On the other hand, depressants slow you down by decreasing your heart rate and blood pressure. They can help you feel relaxed and, on the extreme end, completely sedate you (2). With extended use of alcohol over time, there can be long-term concerns, too. Many who abuse alcohol often do it well into the night and oversleep into the next day. In time this may lead to switching up day and night sleeping patterns.

2 Neurochemistry of alcoholism effects

Another possibility is that alcohol abuse leads to long-lastingneurochemical changes in the brain stem. Figure 2 (adapted from (Colrain, Turlington, and Baker 2009b) gives an example of theproportions of wakefulness (pre-sleep and throughout the night), and different sleep stagesin alcoholic and control men and women. Effects of an acute pre-bedtime dose of alcohol on sleep have been extensivelystudied although methodology has varied greatly between studies in terms of dose and timingof alcohol administration, age and gender of subjects, and sample size.

However, while it has some stimulant effects — particularly in low doses — alcohol is mainly a depressant substance. Stimulant effects occur when your blood alcohol concentration (BAC) approaches 0.05 mg/l but are replaced by more depressant effects once your BAC reaches 0.08 mg/l — how to flush alcohol out of your system for a urine test the level at which you’re considered legally impaired to drive in most areas of the United States (3). You should not mix alcohol and stimulant or depressant drugs due to the risk of severe side effects. Some people think of alcohol as a stimulant that can increase your heart rate, give you energy, and decrease your inhibitions. Sedatives and alcohol are sometimes combined recreationally or carelessly.

In the event of an overdose or if combined with another sedative, many of these drugs can cause sleep and even death. You may also experience parasomnias which are disruptive sleep disorders that occur in specific stages of sleep or in sleep-wake transitions. These can happen during arousals from rapid eye movement (REM) sleep or non-rapid eye movement (NREM) sleep.

You may or may not remember them, but they can be lucid or give you a feeling that you are half awake and half asleep.

Prinz et al. (1980) studiedfive young men over nine nights of drinking (seven of them at home) with a 0.8g/Kg dose(0.08 Breath Alcohol Concentration (BAC) on the laboratory nights) consumed over the hourbefore bedtime. Data are reported from a baseline night; the first and ninth alcoholnights and a recovery night. Feige et al. (2006)studied five young men and five young women over three nights of drinking. Alcohol wasconsumed before bed to obtain BAC of 0.03 or 1.0% in two different conditions.Data are presented from a baseline night, three drinking nights and two recovery nights.The results for the first half of the night from these studies are summarized in Figure 1.

Types of sedatives

Feige et al. (2007) reported elevated beta activity in REM and gamma activity instage 2 NREM sleep, but only in data from the adaptation nights, with no differences forsubsequent placebo nights from their drug study. (2002) reported a trend for elevated beta activity in alcoholics across theentire night at baseline that became a significant difference during a recovery nightfollowing a night of partial sleep deprivation. (2009b) did not see any differences between alcoholics and controls in highfrequency EEG activity during sleep. 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).

Since alcohol is a strong depressant that slows brain function and depresses respiration, the two substances compound each other’s actions and this combination can prove fatal. Simply cutting back or giving up alcohol or other drugs can be enough to reverse the negative impacts on your sleep (and can greatly improve your health overall). ”While it’s true that alcohol is a sedative, both having it in your system as well as the process of it wearing off can cause a variety of different problems,” says neurologist and sleep expert Jessica Vensel Rundo, MD. “You’re likely to experience fragmented sleep, insomnia or possibly more serious sleep issues. If you have social anxiety or a social phobia, therapy may work best to reduce your levels of anxiety (combined with a medication such as sertraline, or Zoloft). Occasionally unwinding with alcohol isn’t necessarily dangerous if your doctor approves.

Alcohol is a depressant that affects the central nervous system (CNS). In addition, higher doses of alcohol can suppress dopamine production, which can make you feel sad or listless (3). The left panel(KC+) shows the result of averaging responses that included K-complexes. The rightpanel (KC-) show the result of averaging responses not including K-complexes. Talk to your doctor about alcohol consumption before taking any of these medications, as side effects can be harmful or fatal. Using alcohol to cope with social anxiety disorder can be dangerous.

Others take sedatives recreationally to relax and forget their worries. Barbiturate overdose is a factor in nearly one-third of all reported drug-related deaths. Benzodiazepines comparatively have a wider margin of safety and rarely result in overdose unless mixed with other CNS depressants.[10] Accidental deaths sometimes occur when a drowsy, confused user repeats doses, or when sedatives are taken with alcohol. Sedatives can sometimes leave the patient with long-term or short-term amnesia.Lorazepam is one such pharmacological agent that can cause anterograde amnesia. Remembering names that were earlier known becomes an issue such that the memory loss becomes apparent. In a larger study, Colrain et al. (2009)studied 42 abstinent long-term alcoholics (27 men) and 42 controls (19 men).

For men, sensorimotor gray matter volumemade a significant independent contribution to N550 amplitude with the amount of varianceexplained significantly improving with the addition of diagnostic group. These datasupport the hypothesis that diminished gray matter volume in chronic alcoholismcontributes to an impaired ability to generate large amplitude slow waves, although notall the variance could be explained by loss of volume. Poor connectivity (i.e., deficitsin white matter integrity) likely also contributes, although relations between evokedpotential amplitude and diffusion tensor imaging (DTI) measures of white matter integrityare yet to be tested. Interestingly, in women, while age and temporal gray matter volumeprovided the best model, the addition of diagnosis did not improve the model. The sleep EEG effects in those with long-term alcohol dependence are theopposite to those following acute alcohol administration. One possible mechanism islong-term alteration in responsiveness of GABA mechanisms.

This is possibly because of the effects of alcohol abuse, which can actually change brain activity. Long-term overuse of alcohol can cause physical and psychological dependence. People who are dependent on alcohol may experience withdrawal symptoms when they try to quit drinking. These symptoms may range from nausea and anxiety to seizures and hallucinations. However, in larger doses, alcohol typically causes sluggishness, disorientation, and slower reaction times, as it decreases your mental sharpness, blood pressure, and heart rate.

Alcohol’s effects on the body

Studies of the effects of repeated alcohol administration over multiple nightsare rare and suffer from small sample sizes. To our knowledge, only five such studies havebeen published with a total of 19 men and 5 women evaluated in experiments that vary inthe dose of alcohol administered, the timing of the alcohol relative to sleep, and thenumber of nights of consecutive usage. Sleep occurs over a sustained period, typically lasting approximately 8 hours inhumans. In the absence of continued dosing, alcohol consumed prior to the onset of sleep,therefore, will not be at a constant level throughout the sleep period.

In the second half of thenight, sleep is disrupted, with increased wakefulness and/or stage 1 sleep. It is estimated thatalcohol is used by more than one in ten individuals as a hypnotic agent to self-medicatesleep problems (Arnedt, 2007). An indirect test of the neuronal loss hypothesis of K-complex amplitude deficitin chronic alcoholism was conducted using gray matter volumes from structural MRI dataacquired from the subjects in Colrain et al.(2009). Statistical models were constructed to determine the extent to whichcortical and subcortical volumes could 2cb fly predict evoked potential component amplitudes insleeping alcoholics and controls. Stepwise multiple regression entering age, intracranialvolume, diagnosis, lobar gray matter volumes and subcortical tissue volumes to predictN550 amplitude at Fz produced different models in men and women (Colrain et al. 2011).
