“Long-term use of alcohol produces sleep deprivation because it prevents an individual from having deep, refreshing sleep,” he adds. Alcohol typologies and chronic sleep problems (reported on three or more phases) over 30 years follow up (adjusted for age). Alcohol typologies and chronic sleep problems (reported at 3 or more phases) over 30 years follow up. “Keeping a fixed wake-up time and using your prescribed OSA therapy, even on weekends, and going to bed when you feel sleepy will help ensure you frequently get enough restorative sleep which can help combat the weekend spike in OSA,” he added. Even sleeping just 45 minutes longer than usual on weekends was enough to increase OSA severity by 47%, the researchers found. Researchers suspect it’s a perfect storm of bad habits, including smoking and drinking, that tend to spike when the workweek winds down.
Individuals frequently report waking up mentally fatigued despite spending sufficient hours in bed. Studies using polysomnography have shown that alcohol-induced REM rebound leads to irregular sleep patterns, with increased REM density and abrupt sleep-stage transitions contributing to disrupted rest. Although alcohol may help you fall asleep faster, it can negatively impact the overall quality of your sleep. Alcohol affects sleep architecture, and drinking before bed may cause sleep disruption. Research indicates that it may take as long as one to two years for sleep to return to normal in abstinent alcoholics and that for some it may never return to normal. As the effects of alcohol wear off, it can cause you to wake up more frequently throughout the night.
Is a Nightcap Before Bed Still Okay?
The rightpanel (KC-) show the result of averaging responses not including K-complexes. However, it’s important to understand that people react to treatment differently. Talk to an addiction specialist to find the right treatment option for you. NREM and REM sleep are responsible for sleep homeostasis, a regulated balance between sleeping and waking. Here at Sleep Advisor, our editorial team utilizes reputable sources and expert feedback to provide well-researched sleep health content. As the alcohol in your system begins to wear off, something called “homeostatic recovery” can occur.
It impacts breathing and snoring
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 before bedtime lowers melatonin levels and interferes with core body temperatures, which in turn impacts sleep quality. To track this rhythm in humans, researchers tend to use measurements of the core body temperature and of the secretion of the hormone melatonin from the pineal gland in the brain, both of which fluctuate in a typical pattern throughout the day. Accordingly, one can also use these measurements to assess alcohol’s effects on the sleep-wake cycle.
When should you stop drinking alcohol to minimize the impact on sleep?
To investigate these issues and identify the mechanisms underlying the relationship between alcohol and sleep remain important tasks, as does documenting alcohol’s effects on other physiological functions during sleep. For several reasons, studies conducted in healthy people sleeping at their usual bedtimes, such as the studies reviewed in this article, do not adequately represent the hypnotic potential of alcohol in people with insomnia. First, in healthy people, sleep latency and sleep efficiency are already optimal, and further improvement is difficult to demonstrate.

Carbonated drinks are absorbed by your body easier, which makes you drunk faster. It’s easier to fall asleep if you do so at the same time each night regularly. Sleep apnea is when throat muscles intermittently relax and block the airway during sleep, leading to symptoms such as snoring. As a result, you may wake up during the night feeling thirsty or needing to use the bathroom more often. These disruptions affect the quality of your sleep, leaving you feeling tired and groggy in the morning.
However, as the alcohol’s effects start to wear off, the body spends more time in light sleep, which is not as sound and may lead to more nighttime awakenings. As a result of these frequent awakenings, people tend to clock fewer hours sleeping after drinking alcohol. While some people find that drinking alcohol helps them fall asleep more easily, alcohol ultimately has a negative impact on sleep. Even in moderate amounts, alcohol consumed in the hours before bedtime can cost you sleep and leave you feeling tired the next day.

Connect with experts and fellow forum members on CPAP, sleep apnea, and all things sleep. Combining alcohol with sedative medications can be dangerous or even fatal as it could lead to hypoventilation or not being able to breathe deeply at night. Your daily habits and environment can significantly impact the quality of your sleep. Although unlikely at the low dose used, caffeine’s own REM-suppressive effects may have been responsible for the REM suppression observed. If you’re looking to reduce any dependency on alcohol for sleep, one crucial step is to improve your sleep alcohol and sleep hygiene instead.
- Another population that typically shows lower levels of SWS compared with healthy young adults are the elderly, but no studies have assessed alcohol’s effects on the sleep of healthy elderly people.
- It’s true that alcohol acts like a sedative but it disrupts your sleep by creating an imbalance between SWS and REM sleep (sleep cycle stages), thus decreasing sleep quality and perpetuating sleep deprivation as a result.
- Unfortunately, the pressures of school and extracurricular activities keep sustainable solutions to the combined sleep and mental health crisis out of reach for many.
The apparently delayed melatonin rhythms are in contrast to the single studyshowing evidence of an advanced body temperature rhythm early in withdrawal (Kodama et al. 1988), although this was more pronounced inalcoholics with comorbid depression. Consuming alcohol before bed can make you feel less refreshed and reinvigorated after sleeping. The effects of alcohol on your body can also increase the likelihood of waking up during the second half of the night. Furthermore, alcohol slows and shallows breathing, relaxing the muscles of the throat and further causing the upper airway to collapse.
- These sleep-related breathing difficulties occur when soft tissues collapse and block the upper airway.
- This effect results from the body’s adjustment to the presence of alcohol during the first half of the sleep period in an effort to maintain a normal sleep pattern.
- Moreover, these effects can accumulate across nights (Roehrs et al. 2000a).
- The homeostatic drive prompts sleep by boosting levels of adenosine when we’ve been awake for too long.
If sleep issues are lasting weeks or months, it could be time to see a sleep specialist. The problem could be a chronic condition such as sleep apnea, circadian rhythm disorder, narcolepsy or chronic insomnia. This surprised Zeitzer and his colleagues, who thought it would be healthier to live in alignment with one’s “chronotype,” the sleep patterns a person naturally tends toward.
In a recent cross-sectional population study of 187,950 adults in the United States short sleep prevalence was higher among adults who consumed any alcohol compared with those who never consume alcohol18. Our findings contrast with this study in that we did not find strong association between drinking and sleep duration. Jackson et al. note that the prevalence of short sleep across alcohol consumption patterns was more variable among whites, and the majority of Whitehall II participants are white. When puberty hits, there’s a natural shift in circadian rhythms; melatonin production in teens is delayed by about two hours compared with that of younger children and adults. A normal sleep architecture or sleep cycle involves three stages of non-rapid eye movement (NREM) and one stage of rapid eye movement (REM). Alcohol affects sleep in multiple ways and contributes to the appearance of different sleep disorders or to their worsening.
These converted measurements were then summed to define the total weekly number of UK units consumed. Participants who did not drink alcohol in the past year were classified as ‘non-drinkers’. This disruption occurs because alcohol interferes with the brain’s normal sleep regulation processes, affecting neurotransmitters, hormones, and sleep architecture.
