Alcohol disrupts the natural cycle of sleep stages, which typically alternates between non-REM and REM sleep every 80 to 100 minutes, between four and six times a night. After a night of drinking, you may enter a deeper sleep than usual as soon as you fall asleep and spend less time in REM sleep. As the night wears on, you experience less deep sleep and more light sleep, leading to sleep disturbances and poor-quality sleep. Before we look at the effects of alcohol on sleep in detail, here’s the basic bottom line. The more you drink, and the closer your drinking is to bedtime, the more it will negatively impact your sleep. Even moderate amounts of alcohol in your system at bedtime alters sleep architecture—the natural flow of sleep through different stages.
How to sleep better after drinking alcohol
When your sleep schedule conflicts with your internal clock, you become circadianally misaligned. You can think of the sleep homeostat as a seesaw that wants to be perfectly balanced. During wakefulness, adenosine (a drowsiness-inducing compound) builds up in your brain. This burgeoning sleep pressure tilts the sleep homeostat to one side and pushes you off into sleep when your bedtime rolls around. “It’s possible that during your sleep you are going through alcohol withdrawal or alcohol intolerance that can both lead to night sweats,” he explains; however, this is more for people who over-drink on a regular basis. On average, some people might be sweatier sleepers than others, and when drinking, those effects are only exacerbated, he explains.

This hypothesis has not been directly tested, and it should be notedthat other factors may play a role in the increased REM seen in long-term abstinentalcoholics. For example, administration of the tumor necrosis factor α(TNF-α) antagonist etanercept bromism wikipedia led to normalization of REM sleep in 18 abstinentalcoholics (Irwin et al. 2009). The percentage of (A) slow wave sleep (SWS) and (B) rapid eye movement (REM) sleep in thefirst half of the night across multiple nights of drinking.
0 Possible neurochemical mechanisms of the acute and chronic alcohol effects on sleep
So if you have a horrible nightmare, you might wake up feeling a little on edge, as you’ll remember more of those grueling details. Moderate drinking, defined as one drink for women and two drinks for men per day, can cause sleep disruptions, including a shorter duration of sleep, frequent night awakenings, and disrupted sleep stages. Drinking more alcohol or stronger alcoholic beverages will have a more significant impact on your sleep, with a sharper reduction in REM and deep sleep, leaving you feeling tired and groggy the following day. Alcohol can trigger parasomnias, involuntary sleep behaviors that contribute to poor sleep quality, such as sleep talking and sleepwalking. By interfering with your body’s normal circadian rhythm and sleep cycles, alcohol increases the likelihood of disruptive sleep behaviors that pose a safety risk.
Adverse Effects of Disrupted Sleep
At least that’s the idea behind the “drunken monkey” sleep technique, which encourages you to sway gently back and forth like you’re a little bit tipsy. When you’re drunk, the possibility of you doing something absurd that you barely remember is higher than normal. Finally, put your phone on silent or into airplane mode so notifications don’t wake you. However, if you’re reading this, you probably need to get as much sleep as you can, and probably can’t sleep in. Finally, cutting yourself off early is the smartest thing you can do if you know you need to sleep.

If you tend to pop bottles in the club till four in the morning on Saturdays, you may want to consider corking those bottles a few hours before you hit the sheets. A bad night’s sleep can affect everything from your memory, concentration, to motor control, performance, and mood — these symptoms will only be heightened by the hangover. Cortisol rhythms show no evidence for disruption early in withdrawal or two tofour weeks post drinking in two studies (Mukai et al.1998; Fonzi et al. 1994). However, thosewith delirium tremens did have altered rhythms (Mukai et al.1998; Fonzi et al. 1994). Kuhlwein, Hauger and Irwin (2003) reported lower cortisol early inthe night and higher levels later in the night in their African American alcoholics aftertwo weeks. Studies of the effects of repeated alcohol administration over multiple nightsare rare and suffer from small sample sizes.
