Alcohol & Sleep Quality

This process, as well as alcohol’s effect on GABA, may explain reduced sleep latency and the awakenings that can occur once levels of adenosine and GABA return to normal. Anyone who has experienced a restless night after a few drinks can attest to alcohol’s disruptive effect on sleep. Studies prove that alcohol can reduce sleep quality, change sleep patterns, and reduce time spent in one sleep cycle while increasing time spent in another. Though alcohol can increase drowsiness and reduce the time it takes to fall asleep, drinking generally does not have a healthy influence on sleep efficiency or sleep-related bodily functions. Imatoh and colleagues found that the distribution of REM sleep across the night changed significantly with increasing duration of sobriety. In healthy people, the majority of REM sleep occurs during the last third of the night.

First, alcohol affects everyone differently because of a slew of factors, like age, biological sex, and body composition, just to name a few. Alcohol before bed has been shown to lead to fragmented sleep and frequent waking.

The jury’s still out on whether drinking in moderation is good for you, but some studies have suggested that even light drinkers are at risk of cancer due to their alcohol intake. Obviously, the best solution to avoid a disrupted night’s sleep is not to drink, or to have only one or two drinks early in the evening. If you have sleep issues, it might be time to talk to your doctor about conducting a sleep study, to rule out any underlying medical diagnosis. The short answer to the question of alcohol helping us fall asleep is “yes”; however, it’s followed by a big “but.” Yes, alcohol can help you fall asleep,butit will likely cause restlessness during later stages of sleep. First, a quick review of sleep stages, because it’s important to understand what a normal night of sleep looks like, so you can understand how alcohol negatively affects sleep. Finally, regular drinking has been linked to insomnia and other sleep disorders, especially later in life. Researchers have found that the sedative effect only lasts for the first part of the night, though.

However, the bulk of the evidence shows that alcohol doesn’t improve sleep. On the contrary, as alcohol passes through the body, it exerts a number of biochemical effects that tend to lead to poorer sleep. Understanding the effects of alcohol on sleep is the first step toward preventing alcohol-related sleep problems.

If you go to bed with alcohol still in your system, you may experience headaches, frequent awakenings, night sweats, more intense snoring, and nightmares. Whether you have had one or multiple drinks, it’s best to wait for your body to fully process the alcohol before heading to bed. In general, try to avoid drinking alcohol four hours before you plan alcohol and sleep on going to sleep. Alcohol increases levels of adenosine, a key component of the homeostatic drive. The homeostatic drive is responsible for keeping our body balanced, and it’s one of the major mechanisms that regulates the sleep-wake cycle. The homeostatic drive prompts sleep by boosting levels of adenosine when we’ve been awake for too long.

  • Other variables used to characterize sleep are the percentage of total sleep time spent in REM sleep (i.e., REM%) and in SWS (i.e., SWS%), respectively.
  • Armeen Poor, MD, is a board-certified pulmonologist and intensivist.
  • One cocktail after work, a beer in the afternoon, or a glass of wine with dinner will metabolize enough ahead of time not to interrupt, or to minimally interrupt, your sleep.
  • The interpretation of these findings is somewhat limited, however, because the analysis did not exclude people who had other psychiatric disorders prior to the survey that might have contributed to the alcohol abuse.
  • Given the detrimental effects that insufficient sleep has on your body, mind, and quality of life, it is not surprising that people turn to various substances, including alcohol and drugs, to get a good night’s rest.

The combination of several treatment approaches might be especially effective in this respect. Evidence that the GABA system is involved in the sleep disruptions of alcohol withdrawal has been found in studies using agents that mimic GABA’s actions on its receptor (i.e., GABAA agonists). Treatment with such agents during withdrawal should compensate for the reduced baseline activity of GABA that occurs as a result of neuroadaptation.

While A Night Cap Might Help You Fall Asleep, There’s No Guarantee Youll Wake Up The Next Morning Feeling Well

About 30% of people with insomnia report using alcohol to help them sleep. In fact, here are four ways that alcohol can negatively impact the quality of your sleep. When alcohol hits the brain, it impacts a few neurotransmitters including GABA, which helps regulate the nervous system. Alcohol interferes with the body’s ability to produce GABA and mimics its effects, slowing down our brain’s activity. This is when we might notice someone having difficulty speaking or walking after consuming larger quantities of alcohol, or notice them feeling drowsy.

It should not be used in place of the advice of your physician or other qualified healthcare providers. Stayingphysically activeduring the day can help you fall asleep at night, as well as promote overall health.

Stimulants such as caffeine should be avoided, especially at night. Using electronics like TV or smartphones before bed should also be avoided. Eye movement increases, often seeming to jerk around, breathing increases and can be irregular and shallow, blood pressure increases and dreams begin. During this period, learning, memory, and processing functions of the brain are enhanced, affecting a person’s long-term memory capacity. This article explores how alcohol affects your quality of sleep.

Obstructive sleep apnea is a serious disease affecting many Americans. If undiagnosed, it can lead to serious health issues such as stroke, heart disease and hypertension . Alcohol use exacerbates sleep apnea risk because it inhibits your body’s ability to breathe while sleeping. While you may fall asleep quickly, the quality of your sleep suffers under the influence. Alcohol affects multiple processes in your body that prevent you from getting high-quality sleep.

