Alcohol affects the brain and body in many ways. After experiencing everything from increased confidence and heart rate to diminished reflexes and coordination, many people are left wondering: Is alcohol a depressant, or is it a stimulant?
Scientifically, alcohol is classified as a depressant based on alcohol’s impact on the central nervous system. Understanding alcohol’s effects on mental and physical health is vital for living a safe and healthy life.
What Are Depressants? A Quick Overview
Depressants are a type of controlled substance that is used to treat anxiety, seizures, sleep disorders, and muscle spasms. Depressants slow the activity of the central nervous system, including the brain and spinal cord.
While depressants slow the central nervous system, causing muscle relaxation, drowsiness, and diminished reflexes, other substances have drastically different effects. For example, stimulants increase central nervous system activity, causing increased energy, frequent headaches, and anxiety. Hallucinogens change the way the brain processes stimuli and impact the way a person experiences the world through their senses.
Alcohol's Classification as a Depressant
Alcohol’s classification as a depressant is confusing for some people who have experienced the lowered inhibition and euphoria that can come with drinking alcohol. However, alcohol is a depressant due to the effect it has on the brain and body beyond the initial moments of consumption.
When a person ingests alcohol, they will begin to feel drowsy and confused, with mental and physical functions slowing down more and more with each drink. Those who consume dangerous levels of alcohol put themselves at risk of unconsciousness (also known as “blacking out”), coma, and in the worst cases, death.
How Alcohol Affects the Central Nervous System
Alcohol slows the central nervous system by changing the ways that the neurotransmitter gamma-aminobutyric acid (GABA) impacts the brain. GABA is a neurotransmitter that regulates the nervous system and is essential for communication between the brain and other parts of the body. Alcohol limits the production of GABA, depressing the nervous system and leading to short-term and long-term effects on physical and mental health.
The decrease in GABA production can lead to chronic shifts in how the central nervous system functions and limit the sensitivity of vital receptors. The body attempts to find balance under prolonged exposure to alcohol, and this adaptation leads to alcohol withdrawal syndrome when someone who drinks heavily suddenly stops.
The Impact of Alcohol on Physical Activity
Increased alcohol consumption leads to decreased motor coordination and reaction times. This effect puts individuals at a higher risk of injuries.
Accidents happen, and millions of people die prematurely every year from accidents with a wide range of causes. However, 7% of accident-related deaths globally are connected to alcohol consumption.
Alcohol and Mental Health
Alcohol use, and specifically alcohol use disorder (AUD), is often accompanied by a co-occurrence of other mental health conditions. According to the National Institute on Alcohol Abuse and Alcoholism, the most common mental health disorders that co-occur with alcohol use disorder are:
- Depressive disorders;
- Anxiety disorders;
- Trauma-related disorders;
- Stress-related disorders;
- Sleep disorders;
- Additional substance use disorders.
These co-occurrences can develop in two different ways. First, an individual with a pre-existing mental health condition may use alcohol as a coping mechanism for living with their condition. Second, young individuals and long-time drinkers have been shown to have a higher risk of the development of the mental health disorders listed above.
In short, sometimes mental health conditions lead to alcohol use, and sometimes alcohol use leads to mental health conditions. Either way, it is important to understand these connections when addressing personal alcohol use or the alcohol use of a loved one.
Alcohol's Effect on Sleep and Well-Being
Sleep is necessary for a healthy life. During sleep, the body repairs damaged cells, revitalizes the immune system, stores memories in long-term storage, and processes emotional experiences. A lack of sleep leads to negative shifts in mental health, including:
- Increased depression and suicidal ideation;
- Difficulty regulating emotions;
- Increased risk-taking behavior and poor decision making.
Alcohol use and alcohol dependency are known to cause sleep disturbance and a reduction in deep sleep. For those who are struggling with sleep disturbances and sleep disorders, a reduction in alcohol consumption can have a positive impact on long-term well-being.
The Health Implications of Long-Term Alcohol Use
Prolonged alcohol use is proven to increase the risk of a variety of physical and mental health conditions.
Physically, long-term alcohol use increases the risk of high blood pressure, heart attack, stroke, liver disease, and cancer. Mentally, alcohol increases the risk of serious depressive episodes, anxiety, and suicide.
To avoid these physical and mental health conditions, it is important to limit alcohol intake and pursue treatment for alcohol dependence.
Recognizing Alcohol Dependency and Misuse
Knowing the symptoms of alcohol use disorder is an important step in self-help and community support. These symptoms include:
- Spending a great deal of time drinking, recovering from drinking, and thinking about drinking;
- Falling behind and failing to complete important tasks at work, school, or home due to prolonged alcohol consumption;
- Using alcohol despite extreme risk, such as drinking while driving or drinking while swimming;
- Drinking to avoid symptoms of withdrawal such as shaking, sweating, and pain.
These symptoms are caused by a serious dependence on alcohol. Individuals experiencing these symptoms should reach out to friends and family, local support groups, and medical professionals to address their addiction.
The Role of Awareness and Education
Building awareness of the impact of drugs such as alcohol is an important aspect of public health and education initiatives. According to the National Survey on Drug Use and Health, 19.7% of 14 and 15-year-olds have drunk alcohol at least once in their lifetime. This shows the extent of the interactions that teenagers have with alcohol in their early years.
Education is an intervention tool that can help young people by teaching them about the dangers of excessive alcohol and drug use before they fully move into adulthood.
For adults who are curious about the impact of alcohol on health, education is a fantastic tool for self-improvement. Learning about alcohol, reflecting on one’s relationship with alcohol, and speaking with medical professionals can help individuals create the healthiest life possible.
