Beer Before Bed: Sleep Or Sleepless?

Alcohol is a drug, and drinking it, even in small amounts, can have adverse effects on your health. While moderate drinking may be linked to certain benefits, such as a reduced risk of heart disease, other research shows no benefit and links moderate drinking to diseases like breast cancer and an increased risk of stroke. Excessive drinking can lead to alcohol use disorder and negatively impact your personal and professional life.

According to the National Institute on Alcohol Abuse and Alcoholism, the upper limit for healthy adults is four drinks in one day or 14 per week for men and three drinks in one day or seven per week for women. Drinking more than these amounts is considered heavy or at-risk drinking and puts you at a higher risk for developing health problems. Binge drinking, which is a pattern of drinking large amounts of alcohol in short periods, is also dangerous and can lead to unintentional injuries, violence, and risky sexual behaviours.

While the occasional beer or two may not be harmful for most people, drinking every day or in excess can have negative consequences. It's important to drink in moderation and be mindful of how much alcohol you consume to lower the risks associated with alcohol consumption.

Two beers a day may be considered excessive drinking for women

Women who engage in excessive drinking are more susceptible to the detrimental effects of alcohol compared to men due to their unique physiological and hormonal characteristics. Pound for pound, women have less water in their bodies than men, which means they absorb more alcohol and end up with a higher BAC. As a result, women are more prone to alcohol-induced blackouts and hangovers than men, even when consuming comparable amounts of alcohol. Additionally, women are more likely to experience long-term negative health consequences from excessive alcohol consumption.

Research has shown that women have a higher chance of developing alcohol-related health issues, both earlier and at lower levels of consumption than men. Alcohol misuse is a leading cause of heart disease, and women are more susceptible to alcohol-related heart disease even if they consume less alcohol over their lifetime. Excessive drinking can also lead to cirrhosis, or permanent liver scarring, and increase the risk of breast cancer by 5% to 15% compared to non-drinkers.

Excessive drinking can also impact a woman's mental health and cognitive function. Studies have shown that alcohol misuse can cause brain damage more quickly in women than in men and disrupt normal brain development during adolescence. Teen girls who engage in heavy drinking may experience a reduction in the size of important brain areas involved in memory and decision-making. Additionally, women may be more susceptible to alcohol-related blackouts, which are gaps in memory caused by high levels of alcohol consumption.

Excessive drinking can lead to unintentional injuries, such as car crashes

Drinking two beers a day may be considered excessive drinking, which can lead to unintentional injuries, such as car crashes. Excessive drinking is typically categorised into two types: binge drinking and heavy drinking. Binge drinking is defined by the CDC as a drinking pattern that raises an individual's blood alcohol concentration (BAC) to 0.08 g/dl or higher. For men, this typically occurs after consuming five or more drinks within two hours, while for women, it is four or more drinks within the same time frame. On the other hand, heavy drinking is defined as consuming at least eight drinks per week for women and 15 or more drinks per week for men.

Excessive drinking, whether through binge drinking or heavy drinking, significantly increases the risk of unintentional injuries. Alcohol impairs judgement and reasoning, slows down reactions, affects balance and coordination, and impairs vision and hearing. These effects can lead to accidents, with car crashes being a primary concern. Drunk driving is extremely dangerous, contributing to a third of all traffic-related fatalities and being the leading cause of death among teenagers. It is important to note that even if you have slept after drinking, there may still be alcohol in your system, impairing your ability to drive safely.

In addition to car crashes, excessive drinking can also lead to other unintentional injuries such as falls, drowning, burns, and poisoning. Alcohol affects balance and coordination, making falls more likely, and its impact on judgement and reasoning can lead to risk-taking behaviours that result in unintentional injuries.

To reduce the risk of unintentional injuries, it is crucial to limit alcohol consumption and plan ahead. This includes avoiding drinking and driving, operating machinery, or swimming, as well as being mindful of potential risks and having a sober support system in place. By following these precautions, individuals can help minimise the chances of unintentional injuries related to excessive drinking.

Drinking two beers a day can increase the risk of certain cancers

The link between alcohol consumption and cancer risk has been well-established by researchers. Studies have shown that drinking two beers a day can increase the risk of breast cancer, with moderate drinkers having a 1.23-fold higher risk compared to non-drinkers. This risk is even higher for heavy drinkers, who have a 1.6-fold higher chance of developing breast cancer.

The risk of other cancers also increases with alcohol intake. For head and neck cancers, moderate drinkers have 1.8 times the risk of oral cavity and pharynx cancers and 1.4 times the risk of larynx cancers compared to non-drinkers. Heavy drinkers have an even higher risk, with 5 times the risk of oral cavity and pharynx cancers and 2.6 times the risk of larynx cancers.

Esophageal cancer risk is also elevated for drinkers, with light drinkers having a 1.3-fold higher risk and heavy drinkers nearly 5 times the risk compared to non-drinkers. Liver cancer risk is approximately doubled for heavy drinkers, and moderate to heavy drinking is associated with a 1.2 to 1.5-fold increased risk of colorectal cancers.

The evidence suggests that the more alcohol a person consumes, and the longer they consume it, the higher their risk of developing an alcohol-associated cancer. Even those who have no more than one drink per day still have a modestly increased risk of certain cancers. Overall, about 5.5% of all new cancer diagnoses and 5.8% of cancer-related deaths are attributed to alcohol consumption.

Drinking two beers a day can be beneficial for heart health

Several studies have suggested that drinking one to two beers per day may help lower the risk of heart disease. Italian researchers found that moderate beer drinkers had a 42% lower risk of heart disease compared to non-drinkers. Another study showed that one drink per day lowered the risk of all-cause mortality for women, while up to two drinks per day produced the same results for men. These findings indicate that drinking one or two beers per day may have positive effects on heart health.

However, it is important to note that these potential benefits are only associated with light to moderate alcohol intake. Heavy drinking can increase the risk of heart disease and stroke. Additionally, any amount of alcohol consumption can be harmful to those who are pregnant, planning to drive or operate machinery, taking medications that interact with alcohol, or living with a medical condition that alcohol could worsen.

While drinking two beers a day may have potential benefits for heart health, it is crucial to consume alcohol in moderation and be mindful of individual health factors and risks.

Two beers a day may be considered moderate drinking for men

Drinking two beers a day may be considered moderate drinking for men. According to the "Dietary Guidelines for Americans 2020-2025", men can drink moderately by limiting their intake to two drinks or fewer per day. This amount is generally considered harmless for most individuals.

It is important to note that moderate drinking does not confer health benefits. While some studies suggest that moderate drinking may be linked to certain advantages, such as red wine's positive impact on heart health, other research disputes these claims. In fact, some studies associate moderate drinking with an increased risk of specific diseases, including breast cancer and stroke.

The definition of moderate drinking also varies depending on the source. For instance, the National Institute on Alcohol Abuse and Alcoholism (NIAAA) defines heavy drinking for men as consuming five or more drinks on any given day or 15 or more drinks per week. In contrast, the Centers for Disease Control and Prevention (CDC) categorizes binge drinking for men as consuming five or more drinks within two hours.

Regardless of the specific definition, it is essential to remember that alcohol is a drug, and excessive consumption can lead to alcohol use disorder (AUD) and various health issues. AUD is characterized by an impaired ability to stop or control alcohol use despite adverse social, occupational, or health consequences. Therefore, it is crucial to monitor alcohol intake and be aware of the potential risks associated with excessive drinking.