Moderate alcohol consumption 30–60 minutes before bedtime results in disruptions in sleep maintenance and sleep architecture that are mediated by blood alcohol levels. Disruptions in sleep maintenance are most marked once alcohol has been completely metabolized from the body. Moderate doses of alcohol also increase slow wave sleep in the first half of an 8-hour sleep episode. Enhancements in REM sleep and SWS following moderate alcohol consumption are mediated by reductions in glutamatergic activity by adenosine in the central nervous system. In addition, tolerance to changes in sleep maintenance and sleep architecture develops within 3 days of alcohol consumption before bedtime. Several studies during the past 25 years have demonstrated a relationship between baseline sleep problems when patients enter alcoholism treatment and subsequent relapse to drinking.

Strength Training May Be Better Than Cardio For Improving Sleep, Study Suggests

These include breathing issues like sleep apnea, which is linked to drinking. When alcohol has been introduced to the sleep cycle, the functions of the brain are impeded, and the cycles become disrupted. This is particularly true if you drinkwithin an hour of bedtime.

Research from 2012 also found a direct relationship between work-related stress, fatigue levels and insomnia. And though it may help in the short term, drinking alcohol before bed can actually lead to a night of horrible, restless sleep. Because of this, consuming alcohol before bedtime can cause a lot of problems if you snore often or have obstructive sleep apnea. First, let’s take a look at how you can get a good night’s sleep— even if you enjoy alcohol in the evenings.

What If I Cant Sleep Without Alcohol?

However, after four to five hours, alcohol acts as a stimulant rather than a depressant. Drinking alcohol stimulates your brain to produce adenosine, a chemical that helps induce sleep. Unfortunately, the effects of adenosine wear off quickly, and you are more likely to wake up before you have had a full night of rest when you mix alcohol and sleep.

Although SWS% returns to baseline values during withdrawal, researchers should note that baseline values of SWS% in alcoholics are still lower than values from control subjects. REM% decreases with drinking and then returns to or even exceeds baseline levels during withdrawal. Thus, when baseline levels of SWS% were less than 20 percent, heavy drinking produced either no change or a decrease in SWS%.

Why You Should Limit Alcohol Before Bed For Better Sleep

Alcohol impacts the way circadian genes express themselves by reducing levels of molecules that help to manufacture essential proteins. Studies show that circadian rhythm genes may continue to display dysfunctional tendencies even after heavy drinking is stopped. For example, drinking in the evening can increase your likelihood of sleep talking, moving in your sleep, or even sleepwalking. Drinking at night can also cause breathing difficulties such as sleep apnea. Insomnia is a sleep disorder characterized by difficulty sleeping. This can include falling asleep, staying asleep, or getting the quality rest you need to feel rested in the morning. Alcohol relaxes the muscles in your throat, which can make it more likely for your upper airway to become obstructed or collapse.

By capturing data on your habits, your Crescent coach can give you tailored guidance to achieve your health goals. In future articles, we’ll be covering a variety of topics to help you do just that including how exercise, stress, and emotions interact with sleep. Other topics will include how various substances such as THC, CBD impact your sleep, and how lifestyle options such as mocktails, stress management, and sleep strategies can help. Alcohol is a central nervous system depressant, meaning it slows down all of the functions of your brain ranging from thinking to breathing and other automatic functions.

Sleep becomes lighter and less efficient, with more frequent awakenings. Though the disturbances to sleep have a significant impact on the body, not all awakenings will be noticed or remembered by the sleeper. Dehydration from alcohol may cause the heart to beat faster, making sleep more difficult. Decreased REM sleep can affect memory and potentially impact emotional responses during waking hours. Noise, light, and other stimuli are more likely to cause awakening during REM sleep, which can increase daytime fatigue. Consuming alcohol in moderate quantities — approximately one drink a day for women and two for men — could have a beneficial effect on certain biological processes. Moderate drinking may help enhance immune function, especially when the alcohol contains polyphenols such as those present in red wine.

It’s not hard to guess why 20% of American adultsuse alcohol to help them fall asleep—after all, the reasoning behind it seems sound. Consuming even a little bit of alcohol leads to drowsiness in most people, so, for believers in the nightcap, a little drink before bed serves as a way to drift easily into sleep without any tossing or turning.

Does Alcohol Help You Sleep?

At all dosages, your first REM sleep stage is significantly delayed, and you get less REM sleep. Since getting drunk can mean inhibited cognition, slurred speech, stumbling instead of walking, and decreased motor skills, it’s not hard to imagine what it’s doing to your ability to sleep. The bad news is that it’s even worse than you think and a lot more complicated. Also, research shows that people can develop a tolerance to this boozy method within three nights, causing you to need a larger amount of alcohol to get the same effect. REM sleep has a restorative effect and plays a role in memory and concentration. Poor or insufficient REM sleep has been linked to not only grogginess the next day, but also a higher risk of disease and early death.

Even though alcohol may help you fall asleep, it interferes with the quality of your sleep. Alcohol potentially causes a shorter overall sleep time and disrupted sleep, which lead to next-day fatigue and sleepiness. The more alcohol you drink, the greater the negative effects on your sleep.

Get Tested For Sleep Disorders

Excessive alcohol intake can also cause apneas while sleeping, even in people without the condition. But while alcohol can help usher in sleep, it can also disrupt it. Nighttime awakenings, lower sleep quality, and reduced sleep efficiency are common side effects of consuming alcohol, even in moderate doses. But it doesn’t take much alcohol to change sleep patterns and have a detrimental impact on health.
