Physical Effects of Loneliness

In part one of the loneliness series we started to look at the mental effect’s loneliness can have on individuals. Stress, poor sleep quality, substance abuse, negative self-image and feeling withdrawn are some symptoms of loneliness. Part two of the loneliness series touches on the physical side of loneliness.

Physical Effects of Loneliness

Loneliness is an unfortunate part of life sometimes - a feeling we are all familiar with and have our own methods to overcome. For some, however, it may be difficult to combat loneliness. Worse yet, it can have adverse health effects if left unmanaged for too long.

Chronic loneliness is a serious condition in which the person suffering from it is often depressed and unable to feel a sense of closeness with friends, family and their loved ones - no matter how often they are in their company. Despite the categorization of loneliness as psychological or social pain, it can have extreme physical effects on the body over time as well.

Higher Blood Pressure & Heart Conditions

Hypertension or HBP is a lifelong condition that increases your risk of heart attack and stroke. In a 2016 Harvard Health Men’s Watch article reviewing 23 studies on loneliness found that loneliness and social isolation increased risk of heart attack by 29% and 32% increased risk of stroke. Making these risks inline with light smoking and obesity.

And in fact, it was revealed that even people who experienced modest levels of loneliness were also affected. However, they were at less of a risk than people suffering from chronic loneliness. Blood pressure is as much as 30 points higher in people who experience loneliness than people who do not.

Loss of Sleep

Research from the University of Chicago suggests that there is a connection between loneliness and insomnia. The study revealed that lonely people slept about 30 minutes less than other people. Depression is often associated with insomnia and may play a major role as to why people suffering from loneliness experience a loss of sleep.

Dietary Issues

A study published in Nutrition Reviews revealed that people who live alone are more likely to suffer from a poor diet, due to a lack of important food groups such as fruits and vegetables. People suffering from loneliness are less motivated to cook meals for themselves and instead turn to ready-made meals or take out that very often lack key nutrients. Poor dietary choices may lead to weight gain, lack of energy and increased health risks.

Effects of Hormonal Imbalance

The stress hormone known as cortisol is a very prevalent and dangerous issue in people experiencing loneliness. In fact, increased cortisol levels can be linked to most of the side effects of loneliness, some of which include weight gain, fatigue, gastrointestinal issues and depression.

Prolonged cortisol production due to chronic loneliness can take a toll on your immune system, making it difficult to fight off infection and illness. It also raises prolactin levels, which increases your sensitivity to pain, making muscle aches and headaches seem worse than they actually are. Excessive levels of cortisol hyper-sensitizes your brain to pain, so headaches may happen very suddenly due to even slight nerve activity.

When you think about it, being lonely is just as bad for you physically as it is mentally. Think about all the conditions mentioned here, the next time loneliness strikes. Remember, by doing all that you can to interact with people, you'll be helping your physical being as well. Look for groups that have similar interests as you to help you get out of the house and start interacting again. Inch by inch it’s a cinch as someone once said.

In our next article, we delve into how social media influences loneliness.

Stay strong my brother!
