How Does Alcohol Affect Your Body And Sleep?

Regular alcohol consumption can disrupt sleep patterns and quality of sleep, initially inducing tiredness but ultimately negatively affecting the sleep cycle. Chronic drinking may contribute to sleep disorders, impacting both physical and mental well-being. Before we look at the effects of alcohol on sleep in detail, here’s the basic bottom line. The more you drink, and the closer your drinking is to bedtime, the more it will negatively impact your sleep. Even moderate amounts of alcohol in your system at bedtime alters sleep architecture—the natural flow of sleep through different stages.

What do experts advise about alcohol intake?

That’s right, the traditional “happy hour” time is actually when the body is most prepared to process that cocktail. If that mimosa with brunch hits you particularly hard, it may be the result of circadian timing. The liver acts as a filtering system for the body, helping metabolize food and chemicals (including alcohol itself), and pulling toxins from the bloodstream.

When Should I Stop Drinking Before Bed?

But from a mental health perspective, alcohol is still affecting them negatively. Researchers analyzed information from 20 previously published studies that looked at the effects of alcohol on sleep. Together, the studies included more than 500 people who drank low, moderate or high amounts of alcohol before going to bed, and underwent testing while they snoozed in a sleep lab.

Why Do Alcoholics Often Experience Insomnia?

Over time, poor quality sleep can have a negative influence on many different aspects of your life, including your long-term health. If you’re experiencing sleeping issues, whether related to alcohol consumption or not, consider talking to your health care provider or a sleep specialist. For people who snore or who have sleep apnea—a disorder that causes repeated pauses in breathing during sleep—drinking alcohol tends to aggravate symptoms. Milk contains tryptophan, which helps increase melatonin levels and induce sleep. Drinking warm milk before bed is also a soothing nighttime ritual.

  • And though it may help in the short term, drinking alcohol before bed can actually lead to a night of horrible, restless sleep.
  • If you feel pretty drunk, you’ll probably fall asleep quickly but have a restless night.

  • Even though a glass or two may help you initially drift off faster, it probably won’t benefit your sleep quality in the long run.

«The breathing is inhibited by the fact that the airways are relaxed,» Heinzenberg says. «And sedatives, especially alcohol, even in someone without sleep apnea, reduce those reflexes that are there to keep the airway open.» Moreover, as the alcohol metabolizes and leaves your system, you’re more likely to wake, resulting in less restorative sleep throughout the night. So while, yes, that glass of wine can enhance your sleep on occasion, remember that it’s certainly not a long-term solution to ongoing sleep troubles and can, in fact, exacerbate the issue. Before reaching for that glass, hear from the experts how alcohol before bed might affect your sleep. When people struggle with sleep, they rarely consider alcohol as the culprit.

  • While many previous studies have been done on the topic, researchers in this review restricted their analysis to studies of healthy people who were tested in a sleep lab during the night.
  • Sleep allows the body to recover and renew, improving longevity and lowering the risk of chronic diseases.
  • Generally, females and older adults are at a higher risk for insomnia.
  • It is recommended that alcohol not be consumed in the last four hours before bedtime.

“It’s hard to overstate the importance of sleep, in terms of both quality and quantity,” adds Prof. Myllymäki. From more alarming outcomes such as cancer to more “cosmetic” inconveniences such as premature signs of aging, alcoholic beverages seem to hide a range of toxic effects that can slowly take a toll on our health. Alcohol consumption can lead to a lack of sufficient quality sleep, which can seriously affect cognitive functions such as learning and memory. Researchers believe the link between insomnia and alcohol consumption to be bidirectional, meaning that each contributes to the other. The substance causes sleepiness by increasing the functioning of the gamma-aminobutyric acid (GABA) neurotransmitter.

  • Below, we’ll take a closer look at how alcohol affects the different stages of sleep, as well as how the quantity and timing of alcohol can influence sleep quality.
  • Making a plan to focus on better sleep habits can help you feel your best and improve your overall health.

  • 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.

So after a few drinks, you’re likely to have increased wakefulness and more light sleep. 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.
