The Loneliness Epidemic

1 in 4 Americans say they sometimes or always feel lonely, according to a new study from Cigna. That’s up from 48 percent in 2018. The findings are part of the Cigna US Loneliness Index, which surveyed more than 20,000 adults across the United States.

The Prevalence of Loneliness

While loneliness is not as commonly discussed as depression, it is a very real and prevalent problem. In fact, a recent study by Cigna found that nearly half of all Americans report feeling lonely. And, loneliness can have a significant impact on mental health, with research finding that it can increase the risk of developing depression.

So, what exactly is loneliness? And, can it cause depression? Let’s take a closer look.

What is Loneliness?
Loneliness is an emotion that everyone experiences at times. It is characterized by a feeling of being isolated and disconnected from others. While everyone feels lonely from time to time, some people experience chronic loneliness. This is defined as feeling lonely more often than not and can have a significant impact on mental health.

Causes of Loneliness
There are many factors that can contribute to feelings of loneliness. These can include social isolation, loss of a loved one, relationship problems, and moving to a new place. Additionally, certain health conditions and medications can also lead to feelings of loneliness. For example, older adults who live alone may feel lonely due to declining physical health or decreased social interaction. And, people with mental illness may also be more likely to feel lonely due to the negative impact of their symptoms on social interactions.

The Consequences of Loneliness

Loneliness doesn’t just make you feel bad, it can also have a negative impact on your health. Studies have shown that loneliness can lead to a number of different health problems, including:

-High blood pressure
-Heart disease
– Obesity
– Diabetes
– Sleep problems
– Depression
– Anxiety

It is common for people to feel lonely from time to time. However, when loneliness is constant or starts to interfere with daily activities, it may be a sign of depression. ln fact, research has shown that there is a strong link between loneliness and depression.

The Relationship Between Loneliness and Depression

There is a strong link between loneliness and depression. Loneliness is defined as a negative state that results from a discrepancy between the amount of social interaction that a person desires and the amount of social interaction that he or she actually experiences. Depression, on the other hand, is defined as an extended period of low mood and aversion to activity. Although loneliness and depression are two separate entities, they are often comorbid, meaning that they occur together. The relationship between loneliness and depression is bidirectional, meaning that each can cause the other.

The Direction of the Relationship

Research suggests that there might be a bidirectional relationship between loneliness and depression. This means that not only can loneliness lead to depression, but depression can also lead to feelings of loneliness. A 2013 study looked at this relationship in a group of older adults. The study found that those who were struggling with symptoms of depression were more likely to feel lonely. And, the participants who reported feeling lonely were more likely to develop symptoms of depression six months later.

The Implications of the Relationship

Loneliness has been found to be a significant predictor of depression (K alone & Bolus, 1993; Hawkley, Thisted, Masi, & Cacioppo, 2010). In a study of female twins, heritability for loneliness was .30 (Boomsma, Van Tol, & Van Duijn, 1985).

The Importance of Social Connection

Humans are social creatures. We need social interaction in order to thrive. In fact, research has shown that social isolation can have some pretty serious implications for our mental and physical health.

One study found that social isolation was a greater risk factor for early mortality than obesity or smoking. Other research has shown that loneliness can increased inflammation, worsen heart health, and lead to depression.

So, it’s pretty clear that maintaining social connections is important for our overall wellbeing. But what about the quality of those connections?

It turns out that not all social interactions are equal when it comes to their benefits for our health. A study from UCLA found that participants who had close, satisfying relationships were more likely to live longer than those who had weaker relationships.

It’s not just the quantity of our social interactions that matters, but also the quality. So make sure you’re spending time with people who make you feel good and who you can count on in times of need.

The Takeaway

Overall, the relationship between loneliness and depression is complex. There is no one-size-fits-all answer to whether loneliness causes depression or vice versa. It is likely that the two factors can interact with each other in a vicious cycle, making it difficult to determine which one came first. If you are feeling lonely or depressed, reach out to a trusted friend or family member, or seek professional help.
