For many people, alcohol is a routine part of social life: a glass of wine with dinner or a beer during the big game. It can be easy to overlook how drinking alcohol affects the body. Whether you drink regularly or only once in a while, understanding alcohol’s effects on your health can help you make more informed choices. Here’s what you should know.
Your Liver Takes the First Hit
When you drink, your liver gets to work breaking down alcohol, but it can only process about one standard drink per hour. When you consume more than that, the excess circulates through your bloodstream until your liver can catch up.
Drinking can cause liver damage, including fatty liver disease, alcoholic hepatitis, and more serious conditions like cirrhosis. Regular checkups with your primary care provider can be essential for monitoring your liver.
Alcohol and Your Heart
While some early research suggested light drinking might offer cardiovascular benefits, this has been debunked due to flaws identified in the analysis of the data. The American Heart Association does not recommend drinking alcohol for any heart health benefit, as it has been linked to many cardiovascular conditions.
What we do know is that heavy drinking raises blood pressure, can trigger irregular heart rhythms like atrial fibrillation, and weakens the heart muscle over time. If you have an existing heart condition, talk with your provider about how alcohol may interact with your care.
Effects on the Brain and Mental Health
Alcohol is a central nervous system depressant, which means it slows brain activity. In the short term, this can affect your coordination, judgment, and reaction time. Over time, regular heavy drinking can alter brain chemistry in ways that contribute to memory problems, difficulty concentrating, increased anxiety, and mood changes.
While some people drink to manage stress or anxiety, alcohol can actually worsen both conditions with regular use. It disrupts the brain’s natural balance of neurotransmitters, which can make feelings of depression or anxiety more intense over time. Connect with a mental health provider to learn more about the connection between alcohol and mental health symptoms.
Sleep Quality Declines
Alcohol may help you fall asleep faster, but it significantly disrupts the quality of your rest. It suppresses REM sleep, the stage of sleep most important for memory, emotional processing, and overall restoration. People who drink regularly before bed often wake feeling tired, even after a full night’s sleep. If you are using alcohol to facilitate sleep, talk with your doctor about other strategies to help sleep become more restful and restorative.
What Moderate Drinking Actually Means
According to the Centers for Disease Control and Prevention (CDC), moderate drinking is defined as up to one drink per day for women and up to two drinks per day for men. A “standard drink” is 12 ounces of regular beer (with about 5 percent ABV), 5 ounces of wine or 1.5 ounces of distilled spirits, each containing about 14 grams of pure alcohol.
It’s worth noting that some individuals should avoid alcohol entirely, including those who are pregnant, taking certain medications, managing specific health conditions, or in recovery from alcohol use disorder with a goal of abstinence.
When to Reach Out for Support
If you’re concerned about your relationship with alcohol or that of someone you care about, you don’t have to navigate it alone. Alcohol use disorder is a medical condition with effective, evidence-based treatments available.
Signs that it may be time to talk to someone include drinking more than intended, difficulty cutting back, continuing to drink despite negative effects on your health or relationships, or relying on alcohol to manage stress or emotions.
