Drinking excessive amounts of alcohol can also have noticeable physical and mental consequences. Over time, consuming too much alcohol can lead to blackouts, loss of memory, and even brain damage (especially if it causes other health problems, such as liver damage). These issues can create more anxiety as you cope with their symptoms.
Alcohol and sleepiness: Possible links
- Researchers theorize that people who experience more stimulating effects and fewer sedative effects are at a higher risk for alcoholism (4).
- Estimatedlifetime alcohol consumption was higher in alcoholic men than women, and the women hadlonger periods of sobriety prior to testing on average.
- A person who is under the influence of one or both of these substances may be more likely to engage in behaviors that could be dangerous since thinking is impaired.
- A young person who drinks alcohol is also more likely to experiment with other drugs, and to run the risk of becoming addicted to them.
- According to the experts, there is no safe level of drinking during pregnancy.
However, consuming alcohol can also cause sleep disruption and other adverse effects on people’s health. Specifically, sedatives make the neurotransmitter called gamma-aminobutyric acid (GABA) work overtime. By upping its level of activity in the CNS, sedatives allow GABA to produce a much stronger effect on your brain activity. It can increase your heart rate, aggression, and impulsiveness, as well as cause a surge in dopamine levels. Furthermore, some people may experience more stimulating effects from alcohol, while others may experience more depressant effects.

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. A person drinking alcohol may experience impaired judgment or slower reaction times. Over time, and with continued artificial interference from alcohol and/or sedatives, the brain may have difficulties regulating these chemicals on its own.
A person should speak with a doctor about healthy alcohol consumption. Naltrexone and acamprosate can both reduce heavy drinking and support abstinence. Individuals with alcohol use disorder (AUD) continue to consume alcohol despite experiencing negative consequences. Although AUD cases may differ in severity, people who receive effective treatment can fully recover.
Furthermore, alcohol overuse can damage the body and may lead to AUD. Consuming too much alcohol too quickly can affect breathing, body temperature, and heart rate. In extreme cases, alcohol poisoning can cause brain damage or even death. 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.
Night awakenings and insomnia
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). 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.
Mixing alcohol with sedatives can also have many lasting health, emotional, behavioral, and social side effects and consequences. Since alcohol and sedative withdrawal can how to wean someone off alcohol be difficult and even potentially life-threatening, medications are often used during medical detox to manage some of the more intense side effects. Instead of stopping “cold turkey,” sedative drugs may be weaned off slowly, for instance. It is important for medical providers to be aware of what substances might be in a person’s system before detox begins in order to minimize complications. Medical detox programs typically last 5-7 days on average; a person can continue straight into a comprehensive addiction treatment program following detox.
Research has found that people’s ability to remember, pay attention, and carry out cognitive functions declines with a lack of sleep. Alcohol consumption can lead to a lack of sufficient quality sleep, which can seriously affect cognitive functions such as learning and memory. Don’t feel like there’s something wrong with you or a loved one with an addiction or that you’re failing yourself or others. Initial doses of alcohol signal your brain to release dopamine, the so-called “happy hormone,” which can cause you to feel stimulated and energized (3). Benzodiazepines are one substance abuse group activities for adults class of depressant drugs used to treat insomnia and anxiety, while prescription opiates are powerful products in this category. The amount of alcohol a person consumes affects them more than the type of alcohol they drink.

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 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).
In addition, higher doses of alcohol can suppress dopamine production, which can make you feel sad or listless (3). A person should speak with a healthcare professional to learn more about healthy alcohol use. People who develop AUD continue to consume alcohol despite experiencing negative consequences. This condition can have a negative effect on health, addiction art therapy ideas relationships, and emotional well-being.
