Social isolation is a state of complete or near-complete lack of contact between an individual and society. It differs from loneliness, which reflects temporary and involuntary lack of contact with other humans in the world. Social isolation can be an issue for individuals of any age, though symptoms may differ by age group.
Social isolation has similar characteristics in both temporary instances and for those with a historical lifelong isolation cycle. All types of social isolation can include staying home for lengthy periods of time, having no communication with family, acquaintances or friends, and/or willfully avoiding any contact with other humans when those opportunities do arise.
True social isolation over years and decades can be a chronic condition affecting all aspects of a person's existence. Social isolation can lead to feelings of loneliness, fear of others, or negative self-esteem. Lack of consistent human contact can also cause conflict with the (peripheral) friends the socially isolated person may occasionally talk to or cause problems with family members.
In the case of mood-related isolation, the individual may isolate during a depressive episode only to 'surface' when their mood improves. The individual may attempt to justify their reclusive or isolating behavior as enjoyable or comfortable. There can be an inner realization on the part of the individual that there is something wrong with their isolating responses which can lead to heightened anxiety. Relationships can be a struggle, as the individual may reconnect with others during a healthier mood only to return to an isolated state during a subsequent low or depressed mood.
Research by Cole and colleagues showed that perceived social isolation is associated with gene expression — specifically, the under-expression of genes bearing anti-inflammatory glucocorticoid response elements and over-expression of genes bearing response elements for pro-inflammatory NF-κB/Rel transcription factors. This finding is paralleled by decreased lymphocyte sensitivity to physiological regulation by the hypothalamic pituitary adrenocortical (HPA) axis in lonely individuals, which together with evidence of increased activity of the HPA axis, suggests the development of glucocorticoid resistance in chronically lonely individuals.
Social isolation can be a precipitating factor for suicidal behavior. A large body of literature suggests that individuals who experience isolation in their lives are more vulnerable to suicide than those who have strong social ties with others. A study found social isolation to be among the most common risk factors identified by Australian men who attempt suicide. Professor Ian Hickie of the University of Sydney said that social isolation was perhaps the most important factor contributing to male suicide attempts. Hickie said there was a wealth of evidence that men had more restricted social networks than women, and that these networks were heavily work-based.
A lack of social relationships negatively impacts the development of the brain’s structure. In extreme cases of social isolation, studies of young mice and monkeys have shown how the brain is strongly affected by a lack of social behaviour and relationships.
In a hypothesis proposed by Cacioppo and colleagues, the isolation of a member of a social species has detrimental biological effects. In a 2009 review, Cacioppo and Hawkley noted that the health, life, and genetic legacy of members of social species are threatened when they find themselves on the social perimeter. For instance, social isolation decreases lifespan in the fruit fly; promotes obesity and Type 2 diabetes in mice; exacerbates infarct size and oedema and decreases post-stroke survival rate following experimentally induced stroke in mice; promotes activation of the sympatho-adrenomedullary response to an acute immobilisation or cold stressor in rats; delays the effects of exercise on adult neurogenesis in rats; decreases open field activity, increases basal cortisol concentrations, and decreases lymphocyte proliferation to mitogens in pigs; increases the 24 hr urinary catecholamines levels and evidence of oxidative stress in the aortic arch of rabbits; and decreases the expression of genes regulating glucocorticoid response in the frontal cortex.
Social isolation is both a potential cause and a symptom of emotional or psychological challenges. As a cause, the perceived inability to interact with the world and others can create an escalating pattern of these challenges. As a symptom, periods of isolation can be chronic or episodic, depending upon any cyclical changes in mood, especially in the case of clinical depression.
Every day aspects of this type of deep-rooted social isolation can mean:
- staying home for an indefinite period of time due to lack of access to social situations rather than a desire to be alone;
- both not contacting, and not being contacted by, any acquaintances, even peripherally; for example, never being called by anybody on the telephone and never having anyone visit one's residence;
- a lack of meaningful, extended relationships, and especially close intimacy (both emotional and physical).
- Domestic violence – perpetrator uses social isolation as a means of controlling their victim.
- Family crisis – Mostly occurs when one member of a family neglectfully performs harmful action. For example, if a parent performs any unwillful action against its child, the child could end up in shock, and eventually feeling defeatist. Furthermore, the symptoms could last for the child for an indefinite period of time, with more symptoms uprising.
- Health and disabilities – People may be embarrassed by their disabilities or health problems, such that they have a tendency to isolate themselves to avoid social interaction out of fear that they would be judged or stigmatized. This is common in people who have autism and other known disorders.
- Loss of a spouse – If a spouse has recently separated, divorced, or died, the other person may feel lonely and depressed.
- Living alone – A 2015 study by the National Center for Family & Marriage Research found 13 percent of adults in the United States were living alone, up from 12 percent in 1990. The rate of living alone for people under 45 has not changed, but the rate for Americans aged 45 – 65 has increased over the past 25 years. People over the age of 65 are living alone less often.
