How Beer Affects Your Body And Mind

Drinking a couple of beers can have various effects on your body and health. While some studies suggest that moderate drinking may be beneficial for your heart, other research shows no such benefit and links moderate drinking to diseases like cancer and an increased risk of stroke. Drinking a couple of beers regularly can also lead to weight gain due to the high calorie content of beer. Additionally, it is important to consider the recommended weekly upper limits for alcohol consumption, which are four drinks in one day or 14 per week for men, and three drinks in one day or seven per week for women. Consuming more than these amounts is considered heavy or at-risk drinking and can lead to health problems.

Short-term effects on the body

Drinking a couple of beers can have several short-term effects on the body. Alcohol is a drug, and even moderate drinking can lead to health problems. Firstly, drinking impairs judgement and coordination, increasing the risk of accidents and injuries. It can also cause dehydration, as alcohol is a diuretic, leading to increased urination. This can result in headaches, dizziness, and dry mouth.

Additionally, alcohol affects the digestive system, slowing down the digestive process and impacting nutrient absorption. It can irritate the stomach lining, causing inflammation and discomfort, and can also lead to diarrhoea. Drinking can also impact the cardiovascular system, causing an initial increase in heart rate and blood pressure, followed by a decrease in blood pressure and a drop in body temperature as blood vessels dilate.

The short-term effects of alcohol on the brain include a reduction in inhibitions, which can lead to risk-taking behaviour. It can also impair memory and concentration, and in some cases, cause blackouts. Alcohol also affects the endocrine system, disrupting the production of hormones, including those that regulate metabolism and stress.

It is important to note that the effects of alcohol can vary depending on factors such as the amount consumed, the individual's body weight and metabolism, and any medications they may be taking. It is always advisable to drink in moderation and be aware of the potential risks associated with alcohol consumption.

Long-term health risks

Drinking a couple of beers can have several long-term health risks. According to the World Health Organization (WHO), alcohol consumption contributes to more than 200 different types of diseases and injuries. Here are some of the long-term health risks associated with drinking a couple of beers:

Liver Disease

Excessive alcohol consumption is directly linked to liver disease mortality. Drinking alcoholic beverages, such as beer, can increase the risk of developing liver diseases such as cirrhosis. The severity of alcohol-induced liver disease often depends on factors like drinking patterns, duration, and amount, as well as nutrition and genetics.

Cancer

Drinking beer excessively increases the risk of developing certain types of cancer. Alcohol can elevate estrogen and other hormones associated with breast cancer. Additionally, the empty calories from beer can lead to weight gain, which further increases the risk of obesity and 13 types of cancer, including cancers of the oral cavity, pharynx, larynx, oesophagus, liver, colorectum, and female breast.

Cardiovascular Disease

Heavy drinking is associated with an increased risk of cardiovascular disease, including high blood pressure, heart failure, and cardiomyopathy. According to the Centers for Disease Control and Prevention (CDC), excessive drinking can elevate the risk of specific heart-related issues, such as high blood pressure, stroke, heart failure, and cardiomyopathy, which affects the heart muscle.

Depression and Other Mental Health Issues

Studies suggest that heavy or binge drinking increases the risk of depression and anxiety compared to non-drinkers and moderate drinkers. Alcohol consumption can also interfere with antidepressant medication and contribute to long-term cognitive impairment.

Weight Gain and Obesity

Research shows that heavy drinking or binge drinking can lead to weight gain and an increased risk of obesity. The empty calories in beer can contribute to overall calorie intake, making it easier to consume more calories than intended, potentially leading to weight gain.

Other Health Risks

Excessive beer consumption is also associated with various other health risks, including chronic diseases, alcohol use disorders, social problems, weakened immune system, learning and memory issues, digestive problems, and malnutrition.

Alcohol serving sizes

The effects of drinking a couple of beers depend on various factors, including alcohol content, serving size, and individual tolerance. Understanding standard drink measurements and serving sizes is crucial for responsible drinking and adhering to health guidelines.

Serving sizes for alcohol can vary, and it's important to know how much alcohol your drink contains. The amount of liquid in your glass, can, or bottle may not accurately represent the quantity of alcohol.

In the United States, a "standard drink" or "alcoholic drink equivalent" is defined as any beverage containing 0.6 fluid ounces or 14 grams of pure alcohol. Here are the standard serving sizes for different types of alcoholic beverages:

• Regular beer: 12 fluid ounces (355 milliliters), typically containing 5% alcohol
• Malt liquor or flavored malt beverages (hard seltzer): 8–10 fluid ounces (237-284 milliliters)
• Table wine: 5 fluid ounces (148 milliliters), usually containing 12% alcohol
• Fortified wine (such as sherry or port): 3–4 fluid ounces (89-118 milliliters)
• Cordial, liqueur, or aperitif: 2–3 fluid ounces (59-89 milliliters)
• Brandy or cognac (a single jigger): 1.5 fluid ounces (44 milliliters)
• Distilled spirits (gin, rum, tequila, vodka, whiskey, etc.): 1.5 fluid ounces (44 milliliters)

It's important to note that these standard drink amounts are based on the volume of alcohol and may not align with customary serving sizes. Additionally, the percentage of alcohol by volume can vary within and across beverage types.

Binge drinking

In the United States, binge drinking is typically defined as consuming five or more standard drinks (for men) or four or more drinks (for women) over a two-hour period. This consumption pattern generally leads to a blood alcohol concentration (BAC) of 0.08% or higher. However, the number of drinks required to reach this BAC level can vary depending on factors such as age, size, and gender. For example, younger individuals and women tend to reach the binge drinking threshold with fewer drinks.

Frequent binge drinking can lead to brain damage faster and more severely than chronic drinking. This is due to the neurotoxic effects of very high levels of glutamate released during a binge, resulting in excitotoxicity, which damages or kills brain cells. Each episode of binge drinking immediately harms the brain, and the damage accumulates with repeated episodes. Adolescents, particularly those in early adolescence, are thought to be especially vulnerable to the neurotoxic effects of binge drinking, as their brains are still developing.

Addressing binge drinking is crucial due to its harmful effects on individuals and society. Interventions and prevention programs aimed at reducing binge drinking among adolescents and young adults are essential to mitigate the negative health, social, and economic consequences associated with this behavior.

Risky drinking

The 2016 documentary Risky Drinking examines the risks of alcohol consumption and how the medical community is addressing and treating "risky drinkers". The film takes an intimate look at the stories of four individuals and the impact of alcohol on their lives, showcasing the different stages of heavy drinking that people may go through. Nearly 70% of American adults consume alcohol, and almost a third of them will engage in problem drinking at some point in their lives.

The film, produced by HBO Documentary Films and the National Institute on Alcohol Abuse and Alcoholism (NIAAA), aims to spark a conversation about identifying risky drinking and offering alternatives to the one-size-fits-all approach that prevents many from seeking help. Through storytelling, expert commentary, and animation, Risky Drinking presents a new perspective on alcohol use and misuse along a broad spectrum of risk. It also provides life-saving information on how to help individuals reduce or stop their drinking.

The NIAAA defines "at-risk" or "heavy" drinking based on both the amount consumed on any given day and the frequency of heavy drinking days. Binge drinking and certain drinking patterns can also put individuals at risk. Additionally, as people age, they may become more sensitive to alcohol's effects. The film highlights the need to re-evaluate drinking habits and provides resources for those seeking treatment and support.
