Can Alcohol Cause Insomnia?

The potential for insomnia treatment to influence alcohol-related consequences has significant implications for the prevention and treatment of problematic alcohol use among young adults. However, the problem with alcohol comes later in the night when alcohol has a number of negative effects. Researchers believe the link between insomnia and alcohol consumption to be bidirectional, meaning that each contributes to the other.

So can you use alcohol to help you sleep?

“First of all, it increases our initial deep sleep, disrupting our sleep stages’ overall balance,” he said. In the first half of the night, when the body is metabolizing alcohol, studies show people spend more time in deep, slow-wave sleep and less time in REM sleep. It may sound like a good idea to spend more time in deep sleep. REM sleep, which 10 ways to control high blood pressure without medication gets shortchanged in the first half of the night under the influence of alcohol, is important for mental restoration, including memory and emotional processing. For many people who drink moderately, falling asleep more quickly may seem like an advantage of a nightly glass of wine. But alcohol goes on to affect the entire night of sleep to come.

The Importance of a Good Night’s Sleep

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. And we quickly build a tolerance for the sedative effects of alcohol, which means you may need to drink more to have the same initial sleep-inducing effects.

The circadian rhythm is responsible for keeping the body anchored to a 24-hour cycle. As part of this 24-hour cycle, the body releases a hormone called melatonin to prepare us for sleep in the evening. Older studies have found that drinking alcohol before bedtime lowers 15 tips for staying sober after rehab melatonin levels and interferes with core body temperatures, which in turn impacts sleep quality. In addition to altering your sleep architecture, alcohol can disrupt your sleep by interfering with contributing to sleep disorders and interfering with circadian rhythms.

While heavy alcohol use can trigger insomnia, the opposite is also true. People with insomnia have an increased risk of developing alcohol use disorder, potentially because many individuals turn to alcohol as a sleep aid. For a good night’s sleep, it’s important to leave enough time between you having a drink and going to bed. It takes around one hour for your body to process one unit of alcohol. A pint of lager (4 per cent ABV) or a small (175ml) glass of wine (13 per cent ABV) each contain 2.3 units.

When you don’t get enough sleep, you build up sleep debt and this can tank your energy levels. Some research shows alcohol can make you feel sleepy soon after consumption and this may be due to eating a meal at the same time. Alcohol can also dehydrate you, and even mild dehydration can cause fatigue. 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. Drinking to excess before bed also plays havoc with the REM sleep stage.

Unsurprisingly, studies of people with insomnia have also found that heavy alcohol use exacerbates insomnia. People who wake up feeling unrefreshed may be more likely to rely on alcohol again to help them sleep the next night, leading to a counterproductive pattern of alcohol use. If a person chooses to consume alcohol, drinking in moderation several hours before bed is the best practice for avoiding sleep disturbances. 2020 research suggests that alcohol impacts the part of sleep known as rapid eye movement (REM).

These impairments could mean the danger signs related to substance use — and excess alcohol consumption — are missed. We all know someone who feels merry following their first drink and we know others a review on alcohol who appear unfazed by pint after pint. Alcohol will undoubtedly help to send you off to sleep as it actually works on the same receptors in the brain that are targeted by some sleeping tablets.

The substance causes sleepiness by increasing the functioning of the gamma-aminobutyric acid (GABA) neurotransmitter. The GABA’s main function is to slow down body and brain activity. Studies estimate that 36–91% of people experiencing alcohol dependence may have insomnia. Generally, females and older adults are at a higher risk for insomnia. Individuals with mental health conditions are also more likely to develop insomnia.
