Alcohol and depression are often linked, but the relationship between the two is complex and not fully understood. Some people with depression may turn to alcohol to self-medicate and alleviate their symptoms. Others may develop depression as a result of excessive alcohol consumption. Understanding the connection between alcohol and depression can help you navigate appropriate treatments and coping skills.

How Does Alcohol Impact the Brain?

In the short term, alcohol activates the brain’s pleasure and reward system while reducing the systems responsible for stress and pain, making it easy to overuse. Consistent heavy alcohol use can cause long-term damage, impacting areas of the brain responsible for memory, motivation, impulse control, sleep regulation, attention, and more.¹

Why Do People Turn to Alcohol When They’re Depressed?

Alcohol often serves as a readily available and socially accepted coping mechanism for negative feelings. It can temporarily dull the pain, providing a brief escape from feelings of sadness, anxiety, and hopelessness associated with depression. For example, someone who is going through a rough breakup might start drinking excessively to suppress the feelings of heartache and loneliness.

Some may use alcohol to self-medicate, attempting to manage their symptoms on their own without seeking professional help. In these cases, a social drink may turn into a habit and then into dependency. For example, a person feeling helpless and unable to sleep might start having a glass of wine every night as a sleep aid. Over time, the quantity may increase as the body develops a tolerance, and soon, the person might find that they can’t fall asleep without alcohol.

It’s important to remember that while alcohol might provide short-term relief, it is not a solution for depression. In fact, it can exacerbate the condition and create a vicious cycle of depression and alcohol misuse.

Can Alcohol Cause Depression?

While not a sole cause on its own, for someone who already has other risk factors for depression, alcohol can lower serotonin levels and other important neurotransmitters that stabilize someone’s mood. Long-term use can make someone more vulnerable to developing depression due to this factor.² Plus, if someone is using alcohol as their main coping mechanism, they’re likely also suffering from lack of deep sleep and not getting proper social supports, both of which can also worsen depression.³

The Ways Alcohol Can Worsen Depression

Alcohol can intensify depressive symptoms and complicate the path to recovery for various reasons, including:

• Physiological impact: Alcohol is a central nervous system depressant, which essentially means it can lower serotonin and norepinephrine levels—neurotransmitters that help regulate mood. Thus, excessive alcohol intake can lead to heightened feelings of sadness, lethargy, and hopelessness, all of which are hallmark signs of depression.
• Poor sleep quality: While alcohol might initially help you fall asleep, it disrupts the sleep cycle and prevents deep, restorative stages of sleep, which is critical for mental well-being. The result is often exacerbated fatigue and worsened depressive symptoms.
• Increased risk of impulsive behaviors: Alcohol impairs judgment and lowers inhibitions, which could lead to reckless behavior, including self-harm or suicide, especially in those already struggling with depression.
• Interference with antidepressants: Alcohol can interfere with the effectiveness of prescribed antidepressants, rendering them less effective at managing depressive symptoms.
• Alcohol-induced anxiety: Regular, heavy drinking can lead to alcohol-induced anxiety, which can occur during withdrawal and even long after withdrawal, deepening the cycle of depression and alcohol use.

If you are feeling suicidal or experiencing a mental health crisis, please reach out for immediate support by contacting your local emergency services, visiting your local emergency room, or calling/texting the National Crisis Hotline at 988.

Treatment for Co-Occurring Depression & Alcohol Use

Treatment for depression and alcohol use typically involves detoxing from alcohol use, then receiving therapy and medication to work through the depression symptoms.

It’s important to note that the cessation of significant alcohol consumption should be done with the supervision of a medical professional. Quitting quickly or without proper support can be dangerous and lead to significant health risks.

Treatment for co-occurring alcohol use and depression could include:

• Stopping alcohol use: Talk to your doctor or present to a formal rehabilitation program, especially if you were drinking heavily. It’s important to get regimented, professional support for this issue.
• Medication: A psychiatric provider can prescribe medication to help alleviate some symptoms of depression and side effects of the alcohol use. This may involve antidepressants, which work to boost serotonin and norepinephrine levels in the brain, both of which may have been diminished by alcohol use.
• Therapy: Behavioral therapies like cognitive behavioral therapy (CBT), dialectical behavioral therapy (DBT), and behavioral activation can all help you understand the links between your thoughts, feelings, and behaviors, and work toward develop positive coping skills.
• Support groups: Being able to talk with others who have gone through similar circumstances can be incredibly helpful during recovery.
