How does alcohol affect sleep?

If you’re experiencing sleeping issues, whether related to alcohol consumption or not, consider talking to your health care provider or a sleep specialist. It’s not because I don’t appreciate a glass of wine with a great meal, or a few beers on a hot summer evening. It’s because I know what alcohol can do to sleep and healthy circadian rhythms.

People with alcohol use disorders commonly experience insomnia symptoms. Studies have shown that alcohol use can exacerbate the symptoms of sleep apnea. You can manage the negative effects of alcohol on sleep by giving your body ample time to metabolize alcohol before falling asleep. To reduce the risk of sleep disruptions, you should stop drinking alcohol at least four hours before bedtime. Alcohol may aid with sleep onset due to its sedative properties, allowing you to fall asleep more quickly. However, people who drink before bed often experience disruptions later in their sleep cycle as liver enzymes metabolize alcohol.

  1. Sleep apnea is a common disorder that causes breathing to repeatedly stop and restart during sleep, affecting the amount of oxygen your body gets.
  2. It has a sedative effect that helps you relax and makes you drowsy, so you fall asleep faster.
  3. Alcohol can also sometimes act as a stimulant, making you feel more awake instead of sleepy.
  4. The effects of alcohol largely depend important factors like the amount of alcohol and how quickly it is consumed, as well as the person’s age and body composition.
  5. Conversely, a chronic lack of sleep can leave you with a host of problems.

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. 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.

Does Alcohol Help You Sleep? No, Sleep Expert Explains Why

People with alcohol dependence or going through alcohol withdrawal may experience reduced deep sleep and insomnia. And, unfortunately, insomnia is the most frequent complaint among alcoholics when they give up drinking. Research shows the sleep-promoting effects of alcohol can start to wear off in as little as three days.

You may also wake up more often in the second half of the night, get less sleep in total, and develop sleep disorders, resulting in worse sleep overall — not better. However, the reality is that alcohol has more of an adverse effect on sleep than a positive one. If you’re drinking before bed to help with sleep, you should choose a different relaxation method that will help you achieve better-quality sleep. Typically, an adult needs seven to eight hours of quality sleep at night, though every person is different. In addition to getting a sufficient number of hours of sleep, it’s also essential to maintain a regular sleep schedule. Enzymes in the liver eventually metabolize the alcohol, but because this is a fairly slow process, excess alcohol will continue to circulate through the body.

Sleep and circadian rhythm disruption from alcohol also contribute to next-day tiredness, fatigue, irritability, and difficulty concentrating. Even if it doesn’t present as a full-fledged hangover, alcohol-related sleep loss negatively affects mood and performance. Circadian rhythms affect how the body responds to alcohol, depending on the timing of alcohol intake.

Personalized Sleep Profile

Research also shows that those who drink alcohol before bedtime may experience a rebound in the second half of the night. In this case, they will transition from deep sleep imbalanced in favor of NREM sleep to restless sleep with a shift in favor of longer-than-normal periods of REM sleep. Consuming alcohol could also result in an imbalance in the sleep stages you experience. This deep, slow-wave sleep is critical to getting good-quality rest. However, rapid eye movement sleep (REM) is also a vital part of the sleep cycle, since it aids in mental restoration.

Studies show a direct link between alcohol consumption and OSA, since drinking alcohol causes throat muscles to relax. For a person who already has sleep apnea, drinking alcohol can exacerbate the problem, making for an even worse night’s sleep. If you don’t have an existing case of OSA, drinking even a small amount before bed can cause this issue. 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. Still, you may think drinking before bed is a good idea if you have trouble relaxing and falling asleep. “Even if alcohol initially helps [someone] fall asleep, they may wake up many times throughout the night or not get into a deep sleep,” she continues.

How Does Alcohol Impact Sleep?

Research shows that consuming alcohol — even in a moderate dose — an hour before bedtime can cause a notable reduction in melatonin production. To understand how alcohol impacts sleep, it is important to understand the different stages of the human sleep cycle. The fourth stage, REM sleep, begins about 90 minutes after the individual initially falls asleep. Eye movements will restart and the sleeper’s breathing rate and heartbeat will quicken. Some people may assume alcohol is helpful for sleep, since it has a relaxing, soporific effect. Consuming alcohol can help a person fall asleep because alcohol is a depressant.

The power behind your next best day

Alcohol’s disruptive effect on sleep also make a person more vulnerable to parasomnias. If alcohol is the deciding factor in causing a person to experience a form of parasomnia, you can label it an alcohol-induced sleep disorder. Alcohol can also cause a person to wake up throughout the night, as we’ve seen. This form of insomnia can leave you feeling under-rested, even after what should have been a full night of restful, restorative sleep. Chronic sleep problems are common among people who abuse alcohol long-term.

Addiction is a disease, we have addiction medicine that saves lives.

The point at which that happens depends on how much you drank before bed. If you go to bed with a breath-alcohol concentration in the range of 0.06% to 0.08%, for instance, your body will metabolize the alcohol after four to five hours of sleep. Drinking to excess before bed also plays havoc with the REM sleep stage. Studies indicate an evening of heavy drinking leads to a significant reduction in REM sleep during the first half of the night. Alcohol further increases the effects of sleep apnea by relaxing the muscles in the throat, collapsing the upper airway and lowering oxygen levels. This not only worsens pre-existing sleep apnea but may also lead to episodes of sleep apnea in individuals who previously did not experience it.
