The Physical and Emotional Effects of Loneliness in Adults

The Physical and Emotional Effects of Loneliness in Adults

The Merriam-Webster dictionary defines loneliness as “being without company” or “cut off from others”, and refers to this as producing feelings of desolation and sadness from being alone.  The UCLA division of geriatric medicine has found that, while 43 percent of older adults said they felt lonely, only 18 percent actually live alone.  In other words, we can have rich lives, surrounded by many, yet feel the emptiness of being alone.  They also noted that approximately 60 million Americans (equal to one-fifth of our population) has the sense of loneliness at some point in their lives.  Therefore, we should be aware of how loneliness can impact our health.

While loneliness may lead to depression, they can be very different.  Depression leads to a sense of low motivation, low energy and a lack of enjoyment.  Those who suffer from loneliness may be fully functioning, yet have that nagging sense of emptiness.

Unfortunately, those who feel lonely or isolated can also get caught up in a self-fulfilling prophesy or loop.  Those who are lonely are more likely to see the world as a threat, and always be “on guard”.  They may remember more negative experiences or social information, and also expect negative social interactions.  This can lead to stress, anxiety, low self-esteem, pessimism, and even hostility.

The impact of loneliness goes beyond the emotional effects.  Researchers at UCLA have also found that of those who are lonely, 25 percent are more likely to die prematurely.  They also have a greater risk of heart disease, Alzheimer’s, stroke, metastatic cancer, and also are more likely to have illness and inflammation.  Poor sleep, misuse or abuse of alcohol and obesity are also seen in this group.  John Cacioppo, a researcher at the Center for Cognitive and Social Neuroscience found that gene expression is different in those who are lonely.  Their research showed that there is actually a molecular (cellular) change that leads to these health effects.

Naomi Eisenberger, a researcher at the Social and Affective Neuroscience Laboratory was also able to show that there is a connection between loneliness and physical pain.  In the study, a virtual game was set up online.  A ball was passed between participants, using this online format, then it was intentionally stopped.  Eisenberger and her team noted reactions that ranged from people taking this personally and having hurt feelings to those who stated “I didn’t care about it anyway”.  The reactions were correlated with brain scans of the participants.  Those with hurt feelings (or rejection) had brain scans that showed a response in the part of the brain that deals with pain.  The researchers took this a step further, and found that when they gave acetaminophen (generic Tylenol) to those with emotional pain, the same dose was as effective as those with physical pain.  So, we now know that when we are hurt emotionally, we actually physically feel pain as well.

Loneliness and isolation is especially significant in our elderly, and even more so in those who may not have family to count on.  As a family member, friend or neighbor you can impact those who are lonely.  A Place For Mom lists “14 Ways to Help Seniors Avoid Isolation” and are as follows:
