Why Does Alcohol Mess With My Sleep? The New York Times

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. 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. People who go to bed with alcohol in their system may be more likely to wake early in the morning and not be able to fall back to sleep, another consequence of the rebound effect. Alcohol consumption can be a trigger for sleepwalking or talking during sleep. Sleepwalking can lead to injuries, disrupt sleep, and leave a person feeling fatigued and not well-rested after waking.

In short, sedatives and alcohol should not be combined since the possible risk factors and side effects of each substance are heightened by mixing them. Your deep restful sleep tends to be more prevalent in the first few hours but decreases during the second half. 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. If you’re planning on heading out for a night that will involve some drinks, there are some things you can do to help you sleep afterward.

Circadian rhythms regulate nearly all of the body’s processes, from metabolism and immunity to energy, sleep, and sexual drive, cognitive functions, and mood. Some individuals find that alcohol consumption can trigger hot flashes and night sweats during menopause. However, more research is necessary to determine whether this is a common occurrence. Alcohol consumption can lead to a lack of sufficient quality sleep, which can seriously affect cognitive functions such as learning and memory.

Other general adverse effects

An overdose is not the only possible short-term side effect of combining a sedative with alcohol, however. Since combining alcohol and sedatives will enhance the effects of each substance, a person can become much more intoxicated more quickly than if they were just taking one or the other by itself. With extended use of alcohol over time, there can be long-term concerns, too.

1. 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.
2. GABA is an inhibitory neurotransmitter that suppresses the stress reaction, or the “fight-or-flight” response.
3. Drinking alcohol can disrupt the rapid eye movement (REM) phase of sleep, an important, restorative stage of deep sleep during which dreaming occurs.
4. Anyone who’s ever indulged in a drink or two knows that alcohol can make you real sleepy, real fast.
5. Holistic methods can also be helpful as adjunctive and complementary treatment techniques that can aid in relaxation and promote healthy sleep.

Researchers have found that the sedative effect only lasts for the first part of the night, though. People who consume alcohol before bed don’t wake up as often during the first few hours of sleep. It has a sedative effect that helps you relax and makes you drowsy, so you fall asleep faster.

Physical Activity and Sleep

The most effective time of day for the body to metabolize alcohol, according to research? 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. There’s a complicated relationship among depression, alcohol, and sleep. People suffering from depression may already have disrupted circadian rhythms, and the presence of even moderate amounts of alcohol may push those rhythms further out of sync. The gut and its microbiome are often referred to as the body’s second brain, and operate under powerful circadian rhythm activity.

Drinking to excess will typically have a more negative impact on sleep than light or moderate alcohol consumption. Research has shown that those who drink large amounts of alcohol before bed are more likely to take less time to fall asleep, but are also more likely to experience sleep disruptions and decreases in sleep quality. However, since the effects of alcohol are different from person to person, even small amounts of alcohol can reduce sleep quality for some people. Alcohol may aid with sleep onset due to its sedative properties, allowing you to fall asleep more quickly.

What alcohol actually does to your sleep cycles

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. Alcohol can cause sleepiness and may initially have a sedative effect.

It also leads to lighter, more restless sleep as the night wears on, diminished sleep quality, and next-day fatigue. 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.

Studies have shown that alcohol use can exacerbate the symptoms of sleep apnea. 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.

Dopamine is involved in regulating moods and feeling pleasure while also helping to control body movement. GABA is an inhibitory neurotransmitter that suppresses the stress reaction, or the “fight-or-flight” response. When dopamine and GABA levels are elevated in the brain, a person is likely to feel happy and relaxed. Since alcohol and sedative withdrawal can be difficult and even potentially life-threatening, medications are often used during medical detox to manage some of the more intense side effects.

That’s because as alcohol starts to metabolize, the sedative effect wears off. Based on your answers, we will calculate your freeSleep Foundation Score™and create a personalized sleep profile that includes sleep-improving products and education curated justfor you. See how your sleep habits and environment measure up and gauge how adjusting behavior can improve sleep quality. If you pass the moderate threshold, though, you’ll get a lot more of that initial non-REM sleep, but significantly reduce the total percentage of REM sleep over the whole night.

This can greatly increase the risk of sleep apnea especially if you drink within the last couple of hours before bedtime. Over time, and with continued artificial interference from alcohol and/or sedatives, the brain may have difficulties regulating these chemicals on its own. Then, when the alcohol and drugs wear off, withdrawal symptoms can kick in.

The circadian disruption that can result from alcohol consumption contributes to leaky gut syndrome, according to research. Circadian rhythms thrown out of sync can weaken the lining of the gastrointestinal tract, making it more vulnerable to permeation—that’s the leakiness that allows bacteria, toxins, and food to leave the intestines and enter the bloodstream. 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.

An older study concluded that alcohol might reduce sleep in the first half of sleep and increase disruption in the second half. Besides just waking you up a lot, alcohol can disrupt your normal sleep patterns enough to create some longer-term issues you may need to address. If you have alcohol in your system when you hit the hay, you may not sleep very deeply, or for very long, on and off throughout the night.
