For example, people who use alcohol as a sleep aid have a higher mean daytime sleepiness. Hot flashes or the need to go to the bathroom fragment sleep and, therefore, more chances to suffer insomnia. Most studies on alcohol consumption report an increase alcohol and sleep in slow-wave sleep or deep sleep which consists of stages 3 and 4 of NREM. Cutting back on alcohol is one of the easiest paths to a better night’s sleep. If your nightcap has helped you fall asleep, know that your body will need some time to adjust.

How does alcohol affect obstructive sleep apnea (OSA)
We will continue to monitor and revise this article as new literature is published on sleepwalking. A member of our medical expert team provides a final review of the content and sources cited for every guide, article, and product review concerning medical- and health-related topics. Inaccurate or unverifiable information will be removed prior to publication. Some guides and articles feature links to other relevant Sleep Foundation pages. These internal links are intended to improve ease of navigation across the site, and are never used as original sources for scientific data or information.
Why does alcohol wake you up in the middle of the night?
After drinking, production of adenosine (a sleep-inducing chemical in the brain) is increased, allowing for a fast onset of sleep. But it subsides as quickly as it came, making you more likely to wake up before you're truly rested. It stops deep sleep.

Changes in hormones can lead to symptoms that can disrupt sleep. Alcohol will wreak havoc on the second half of your night’s sleep as once the body has processed the alcohol, it begins to act as a stimulant. Alcohol creates an imbalance between SWS and REM sleep, thus decreasing sleep quality and perpetuating sleep deprivation as a result.

This is partially corroborated in an earlier study on same population. The Whitehall II participants were asked about reasons for change in drinking over the last 10 years and an increase in consumption was cited as a means to help get to sleep was by 6% of men and 5% of women21. In terms of sleep problems, men were more likely to report sleeping less than 7 hours per night than women (63.7% men compared to 54.4% women). However, women were more likely to report trouble falling asleep (69.6% compared to 49.5% men) . Over the thirty years follow up, women generally reported more chronic sleep problems than men . More than half the women studied reported trouble falling asleep, waking tired, and/or waking several times a night. In 2012–2013, 70.9% of the original cohort who were still alive (age range 61–81 years), participated in phase 11.
Effects of Alcohol
That consists of self-medicating with alcohol in order to fall asleep, consuming caffeine and other stimulants during the day to stay awake, and then using alcohol as a sedative to offset the effects of these stimulants. Both lack of sleep and alcohol consumption are common occurrences in a college student’s life. Both of these practices can have negative effects on cognitive abilities, especially when paired together. College students may think that moderate drinking has no negative effects on learning and health. As little as one drink, however, can impair a person’s ability to get a good night’s sleep, which can lead to more significant problems. Chronic alcohol use appears to be linked to an increased risk for sleep apnea, especially among drinkers who snore.
- More than half the women studied reported trouble falling asleep, waking tired, and/or waking several times a night.
- Increased fatigue from a hangover may prompt napping during the daytime, which could interfere with one’s ability to fall asleep and stay asleep that night.
- 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.
- “Alcohol also similarly affects the body’s temperature; causing your body’s temperature to dip slightly, then rise, alcohol-spurned irregularities can contribute to nightmares the same way fevers do,” Medical Daily says.
- They can also estimate how long we spend in different stages of sleep, though their accuracy is questionable — the only truly accurate way to measure sleep stages is using an EEG to track our brain waves.
- Some people with alcohol use disorder may need to undergo a detox, which can be very dangerous and is best done under the supervision of medical professionals.
There are a number of treatments available for obstructive sleep apnea. One is a continuous positive airway pressure machine , which is a mask one wears during sleep. “In this treatment, a machine delivers air pressure through a piece that fits into your nose or is placed over your nose and mouth while you sleep,” the Mayo Clinic says. Other treatment options include nasal masks and surgery to remove excess tissue. Analysis revealed that stress levels were largely consistent for both U.S. and non-U.S.
