How Alcohol Lowers a Person’s Life Span

Oct 11, 2023 | Abuse, Addiction, Alcohol, Substance Abuse

Alcohol has long been associated with socializing and relaxation, to the point where it has become deeply ingrained in every celebration we experience. However, beneath its seemingly harmless allure lies a darker reality – alcohol has the power to significantly reduce a person’s lifespan. 

From adverse health effects to increased risks of accidents and mental health issues, the consumption of alcohol takes a toll on both the body and mind in ways that sometimes cannot be reversed. In this blog, we explore the various ways in which alcohol negatively impacts life expectancy and delve into the importance of moderation or abstinence for a longer and healthier life.

The Impact on Physical Health

Liver Disease: Arguably, the most well-known consequence of excessive alcohol consumption is liver damage. Chronic alcohol use leads to the development of conditions like fatty liver, alcoholic hepatitis, and, ultimately, deadly cirrhosis. As the liver struggles to process alcohol, it can no longer perform its essential functions, thereby reducing the person’s lifespan. 

The reasoning behind this is that the liver and other organs must pause their efforts to take care of other bodily functions in order to prioritize the processing of alcohol. It is a poison to the body, and its job is to eradicate it as soon as possible. This means that digestion and other non-critical processes are forced to go by the wayside.

Cardiovascular Issues: Alcohol abuse can elevate blood pressure, leading to an increased risk of heart disease and stroke. Regular drinking can also raise triglyceride levels, cause irregular heartbeats, and weaken the heart muscle, all of which contribute to a shorter life expectancy.

Cancer: Studies have consistently linked alcohol consumption to various types of cancer, including liver, breast, esophageal, and colorectal cancer. The carcinogens in alcohol damage DNA, promoting the growth of cancer cells. In many cases, cancer can be fatal, especially if it is not caught in time. For those who have genetic links to cancer or are predisposed to certain types of cancer, alcohol can be a direct cause of a shortened life span.

Immune System Suppression: Alcohol weakens the immune system, making us more susceptible to infections and illnesses of all kinds. A weakened immune response can lead to life-threatening conditions in the long run. This means that even the most average illnesses can end up deadly if the immune system is severely suppressed. Chronic drinkers have a heightened risk of succumbing to conditions like the flu due to their decreased ability to fight off bacteria and germs.

The Impact on Mental Health

Depression and Anxiety: While some people may initially turn to alcohol as a coping mechanism for stress and anxiety, prolonged use will typically exacerbate these mental health issues rather than help. The temporary relief from alcohol is outweighed by the long-term negative impact on mental well-being. If left unattended, alcohol use can turn into severe depression or debilitating anxiety.

Memory and Cognitive Decline: Chronic alcohol abuse often leads to memory loss and cognitive impairments, affecting a person’s ability to function on any given day. These cognitive deficits ultimately decrease the overall quality and length of one’s life, as they are subject to consistent forgetfulness and may have to reside with a loved one or in a care facility. Wernicke’s encephalopathy and Korsakoff syndrome are two examples of mental disabilities that can be caused by chronic alcohol use. These conditions result in a dementia-like state that can ultimately be fatal if interventions are not utilized.

Risk of Suicide: Alcohol misuse is strongly linked to an increased risk of suicide, and this is a result of a variety of factors. First and foremost, alcohol lowers inhibition. Specifically, it shuts down our prefrontal cortex, which is responsible for decision-making. In turn, we are subjected to poor decision-making and impulsivity. For those who have prior thoughts of suicide, this could be enough to lower their inhibitions and cause an action that will later be regretted, should it not be fatal. The toxic effects of alcohol on the brain can lead to emotional instability as well, which is dangerous in its own right.

The Impact on Accidents and Injuries

Traffic Accidents: Driving under the influence of alcohol is a major cause of fatal traffic accidents worldwide, whether for the person driving or those around them. Alcohol impairs judgment, coordination, and reaction times, all of which are essential for safe driving. As a result, many people die per year due to buzzed or drunk driving accidents.

Unintentional Injuries: Alcohol consumption causes impaired motor skills, coordination, focus, and balance, increasing the risk of falls, burns, and other unintentional injuries that can be fatal. This could happen inside or outside of the home, at any given time. Accidents can occur in a variety of settings such as swimming or attending an event. Unfortunately, if others are consuming alcohol as well, even being surrounded by bystanders is not always a safeguard.

Social and Economic Impact

Social Isolation: Excessive alcohol consumption can result in strained relationships and loneliness, especially if those around the person affected are against their alcohol use. In turn, they may be rejected by their peers or family. This can cause depression as well as a host of other issues, depending on how isolated the person becomes.

Productivity and Employment: Alcohol use or abuse might cause reduced productivity at work, which could result in job loss over time. For most, this would result in financial hardships and limited access to healthcare. Without health coverage, even the simplest of conditions can end up being life-threatening.

Alcohol, despite its widespread acceptance and social prevalence, carries significant risks that can severely decrease a person’s lifespan. From the damage it inflicts on vital organs to the toll it takes on mental health and its association with accidents, alcohol consumption can cut short lives and diminish their quality. While moderate alcohol consumption may not have such dire consequences, it is of the utmost importance to be mindful of its potential risks and make informed choices about alcohol consumption.

The answer to this issue lies in understanding the potential consequences people who drink alcohol face, seeking help if needed, and promoting a culture of responsible drinking or, in some cases, complete abstinence. Empowering others to make informed decisions about their alcohol intake can contribute to a healthier and longer life all around. Intellectually, we are all aware that drinking can be dangerous. Now, we have a deeper understanding of these specific issues and can teach others to drink responsibly to avoid these potentially life-threatening situations.
