Alcohol and Sleep

The alcoholic group also showed a significantly smaller
amplitude N550 component at a frontal site compared with controls; however, the latency of
the component did not differ between the groups. The P2, N350 and P900 components measured
at Cz showed no group differences for amplitude or latency. Rundell et al. (1972) studied seven young
men over three nights of drinking with alcohol administered over an hour, ending 30
minutes before bed, with blood alcohol concentrations at bedtime between 0.05 and 0.095 mg
percent. Data are presented from a baseline night, three drinking nights and the mean of
two recovery nights. Prinz et al. (1980) studied
five young men over nine nights of drinking (seven of them at home) with a 0.8g/Kg dose
(0.08 Breath Alcohol Concentration (BAC) on the laboratory nights) consumed over the hour
before bedtime.

For example, administration of the tumor necrosis factor α
(TNF-α) antagonist etanercept led to normalization of REM sleep in 18 abstinent
alcoholics (Irwin et al. 2009). In patients with delirium tremens (DTs), a higher percentage of Stage 1 sleep with REM (stage 1 period with low voltage EEG with REM) was demonstrated (Greenberg and Pearlman, 1967). In this study, one of the subjects had nightmares of hallucinatory intensity during alcohol withdrawal and with 100% Stage 1-REM sleep. As DTs ended, recovery sleep set in as a response to sleep deprivation in most of these patients. However, a subset of patients may have fragmented sleep and disturbances of consciousness that predict a guarded prognosis for future episodes of DTs (Kotorii et al., 1982, Nakazawa et al., 1981).

Alcohol and Insomnia: Definition, Statistics and Risks

Frontal (but not posterior) N550 and P900 amplitudes were smaller
in alcoholics than controls and smaller in men than women, but the sex difference was not
related to diagnosis. Latencies of N550 and P900 did not differ as a function of diagnosis
or sex. The percentage of (A) slow wave sleep (SWS) and (B) rapid eye movement (REM) sleep in the
first half of the night across multiple nights of drinking.

Daytime sleepiness, reduced concentration, irritability, and other symptoms can then result. This article discusses how alcohol affects sleep and the disruptions you might continue to experience after you quit drinking. It also explores why you might feel like you can’t sleep sober and what you can do to cope. Treating anxiety alcohol insomnia can help reduce insomnia and improve overall sleep quality. A 2019 study showed that individuals who sleep for under 6 hours each night have a 20% higher chance of heart attack than individuals who sleep between 6 and 9 hours. Studies estimate that 36–91% of people experiencing alcohol dependence may have insomnia.

Insomnia As A Co-Occurring Disorder

Some individuals find that alcohol consumption can trigger hot flashes and night sweats during menopause. However, more research is necessary to determine whether this is a common occurrence. People’s tolerance to alcohol as a sleep aid rapidly increases, leading to insomnia and alcohol dependence. Older research suggests the effects on REM sleep appear to be dose related. Low and moderate doses of alcohol tend not to affect REM in the first half of sleep, while high doses of alcohol significantly reduce REM sleep reduction in the first part of sleep.

  • Conversely, the “morning” type individual (greater morningness) prefers an earlier bedtime and an earlier rise time.
  • In this study, SDB was a significant contributor to sleep disturbance in a substantial proportion of male AD subjects above the age of 40 years (Aldrich et al., 1993).
  • That said, some people with insomnia turn to alcohol as a method of self-medicating.
  • “As the levels decline, you’re going to get more issues with the fragmentation,” said Dr. R. Nisha Aurora, a member of the board of directors of the American Academy of Sleep Medicine.
  • Drinking can be especially dangerous for people with obstructive sleep apnea, who wake up many times during the night as their airways momentarily collapse.

Primarily, alcohol abuse reduces sleep quality and disrupts the body’s ability to enter different sleep stages. When alcohol reduces sleep quality it can cause people to wake up in the middle of the night and make sleep less refreshing. In this population based setting, drinking high volumes of alcohol or drinking hazardously may contribute to the prevalence of sleep problems in older age.

Heart rate increase

Data are drawn from (Feige et al. 2006; Prinz et al. 1980; Rundell et al.
1972). Studies have found that people in recovering tend to sleep poorly, have less slow-wave sleep, and increased wakefulness, resulting in less restorative sleep and daytime fatigue. Chronic alcohol use appears to be linked to an increased risk for sleep apnea, especially among drinkers who snore. While Insomnia can lead to a dependency on alcohol, the opposite, like many mental disorders, is also true. In general, the use of alcohol can prevent someone from falling into deep sleep, which is crucial to maintaining normal brain function, physical health, and emotional well-being. The toll this takes could already cause strain to one’s life and relationships.
