders. In the Kailuan Study, the majority of the sleep data was collected in 2012 via questionnaires administered verbally by trained interviewers . The primary outcome of the current study was overall sleep quality, based on four sleep parameters including insomnia, daytime sleepiness, sleep duration and snoring, as detailed previously.
Why Alcohol Disrupts Your Sleep
Someone might have mild SA on a normal night, but moderate or even severe SA when they drink based on the number of apnea events they have. Restful sleep requires our brains to cycle every ~90 minutes through the various phases of sleep. Alcohol will generally reduce the time it takes to fall asleep and it will increase the amount of deep sleep you get during the first half of the night. However, as your blood alcohol level drops, your sleep becomes less restful for the remainder of the evening and your REM sleep is markedly diminished. The effects of alcohol on the brain are complex and have two distinct phases.
A history of using alcohol to promote sleep, however, does not appear to be a significant predictor of relapse (Brower et al. 2001). Several animal studies addressed the possibility that sleep disturbances in early development could lead to heavy alcohol consumption later in life (e.g., Hilakivi et al. 1987). In these studies, newborn rats were treated with various antidepressants, resulting in reduced levels of REM sleep compared with untreated rats. As adults, the treated rats exhibited decreased levels of certain brain chemicals implicated in sleep (i.e., monoamine neurotransmitters) and increased alcohol consumption compared with the untreated rats.
3In that study, participants drank 8.6 ounces of pure alcohol for 5 days followed by 11.4 ounces of pure alcohol for 5 days. One standard drink (i.e., 12 ounces of beer, 5 ounces of wine, or 1.5 ounces of 80 proof distilled spirits) contains approximately 0.5 ounce of pure alcohol. 2For these experiments, alcoholics undergoing inpatient treatment typically were given alcohol for 1 or more days before withdrawal was induced by withholding alcohol. Such an experimental alcohol and sleep design raises ethical issues by current standards of human research and is generally no longer being used. Smith JW, Johnson LC, Burdick JA. Sleep, psychological and clinical changes during alcohol withdrawal in NAD-treated alcoholics. Several studies assessing abnormalities in SWS% during prolonged sobriety indicated that SWS% remained suppressed for 3 to 14 months (Drummond et al. 1998; Imatoh et al. 1986; Ishibashi et al. 1987; Williams and Rundell 1981).

Development of neurochemical and behavioral sensitivity to ethanol in long-sleep and short-sleep mice. Many polysomnographic studies of sustained abstinence are based on relatively small sample sizes .
Alcohol Can Amplify The Effects Of Sleeping Disorders
The term “sleep efficiency” refers to the proportion of time in bed that is spent sleeping. Other variables used to characterize sleep are the percentage of total sleep time spent in REM sleep (i.e., REM%) and in SWS (i.e., SWS%), respectively. But that can start a dangerous cycle of more fragmented sleep, followed by heavier drinking. Sustained nightly drinking can establish worrying patterns that can persist even after people have stopped drinking, she and other experts say. A recent study reported by Medical News Today, for example, suggested that just one drink can shorten our lifespan. The jury’s still out on whether drinking in moderation is good for you, but some studies have suggested that even light drinkers are at risk of cancer due to their alcohol intake. Alcohol can affect REM sleep and your breathing, both of which can contribute to daytime fatigue.
Three studies to date compared recently abstinent alcoholic patients and nonalcoholic control subjects with respect to PLMs. In one study, PLMs were significantly increased in 20 alcoholic men who had been abstinent for 2 to 36 months (Schiavi et al. 1995). In another study, PLMs were significantly higher in 139 alcoholic subjects who had been abstinent for a mean of 1 month than in 87 control subjects . Conversely, Le Bon and colleagues found an absence of PLMs both in alcoholic subjects who had been abstinent for 3 to 6 weeks and in nonalcoholic subjects. To help assess how alcohol may be affecting your sleep, experts recommend an alcohol-free reset period, or what Dr. Martin called “an alcohol holiday,” lasting at least two weeks.
Sleep In Alcoholics During Experimental Drinking And Acute Withdrawal
The ultimate result is often a refocus on high-quality sleep over almost everything else. And to maximize great sleep, planning for dry days throughout the week becomes a top priority.
In fact, 20% of Americans currently use alcohol as their preferred sleep aid. Scientific evidence points to the fact that alcohol has complex effects on our sleep and in aggregate is detrimental to our health. Cutting back on alcohol is one of the easiest paths to a better night’s sleep.
Therefore, the neurobiological mechanisms that both influence sleep and are affected by alcohol provide a starting point for exploring the reciprocal relationships between alcoholism and sleep . Few studies specified the methodology for determining and verifying abstinence. Thus, some persistent sleep problems could reflect unrecognized drinking. Williams and Rundell noted that REM% normalized by 9 months, whereas REM sleep latency was persistently shortened at 9 months of abstinence. REM sleep generally is suppressed during drinking and either rebounds (with respect to REM%) or returns to baseline levels during withdrawal.
Purple arrows indicate processes that favor unhealthy patterns of drinking, blue arrows indicate processes that favor sleep disturbance, and yellow arrows represent treatment processes that may favor abstinence. Measures of sleep continuity (i.e., sleep latency and total sleep time) are disrupted on both drinking and withdrawal nights in alcoholic patients.
Drinking at night can also cause breathing difficulties such as sleep apnea. At the beginning of the night you may spend more time in deep sleep. But this will cause an imbalance in the sleep cycles in the second half of the night.

Two longitudinal studies that followed alcoholics over several years found that SWS% normalized by 21 to 27 months (Williams and Rundell 1981; Drummond et al. 1998). These results are consistent with the findings of two cross-sectional studies, which reported normal SWS% between 1 and 4 years (Adamson and Burdick 1973; Wagman and Allen 1975). Drummond and colleagues found that REM% remained increased, and REM sleep latency remained decreased after 27 months of abstinence. But this is one shortcut you may want to avoid because while you may fall asleep quickly, the quality of your sleep suffers under the influence.
During both drinking periods and withdrawal, alcoholics commonly experience problems falling asleep and decreased total sleep time. Even alcoholics who have been abstinent for short periods of time (i.e., several weeks) or extended periods of time (i.e., several years) may experience persistent sleep abnormalities. Researchers also found that alcoholics are more likely to suffer from certain sleep disorders, such as sleep apnea. Conversely, sleep problems may predispose some people to developing alcohol problems.
Gross MM, Goodenough DR, Hastey J, Lewis E. Experimental study of sleep in chronic alcoholics before, during and after four days of heavy drinking with a nondrinking comparison. In addition to difficulty falling asleep, broader measures of subjectively reported insomnia also have been correlated with relapse (Brower et al. 2001; Foster and Peters 1999; Skoloda et al. 1979). Similarly, objective sleep measures, such as low levels of total sleep time (Clark et al. 1998) and sleep efficiency (Drummond et al. 1998) have been found to predict relapse.
What You Can Do If Your Sleep Is Impacted
Cerebral atrophy and slow wave sleep of abstinent chronic alcoholics. Acute alcohol administration affects all of the neurotransmitter systems mentioned https://ecosoberhouse.com/ in the previous section . For example, alcohol can enhance GABA activity, which is inhibitory, and can inhibit glutamate activity, which is stimulatory.
