sleep deprivation and alcohol

Poor sleep quality and insufficient TST have been shown to exacerbate associations between college drinking and negative drinking consequences of risky drinking 240,241,242. In a 2-month prospective study of 157 college drinkers, students who reported higher sleep-related functional impairment experienced consistently high levels of negative drinking consequences, regardless of their risky drinking levels 242. For a review of the relationship between sleep problems and adolescent AUD, see Hasler et al. 243. For problem drinkers, alcohol problem severity was predictive of the Pittsburgh Sleep Quality Index global score for sleep disturbance 244.

Selection of Studies

Suffice it to say that more research is needed regarding the safety and effectiveness of benzodiazepine receptor agonists for the short-term management of insomnia in alcohol dependent patients (13). In an analysis of the Medical Outcomes Study data, the measure of alcohol use was limited to a dichotomous categorical definition–no history of use, past or current use (1). In addition, the preponderance of cross-sectional studies limits conclusions regarding causal direction.

The acute effects of alcohol on decreasing sleep latency, increasing SWS, and increasing EEG delta power can possibly be explained by the GABA receptor agonist properties of alcohol. Alcohol exposure leads to the presynaptic release of GABA throughout the CNS. Within the thalamus, the hyperpolarizing effect of GABA causes the opening of low-threshold Ca2+ ion channels and a pattern of synchronized burst firing that manifests as sleep spindles on the sleep EEG. The further release of GABA causes greater levels of hyperpolarization and the production of delta EEG waveforms 98. The subsequent withdrawal of tonic input to the reticular nucleus allows the release of GABA and inhibition of thalamo-cortical circuits 99. These effects, plus the alcohol-induced release of GABA in the brainstem 100, may also play a role in alcohol’s suppression of REM sleep in the context of high doses of alcohol.

Overlap of Alcohol-Related Insomnia with Other Psychiatric Disorders

Those effects of alcohol on the biological clock appear to persist even without additional drinking, according to research. However, it is for persistent insomnia, which can lead to alcohol relapse, that better and safer treatments are needed. Benzodiazepines produce tolerance and lose their sleep-promoting properties within 2 weeks. Physical dependence and withdrawal phenomena occur with long-term use of benzodiazepines, and all medications in this class can cause rebound insomnia following discontinuation. No studies have demonstrated the hypnotic efficacy of benzodiazepines beyond 12 weeks. For these reasons, benzodiazepines should probably be considered only after alternative therapies have proven ineffective (84).

Tonic and Phasic Periods of REM Sleep

Additionally, the driving scenarios used demonstrate to a significant extent situations from which the project findings can be extrapolated. A simplistic scenario was chosen to allow generalising to motorway driving which is important because drivers experience the greatest risk during monotonous motorway drives 63. The order of experimental conditions was not randomised or counterbalanced so the study cannot discount the possibility of order affecting the results. Participants were however, given a pilot session to familiarise themselves with the test battery and moreover, the tests themselves were simplistic to eliminate the risk of practice effects. If these had occurred, an improved performance would be expected after each repeated exposure to the test battery. Yet, it can be confidently said that the observed results were minimally influenced by practice because of the pattern they produced.

Does alcohol cause insomnia or poor sleep?

These cautions probably apply to the nonbenzodiazepines as well, although studies of their chronic use and abuse in recovering alcoholic populations are limited. Men and women who consume two or more drinks per day had two-to threefold increase in periodic leg movements that fragment sleep (66). Alcohol may also provoke sleepwalking, especially when taken in combination with methylphenidate, diphenhydramine or amitryptiline (67). Alcohol consumption can induce gastritis, esophageal reflux and polyuria that can disrupt sleep. Finally, more frequent awakenings during the second half of the night (often from thirst and polyuria) may lead to un-steadiness and falls during nighttime trips to the bathroom, particularly among the elderly. Glutamate is the major excitatory neurotransmitter in the CNS—that is, the interaction of glutamate with its receptor activates the signal-receiving neuron to generate a new nerve signal.

You can take many steps to improve your sleep, and if those aren’t successful, you should see your healthcare provider. They can determine whether or not you have sleep deprivation, how severe the issue is and why it’s happening, and then offer treatment recommendations. If you have sleep deprivation, it’s important to work on improving your sleep.

Relationships Between Nocturnal Sleep, Daytime Alertness, and Alcohol-Consumption History

Because insomnia is a risk factor for return of depression as well as alcohol relapse (77), prudent practice would advise that patients with sleep problems receive a thorough evaluation for both mental health and substance use disorders. During a later phase of the same study (Roehrs et al. 1999), the participants also had an opportunity to choose between beverages presented in color-coded cups that contained various alcohol concentrations or a placebo. The participants had previously experienced all of those beverages (i.e., they had taken them one at a time before bedtime on different nights) and were asked to choose the beverage that would best help them sleep. With this approach, the insomniacs generally chose an alcohol-containing beverage, whereas the healthy people chose the placebo-containing beverage. Furthermore, the average nightly alcohol dose self-administered by the insomniacs was 0.45 g/kg (up to 0.6 g/kg was possible), which is similar to the dose previously shown to improve the sleep of the insomniacs and similar to the dose that insomniacs report using at home.

Participants who did not drink alcohol in the past year were classified as ‘non-drinkers’. Chronic sleep problems were defined as those when participants who reported a sleep problem (based on the above dichotomy) at three or more data collection phases over the follow-up period. The Whitehall II study was established in 1985 as a longitudinal study to examine the socioeconomic gradient in health and disease among 10,308 civil servants (6895 men and 3413 women)12. All civil servants aged 35–55 years in 20 London-based departments were invited to participate by letter and 73% agreed.

Evidence suggests that consuming alcohol may decrease the body’s sensitivity to cues, like daylight and darkness, which trigger shifts in body temperature and secretion of the sleep hormone melatonin. These fluctuations play a vital role in the sleep-wake cycle, and when they are weakened—or absent—a person may feel alert when they does alcohol help you sleep want to sleep and sleepy when they want to be awake. Plus, untreated sleep apnea and other chronic sleep disorders put you at a higher risk for health conditions like arrhythmias (abnormal heart rhythm), obesity and Type 2 diabetes, which can all contribute to cardiovascular disease.
