1. Like nearly all of the body’s organs, the liver functions according to circadian rhythms.
2. Binge-drinking – consuming an excessive amount of alcohol in a short period of time that results in a blood alcohol level of 0.08% or higher – can be particularly detrimental to sleep quality.
3. During the second half of the night, sleep becomes more actively disrupted.
4. Using alcohol to cope with social anxiety disorder can be dangerous.

Obstructive sleep apnea (OSA) occurs due to physical blockages in the back of the throat, while central sleep apnea (CSA) occurs because the brain cannot properly signal the muscles that control breathing. As your body metabolizes the alcohol and the sedative effects wear off, it can interfere with your circadian rhythm, and cause you to wake up frequently or before you’re properly rested. In the first half of the night, when the body is metabolizing alcohol, studies alcohol intolerance symptoms and causes show people spend more time in deep, slow-wave sleep and less time in REM sleep. Sleep architecture is biologically driven and finely calibrated to meet the body’s needs during nightly rest—changes to the natural, typical structure of sleep aren’t generally good for health or well being. REM sleep, which gets shortchanged in the first half of the night under the influence of alcohol, is important for mental restoration, including memory and emotional processing.

The sense of relaxation you feel when you drink can often be attributed to your blood alcohol content (BAC). A rise in BAC levels leads to temporary feelings of excitement, but feelings of depression occur as BAC levels fall. As a result, it’s possible that having a few drinks that make your BAC rise and then fall back to normal again can make you more anxious than you were before. Finally, regular drinking has been linked to insomnia and other sleep disorders, especially later in life. Research shows that people with alcoholism find it difficult to recover from traumatic events.

This can make anxiety and stress even more difficult to cope with. Later in the night, as alcohol levels drop, your brain kicks into overdrive. “As the levels decline, you’re going to get more issues with the fragmentation,” said Dr. R. Nisha Aurora, a member of the board of directors of the American Academy of Sleep Medicine. You’ll also probably have more vivid or stressful dreams and — because fitful sleep means that you’re waking up more regularly — you are more likely to remember them.

Alcohol has been linked to reduced rapid eye movement (REM) sleep. Alcohol-induced anxiety can last for several hours, or even for an entire day after drinking. Alcohol changes levels of serotonin and other neurotransmitters in the brain, which can worsen anxiety. Alcohol is a sedative and a depressant that affects the central nervous system.

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. The relationship between sleep apnea and alcohol has been researched fairly extensively. To understand how alcohol impacts sleep, it is important to understand the different stages of the human sleep cycle.

Lifestyle changes to reduce anxiety

Ask your doctor if moderate alcohol consumption is suitable for you. But even if you thud into dreamland, there’s a good chance that too much alcohol will mean a fitful antibiotics and alcohol night of sleep. That’s because alcohol disrupts what’s known as your sleep architecture, the normal phases of deeper and lighter sleep we go through every night.

See how your sleep habits and environment measure up and gauge how adjusting behavior can improve sleep quality. Drinking alcohol in moderation is generally considered safe but every individual reacts differently to alcohol. As a result, alcohol’s impact on sleep largely depends on the individual.

This is possibly because of the effects of alcohol abuse, which can actually change brain activity. Occasionally unwinding with alcohol isn’t necessarily dangerous if your doctor approves. But once you start drinking, you can build a tolerance to the de-stressing effects of alcohol.

Alcohol has sedative effects that can induce feelings of relaxation and sleepiness, but the consumption of alcohol — especially in excess — has been linked to poor sleep quality and duration. People with alcohol use disorders commonly experience insomnia symptoms. Studies have shown that alcohol use can exacerbate the symptoms of sleep apnea.

How much does it take to affect sleep?

But alcohol goes on to affect the entire night of sleep to come. Drinking excessive amounts of alcohol can also have noticeable physical and mental consequences. Over time, consuming too much alcohol can lead to blackouts, loss of memory, and even brain damage (especially if it causes other health problems, such as liver damage). These issues can create more anxiety as you cope with their symptoms. Sleep apnea is a disorder characterized by abnormal breathing and temporary loss of breath during sleep. These lapses in breathing can in turn cause sleep disruptions and decrease sleep quality.

Stimulant and sedative effects of alcohol

Seek help from a mental health professional if you have anxiety.

Researchers from a 2020 study concluded that those with AUD need at least 5–9 months of abstaining from drinking in order to normalize their sleep duration and rhythm, so try to be patient with yourself during this time. Circadian rhythms affect how the body responds to alcohol, depending on the timing of alcohol intake. Long-established research shows the body metabolizes alcohol differently at different times of day. Studies have shown the body is more effective at processing alcohol at certain times of the day than others. Long-term heavy drinkers may be predisposed to developing an anxiety disorder.

Drinking alcohol before bed can increase the suppression of REM sleep during the first two cycles. Since alcohol is a sedative, sleep onset is often shorter for drinkers and some fall into deep sleep rather quickly. As the night progresses, this can create an imbalance between slow-wave sleep and REM sleep, resulting in less of the latter and more of the former. This imbalance decreases overall sleep quality, which can result in shorter sleep duration and more sleep disruptions. 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.
