Our brains rely on a delicate balance of chemicals. As a depressant, alcohol can disrupt the brain’s balance of neurotransmitters, influencing our thoughts, feelings, behaviors, and actions—and sometimes our mental health. Wondering how exactly alcohol affects your mental health and what can you do about it? Keep reading to learn five common psychological effects of excessive alcohol consumption and get tips for balancing drinking and well-being. 

5 ways alcohol affects mental health

Although it might seem like alcohol positively impacts your mental health by giving you a buzz, the long-term effects of alcohol can cause serious mental health problems. Research consistently shows that excessive alcohol use, particularly when it leads to alcohol use disorder (AUD), is linked to a wide range of mental health issues, from anxiety disorders to an increased risk of suicide. Here are five common ways alcohol affects mental health: 

1. Alcohol can worsen anxiety 

If you’re feeling social anxiety at a party, a few drinks may help you feel more at ease, but this feeling is often short-lived—and can ultimately worsen anxiety. As the alcohol wears off, the body’s response to stress and anxiety can become heightened, often resulting in increased feelings of unease and tension. Simply put, the relaxation that someone experiences after drinking wears off fast. 

Research has long shown that chronic alcohol use often co-occurs with anxiety: having AUD increases the risk of developing an anxiety disorder, and vice versa. Recent studies take these findings a step further, showing that anxiety- and alcohol-related mental health diagnoses may share overlapping neurobiological systems. In short, alcohol misuse and anxiety disorders may have underlying brain processes that make each other worse. 

2. Chronic alcohol use is linked to depression 

Like anxiety, the symptoms of depression and regular heavy drinking have been shown to be clinically linked. Research shows that chronic alcohol use can worsen the symptoms of depression, and people with depression may turn to alcohol to relieve their symptoms. 

Also, experts warn that chronic alcohol use can worsen the side effects of some antidepressants, including symptoms like drowsiness and impaired coordination, and keep the medicines from working as well as they should. Also, combining alcohol with antidepressants can—at worst—cause a fatal rise in blood pressure or liver toxicity. 

3. Excessive alcohol use can cause psychosis

In some cases, research shows that acute intoxication, alcohol withdrawal, and chronic alcoholism can cause psychosis, a mental illness marked by hallucinations and delusions. In particular, hallucinations and delusions are more common among drinkers with alcohol dependence who suddenly stop drinking.

4. Alcohol dependence can lead to withdrawal symptoms

When someone who is physically dependent on alcohol stops drinking or drastically reduces their alcohol intake, alcohol withdrawal symptoms can arise. These withdrawal symptoms can impact a person’s physical and mental health and can devolve into a vicious cycle, as the symptoms can make it even harder to stop drinking. Research shows that alcohol withdrawal symptoms can range from mild to severe, including mental health symptoms like anxiety (on the mild end of the spectrum) and hallucinations (on the severe side of the spectrum). Physical symptoms of alcohol withdrawal range from insomnia and gastrointestinal upset to high blood pressure and temperature dysregulation.

5. Alcohol can increase the risk of suicide

Studies show that heavy drinking increases a person’s risk of suicidal thoughts, suicidal attempts, and death by suicide. Because alcohol use makes people lose their inhibitions and act more impulsively, it may lead to dangerous actions, such as self-harm or suicide, research finds. Also, for some people, alcohol may be used as a coping mechanism to deal with an underlying mental health condition or emotional distress, which are risk factors for suicidal ideation and completion. 

When and how to seek help for alcohol use

It’s important to seek support if alcohol use is causing problems in your day-to-day life or affecting your physical or mental health. 

The first step in seeking help is recognizing the signs that alcohol is causing issues in your life. These may include neglecting responsibilities at school or work, relationship issues with friends or family, and any physical or mental health concerns (including those outlined above) exacerbated by drinking. If you’re still unsure if you should seek help for alcohol use, consider the following questions: 

  • Do I typically drink more than I originally intended when I started?
  • Have I tried to quit or cut down on drinking alcohol without success?
  • Have I neglected my work, family, or other responsibilities due to alcohol consumption?
  • Has alcohol use led to conflicts or problems in my relationships with family, friends, or colleagues?
  • Have I experienced physical health issues like hangovers, accidents, or medical conditions related to alcohol use?
  • Do I notice that my mental health, including mood and anxiety, worsens when I drink?
  • Do friends or family express concern about my drinking?
  • Has my overall quality of life been negatively impacted by drinking alcohol?

If you answer yes to any of these questions, it may be worthwhile to pursue professional support. Remember: asking for help is a sign of strength.

After recognizing that you need to seek help for alcohol use, consider reaching out to a trusted healthcare provider, including a primary care physician or a mental health professional. They can discuss your concerns and provide guidance on treatment options. Depending on your needs, a healthcare provider may refer you to an alcohol addiction counselor or a higher level of care (like an inpatient or outpatient program) or encourage you to seek outpatient therapy for co-occurring mental health issues. Another source of support may be an alcohol abuse support group, like Alcoholics Anonymous (AA). 

Once you have a source of professional support, you should reach out to supportive friends and family and share your decision to seek help. These people can encourage you on your journey and serve as a support system as you develop healthier coping mechanisms and prioritize self-care.
