Alcohol's Effect: Enhancing Or Distorting Our Emotions?

Alcohol is a depressant that slows messaging between the body and the brain, affecting coordination and concentration. It interferes with the brain's ability to regulate emotions, and its consumption is often linked to underlying mental health issues.

Alcohol initially increases the release of dopamine and serotonin, enhancing feelings of happiness and lowering anxiety. However, excessive drinking negatively impacts emotions, worsening anger, stress, anxiety, and other conditions. It can also lead to depression, pain, and other unfortunate outcomes.

Alcohol can be used to reduce feelings of anxiety, but it actually increases anxiety, especially during a hangover. It also lowers inhibitions and increases confidence.

While alcohol may seem to suppress emotional distress, continuous excessive drinking worsens the situation and makes individuals more vulnerable to alcohol-related disorders.

Alcohol and Brain Chemistry

Alcohol is a nervous system depressant that slows messaging between the body and the brain, affecting coordination and concentration. It depresses the activity of several parts of the brain, including the cerebral cortex, cerebellum, frontal lobes, and hippocampus, making it hard to control judgment, memory, balance, and speech.

Alcohol alters the brain signal transmitters that control emotions, actions, and thinking processes throughout your body. This alteration either suppresses or increases these chemical messengers, slowing your brain activity or changing brain chemicals that enhance emotional stress.

The cerebellum controls functions like memory and emotions. Alcohol forces the body to create an increased amount of serotonin and endorphins, which regulate emotions and our sense of relaxation and happiness. The more often you drink, the more vulnerable your brain becomes to the effects of alcohol, potentially making your moods more volatile over time.

Alcohol also increases Gamma aminobutyric acid (GABA) levels in the brain, resulting in short-term feelings of calm. However, the brain becomes reliant on alcohol, leading to the need to consume increasing amounts to maintain the same emotional state.

Alcohol's effects on the brain vary by sex. Men in human studies show greater adrenocorticotropic hormone (ACTH) and cortisol responses to stress, whereas females show higher autonomic physiological arousal to stress; a greater response to stress cues in the amygdala, insula, orbitofrontal cortex (OFC), and ventromedial prefrontal cortex (VmPFC); and greater VmPFC response to alcohol cues.

Long-term alcohol abuse affects the hippocampus, the part of the brain that regulates emotions, causing reduced ability to control emotions.

Stress and Drinking Alcohol

Stress is a common reaction to feeling threatened or under pressure. While it can be normal and even motivating, it can also cause health issues or be a symptom of them. Drinking alcohol to relax is counter-productive and doesn't help with stress. Drinking more than 14 units of alcohol a week can make feelings of stress harder to deal with. Alcohol is a depressant, which means it negatively disrupts the delicate balance of chemicals and processes in the brain. The more alcohol you drink, the greater the effect on your brain function and mental health.

Alcohol can lead to feelings of being less inhibited, depression, aggression, anger, anxiety, and stress, regardless of your mood before drinking. It also interferes with your sleep, making stress harder to deal with. After drinking alcohol, you may spend less time in the restorative Rapid Eye Movement (REM) stage of sleep, leaving you feeling tired the next day and making feelings of stress harder to deal with.

Alcohol's Effects on Stress

The human body has a complex and extensive process of adapting to harmful or dangerous situations created by stress to keep a physiological balance, a state known as homeostasis. When the body experiences stress, it mobilizes various physiological and behavioral changes via the nervous and endocrine systems to maintain homeostasis and cope with stress. The body's hypothalamic-pituitary-adrenal (HPA) axis system works to maintain a delicate physiological balance, but when alcohol is added to the mixture, it puts the body at greater risk for harm.

Alcohol causes higher amounts of cortisol to be released, altering the brain's chemistry and resetting what the body considers "normal." It shifts the hormonal balance and changes the way the body perceives and responds to stress. Studies have found that cortisol interacts with the brain's reward or pleasure systems, which can contribute to alcohol's reinforcing effects, forcing people to consume greater amounts over time to achieve the same effect. Cortisol also promotes habit-based learning, increasing the risk of becoming a habitual drinker and the risk of relapse.

Alcohol prevents the body from returning to its initial hormonal balance point, forcing it to set a new point of physiological functioning, a process called allostasis. The establishment of a new balance point puts wear and tear on the body and increases the risk of serious diseases, including alcoholism.

Stress and Alcoholism Recovery

Stress can continue to have an effect even after someone stops drinking. Many newly sober people begin drinking again to relieve the symptoms of withdrawal, such as alcohol craving, anxiety, and difficulty sleeping. Researchers are trying to develop medications that will return balance to the body's stress-response system to alleviate alcohol withdrawal symptoms and help prevent relapse in recovering alcoholics.

Who is Most at Risk?

Research has found that men and women who report high levels of stress drink more. Men are 1.5 times more likely to binge drink than women, and 2.5 times more likely to have alcohol use disorders. Abuse during childhood increases the risk for alcohol use disorders in adolescence and adulthood, especially for children who grow up in alcoholic homes.

How to Deal with Stress Without Drinking

• Exercise: Change your scenery and go for a brisk walk or play your favorite sport to help clear your head.
• Challenge your thinking: The way you think affects the way you feel.
• Relaxation methods: Try meditation, yoga, or breathing techniques when you feel worried or anxious.
• Allow yourself some positivity: Take some time for yourself to do something you enjoy. Each day, consider what went well and try listing three things you’re thankful for.
• Writing or talking: Note down your thoughts and feelings or talk to someone you trust about how you’re feeling.