- Unemployment – This shows a sign if anyone was recently fired, dismissed, or released from a job or workplace. If the person is unable to seek any future employment (depending on its experience or known fields), the symptoms could be imminent.
- Aging – Once a person reaches an age where problems such as cognitive impairments and disabilities arise, they are unable to go out and socialize.
- Transportation problems – If the person doesn't have transportation to attend gatherings or to simply get out of the house, they have no choice but to stay home all day, which can lead to those feelings of depression.
- Societal adversity – Desire to avoid the discomfort, dangers, and responsibilities arising from being among people. This can happen if other people are sometimes, or often, rude, hostile, critical or judgmental, crude, or otherwise unpleasant. The person would just prefer to be alone to avoid the hassles and hardships of dealing with people. There are some cases when not even seeing the sun long enough each day will affect them; by the time they try to go out and play, heart attacks and heat strokes are more common.
- Missing certain events – Special events are full of tradition and making memories. But if a person couldn't attend a special event, like a social gathering, dance, or any sort of outing of an event, the symptoms of isolation are on the rise, which could last for an indefinite period of time. Even if another person performed neglectful action to prevent one person from attending the event, this could instantly lead to isolation, along with other multiple symptoms, including nervous shock, which could cause the victim to keep itself secluded from any sort of future activity to avoid any further damage.
Social isolation can begin early in life. During this time of development, a person may become more preoccupied with feelings and thoughts of their individuality that are not easy to share with other individuals. This can result from feelings of shame, guilt, or alienation during childhood experiences. Social isolation can also coincide with developmental disabilities. Individuals with learning impairments may have trouble with social interaction. The difficulties experienced academically can greatly impact the individual's esteem and sense of self-worth. An example would be the need to repeat a year of school. During the early childhood developmental years, the need to fit in and be accepted is paramount. Having a learning deficit can in turn lead to feelings of isolation, that they are somehow 'different' from others.
Substance abuse can also be an element in isolation, whether a cause or a result. This can and many times does coincide with mood related disorders, but also with loneliness. According to a study that was conducted by Kimmo Herttua, Pekka Martikainen, Jussi Vahtera, and Mika Kivimäki, living alone can increase rates of being socially isolated and leading individuals to turn to the use of alcohol and other substances.
The loss of a loved one can contribute to social isolation. Studies have shown that widows who keep in contact with friends or relatives have better psychological health. A study conducted by Jung-Hwa Ha and Berit Ingersoll-Dayton concluded that widows who had a lot of social contact and interactions lead to fewer depressive symptoms. During a time of loss social isolation is not beneficial to an individual's mental health.
Whether new technologies such as the Internet and mobile phones exacerbate social isolation (of any origin) is a debated topic among sociologists. With the advent of online social networking communities, there are increasing options to become involved with social activities that do not require real-world physical interaction. Chat rooms, message boards, and other types of communities can meet the needs of those who would rather be alone, yet still develop communities of online friends.
Isolation among the elderly
Social isolation impacts approximately 24% of older adults in the United States, approximately 9 million people. The elderly have a unique set of isolating dynamics. Increasing frailty, possible declines in overall health, absent or uninvolved relatives or children, economic struggles can all add to the feeling of isolation. Among the elderly, childlessness can be a cause for social isolation. Whether their child is deceased or they didn't have children at all, the loneliness that comes from not having a child can cause social isolation. Retirement, the abrupt end of daily work relationships, the death of close friends or spouses can also contribute to social isolation. In the United States, Canada, and United Kingdom, a significant sector of the elderly who are in their 80s and 90s are brought to nursing homes if they show severe signs of social isolation. Other societies such as many in Southern Europe, Eastern Europe, East Asia, and also the Caribbean and South America, do not normally share the tendency towards admission to nursing homes, preferring instead to have children and extended-family of elderly parents take care of those elderly parents until their deaths. On the other hand, a report from Statistics Norway in 2016 stated that more than 30 percent of seniors over the age of 66 have two or fewer people to rely on should personal problems arise.
Isolation among children and teens
Middle school is a time when youth tend to be sensitive to social challenges and their self-esteem can be fragile. During this vulnerable time in development, supporting students' sense of belonging at school is of critical importance. Existing research finds that adolescents' development of a sense of belonging is an important factor in adolescence for creating social and emotional well-being and academic success. Studies have found that friendship-related loneliness is more explanatory for depressive symptoms among adolescents than parent-related loneliness. One possible explanation is that friends are the preferred source of social support during adolescence. Scientists have long known that loneliness in adults can predispose depressive symptoms later in life. Lately, they have also seen that lonely children are more susceptible to depressive symptoms in youth. In one study, researchers conclude that prevention of loneliness in childhood may be a protective factor against depression in adulthood. Socially isolated children tend to have lower subsequent educational attainment, be part of a less advantaged social class in adulthood, and are more likely to be psychologically distressed in adulthood. By receiving social assistance, studies show that children can cope more easily with high levels of stress. It is also shown that social support is strongly associated with feelings of mastery and the ability to deal with stressful situations, as well as strongly associated with increased quality of life.
