They may increase your blood pressure and heart rate and give you more energy. In high doses, they can cause insomnia and make you jittery and impulsive (1). This article reviews the effects of alcohol, both as a stimulant and a depressant. Sedatives and alcohol are sometimes combined recreationally or carelessly.
Side Effects of Alcohol and Other Depressants
- Females ingested 15% less alcohol than males because they typically reach higher BrAC readings even after correcting for body weight [62,63,64].
- Research suggests that light or moderate wine consumption may reduce the risk of dementia, but drinking an excessive amount of wine increases the chance of dementia and cognitive decline.
- How alcohol affects you personally depends on your body chemistry, how much you drink, and your alcohol tolerance.
- Indianapolis health officials have created alerts to learn when an uptick in overdoses has been detected.
- Central nervous system depressants should be used with other medications only under a physician’s supervision.
The more alcohol your drink and the closer you drink it to bedtime, the stronger its effects will be. Consuming alcohol causes physiological changes that affect snorers and people with obstructive sleep apnea (OSA), which occurs when tissues in the nose or throat collapse and temporarily obstruct the airway. It also causes changes to blood vessels in the nose, leading to greater airway resistance in the nasal passages. While some people find that drinking alcohol helps them fall asleep more easily, alcohol ultimately has a negative impact on sleep. Even in moderate amounts, alcohol consumed in the hours before bedtime can cost you sleep and leave you feeling tired the next day.

(1980) reported that REM sleep in the first half of the first drinking night(7.0 ± 3.1%) and of the ninth drinking night (9.5± 3.18%)was lower than baseline (17.26 ± 2.20%), although the difference was notstatistically reliable in this small sample. During the second half of the night, sleep becomes more actively disrupted. As alcohol is metabolized and any of its sedative effects dissipate, the body undergoes what scientists call a “rebound effect.” This includes a move from deeper to lighter sleep, with more frequent awakenings during the second half of the night. (These may be micro-awakenings that the sleeper doesn’t even remember—but they still interrupt the flow, and quality, of sleep.) During the second half of the night, sleep architecture shifts again away from normal, with less time spent in slow wave sleep.
Does Warm Milk Help You Sleep?
Nosex differences in the effects of alcohol on sleep were seen in the group of olderadolescents studied by Chan et al. (Chan et al.2013). In a study of 42 recovering alcoholics (15 women) and 42 controls (23women), we found that women had a better sleep efficiency and more delta activity duringNREM sleep than men, regardless of diagnosis (Colrain,Turlington, and Baker 2009a). Further, estimated lifetime alcoholconsumption predicted percentage of SWS in alcoholic men but not alcoholic women (Colrain, Turlington, and Baker 2009a). Estimatedlifetime alcohol consumption was higher in alcoholic men than women, and the women hadlonger periods of sobriety prior to testing on average.
Alcohol increased CSP duration, which was associated with its biphasic effects
The rebound effect may include more time in REM—a lighter sleep stage from which it is easy to be awakened. 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. It also leads to lighter, more restless sleep as the night wears on, diminished sleep quality, and next-day fatigue.
Nutrition and Sleep: Diet’s Effect on Sleep
Some people think of alcohol as a stimulant that can increase your heart rate, give you energy, and decrease your inhibitions. Sedatives can be used to produce an overly-calming effect (alcohol being the most common sedating drug). In the event of an overdose or if combined with another sedative, many of these drugs can cause sleep and even death. Research suggests that light or moderate wine consumption may reduce the risk of dementia, but drinking an excessive amount of wine increases the chance of dementia and cognitive decline.
Because these analyses are performed on stable sleepepochs, results suggest that once sleep is attained, it is not necessarily characterizedby elevated fast frequency activity. By contrast, primary insomniacs have greater betapower during NREM sleep than normal sleepers, thought to reflect higher levels of corticalarousal (Riemann et al. 2010). Topographicdifferences in EEG spectral power during sleep evaluated in alcoholics compared withcontrols revealed that slow frequency activity was maximal over frontal scalp regions inboth alcoholics and control subjects (Colrain, Turlington,and Baker 2009b). Differences in slow frequency between alcoholics andcontrols were also more marked over the frontal scalp with alcoholics showing lower deltaEEG power (Figure 3). This topographic pattern isconsistent with the known frontal susceptibility to alcoholism-related alterations inbrain structure and function (Zahr et al. 2013;Oscar-Berman et al. 2013).
The gut and its microbiome are often referred to as the body’s second brain, and operate under powerful circadian rhythm activity. 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. 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.
Each EMG epoch lasted 500 ms, with the first TMS pulse occurring 100 ms after the epoch onset. To get a rough understanding of how many drinks it would take you to reach these BAC levels, there are many calculators available online. Stimulants and depressants both affect your nervous system and brain function, although in opposite ways. There is some overlap between the terms «sedative» and «hypnotic».
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 mixing adderall and alcohol: a fatal combination more likely to interfere with your sleep than to assist it. Symptoms of psychological dependence include needing the drug to function and being obsessed with obtaining the drug.
In addition, continued use can lead to physical dependence and, when use is lessened or stopped, withdrawal symptoms. Because all CNS depressants work by slowing the brain’s activity, when an individual stops taking them, the brain’s workings can rebound and race out of control, possibly resulting in seizures and other harmful consequences. Although withdrawal from benzodiazepines can be a difficult experience, it is rarely life-threatening, whereas withdrawal from prolonged use of other CNS depressants can have life-threatening complications. Therefore, someone who is thinking about discontinuing CNS depressant therapy or who is suffering withdrawal from a CNS depressant should speak with a physician or seek medical assistance.
Nicholas et al. (2002) studied 7abstinent long-term alcoholic men meeting DSM – IV criteria for alcohol dependenceand 8 normal control men. Alcoholics were less likely to generate a K-complex in responseto a tone than matched controls. The alcoholic group also showed a potential case of acute ketamine withdrawal a significantly smalleramplitude N550 component at a frontal site compared with controls; however, the latency ofthe component did not differ between the groups. The P2, N350 and P900 components measuredat Cz showed no group differences for amplitude or latency.
For example, they can induce sedation before surgical procedures, and this can range from mild sedation to general anesthesia. Electromyographic (EMG) data were recorded in a tendon-belly arrangement from the right first dorsal interosseous (FDI) muscle. The ground and reference electrodes were placed on the ulnar styloid antidepressants and alcohol interactions process and the distal phalanx of the right index, respectively. The EMG signal was amplified using a 1940 CED amplifier (Cambridge, UK) with a gain of 1000, bandpass filtered between 20 Hz and 1000 Hz (notch filter at 60 Hz; the notch filter was removed to assess the CSP), and digitized at a sample rate of 5000 Hz.
This condition can have a negative effect on health, relationships, and emotional well-being. A therapist can help individuals with AUD develop coping skills to reduce stress and manage cravings. If a person takes depressants for a long time, they may develop physical dependence and substance use disorder.
