The Effects Of Alcohol On The Brain And Body – Do you enjoy a glass of wine every now and then? You are not alone. More than 85% of adults indicate that they have ever drunk alcohol. In 2020, alcohol consumption rose in the US, with heavy drinking among women increasing by 41%.
Although occasional drinking is unlikely to cause health problems, moderate or heavy drinking can affect the brain. And alcohol abuse can cause deficiencies over time.
The Effects Of Alcohol On The Brain And Body
Alcohol quickly affects your body. It is absorbed into your bloodstream through the lining of your stomach. Once there, it spreads to tissues throughout your body. Alcohol reaches your brain in just five minutes and starts to affect you within ten minutes.
Alcohol’s Impact On Your Brain And Heart
After 20 minutes, your liver starts to process alcohol. On average, the liver can metabolize 1 ounce of alcohol every hour. It takes about five and a half hours for a blood alcohol level of 0.08, the legal limit for alcohol consumption, to leave your system. Alcohol remains in the urine for up to 80 hours and in the hair follicles for up to three months.
“Intoxication occurs when alcohol intake exceeds your body’s ability to metabolize and break down alcohol,” says Jeffrey T. Johnson, DO, Northwestern Medicine Regional Medical Group certified addiction medicine specialist.
Your whole body absorbs alcohol, but it really takes a toll on the brain. Alcohol disrupts the brain’s communication pathways. It can also affect the way your brain processes information.
The impaired judgment you have when you drink alcohol can make you think you can still drive, regardless of your BAC. Drivers with a BAC of 0.08 or more are 11 times more likely to die in a single vehicle crash than non-drinking drivers. Some states impose higher penalties for people driving with a high BAC (0.15 to 0.20 or higher) due to the increased risk of fatal crashes.
The Science Of What Alcohol Does To The Brain At Three Most At Risk Ages
Your body’s response to alcohol depends on many factors. These include your age, gender, overall health, how much you drink, how long you have been drinking and how often you normally drink.
Over time, excessive drinking can lead to psychological problems, such as depression and anxiety. Alcohol abuse can increase your risk of certain cancers, as well as serious and possibly permanent brain damage. It can lead to Wernicke-Korsakoff syndrome (WKS), which is characterized by memory loss, extreme confusion and vision problems. WKS is a brain disorder caused by a thiamine deficiency, or vitamin B-1 deficiency. Taking certain vitamins and magnesium, along with not drinking alcohol, can improve your symptoms.
Alcohol can damage your body in many ways. The good news is that within a year of quitting drinking, most cognitive damage can be reversed or improved.

I think many consider wine/alcohol to be a natural sedative. After Dave’s death, I brought wine to almost every meal delivered by friends. And to be honest, I have drank from a glass a few times, but for me it is far from a normal routine. And this is not because of the idea of brain damage, because I didn’t have this information from Doctor Daniel Amen and his extensive research yet, but it was more about wanting to feel + be in reality. I knew that the depth of my grief would require profound change to not feel it, and I just wasn’t willing to take the risks that come with it.
Scans, along with various studies, reveal the many ways alcohol affects the brain. Decreased blood flow to the brain, limited reproduction of brain cells, increased risk of dementia, hippocampal atrophy and more. Add to that even more anxiety and brain fog.
So yes, it can calm your nerves for a short period of time, but it sounds to me like a very temporary anesthetic with great potential to lead to much more disturbing circumstances.

Of course, it’s time to invest in finding your way through your grief. Know better + do better! Light to moderate alcohol consumption has long been linked to better heart health, but the exact reasons behind this link have remained a mystery. Despite the known health risks associated with alcohol, including a higher risk of cancer and neurological aging, researchers at Massachusetts General Hospital have shed light on one possible explanation. Their recent research, published in the Journal of the American College of Cardiology, shows that alcohol can reduce stress signals in the brain, resulting in less strain on the heart.
To unravel this phenomenon, scientists pored over data from more than 50,000 individuals from the Mass General Brigham Biobank, a comprehensive research database. Their findings confirmed that light to moderate drinking was indeed associated with a significant reduction in cardiovascular disease risk. Importantly, the extensive scale of this study allowed them to rule out extraneous factors, such as socioeconomic status, physical activity and genetics, that often complicate smaller-scale research. It became clear that something unique was going on, a discovery that was further illuminated by examining the participants’ brain scans.
These brain scans showed that alcohol can have lasting effects on stress levels in the brain, relieving the heart of excessive strain even days after the last drink. The brain’s stress network is like a tug-of-war, with the amygdala, responsible for emotions, on one side and the prefrontal cortex, which controls executive functions, on the other. During stressful situations, the amygdala sends distress signals, while the prefrontal cortex can inhibit the amplification of this alarm throughout the body, including the heart.
Alcohol Related Brain Damage
Dr. Ahmed Tawakol, study author and co-director of the Cardiovascular Imaging Research Center at Massachusetts General Hospital, noted that alcohol is known to alleviate the amygdala’s alarm response. However, the researchers asked a unique question: Does it have long-term effects on these systems? Analyzing brain scans of more than 1,000 study participants, they found that light to moderate drinkers experienced a persistent reduction in amygdala activity, with prefrontal cortex activity unaffected when there was no alcohol in their system. Although the data did not allow researchers to determine whether this effect on the amygdala would diminish if individuals stopped drinking altogether, this dampening of amygdala activity was associated with a notable 22% decrease in the risk of cardiovascular disease .
Furthermore, when the researchers specifically examined light to moderate drinkers with a history of anxiety, characterized by an overactive stress network, they saw a doubling of the effect. Dr. Tawakol explained: “Instead of the 22% reduction, people with prior anxiety had a 40% reduction in heart disease.” However, he stressed: ‘I know a lot of people will hear that and say, ‘Well, I’m worried. That’s why I drink. I think it has a benefit.’ But there is no safe amount of alcohol.”
While these findings are intriguing, Dr. Tawakol that there are alternative, safer ways to utilize this stress-reducing path. For example, exercise is currently being studied by Tawakol and has been shown to increase activity of the prefrontal cortex, achieving similar stress reduction benefits. Getting enough sleep also works in a similar way. Dr.’s ultimate goal However, Tawakol is identifying pharmacological interventions that can safely reduce amygdala activity. He emphasized the need to go beyond conventional recommendations such as “get more sleep and exercise” in light of this new pathway that, when targeted, could double the reduction in cardiovascular disease risk. Alcoholism, also called alcohol use disorder or alcohol addiction, is a condition characterized by the inability to stop or control alcohol use, despite the negative effects it has on a person’s life, health and well-being.
The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), describes the major criteria that qualify someone as an alcoholic, including:
Alcohol, Even In Moderation, Could Harm Your Brain
According to the Centers for Disease Control and Prevention, nine in 10 excessive drinkers are not dependent on alcohol.
Many people who drink a lot of alcohol are not considered alcoholics, and many people who drink can drink in moderation.
Some people may be alcoholics but are unaware of the severity of their problem or even deny that there is a problem.
Many alcoholics do not see their drinking as a problem. Because drinking is so common in social settings in the United States, it is also difficult for people to understand that excessive drinking can quickly become a serious health problem.

It is also possible that someone has a drinking problem, but can still function normally at work, school or at home. Sometimes this is called a “high-functioning alcoholic,” and it can be very difficult to tell that the person needs help.