Whether or not you’ve eaten affects how quickly alcohol enters your bloodstream. This means that if you go out drinking with a friend who weighs more than you do, your BAC will be higher and it’ll take you longer to sober up even if you both drink the same amount. Keep in mind that it isn’t just the number of drinks you have, but also the type, since crystal meth: signs of use and addiction some bevvies have higher alcohol content than others. The more alcohol you consume, the more alcohol gets into your bloodstream. You’ve knocked back a few drinks and things start looking a little fuzzy. To combat the eventual alcohol-related headache and fight off the early effects of a hangover, take a small dose of ibuprofen when you get home.
Even one drink could increase the chances of a person waking up disoriented or confused. It’s true, sleep may happen more quickly after consuming a drink or two. Alcohol often does reduce sleep onset latency—the time it takes to fall asleep. Depending on how much alcohol is consumed, however, what seems like falling asleep may be something closer to passing out.
Sleep drunkenness is when a person wakes up confused and disoriented, so much so that they are unaware of their behavior. In rare cases, people have harmed themselves or others while sleep drunk. Some people have tried jumping out of a window, and others have shown violent or aggressive behavior. And when your partner mentions your behavior later, you have no memory of it.
- The result is a lot of trips to the bathroom and a (mostly) sleepless night.
- People who go to bed with alcohol in their system may be more likely to wake early in the morning and not be able to fall back to sleep, another consequence of the rebound effect.
- While alcohol may initially make you feel drowsy, it can interfere with your sleep cycle, cause frequent night awakenings, and lead to poor sleep quality.
- The confusion lasts until they fall back to sleep or become fully awake.
So while cutting out drinking will likely benefit your sleep, there may be other factors affecting your shuteye. Even though a glass or two may help you initially drift off faster, it probably won’t benefit your sleep quality in the long run. If you sleep better when you don’t drink, you might consider stopping alcohol use entirely.
If you’re having trouble falling or staying asleep often, see your healthcare provider. They can rule out any underlying cause for your insomnia and recommend the best treatment for you. Finally, going to bed with alcohol in your system increases your chances of having vivid dreams or nightmares, or sleepwalking and other parasomnias.
REM-off cells involve the serotonergic dorsal raphe nucleus and noradrenergiclocus ceruleus. The model originally developed by McCarleyand Hobson (1975) proposed a set of reciprocal interactions between the two groupsof neurons whereby REM-on neurons are influenced by a self-excitatory loop but also have anexcitatory link to REM-off neurons. Once a threshold level of activation is reached in theREM-off cells, they become dominant. These have an inhibitory action on REM-on cells butalso a self-inhibitory feedback loop that progressively decreases their activity.Eventually, activity drops below a threshold point and REM-on cells regain dominance.
During confusional arousal, a person’s behavior may seem a lot like that of someone who’s intoxicated. In fact, a nickname for confusional arousal is «sleep drunkenness.» In adults, episodes of confusional arousal can be caused by a number of habits and conditions, like drinking too much alcohol or taking certain medications. Keep in mind that for people with AUD, sleeping issues may persist through the withdrawal phase.
When sleep is interrupted, we sometimes need a minute to come to; however, there’s a difference between waking up sleepy and waking up disoriented. Contrary to how it sounds, sleep drunkenness has nothing to do with alcohol intoxication. Instead, it relates to feelings of confusion and disorientation when an individual is woken from a alcohol and the brain deep sleep. Alcohol use and dependence appear to interfere with circadian rhythms—biological patterns that operate on a 24-hour clock. Evidence suggests that consuming alcohol may decrease the body’s sensitivity to cues, like daylight and darkness, which trigger shifts in body temperature and secretion of the sleep hormone melatonin.
While this differs based on individual tolerance level and body weight, it’s safe to say that taking 5-7 shots of, let’s say, whiskey, could cause an interference in sleep patterns, says Greuner. Drinking too much is likely to have the opposite effect and leave you feeling groggy and possibly hungover the next day. Alcohol before bed has been shown to lead to fragmented sleep and frequent waking.
