During a normal night of sleep, we cycle through periods of light sleep, deep sleep, and rapid eye movement sleep. Each sleep stage plays an essential function, but deep sleep and REM sleep are considered the most important stages for physical and mental restoration. In addition to loss of gray matter volume and reduced connectivity, down regulation of GABA systems could also partially explain the decrease in both delta power and the amplitude of evoked delta responses in abstinent alcoholics. However, again, there are other possible mechanisms that may also contribute to these effects. Studies of the effects of repeated alcohol administration over multiple nights are rare and suffer from small sample sizes. To help assess how alcohol may be affecting your sleep, experts recommend an alcohol-free reset period, or what Dr. Martin called “an alcohol holiday,” lasting at least two weeks. “It can be very eye-opening to appreciate how much alcohol affects your sleep,” she said.
Does Alcohol Help You Sleep?
Alcohol is a sedative, which means it helps induce sleep. However, this type of sleep is fragmented, and you’re most likely to awaken in the middle of the night when its calming effects wear off.
Consuming alcohol can help a person fall asleep because alcohol is a depressant. As alcohol enters the bloodstream, it introduces chloride ions to neurons, slowing the neurons’ firing. The result is a feeling of relaxation or sleepiness. However, people tend to quickly develop a tolerance to alcohol’s sedative effects, so if you drink regularly, you may not feel sleepy unless you drink to excess. While alcohol can make it easier to fall asleep and stay asleep for a few hours, it’s important to note that alcohol’s sedative effect wears off during the night.
There were no sex differences or interactions between diagnosis and sex for K-complex incidence, P2 amplitude or P2 latency. Frontal N550 and P900 amplitudes were smaller in alcoholics than controls and smaller in men than women, but the sex difference was not related to diagnosis.
Alcohol and Sleep Apnea
U.S. participants reported a similar pattern with depression that their non-U.S. Participants reported alcohol and sleep significant decreases in negative mood and depression the day after the election was called.
This lets our users draw their own conclusions on whether a particular activity led to a poorer or improved quality of sleep and can also let them see certain patterns over time. When alcohol functions like a sedative, making you feel sleepy, drowsy and getting you to fall asleep faster – is it still considered bad for sleep? We will walk you through common questions and misconceptions about alcohol and sleep and break down what alcohol does to the sleeping body at each sleep stage. A hint –alcohol and sleep simply don’t mix well – read on to understand why. Alcohol may make it easier to fall asleep, but it doesn’t improve sleep quality. In fact, it can make our sleep more restless and can decrease our time spent in deep sleep stages.

Most experts agree that drinking will mess with your sleep, no matter your age or gender. And because alcohol depresses the central nervous system, experts caution against using it with sleep aids such as Ambien, Tylenol PM, Benadryl or even supplements like melatonin. The more a person drinks before bed, the stronger the disruption. One to two standard drinks seem to have minimal effects on sleep, Ebrahim says. “Alcohol may seem to be helping you to sleep, as it helps induce sleep, but overall it is more disruptive to sleep, particularly in the second half of the night,” says researcher Irshaad Ebrahim. He is the medical director at The London Sleep Centre in the U.K.
But once you get in the habit of falling asleep without the aid of alcohol, you’ll quickly begin to notice the benefits of longer, deeper sleeps. And the more you work to achieve your alcohol and sleep goals, the better you will feel and the more well-rested you’ll be as you work your unique plan.
