There is a lack of evidence that alcohol consumption is a trigger for sleepwalking (Pressman et al., 2007), although it has been linked epidemiologically to night terrors, which is another parasomnia (Ohayon et al., 1999). Drinking to excess will typically have a more negative impact on sleep than light or moderate alcohol consumption. Research has alcohol insomnia shown that those who drink large amounts of alcohol before bed are more likely to take less time to fall asleep, but are also more likely to experience sleep disruptions and decreases in sleep quality. However, since the effects of alcohol are different from person to person, even small amounts of alcohol can reduce sleep quality for some people.
- Data are presented from a baseline night, three drinking nights and the mean of
two recovery nights.
- Sustained nightly drinking can establish worrying patterns that can persist even after people have stopped drinking, she and other experts say.
- The right
panel (KC-) show the result of averaging responses not including K-complexes.
- Latencies of N550 and P900 did not differ as a function of diagnosis
- When alcohol depresses the nervous system, falling asleep is easier and happens faster.
In a larger study, Colrain et al. (2009)
studied 42 abstinent long-term alcoholics (27 men) and 42 controls (19 men). As in the
previous study (Nicholas et al. 2002), alcoholics
were significantly less likely to produce K-complexes than controls. P2 amplitude was,
however, smaller in alcoholics than controls with the difference being largest at Cz,
where the component was maximal, but smaller at other sites (see Figure 5). There were no sex
differences or interactions between diagnosis and sex for K-complex incidence, P2
amplitude or P2 latency.
Disrupted sleep cycle
When someone with insomnia uses alcohol to treat symptoms of insomnia there’s an increased risk of an alcohol addiction developing. Individuals who use alcohol to treat insomnia can also experience reduced sleep quality. More water released by the kidneys increases the rate of urination, which can cause people to wake up throughout the night to pee. Waking up multiple times per night to use the bathroom can contribute to insomnia and reduce sleep quality. Alcohol addiction can lead to symptoms of withdrawal, which can make it harder to fall asleep when alcohol is not consumed. When alcohol has been abused for many decades, symptoms of withdrawal can begin within a few hours, which can harm sleep.
By contrast, primary insomniacs have greater beta
power during NREM sleep than normal sleepers, thought to reflect higher levels of cortical
arousal (Riemann et al. 2010). Differences in slow frequency between alcoholics and
controls were also more marked over the frontal scalp with alcoholics showing lower delta
EEG power (Figure 3). This topographic pattern is
consistent with the known frontal susceptibility to alcoholism-related alterations in
brain https://ecosoberhouse.com/ structure and function (Zahr et al. 2013;
Oscar-Berman et al. 2013). There is also evidence of increased REM sleep pressure (Gillin et al. 1990; Drummond et al. 1998;
Thompson et al. 1995; Gann et al. 2001; Feige et al.
2007; Colrain, Turlington, and Baker 2009b). It is reasonable to expect increased REM pressure in actively drinking or recently
detoxified alcoholics, given that REM sleep is suppressed with high doses of alcohol (Aldrich 1998).

People may sleep through the night but enter REM sleep less frequently, which is the sleep stage where damage to the body is repaired. When alcohol is abused over long periods the negative effects of bad sleep quality become more prevalent. In some cases, insomnia can also develop as a symptom of alcohol dependency.
- The amount of alcohol someone consumes depends on other factors that can be based on social life, genetics, and even stress.
- Yules, Freedman, and Chandler (1966)
studied three young non-alcohol dependent, men over 5 nights of drinking, with 1g/Kg
ethanol administered 15 minutes before bedtime.
- Drinking alcohol can disrupt the rapid eye movement (REM) phase of sleep, an important, restorative stage of deep sleep during which dreaming occurs.
- More water released by the kidneys increases the rate of urination, which can cause people to wake up throughout the night to pee.
- The good news is that these sleep disruptions are temporary, and any insomnia you experience will likely resolve as you persevere through recovery.
- Habits like binge drinking increase the risk of alcoholism and people who abuse alcohol at a young age are more likely to become lifelong alcoholics.
Drinking alcohol can affect the quality and length of your sleep, leading to sleep disorders — such as insomnia and sleep apnea — in some. Alcohol withdrawal leads to reductions in deep sleep and abnormalities in REM sleep. REM sleep is characterized by increased brain activity, relaxation of the body, rapid eye movements, and increased dreaming. Individuals living with AUD experience much poorer sleep quality than those who consume moderate amounts of alcohol. Studies have shown that short-term alcohol use can shorten the time it takes to fall asleep.
