Lippman and Freedman (1967) studied four young men over three or five nights of
drinking with 1 g/Kg ethanol administered 4 hours before bedtime. Perhaps this is because the number of female hazardous drinkers was notably lower than among male subjects and, therefore, the number of subjects with sleep disorder caused by alcohol might have been too low to yield any statistically significant result. AUDIT-KR scores showed significant correlations with subjective sleep quality, sleep duration, and sleep disturbances in men.

alcohol causing insomnia

Drinking to fall asleep can build a tolerance, forcing you to consume more alcohol each successive night in order to experience the sedative effects. The sleep of individuals with depressive and/or anxiety disorders resembles the sleep of persons with alcoholism (71). Similar REM sleep changes occur does alcohol cause insomnia during withdrawal in alcoholics with and without secondary depression (54). Polysomnography is not helpful in differentiating among these disorders or their treatment, and thus should not be considered a primary diagnostic instrument for patients with psychiatric disorders and sleep complaints.

While this may work for a short time, typically, more alcohol is needed to accomplish this over time. This practice can mask an underlying sleep disorder such as obstructive sleep apnea which may be causing the insomnia in the first place. Circadian rhythms are a manifestation of the activity of the primary endogenous pacemaker, the suprachiasmatic nucleus in the hypothalamus, upon which melatonin acts. Dim Light Melatonin Onset (DLMO) is a commonly used marker for evaluating the activity of the circadian pacemaker and for assessing the changes in circadian phase, i.e. delayed or advanced (Pandi-Perumal et al., 2007).

Insomnia results from a mismatch involving persistent activity in wake-promoting structures during NREM sleep, leading to simultaneous sleep and wake activity along with psychophysiological arousal (Buysse et al., 2011). From a clinical perspective, insomnia occurs in vulnerable patients with predisposing factors, such as having a family history of AD or certain genetic traits. Acute insomnia is triggered in them by stress promoting events (precipitating factors). This acute insomnia becomes persistent because of perpetuating factors such as reading in bed (Spielman et al., 1987) or drinking alcohol. We believe that it would be meaningful to conduct further studies on female subjects to compare the sleep quality between hazardous drinkers or patients with alcohol use disorder and moderate drinkers or persons who do not drink at all. In addition, further studies are recommended focused on the correlation between alcohol consumption and sleep apnea or restless leg syndrome, both of which were found to be significant in the present study.

MeSH terms

The withdrawal then tends to last hours, lessening in severity as times goes on. However, this time can be quite challenging, especially for a suicidal alcoholic. The symptoms of insomnia from alcohol withdrawal also tends to worsen other symptoms, such as mood swings and depression. That is why it is important to get to the roots of what is causing the sleep disorder, as there may be a way to lessen it. Insomnia is a common sleep disorder that causes difficulty falling or staying asleep. Due to the lack of uninterrupted sleep you can experience overnight, you are more prone to feeling excessively tired throughout the next day.

It is well established that particularly dangerous and demanding work, especially when performed at night, is a major stressor on the body and can affect the worker’s overall health and well-being [26,51,52]. Sleep onset occurs when there are increased homeostatic (sleep-promoting) and decreased circadian (wake-promoting) drives (Borbely, 1982). From a general neurophysiological perspective, the onset and maintenance of sleep involves depolarizations of the thalamocortical neural circuits (Saper et al., 2010).
