Yes, there may be a link between loneliness and depression. There are many studies that have looked into the relationship between both.

Information from the Centers for Disease Control and Prevention (CDC)Trusted Source notes that social isolation and loneliness may increase a person’s risk of depression.

Research from 2021Trusted Source looked into the relationship between loneliness and depression in people ages 50 years and older. The researchers found that loneliness was associated with an increased risk of depression and with increased severity of depressive symptoms. This increased risk remained up to 12 years after loneliness was reported.

A meta-analysis from 2020Trusted Source investigated loneliness in people between 11 and 30 years old who had depression. Researchers found that participants experienced loneliness for the following reasons:

  • Their depression hindered their social engagement, which led them to withdraw socially.
  • They preferred not to talk about their depression, leading to feelings of disconnection from their peers.
  • They desired a connection with others but felt unable to tolerate it.
  • They experienced a self-reinforcing cycle of loneliness and depression.

Overall, research suggests that there may be a bidirectional relationship between loneliness and depression. This means that loneliness may increase the likelihood of depression and vice versa.
