Studies show that heavy or moderate consumption can cause sleep apnea in people who don’t have a sleep disorder. “Given that sleep architecture and efficiency decline with age, it is important to keep in mind that alcohol will further exacerbate these issues.” You should be aware of how alcohol affects you and your sleep schedules. “Keep a sleep log to measure duration and quality and add to that log drink quantity alcohol and sleep and times to see if you notice patterns related to sleep quality,” Mendelson advises.

Nitric oxide and malondialdehyde levels and the superoxide dismutase enzyme activity of hippocampal and cortical tissues (10% wet weight per volume) were performed to determine the level of oxidative stress. The expression of brain-derived neurotrophic factor and calcium-calmodulin dependent kinase II proteins in CC and hippocampus was assayed by means of immunohistochemistry.
Alcohol Can Cause Nighttime Wakeups
Another possibility is that alcohol abuse leads to long-lasting neurochemical changes in the brain stem. Figure 2 (adapted from gives an example of the proportions of wakefulness (pre-sleep and throughout the night), and different sleep stages in alcoholic and control men and women. In the second half of the night, sleep is disrupted, with increased wakefulness and/or stage 1 sleep. It is estimated that alcohol is used by more than one in ten individuals as a hypnotic agent to self-medicate sleep problems .
Alcohol may also exert some of its effects on sleep by influencing the circadian rhythm. 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. Older studies have found that drinking alcohol https://ecosoberhouse.com/ before bedtime lowers melatonin levels and interferes with core body temperatures, which in turn impacts sleep quality. Drinking before bed is also linked with more slow-wave sleep patterns called delta activity, but alpha activity, which indicates wakefulness with eyes closed and often precedes sleep, is turned on at the same time.

Consistent with the reports of reduced SWS, Irwin et al. reported significantly lower NREM delta power (0.75–4 Hz) across the entire night in alcoholics relative to controls, particularly in the first NREM period. Total power in the measured spectrum was also lower, with a trend for lower theta power in the first NREM period in alcoholics. The delta power result was confirmed in the baseline data in (Irwin et al. 2002), although it appeared to be stronger in African American than in European American alcoholics. These lower levels of delta power during NREM sleep could reflect underlying gray and white matter volume deficits and compromised connectivity in the brain that characterize chronic alcoholics, as described later. Laboratory based polysomnographic studies of abstinent alcoholics typically show a pattern of sleep disturbance with increased wakefulness consistent with self-reports of persistent sleep disturbance common in this population. Sleep efficiency is a simple index of the proportion of the time in bed spent asleep and thus a polysomnographic marker of general sleep quality.
