Loneliness – A Public Health Issue?

“Friendship is a lot like food. We need it to survive” –  Hara Estroff Marano, Psychology Today.

We humans have an inherent need to be part of a group, to form friendships, to interact and to socialise with people.  Evidence suggests that these are all necessary in order for us to maintain good health and wellbeing.  However, what happens when we only have part or none of the above, when we are unable to socialise, when we don’t feel like interacting, when we loose touch with friends and family?  It is likely that we will feel a sense of loneliness, and this, the experts say, can be detrimental to our health.

Since the 1990’s an increasing number of studies measuring the impact of loneliness suggest it is an important public health concern.  The evidence reveals that the risk of developing and dying from heart disease can depend on the strength of one’s social network of friends and family.

What is Loneliness and how does it arise?

Loneliness, although easy to describe is harder to define because of its many dimensions.  Wikipedia defines loneliness as an unpleasant feeling in which a person experiences a strong sense of emptiness and solitude resulting from inadequate levels of social relationships.  Loneliness is however a subjective experience, in that, if a person thinks they are lonely, then they are lonely whether they are in solitude or in the middle of a crowd. 

The mental Health Charity MIND, believe that loneliness is a very intense feeling and "to feel lonely is to be overwhelmed by an unbearable feeling of separateness, at a deep level”. 

It is likely that many of us will have experienced loneliness at some point in our lives.  For some it may be a temporary feeling, resulting from certain events, while for others, it could feel like a permanent part of life. 

Loneliness can occur for a number of reasons and as highlighted above can depend on a persons state of mind.  However, feelings of loneliness may arise from losing connection with others through death, breakup of a relationship, moving away, being immobile or ill and working longer hours, or from being unable to form new connections due to shyness or lack of confidence.

A report called The Lonely Society? commissioned by the Mental Health Foundation, found that the way in which people now live is impacting on their ability to connect with others. More people live alone: the percentage of households occupied by one person doubled from 6% in 1972 to 12% in 2008. The divorce rate has almost doubled in the past 50 years and the number of lone parent households is rising. People are living longer but many older people are doing so alone. Because of people pursuing careers and education opportunities, many now live further away from their families and the communities they grew up in. 

The Health Implications of Loneliness

Loneliness, although a natural emotion, can be detrimental to our physical and mental health.  One of the main reasons why loneliness has negative implications is because it makes it harder for us to control our habits and behaviour.  A book written by John T Cacioppo and William Patrick entitled "Loneliness: Human Nature and the Need for Social Connection" suggests that loneliness leads to self destructive habits, such as overeating, relying on alcohol and avoiding physical exercise.

In their numerous studies, they reported that not only do lonely people tend to withdraw from society (becoming further isolated) but they express higher levels of stress and difficulties sleeping, leading to diminished restorative processes.  Tests also show that loneliness affects the immune and cardiovascular systems and that there is a strong correlation between loneliness and depression.  The Lonely Society report? found that four in ten people (42%) have felt depressed because they felt alone.

James J Lynch, loneliness expert and writer of  "A Cry Unheard: New Insights into the Medical Consequences of Loneliness" describes loneliness as a silent epidemic that is harming public health, leading to depression and early death.  He proposes that causes of death are notably higher for “divorced, single, and widowed individuals of both sexes and all races."

Cacioppo points out that, “being connected with others is so necessary to survival, that human brains have become hard-wired to seek regular social contact”. 

How Lonely are We - The Statistics

The UK report by The Lonely Society? reveled that 48% of us believe people are getting lonelier in general.  Only 22% of us never feel lonely and one in ten (11%) of us feel lonely often.  A third of us (37%) have a close friend or family member who we think is very lonely and over half of us (57%) who have experienced depression or anxiety isolated ourselves from friends and family.

The pain of loneliness is the sharp end of a milder feeling of social disconnection that research suggests is widespread: a recent Emotional Needs Audit of the UK by the Human Givens Institute, which involved 4,600 online respondents, reported that 24.1% of people did not feel emotionally connected to others; 34.8% did not feel connected to the wider community and 35.4% felt they did not receive enough attention.  The lonelier our society, the more likely we are to experience loneliness.

Coping with Loneliness

Loneliness is clearly a health concern, and we need to seek ways of overcoming it.  Making the effort to spend time with a friend or family can have a two way effect.  It will allow you to socialise and feel good as well as having a positive impact on the other person.

The UK mental health charity MIND, offers several suggestions on how to overcome loneliness.  Some of these include; learning to be with others, joining a class, a local interest group or volunteering for something.  For further information on dealing with loneliness click here to go to the MIND website.
