According to the research of Dr. John Cacioppo, loneliness has a major impact on your overall health – both mental and physical.
In his research, Dr. Cacioppo employed brain scans, monitoring of autonomic and neuroendocrine processes, and assays of immune function to test the influence that social connection has upon our health. His research showed how our perceptions, behavior and physiology are strongly affected by a loss of that connection.
In fact, Dr. Cacoppo’s research has shown that loneliness can cause:
These finding were presented by Dr. Cacioppo at the most recent conference of the American Association for the Advancement of Science.
According to Dr. Cacioppo, “healthwise, the difference between a lonely person and a popular person was akin to “a smoker and a non-smoker”. “That stunned all of us, myself and all my colleagues in terms of the effects it had,” he said. “It shows just how powerful it is.
“Loneliness lowers the ability to control yourself. It is really easy after a bad day to have a second scotch and a third to get some comfort.”
Dr. Cacioppo’s research has led him to believe that our need for connection can be traced back through our evolutionary roots.
In order to survive in the past, humans needed to bond to rear their children. In order to flourish, they needed to [increase their levels of altruism and cooperation]. Just as physical pain is a prompt to change behavior, such as moving a finger away from the fire, loneliness evolved as a prompt to action, signaling an ancestral need to repair the social bonds.
The problem of social isolation is likely to grow as conventional family structures die out, said Dr. Cacioppo. People are living longer, having fewer children later in life and becoming increasingly mobile around the world.
Surveys also show that people report significantly fewer close friends and confidants than those a generation ago.
All of this adds up to more loneliness and more health problems because of that loneliness.
According to the good doctor, we need to realize that “human beings are simply far more intertwined and interdependent—physiologically as well as psychologically—than our cultural prejudices have allowed us to acknowledge”. And if we don’t address our very real need for connection, we are risking our own psychological and physiological health.
“If you want to go fast,” says an African proverb, “go alone. If you want to go far, go together.”
