Alcohol and Insomnia: Everything Your Need to Know

These fluctuations play a vital role in the sleep-wake cycle, and when they are weakened—or absent—a person may feel alert when they want to sleep and sleepy when they want to be awake. First off, while wine and other alcohols have notorious sedative effects, it’s important to note that these drinks also have calories, which means they give us energy, too. So while alcohol is being processed, before you begin to feel a bit drowsy, the calories are being converted to energy. Instead of deep, restful sleep, you’re more likely to find nighttime awakenings, lower sleep quality, and reduced sleep efficiency at the bottom of your glass.

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. First, alcohol affects everyone differently because of a slew of factors, like age, biological sex, and body composition, just to name a few. 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.

Alcohol also affects people with central sleep apnea (CSA), which occurs when the brain periodically stops sending certain signals involved in breathing. Alcohol interferes with the brain’s ability to receive chemical messages involved in breathing, which decreases the body’s respiratory drive and increases the likelihood of pauses in breathing. In addition to fragmented, less restful sleep, alcohol can also have an effect on other sleep issues such as insomnia, excessive daytime sleepiness, and sleep apnea. If you fancy a glass of wine with dinner or a nightcap before bed, you might want to cap the Chiante and put the Negroni down — research shows that even low alcohol intake can stymie your sleep. Consuming alcohol regularly before bed can also make it more difficult to sleep, according to a 2016 study in the journal Drug and Alcohol Dependence. Researchers found that chronic or habitual alcohol use before bedtime led to bouts of insomnia.

Maybe you enjoy a glass of beer or wine after dinner, or your weekends include drinking with friends at bars or social events. Alcohol can aggravate breathing-related sleep problems such as snoring and sleep apnea, according to an article published in December 2019 in the journal Current Opinion in Psychology. The authors advised that people with such sleep disorders should avoid having alcohol, especially before bedtime. However, as the enzymes in your liver metabolize the alcohol, removing it from your body, the sedating effect wears off. That leads to a “rebound effect” in which you experience lighter, more disrupted sleep. “People tend to sleep better the first half of the night and then have more sleep fragmentation during the second half of the night,” says Dr. Benjamin.

When Should I Stop Drinking Before Bed?

As a result it may precipitate — or increase the frequency of — parasomnias which occur during this stage of sleep. Large doses of alcohol produce stupefied and comatose sleep as a primary symptom and sleeplessness as a secondary symptom. But alcoholic sleep is at first snoring as if apoplectic; later, not to be roused. In alcoholic insomnia the patient tosses from side to side during nearly the whole night, getting only broken snatches of sleep attended with frightful dreams.

The N3 sleep stage, where we experience slow-wave sleep, is the deepest stage of sleep. REM sleep is vital for healthy brain development, the National Sleep Foundation noted. Not getting enough REM sleep can make concentrating difficult, cause forgetfulness and leave people feeling excessively sleepy during the day. Poor sleep can also contribute to a wide range of health problems, according to the NIH, including obesity, high blood pressure and depression.

Alcohol and sleep: breaking the cycle

Some studies suggest that alcohol can help extend your sleep if these sedative effects are timed with the early phases of sleep, since you’re more likely to fall and stay asleep sooner. But while this may be the case with lower doses of alcohol (lower than a standard drink), there’s evidence that your sleep quality may diminish over the course of the night—especially if you’ve had more than a low dose. 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. Based on data from roughly 160,000 Sleep Foundation profiles, nearly 90% of respondents who regularly consume alcohol in the evening have reported at least one sleep-related problem. Before we look at the effects of alcohol on sleep in detail, here’s the basic bottom line.

And when this happens night after night, you’ll find yourself dealing with insomnia. Breathing problems — Since alcohol’s sedative effect extends to your entire body, including your muscles, it may allow your airway to close more easily while you’re asleep. This can greatly increase the risk of sleep apnea especially if you drink within the last couple of hours before bedtime.

Alcohol is highly effective at suppressing melatonin, a key facilitator of sleep and regulator of sleep-wake cycles. Research indicates that a moderate dose of alcohol up to an hour before bedtime can reduce melatonin production by nearly 20 percent. Alcohol has a direct effect on circadian rhythms, diminishing the ability of the master biological clock to respond to the light cues that keep it in sync. Those effects of alcohol on the biological clock appear to persist even without additional drinking, according to research. During the second half of the night, sleep becomes more actively disrupted. The rebound effect may include more time in REM—a lighter sleep stage from which it is easy to be awakened.

The liver acts as a filtering system for the body, helping metabolize food and chemicals (including alcohol itself), and pulling toxins from the bloodstream. Like nearly all of the body’s organs, the liver functions according to circadian rhythms. Alcohol interferes with these circadian rhythms regulating the liver, and can contribute to compromised liver function, liver toxicity, and disease. Alcohol is the most common sleep aid—at least 20 percent of American adults rely on it for help falling asleep. But the truth is, drinking regularly—even moderate drinking—is much more likely to interfere with your sleep than to assist it.
