Addiction is a complex condition that can rarely be attributed to a single cause. One’s environment, genetics, mental health, and past experiences all influence the development of addiction. Studies also point out isolation as a vulnerability to drug addiction.  

Social isolation isn’t necessarily bad: we all crave some alone time, at least occasionally. Being alone can be rejuvenating, meditative, and relaxing. But when the solitude is unwanted or unhealthy, it can become problematic. Isolation has become a growing concern for the health care system.

People who are socially isolated may lack friends, family, or close workmates. So, they tend to feel lonely and depressed. As a result, they may suffer from anxiety, low self-esteem, and other mental health issues, as you’ll notice in this article.

What is social isolation?

As the Centers for Disease Control and Prevention put it, social isolation is the lack of social connections that can lead to loneliness in some people. Those in unhealthy isolation are likely to:

• Avoid social interactions – even those that were once enjoyable
• Cancel plans frequently and feel relief when plans are canceled
• Feel distressed when alone
• Spend more time alone or with very limited contact with others
• Experience panic or anxiety when thinking of social interactions

In some cases, the isolation can include emotional isolation where one is unwilling or unable to share their feelings with others. When this happens, the person can become emotionally numb.

What causes social isolation?

Isolation can be a result of many factors, including:

• Death: Loss of a loved one
• Intimate partner violence: When one isolates to avoid contact due to unwillingness to reveal their true situation.
• Mental health problems: Issues like low self-esteem, depression, and anxiety may cause or result from social isolation.
• Remote location: Physical separation due to distance, job, etc., can cause people to experience feelings of isolation.
• Social media: When it becomes a substitute for in-person socialization or meaningful conversation.
• Unemployment: The shame that comes with not getting a job or losing a job can cause people to self-isolate.
• COVID-19 physical distancing measures: The sudden, severe reduction in social interaction cause many people to feel lonely.

The effects of isolation

Many studies have shown a connection between isolation and physical health issues. Isolation is a risk factor for issues like heart disease, increased inflammation and stress hormones, diabetes 2, and even disability. An analysis of 70 studies and 3.4 million people pointed out that isolated individuals had a 30% higher risk of dying in the next seven years.

But the effects of isolation aren’t just physical. They can be mental as well. In fact, numerous studies show a close link between isolation and mental disorders like low self-esteem, depression, social anxiety, dementia, or other mental health concern.

Again, isolation and mental issues tend to feed off of each other. Meaning, an individual might develop anxiety because of isolation, then feel more isolated because of their anxiety, and vice versa.

How isolation leads to addiction

Connecting with other people is an important part of well-being. Humans are social creatures, and not getting enough social interaction can impact health. Isolation can increase the amount of stress hormone cortisol in the body, causing a range of physical health concerns.

Prolonged isolation can lead to mental health issues or worsen the existing ones. When feelings of loneliness go unresolved, it could lead to a range of mental illnesses.

Many studies show a strong connection between mental health disorders and substance use disorders. In fact, as the National Institute on Drug Use puts it, many people who develop mental illnesses are also diagnosed with substance use disorder. Data show high rates of SUD and mental disorders like anxiety, depression, PTSD, and antisocial personality disorders, all of which are common among those who self-isolate. NIDA also points out that people with personality, substance use, and mental disorders were more likely to use non-medical prescription opioids

Isolation may also cause loneliness. When a person is lonely, they may turn to drugs to pass the time or shut down the critical inner voices that tend to multiply in isolation. Speaking of voices, too much isolation leads to fluctuations in thinking, causing one to perceive the world around them negatively. In some cases, the loneliness can make them a little vulnerable, causing them to start looking for reasons people aren’t hanging out with them.

At this point, self-disgust sets in to offer a handy scapegoat. When one fixates on these beliefs and thoughts, they might act in ways to reinforce their actions. They may also abuse substances to cope with their situation or avoid reality. Prolonged use might lead to addiction, driving one further into isolation.

Note that both drugs and social interaction can stimulate one’s dopamine response. Emotional and physical connectedness triggers the production of good feelings, and when that system doesn’t change, one may seek to self-medicate. So they’ll turn to illegal drugs, prescription drugs, or alcohol. For those struggling with addiction, this can make for a deadly mix under the wrong circumstances.

Unfortunately, at this point, any attempt to stop using ends in withdrawal symptoms. So, one is likely to struggle alone, with no end in sight.

How to overcome isolation

Going out more and making new friends might seem like an obvious thing to do in this case. However, isolation can have an underlying cause that needs to be addressed to build more fulfilling connections. Treatment programs exist to help individuals gain control of their lives. But one can also try out the following:

• Do the things they enjoy
• Show compassion and kindness to themselves
• Work on emotional regulation

How to prevent relapse in isolation

Those who go through substance abuse treatment need physical, emotional, and financial support from their loved ones to regain full control of their lives. Otherwise, they risk relapsing. Finding support in groups like Alcoholic Anonymous and Narcotics Anonymous can help prevent relapse.

Getting help for social isolation and addiction

The risks of drug addiction are higher among those suffering from isolation. But the good news is that there are facilities that provide medically-reviewed addiction treatment and therapies to help one reopen communication lines and feel less isolated.