Alcohol and Anxiety

How Alcohol Affects Anxiety

When you drink alcohol, it stimulates the release of dopamine, the "feel-good" chemical in the brain. This can lead to a temporary boost in mood and a reduction in anxiety. However, as dopamine levels dip, feelings of anxiety can rebound and even worsen, especially in individuals prone to anxiety and depression. This rebound effect is known as "hangxiety."

Alcohol also affects the levels of other chemicals in the brain, such as serotonin, GABA (gamma-aminobutyric acid), and folic acid. Changes in these chemicals can impact your mood and increase feelings of anxiety and depression. Additionally, alcohol interferes with your sleep cycle, particularly the REM and paralytic sleep stages, leaving you feeling less rested and potentially exacerbating feelings of anxiety.

The Vicious Cycle of Alcohol and Anxiety

The relationship between alcohol and anxiety can become a vicious cycle. You may drink to relieve feelings of anxiety, but as the effects of alcohol wear off, your anxiety levels can increase, leading you to drink more to find relief again. Over time, this can lead to alcohol dependence, where you rely on alcohol to function in your daily life.

Managing Alcohol and Anxiety

If you find yourself drinking to manage feelings of anxiety, it is important to seek help. Talk to your healthcare provider, as there are effective treatments available, including therapy and medication for anxiety or alcohol use disorder (AUD). Practicing mindfulness, meditation, deep breathing, or exercise can also help you manage your anxiety levels.

Alcohol and Depression

Alcohol is a nervous system depressant that slows messaging between the body and the brain, affecting coordination and concentration. It also depresses the activity of several parts of the brain, including the cerebral cortex, cerebellum, frontal lobes, and hippocampus, making it hard to control judgment, memory, balance, and speech.

Alcohol alters the brain's reward pathways, resulting in alcohol cravings, eventually leading to the brain being unable to function without it (alcohol dependence). Alcohol abuse also affects the hippocampus, the part of the brain that regulates emotions, causing reduced ability to control emotions.

There is a strong link between serious alcohol use and depression. Nearly one-third of people with major depression also have alcohol use disorder. Women are more than twice as likely to start drinking heavily if they have a history of depression. Experts say that women are more likely than men to overdo it when they’re down.

Drinking will only make depression worse. People who are depressed and drink too much have more frequent and severe episodes of depression and are more likely to think about suicide. Heavy alcohol use can also make antidepressants less effective.

The pathways leading to the development of co-occurring alcohol use disorder and a depressive disorder are complex and intertwined. Some individuals may be genetically susceptible to both. For others, symptoms of a depressive disorder can influence the development of an alcohol use disorder. One possible contributor to co-occurrence is that people may alleviate symptoms of a depressive disorder with substances such as alcohol. People who experience major depressive symptoms may start to rely on alcohol to ease their symptoms and feel better, but over time, this can develop into a full-blown alcohol use disorder.

Alcohol can exacerbate depression and depressive symptoms. Depressed study participants who were heavy drinkers displayed worse outcomes from depression treatment; furthermore, even mild to moderate amounts of alcohol appeared to worsen depression, with depressed patients who drank low levels of alcohol experiencing worse outcomes from pharmacological treatments.

The duration of alcohol-induced depression can vary widely. Generally speaking, depressive symptoms associated with alcohol-induced depression have been shown to improve significantly after you’ve abstained from alcohol for a certain amount of time, typically 3-4 weeks in many cases. However, research also suggests that substance-induced depression can turn into independent depression should symptoms of depression persist following cessation of alcohol or other substances of abuse.

Alcohol, Self-Harm and Suicide

Alcohol is a nervous system depressant that slows messaging between the body and the brain, affecting coordination and concentration. It suppresses the activity of several brain parts, including the cerebral cortex, cerebellum, frontal lobes, and hippocampus, making it hard to control judgment, memory, balance, and speech.

Alcohol alters the brain's reward pathways, resulting in cravings and, eventually, dependence. It also affects the hippocampus, which regulates emotions, impairing one's ability to control them. Alcohol increases the levels of gamma-aminobutyric acid (GABA), a neurotransmitter that produces feelings of calm. However, the brain can become reliant on alcohol, leading to abuse and, eventually, addiction.

Excessive alcohol consumption negatively impacts emotions, worsening anger, stress, anxiety, and other conditions. It can also worsen pre-existing mental health issues, such as anxiety, depression, and post-traumatic stress disorder. It is a factor in many violent crimes and suicides.

People may drink to reduce negative emotions, but continuous excessive drinking worsens the situation and increases vulnerability to alcohol-related disorders.

Alcohol, Self-Harm, and Suicide

Alcohol is a significant risk factor for self-harm and suicide. In a study of suicide cases in Cork, Ireland, from September 2008 to June 2012, alcohol consumption was detected in the toxicology of 44% of 307 suicide cases. In another study, alcohol consumption was noted in 21% of 8,145 self-harm presentations.

Self-harm refers to any act of self-poisoning or self-injury, irrespective of motivation. It is a major public health concern, with alcohol use prior to or during self-harm being common. In the UK, more than half of individuals admitted to emergency departments following self-harm will have consumed alcohol.

Volitional alcohol factors, such as drinking to intoxication and negative urgency (the tendency to engage in rash actions to reduce negative emotions), are independently associated with self-harm enaction. Expecting alcohol to lead to outcomes consistent with increasing self-harm risk may also play a role.

Those with a history of self-harm enaction reported more frequent heavy drinking, higher alcohol-related negative urgency, and stronger expectancies that alcohol will lead to negative self-perceptions and markers of self-harm risk.

Strategies for Managing Emotions and Alcohol Use

The first step in managing emotions and drinking is recognizing the need to control alcohol use early. It is important to identify triggers, such as underlying emotional distress, and develop healthier coping strategies and emotional regulation skills. Recovery training and self-management are proven strategies for treating alcohol-related disorders.
